This dish you're seeing is crispy squid.
Squids are a type of mollusca. Swimming through the ocean doing their thing. But is farming and/or capturing these marine creatures worth it for the dish?

The squid population is increasing. There's both positives and negatives to this. One positive is that there is more food for predators. One negative is more prey will have to fight for food. There's also an economic standpoint. Fish prices fluctuate wildly depending on the ecosystem bellow.

Octopus populations are also rising, although out of all the cephalopods, octopuses make up about 31% of the cephalopods. They may not be the majority, but the populations are still rising. What can be said here can also be said for the squids. Both negative and positives of the population boom.

Fast-breeding cephalopods exploit gaps left by extreme climate change and overfishing

Squid, octopus and cuttlefish populations are booming across the world. These fast-growing, adaptable creatures are perfectly equipped to exploit the gaps left by extreme climate changes and overfishing, according to a study colleagues and I published in the journal Current Biology.

Humans have reached and in many cases surpassed sustainable fishing limits, as our growing population demands more food. In terms of the food web, we tend to start from the top and fish “downwards”. Fishermen fish out the top predators first, including large sharks, tuna and whales, and then medium size fish such as cod, hake and halibut that usually live long and grow slowly.

The vacant space left by fish may be occupied by other species, with rapidly proliferating animals having a clear advantage. And these animals are cephalopods. Squid, octopus and cuttlefish live in the “fast lane”, growing quickly and typically living for only one or two years. They produce lots of eggs, and their eggs have relatively low mortality rates, whether thanks to patient brooding by an octopus mother or the protective mucous that covers embryonic squid. These traits enable cephalopods to adapt rapidly to changes in the environment which have become even more pronounced in recent decades thanks to human activity.

Counting cephalopods

These are elusive creatures, notoriously difficult to count. To get a better estimate of their overall abundance, we looked at what we call catch rates —how many were caught per vessel per unit of time —over the past six decades. We used an extensive dataset of 35 different species (52% squid, 31% octopus and 17% cuttlefish) from all major oceanic regions. Most were “target” species deliberately sought by fishermen, others were non-target or bycatch species. We used data from both regular commercial fisheries and specific research surveys.

Everywhere we looked we found a substantial and statistically significant increase. Bottom-dwelling octopus and cuttlefish who live relatively static lives are thriving, as are squid that hover over the bottom, along with those in the open ocean that may travel thousands of kilometres from spawning to feeding sites. At a time when life in the oceans is threatened, cephalopods seem able to buck the trend.

Extreme climate changes lead to population explosion

The “jumbo squid” represents one of the most striking examples. Also known as the Humboldt squid, it typically weighs around 1-2 kg and has an annual life cycle. It lives in the warm waters of the eastern Pacific and has supported small-scale fishing in Mexico, Chile and Peru.

However, a strong hot season of El Niño followed by a cold season of La Niña can do funny things to these squid. The colder waters during a La Niña delay their maturation and allow them to survive into the next year, giving them a two-year life cycle. But during this second year they continue to grow fast meaning that by the end of their two years they attain much larger sizes. In fact, these climate events have triggered the establishment of large bi-annual groups of squid weighing 25-40 kg—ten times their normal size.

After the El Niño/La-Niña events of 1997-2000 these squid began to make their way up the Pacific coast to northern California reaching Alaska, leading to the recent development of one of the world’s largest squid fisheries. The total annual catch of 600,000 to 1m tonnes has become extremely important for coastal livelihoods of eastern Pacific countries.

However, as the jumbo squid’s “switch” from one to two year life cycles depends on ambient water temperature, another strong El Niño event may cause almost complete disappearance of the large group, returning the populations to their “normal condition” as a medium size annual breeder. This has happened recently in Mexico’s Gulf of California causing havoc to local squid fisheries, and it may also happen in Peru and Chile, another region where a strong El-Niño event is currently occurring.

Planet of the octopus?

The boom in squid, octopus and cuttlefish will have interesting consequences both for their own ecosystem and for human society. On the one hand, it could benefit the sharks, whales and large fish which are reliant on them for food, along with certain fishermen.

However, cephalopod populations are much less stable than fish with longer lives. Usually they follow a “boom and bust” strategy, varying in biomass by several orders of magnitude from year to year, changes that are notoriously difficult to predict. Fishing profits can vary hugely in line with fluctuating populations, and high conservation and economic risks are often exacerbated by the relative lack of co-operation and communication among industry participants.

As fisheries continue to refocus their efforts towards cephalopods, it becomes critically important to manage stocks appropriately so they do not face the same fate as many fish in the recent past.

Squid is well known for being cheap, versatile, and tasty. It's a good source of protein, vitamins, and cholesterol. One thing to note is seafood may contain mercury. Squid cuisine may also trigger shellfish allergies. So that's something to be aware of.

# data[].attributes.attachment_link.readable_text
Squid is a popular seafood all over the world. It's cheap, versatile, and tasty. It can be grilled, seared, boiled, braised, and even eaten raw as sashimi.

One of the most popular preparations of squid is chopped, breaded, and fried. This is popularly referred to as calamari, though the term 'calamari' technically encompasses any squid eaten as food. Fried calamari has more calories than most other preparations of calamari.

Commercially fished squids are typically caught offshore, sometimes far out at sea. Many different squid species are fished and eaten. In 2002, the most commonly caught squid species were the European squid, the Argentine shortfin squid, the jumbo flying squid, and the Japanese flying squid. The jumbo flying squid fishery is currently the most productive in the world.

Clearly, there's high demand for squid. This begs the question, what health benefits and risks come with squid consumption?

Potential Health Benefits of Squid

The health benefits of squid are often linked to its high protein content. Other benefits are tied to its polyunsaturated fatty acid content, also known as omega-3 fatty acids.

The U.S. Food and Drug Administration highlights fish as a healthy food for those who are pregnant and breastfeeding. The protein and iron content of squid are considered particularly important for women who are pregnant.

The link between omega-3 fatty acids in fish oil and heart health has been well researched. However, the balance of fatty acids in calamari oil is somewhat different than in typical fish oils on the market.

The fatty acid docosahexaenoic acid (DHA) is higher in squid than in other seafood. DHA has been shown to improve resting heart rate. DHA-rich oils, like calamari oil, may also help reduce platelet aggregation for women.

Research on the omega-3 fatty acids found in seafood indicates that they help soothe the symptoms of rheumatoid arthritis. Participants in a study reported shorter periods of morning joint stiffness and reduced joint swelling and pain.

Octopuses are (like squids) high in protein, vitamins, and other metals like iron, sodium and zinc. Octopus is quite squishy, so if you have sensory issues, it may not be an ideal choice. There's also the risk of octopuses having mercury and arsenic. They also count as shellfish, so if you have a shellfish allergy (like meee) it's best to decline.

This article discusses the booming population of squid. The most likely cause is global warming. With the information, it can be argued that squids are safe to form, at least in terms of sustainability. The population boom, however, may not be as structurally sound.

Researchers have measured a 39-fold jump in squid numbers in the Pacific Northwest that can directly be linked to ocean heat waves.

A new study, published in the journal Marine and Coastal Fisheries, has found that the rising amount of ocean heatwaves, triggered by climate change, has a direct effect on the population numbers of the squid species Doryteuthis opalescens which primarily was known to inhabit the warmer waters off Baja California.

According to the study, the population numbers of the species have significantly increased between 1998 and 2019 along the Pacific coast, with Washington seeing a 39-fold increase in squid populations and Oregon recording a 25-fold increase.

By examining fisheries-independent survey data collected by the National Marine Fisheries Service, the researchers were able to develop a spatiotemporal model that shows squid density changes from central California to northern Washington from 1998 to 2019.

"Although our model demonstrated that encounter rates and squid densities for the surveys increased in warmer and more saline waters, large shifts in squid distribution were only associated with deviations in ocean temperatures that could be characterized as marine heatwaves," the study reads.

The sharp rise in squid populations further north is believed to be directly linked to a series of marine heatwaves, also referred to as 'the blob' that was also recorded off Washington numerous times.

It is still unclear whether the population changes are permanent or temporary. Further ecosystem assessment models are needed to forecast the changes, according to Mary Hunsicker, co-author of the new research: "If we can develop models that account for these relationships, we may be able to better predict what these changes mean for species and their predators and the coastal communities that depend on them."

The study comes after a separate report by the US National Oceanic and Atmospheric Administration (NOAA) last month stated that southeast Alaska is seeing more individuals of the species, also linking the increase to climate change. "It gives credibility to the possibility that they are establishing a population in Southeast Alaska under large-scale sustained warming," John Eiler, Alaska Fisheries Science Centre biologist, said.

Octopus populations have also experienced a population boom. However, it's causing trouble for the economy. Octopuses have been eating all the available shellfish. This doesn't just cause a problem with the market. Other species rely on those shellfish. Even tourist have spotted the eight-armed(?) swimmer. Too much of somethings results in too little of something else.

When Chris Chesterfield goes to pull up his pots, he usually expects cuttlefish or spider crabs. But lately the Cornish fisher has been finding himself ambushed - and outnumbered.

"You've only got one or two arms pulling them up," he says, "and they've got eight pulling you down."

Unprecedented numbers of octopuses have been reported in the waters off Cornwall in recent weeks, prompting celebration and concerns of a "population explosion".

"I've been fishing for 40 years and I've never experienced this amount," says Cameron Henry, from Mylor, who fishes with his two brothers.

He first became aware of the increase in late May, when he started pulling up lobster and cuttlefish pots that were conspicuously empty after an eight-legged thief got to the bait or bounty first. "We had no shellfish - only remains of shellfish."

Within days Henry was catching the culprits too, sometimes two or three to a pot: "You can imagine how fun it is to get them out."

For Chesterfield, who operates alone from Mevagissey in his 30ft trawler, the octopus overload poses an even greater logistical challenge.

The largest specimens stretch 1.2m (4ft) when suspended over the deck - if you can get them to stay still long enough, he says. "They just throw their tentacles over the top of you and turn inside out, literally. When they come out of the pot, they stick to the deck, stick to your legs - it's endless."

In one day in early June, Chesterfield says he caught 260kg of octopus, amounting to about 150 creatures. In a typical year he would expect to catch half a dozen.

"There's been loads of days when you're pulling 100kg, no problem at all," he says. "Sometimes there's five or six in one pot."

The Cornwall Wildlife Trust, which coordinates volunteer monitoring of local marine life, says the "huge" numbers of octopus sightings in the region recorded not only by fishers but divers and snorkellers point to a rare population boom.

Despite its name, the common octopus ( Octopus vulgaris) is a rare sight in British waters, says Matt Slater, the trust's marine conservation officer. "In an ordinary year, we'd only expect a couple of sightings and a couple of very excited divers - but now we're getting reports all the time, which is great."

Like many octopuses, the species lives only one or two years but produces as many as 500,000 eggs, meaning favourable conditions can lead to massive fluctuations in populations.

According to records kept by the Marine Biological Association, the last such event along England's south coast was more than 70 years ago, in the summer of 1948. Earlier a "plague" of octopuses was described in 1899.

"It got to the point where fishermen were really worried about their livelihoods," Slater says. "They were finding them in rock pools and even laying eggs there, which is not normal."

Although octopuses are considered by some to be a delicacy, there is less demand for them from UK consumers than for the crustaceans they eat, leading to concerns among fishers that they would be competing for their catch this summer. "We're seeing so many that it wouldn't take them long to fish out an area," Henry said.

He has readily sold the octopus that he has caught so far, but warned that if numbers continued to spiral it could pose a problem: "You'll end up flooding the market, the price will go out and you'll end up not being able to get rid of it."

He and Chesterfield say that sightings have dipped in recent days, suggesting that this particular consortium may be moving on - to venture either around Land's End or out to sea.

It is, however, possible that octopus booms could become more frequent in the future. Like jellyfish, octopuses have been found to be adapting faster than other species to the changing marine ecosystem. Many species have already been found to have expanded their ranges with warming waters, while a study published last year found octopuses may also be able to withstand changes in acidity levels better than other species.

Slater, at least, is enthusiastic about the boom. A card-carrying member of the cephalopod squad, he used to work at an aquarium and says individual animals came to recognise his face and favoured him over other staff.

"A plague of octopus, for me, is something to be celebrated," he says. "I've been hoping that one day I might see one of these big population explosions, and it feels like this could be a bumper year."

Slater encourages members of the public to report any octopus sightings on the Cornwall Wildlife Trust's website - but Henry and Chesterfield, on the frontlines, fear being overrun.

Both say they "humanely dispatch" their octopus catch quickly with a knife between the eyes, to the creature's central brain. That is so "we haven't got them crawling all over the boat, like in previous years", says Chesterfield. "They were long, hard days until we found that out."

Squids are marine cephalopods with eight arms and two long tentacles, typically able to change color.

The squid is one of the most highly developed invertebrates, well adapted to its active, predatory life.

There are more than 300 known species of squid out there that have been identified.

Squid are known to inhabit almost every major body of saltwater on the planet and even some bodies of freshwater. Many squid are adept at surviving in cold, oxygen-deprived waters deep below the surface.

The largest quantity of squid species are found throughout the North Atlantic Ocean. The North Pacific is also home to a variety of squid types.

Most of squid species will be found at least 300 meters (1,000 feet) below the surface. The water is cooler there and they can be alone.

The lifespan is 6 months for the smaller squid and up to 5 years for the larger ones.
The smallest squid is the pygmy squid which can be less than 2.5 centimeters (1 inch) long while the largest is the colossal squid which can be up to 14 meters (46 feet) in length and weighing possibly up to 750 kg (1,650 lb).
Squid have gills just like fish.

Squid have three hearts. Two branchial hearts feed the gills, each surrounding the larger systemic heart that pumps blood around the body.

Squid blood is blue, not red as in humans. This is because squid blood contains a copper-containing compound called haemocyanin. In humans the blood is red and contains the iron compound haemoglobin.

The skin is covered in chromatophores, which enable the squid to change color to suit its surroundings, making it practically invisible. The underside is also almost always lighter than the topside, to provide camouflage from both prey and predator.

The main body mass is enclosed in the mantle, which has a swimming fin along each side.

They move through the water tail first instead of head first.

A squid moves using a system of jet propulsion, pulling water into its mantle cavity, contracting the muscles of the mantle wall and expelling the water through its siphon or funnel. Its fins aid maneuverability and also help with lift and motion while the squid travels at slow speeds.

Squid are strong swimmers and certain species can " fly " for short distances out of the water.

Squid are able to reach 40 km/h (25 mph), making them the speediest marine invertebrates.

All squid have a sac of ink inside the mantle. The ink is a dark liquid and is expelled through the funnel. If the squid meets a predator, it shoots out a cloud of ink, which hides the squid so it can escape.

Squid and octopus have an intricate nervous system, more complex than other molluscs, and invertebrates in general.

Some species of squid are able to glow in the dark. Research shows this is due to them having bioluminescent organs.

The eyes, on either side of the head, each contain a hard lens. The image is focused by changing the position of the lens, as in a camera or telescope, rather than changing the shape of the lens, as in the human eye.

Squid can hear, scientists have confirmed. But they don't detect the changes in pressure associated with sound waves, like we do. They have another, more primitive, technique for listening: They sense the motion generated by sound waves.

They have small teeth on the sides of their tongue. But their primary weapon is their beak which is similar to a parrot's. They use it to catch its prey and tear it into manageable pieces.

All squid are carnivores and eat mainly fish, shrimp, crabs and even other squid. They are ambush predators, often relying on stealth to sneak up on prey and capture it before it can escape.

Some squid species live in schools like fish and some are solitary.

When it is time for the mating to occur large groups of males and females come together at dawn and start swimming rapidly in large circles. After a while you can see two squids swimming together. These will be the ones starting the mating.

After a male and female mate, the female squid lays eggs. Thousands of eggs can be produced at a time by one female. She will distribute them in hidden areas of the water including under rocks or in various holes and crevices she can find. It can be up to eight weeks before those eggs hatch so keeping them save from predators can be difficult. The female squid don't wait around for them to hatch, they leave after depositing them.

The squid's natural predators include birds, fish, sharks and whales.

Some species of squid have been found to live more than 4,000 meters (13,000 feet) deep in the water.

The giant squid have eyeballs that are the same size as a standard basketball.

Squid ink contains dopamine, a neurotransmitter that in human brains, produces the sensation of euphoria. It is not known what role it plays in squid and why it is in the ink.

The " fire shooter squid" formally known as Heteroteuthis Dispar, is squid that shoots out a cloud of light from bioluminescent photophores, to distract predators.

Neuroscientists in training learn the basics of neurosurgery by practicing on Loligo pealei squid. Their thick axon, thicker than any human nerves, is easier to start with.

Giant squid are featured in literature and folklore with a frightening connotation. The Kraken is a legendary tentacled monster possibly based on sightings of real giant squid.

Many species are popular as food in cuisines as diverse as American, Basque, Canadian, Chinese, English, Filipino, Greek, Italian, Japanese, Korean, Portuguese, Spanish, Tunisian, Turkish and Vietnamese.

Calamari is a culinary name for squid, especially for dishes from the Mediterranean, notably fried squid (fried calamari). There are many ways of preparing and cooking squid, with every country and region having its own recipes.

Some fun facts about octopuses.

Like squids, they have three hearts.
Both male and females die soon after mating.
~2/3 of their nerves are found in the "arms".

# data[].attributes.attachment_link.readable_text
Depending on who you talk to, octopuses are either soulful, sophisticated creatures or the stuff of deep-sea nightmares.

Indeed, they're often fictionalized as slimy, eight-armed monsters that lurk in wait of prey. But get to know them a little better, and you'll find that these cephalopods are, though strange and alienlike to behold, also totally fascinating creatures.

Here are 10 things you might not have known about octopuses (and yes, the plural is , not octopi!).

1. Octopus arms have a mind of their own.

About two-thirds of an octopus's neurons are actually located in its arms. This means the arms can taste, touch, and even act on their own accord, without input from the brain.

Some research has even found that after an arm is severed from the body it will continue to snatch up food and try to move it in the direction of where the creature's mouth used to be.

2. They have (literally) a lot of heart.

Octopuses have not one, not two, but three hearts. Two of them pump blood to its gills, and a third heart keeps circulation flowing to the organs. This third heart stops every time the octopus is swimming, which may explain why they prefer to crawl (you'd get tired too, if one of your hearts stopped!)

BONUS FACT: As for the blood the hearts are pumping around? It's blue, thanks to a pigment called hemocyanin.

3. Males die after mating, too.

Mating isn't all that much better for males. Once they've done their part in the reproductive process, their lives accelerate towards their end.

Males can only live for a maximum of a few months after mating.

4. They're masters of camouflage.

Blending in means a better chance of survival.

Luckily for octopuses, they can completely change their skin color and texture in under a second.

Contrast that to the famed chameleon, which can take several minutes to transform.

5. Females give their lives to protect their eggs.

A female octopus can lay up to 400,000 eggs. From the moment they're laid she spends her life protecting them, night and day -even giving up eating while she focuses on her egg-guarding duty. Typically, the eggs take at least five months to hatch, though one deep-sea octopus was observed to guard her eggs for almost 4.5 years! Job done, the female octopus will die shortly after her eggs are hatched.

6. They're smart enough to use tools.

It used to be thought that only vertebrates were smart enough to use objects as tools. Not so: some octopuses have been observed hoarding two halves of a coconut shell, which they carry around like a mobile home and assemble together when needed. Aquarium staff probably aren't so surprised. Octopuses in captivity regularly solve puzzles, open jars, navigate obstacle courses, and even find cheeky ways to escape their tanks.

7. They sometimes build underwater cities.

In 2017 scientists discovered an underwater octopus city, which they cleverly named "Octlantis", off the coast of Eastern Australia.

It was populated by a species called the gloomy octopus which was previously thought to be solitary. The scientists witnesses complex social behaviors occurring in the population of 15 octopuses, who were living together, communicating, and even evicting each other from dens. It was the second such city found in the area after a first - "Octopolis" - was discovered in 2009.

8. They have some cool defensive tricks up their many sleeves.

Imagine you're an octopus under attack. If your camouflage skills aren't cutting it, you might want to detach one of your arms and let it crawl off on its own - the old decoy trick to distract the predator. Octopuses can actually do this and, as you know, grow the arm back later. They can also use their ink as a defense. Sprayed into the water, it reduces a predator's vision and sense of smell.

9. They can regrow limbs.

If an octopus loses an arm - no problem! They have an impressive regenerative process that kicks in and allows them to develop a new one.

They're also really good at it. When lizards regrow their tails, for example, the new one is often inferior. With octopuses, a regrown limb is basically as good as new.

10. They can be deadly.

Australia's blue-ringed octopus is considered to be one of the world's most venomous marine animals. Though only 5-8 inches in size, one octopus can carry enough venom to kill 26 adult humans and all within a matter of Their potent venom contains tetrodotoxin, which is 1,200 times more toxic than cyanide.

As far as I know, squid populations aren't in any danger, they may be the safest to eat, at least for the ecosystem. There's always dangers in food, be it allergens, contamination, etc.
The most we can really do is just keep an eye out. It really depends on morals.

What can be said here can also be said for the squid. Although, seeing a recipe call for baby octopuses, it's morally questionable.
