- It is at the coastal bay so it would be usually very hot and sunny so solar energy can be used to obtain the energy required to run the farm
- Since it is coastal bay farm not much energy is required so this can help save cost and obtain enough energy to run the farm
- Energy is required to run the farm because it helps in the pumping( if required), transporting , refrigeration, aeration (if required), computer for monitoring the fishes]]> 2021-11-18 05:35:43 UTC https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898741249 Management of Resources 200187881 https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898742273 Importance to the industry:
  • For long-term sustainability 
  • Proper management of fishes shows consumers that the fish is safe to consume.
  • Laws, Permits and Certifications shows the credibility of the facility so it sets a standard to other facilities to follow.
  • Managing distribution of resources so that each industry is able to receive sufficient resources.
  • Environmental conservation 
  • Proper management of broodstock ensures that...
    • issues of inbreeding is prevented
    • maintain desirable traits of fish
    • wild stocks are not exploited

Management put in place:
  • NOAA Fisheries & North Pacific Fishery Management Council (Pacific Coast Groundfish Fishery Management Plan)
    • Limitations on harvested amount in 1 trip
    • Fishing halt during certain seasons & at certain areas
    • Restriction of gears: reduces by-catch & damage to habitats
  • Gulf of Alaska & Bering Sea/Aleutian Islands (Groundfish Fishery Management Plans)
    • Requirement of permits: limits fishing activity
    • Determine amount of perch that can be caught (quota)
    • Record keeping, Reporting, Monitoring

- Facility is located along the coastline ]]> 2021-11-18 05:42:40 UTC https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898748818 Water-Powered Energy https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898758025 Since farm is near coastal areas with constant waves and water movement, this can be used to the farm's advantage.
By using water energy turbine, this machinery can make use of the coastal waves to generate electricity for the farm to use. 
- Cuts down electricity usage and bills
- Saves money 
- Efficient as it makes use of its location being near coastal area ]]> 2021-11-18 05:51:37 UTC https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898758025 Water resources https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898760378 Inlet: Nearby river / stream

  • Water Resource: Water Resource Department (Water Rights). Costs about $2,000 and has to be renewed annually.
  • Water-Powered Energy: The Oregon Department of State Lands, United States Army Corps of Engineers (Works in navigable water/wetlands). Permits & gives authorization for the construction of any structure in water.
  • Aquafeed Resources: Oregon Department of Fish & Wildlife (Fish transport permit): Permit to import live fish/eggs.
The waste produced from the facility has to be managed too, to conserve the environment.
  • Department of Environmental Quality (Pollutant Discharge): Monitors & regulates waste discharged from the facility.

-Live feed can be obtain from the ocean nearby 
- However, this is a non-sustainable practice

Establishing a farm next to a coastal bay would mean extensive resources used for water supply in any type of aquaculture system used for perch (typically RAS).  Recirculating aquaculture systems permit year-round culture of yellow perch and faster production cycles. However, RAS are expensive to construct and also require higher operational costs, redundant safeguard systems, and a fairly significant amount of training and/or learning time to efficiently operate. Thus, cages are used as perch have shown to perform well in cages, but grow-out also appears to take two to perhaps three years. ]]> 2021-11-18 06:21:07 UTC https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898791216 Diet https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898791333 In many culture species, a lack of understanding of nutritional requirements has been a problem. Yellow perch have yet to be given a commercially available specialist diet, hence they are normally fed either trash fish or live feed in this type of system. This is inefficient in terms of production as a specialised diet would promote higher rates of growth and survival, but that is not possible as of now due to the lack of knowledge. Thus, rainbow trout feed is frequently administered as they share similarities and efficient survival rates have been recorded (feed conversion rates of 1.0–1.5 were registered and high survival rates were also obtained (>80%)).]]> 2021-11-18 06:21:13 UTC https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898791333 Broodstock https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898815806 Perch become sexually mature before they reach market size. Small perch spend energy on development of reproductive organs and spawning rather than on meat production. Thus, to counter this, research to develop both sterile fish and all-female production has been conducted.]]> 2021-11-18 06:39:26 UTC https://padlet.com/200146891/mnnc5f7vuhlsv4ga/wish/1898815806
