    1. Atlantic salmon has a bigger yolk sac than the glithead seabream. The bigger yolk sac of the atlantic salmon will allow it to last for 3 weeks without any feed while the glithead seabream is able to last without feed for only 3 days.
    2. Atlantic Salmon larvae has a larger mouth than the glithead sea bream which means the atlantic salmon larvae can be fed on larger feed unlike the glithead seabream

The most appropriate time to start feeding small-size particles in the form of granules or crumbles is when this reserve is completely absorbed. At this stage, they are switched to starter feeds and fed frequently throughout daylight hours or during a set photoperiod regime. 
    Swim-up fry are fed in slight excess so that slow-sinking feed is visible for capture. However, an excessive amount of feed particles suspended in the water column may affect gill respiration and predispose fry to bacterial infections. The frequency of feeding is dependent on the water temperature and body size. Generally, feeding is reduced from 8–12 times or more daily to 3–4 times a day for fingerlings and parr. Feed consumption is readily reduced by poor water quality, low water exchange, high density of fry and physiological state of fish.

    The egg yolk is quite large hence it is able to sustain the larvae until it is big enough to eat formulated feed.  The larvae do not need to waste energy for trying to find feed but rather use the energy for growth and development.
