For trout, stocking rates of 30 to 50 kg/m 3 are normal at the end of a rearing cycle, while for marine species, such as sea bass and sea bream, the achievable load is lower, between 15 and 20 kg/m 3. The total volume required for a raceway is calculated by dividing the total amount of fish in kg by the desired stocking rate in kg per m 3. [17]
On a dry-dry basis, 2–4 kg of wild-caught fish are needed to produce 1 kg of salmon. [23] The ratio may be reduced if non-fish sources are added. [20] Wild salmon require about 10 kg of forage fish to produce 1 kg of salmon, as part of the normal trophic level energy transfer. The difference between the two numbers is related to farmed salmon ...
Large aquaculture facilities (i.e. those producing 20,000 pounds (9,100 kg) per year) which discharge wastewater are required to obtain permits pursuant to the Clean Water Act. [21] Facilities that produce at least 100,000 pounds (45,000 kg) of fish, molluscs or crustaceans a year are subject to specific national discharge standards. [22]
These higher protein-level requirements are a consequence of the higher feed efficiency of aquatic animals (higher feed conversion ratio [FCR], that is, kg of feed per kg of animal produced). Fish such as salmon have an FCR around 1.1 kg of feed per kg of salmon [11] whereas chickens are in the 2.5 kg of feed per kg of chicken range. Fish do ...

A typical female produces about 2,000 eggs per kg (900 eggs per lb) of body weight at spawning. Brown trout can live 20 years, but as with the Atlantic salmon, a high proportion of males die after spawning, and probably fewer than 20% of anadromous female kelts recover from spawning [citation needed].
