Both published and original research on the
requirements of cultured carnivorous and omnivorous
marine fish is reviewed. Typical species grow best on
high-protein, low-carbohydrate diets, well fortified
with vitamins and minerals, and containing sufficient
essential fatty acids. Protein and fat requirements
(dry basis) for most marine species studied are in the
ranges 50-60% and 10-20%. Typical upper limits are
10-20% carbohydrate, 4% fibre, 10-25% ash, and
10% moisture. Attractive substances can be added to
feeds to increase ingestion, growth stimulators to
increase growth, and pigments to enhance colour. A
minimum dietary content of 2% n3HUFA (long-chain
highly-unsaturated fatty acids), including at least
1.0% each of eicosapentaenoic and docosahexanoic
acids for young fish and 0.7% of each for older fish
seems to be a reasonable safeguard against
essential fatty acid deficiency. Antioxidants should be
included to protect against oxidative rancidity.
Suggestions for dietary constraints and basic
formulas for practical starter and grower feeds are
provided. Florida Atlantic University. Harbor Branch Oceanographic Institute contribution 884 This manuscript is an author version with the final publication available and may be cited as: Tucker, J.
