Esta investigación muestra la promesa de mejorar los protocolos de alimentación de camarones en sistemas de biofloc, especialmente en regiones con fluctuaciones significativas de la temperatura del agua.

Certification programs presently are what is a good feed conversion ratio best tool to assure that aquaculture products are responsibly produced. But these programs can be burdened by many superfluous requirements and their simplification by focusing primarily on the major issues would be a great improvement.

The production period for largemouth bass in ponds hampers the economic feasibility of pond culture in the United States. A study demonstrated that bass fingerlings could be raised at high densities in a semi-closed recirculating system without serious mortality, size variability or growth retardation. A growth trial using hatchery-reared grouper was carried out to study the effects of stocking density on feed intake and subsequent growth.

Contrary to common perceptions, fish stocked at the highest density had higher feed intake and body weights. Uneaten or undigested feed and their metabolic byproducts contribute to declines of water quality in aquaculture systems. Accordingly, feed and feeding techniques require continuous review. Reducing overfeeding is an important opportunity for improving feed conversion ratios. Vietnam Organic applied an enzymatic hydrolysis process on shrimp head waste to produce a shrimp soluble extract SSE feed attractant that contains a mixture of free amino acids and peptide.
