What are Feed Conversion Rates?
Feed Conversion Rates (FCR) is the relationship between feed given to the animal and the weight gain of the animal.
Nearly all aquaculture producers use feed conversion ratios (FCRs) as an index of feed use efficiency. FCR is determined by dividing the total feed use in a production unit or entire aquaculture facility by the net production of the culture species. Feed Efficiency Indicators for Responsible Aquaculture. Claude E. Boyd, Ph. D.
FCRs vary with several factors, including species, feed type and quality, production system, feeding technique, and water quality conditions. Warmwater fish and shrimp farms typically achieve FCR values of 1.5-2.5, and for general purposes, FCR often is assumed to be 2.0. Feed Efficiency Indicators for Responsible Aquaculture. Claude E. Boyd, Ph. D.
Improve Feed Conversion Rates
Feed is one of the largest costs to an aquaculture farm. Improved feed conversion means less food to produce more fish and shrimp. Uneaten food is consumed by beneficial bacteria that are then eaten by fish. Your feedings become more efficient and more feed is converted to flesh, saving you money. Improved FCR means more profit.
Probiotics improves feed conversion rates through multiple mechanisms that increase metabolic function and improve nutrient digestion.
Probiotics also improve water quality. Better water quality allows fish and shrimp to use energy to add weight rather than wasting energy fighting disease and poor water quality.
Reducing FCR at aquaculture production facilities lowers feed costs and provides environmental benefits. There is less waste per unit of production, and protein and fishmeal are conserved. Even greater benefits can be achieved if percentages of protein and fishmeal can be lessened without lowering feed quality and increasing FCR. Feed Efficiency Indicators for Responsible Aquaculture.

As seen in the graphic to the right, Keeton Probiotics have successfully improved FCR from 1.6:1 to 1.2:1 in cage culture raised Cobia.
Improving FCR on an aquaculture farm means more profit and reduced costs.
FeedTreat™ was developed to bring the benefits of closed systems to cage culture. It is applied to feed and given directly to the animal.
PondToss™ combines the best probiotic and water conditioning bacteria in one formula for aquaculture fish farming. It produces small peptides that have a probiotic effect on fish, improving survival.
ShrimpShield™ creates improved water quality beneficial to health and growth for shrimp farming. ShrimpShield™ produces small peptides that have a probiotic effect on shellfish, improving survival.
