What is feed conversion ratio (FCR) in catfish?

Feed Conversion Ratio (FCR) in catfish farming is the percentage quantity of feed consumed by a given number of catfishes that is converted into body weight (flesh and bone) for human consumption. FCR is the basis of all feed formulations because feeds are compounded to support profitable and healthy growth of catfishes.

What is Feed Conversion Ratio or FCR? Feed conversion ratio or FCR is a measure of an animal’s efficiency to convert feed into increased body mass. It indicates how efficient an animal is to convert feed mass to the desired output.

What is the feed conversion ratio of farmed catfish?

And this farmed catfish had a feed conversion ratio of about 1. FCR in poultry is calculated by dividing the total input of the feed from the weight gained by animals or by the number of produced eggs. To be more precise, the input is divided by the output.
