文摘

This is the first study to estimate FE of individual fish reared in group for an extended and continuous period of time. Provides the first accurate estimate of the phenotypic correlation between RFI and FCR in fish Feed intake and feed efficiency traits between individual tilapias are highly variable Phenotypic differences of feed conversion ratio between males and females are significant.
