A biochemical laboratory manual for species characterization of some tilapiine fishes

This publication is both a manual for the biochemical analysis of several tissues of tilapias and an empirical demonstration of the methods for several species. Given the great and growing importance of tilapia in aquaculture and the importance of knowing the genetic composition of broodstock, the present work pays particular attention to blood-based tests in an effort to determine whether non-destructive sampling of fish tissue is feasible.
