Effect of Larger Fısh and Size Grading on Growth and Biomass Gainn Nile Tilapia (Oreochromis niloticus) in Cage Conditions

In this study the effects of larger fish and size grading on growth of Nile tilapia were investigated. Fish close to mean population size (10.24l3.09 g) were raised either in presence (20% of the population), or absence of larger fish (39.95l2.12 g) for 60 days. At the end of the study growth was c...
