Breeding value estimation for harvest weight in a Nile tilapia (Oreochromis niloticus L., 1758) population using BLUP
Abstract :
In this study, breeding values in a Nile Tilapia (Oreochromis niloticus) population for harvest weight was estimated according to weight, age and sex data using Best Linear Unbiased Prediction (BLUP) method. Mean estimated breeding value (EBV) for harvest weight in this unselected tilapia population was found 0.03. Mean EBV of male fish (2.908) for harvest weight was found higher than the mean EBV of females (-2.740) and relation between sex and estimated breeding values of harvest weight was found significant according to a t test. The BLUP method which gives opportunity of the most reliable estimations for all traits of an individual in selecting broodstock was used.
