Effect of replacing fish meal in the fish diet by zooplankton meal on growth performance of Dicentrarchus labrax (Linnaeus, 1758)
This study aimed to evaluate the effect of replacing fish meal in the fish diet by zooplankton meal on the growth performance of European sea bass, Dicentrarchus labrax. A total of 900 fingerlings of the D. labrax were collected from fish hatchery Kilo 21, Alexandria and transported to the fish rearing unit in El-Max Research Station, National Institute of Oceanography and Fishers (NIOF), Alexandria, Egypt. After two weeks for acclimation, the fish were divided into 5 groups, 3 replicates for each group (60 fish in one cubic meter of Haba for each replicate). The five experimental diets were: G1: commercial diet (control group); G2, G3, G4, and G5 fish meal in this commercial diet was replaced by zooplankton meal as 25%, 50%, 75% and 100%, respectively.
The highest values of growth performance parameters and PER & FER of D. labrax were recorded in G5, while the lowest values were recorded in the control group. The best average of FCR (1.75±0.02) was recorded for G5 and its bad average (2.18±0.18) was recorded in G1. The present study concluded that zooplankton positively affected growth performance parameters and enhanced feed utilization of sea bass.
