Dietary protein and lipid requirement of Marble Goby, Oxyeleotris Marmoratus
Two feeding experiments were conducted to investigate the dietary protein and lipid requirement of marble goby, Oxyeleotris marmoratusjuvenile. Three isolipidic (10%) diets were formulated in Experiment I to contain 40, 45 and 50% of dietary protein (as P40, P45 and PSO, respectively) and fed to juv...

| description | Two feeding experiments were conducted to investigate the dietary protein and lipid requirement of marble goby, Oxyeleotris marmoratusjuvenile. Three isolipidic (10%) diets were formulated in Experiment I to contain 40, 45 and 50% of dietary protein (as P40, P45 and PSO, respectively) and fed to juveniles of initial body weight (BW) 1.93 ± O.Olg. In Experiment II, four isonitrogenous (48% protein) diets containing different levels dietary lipid at 10, 14, 18 and 22% (as LlO, L14, L18 and L22, respectively) was fed to groups of juveniles with initial BW: 2.76 ± 0.02g. Experiment duration for Experiment I and II was 15 weeks. In each of the feeding trials, a recirculation culture system was used and water quality was monitored periodically. Before commencing the feeding trials, all juveniles were weaned to formulated feed. During experiments, juveniles were fed to apparent satiation twice times daily. At the end of the feeding trial, some juveniles from each treatment were sacrificed for body indices and whole body proximate analysis. The remaining juveniles in both experiments were used to collect faeces for apparent digestibility test in each respective experiment. The results of Experiment I showed that diet P45 which contained 48.6% protein supported highest growth, final BW, specific growth rate (SGR), protein efficient ratio (PER), nitrogen retention efficiency (NRE), apparent protein and lipid digestibility coefficient; and significant better feed conversion ratio (FCR) (P<0.05) than other treatments. Results of Experiment II showed that LlO that contained 10% of dietary lipid led to highest growth, SGR, final BW, PER; and significant lower hepatosomatic index, viscerosomatic index and intraperitoneal fat (P<0.05) than other treatments. This present study showed that juveniles fed dietary protein and lipid of 48.6% and 9.45% achieved highest growth. The increase of protein or lipid/energy content higher than this level did not supported higher growth. |
