This study investigated the effects of the fish meal replacement by dried kitchen waste on growth and carcass composition of tilapia, giant grouper and orange-spotted grouper.
In the first trial, three isonitrogenous (30％ crude protein) and isoenergetic (252 Kcal/100 g) diets were formulated and 0％, 50％, 100％ of fish meal protein was replaced by kitchen waste powder. Fish meal and kitchen waste were used as main dietary protein sources. Each treatment had three replicates and experimental duration was six weeks. Tilapia (1.46 ± 0.03 g) fed 0％ kitchen waste diet had the best weight gain (722.37％), specific growth rate (SGR=5.02% day-1) and food conversion rate (FCR=1.46). However, the weight gain percent of tilapia fed 0％ kitchen waste diet was significantly higher than that of tilapia fed 50％ kitchen waste diet and 100％ kitchen waste. Survival rate of tilapia in 0％ kitchen waste treatment was 67％ and above 90％ for other treatments.
In the second trial, three isonitrogenous (30％ crude protein) and isoenergetic (252 Kcal/100 g) diets were formulated and 0％, 50％, 100％ of fish meal protein was replaced by kitchen waste powder. Fish meal and kitchen waste were used as main dietary protein sources. Each treatment had three replicates and experimental duration was six weeks. Giant grouper (3.81 ± 0.11 g) fed 0％ kitchen waste diet had the best weight gain (801.0％), specific growth rate (SGR=5.24% day-1) and food conversion rate (FCR=1.39) among all treatments. However, the weight gain percent of giant grouper fed 0％ kitchen waste diet was significantly higher compared to those groupers fed 50％ kitchen waste diet and 100％ kitchen waste. Survival rate in all treatments was above 92％.
In the third trial, five isonitrogenous (40％ crude protein), isolipidic (12％ crude lipid) and isoenergetic (328 Kcal/100 g) diets were formulated and 0％, 10％, 20％, 30％, 40％ of fish meal protein were replaced by kitchen waste powder. Fish meal and kitchen waste were used as main dietary protein sources. Each treatment had three replicates and experimental duration was four weeks. Orange-spotted grouper (2.33 ± 0.05 g) fed 0％ kitchen waste diet had weight gain (469.5％), specific growth rate (SGR=5.8% day-1). However, the weight gain percent of orange-spotted grouper fed 0％ kitchen waste diet was no significantly higher compared to those groupers fed 10％ kitchen waste diet and 20％ kitchen waste. Survival rate in all treatments was 100％.
