Gastric evacuation rate of black sea bream(Sparus macrocephalus)

Abstract

Abstract: The gastric evacuation rate of black sea bream(Sparus macrocephalus)weighing 20～40g was determined at 18℃ in laboratory.Three mathematical models were applied to simulate it.The result indicated that all of these three kinds of models fitted to the experiment data,while statistical analysis showed that the linear model was the best,whether the remained food in stomach was expressed by wet weight or dry weight.When the remained food in stomach was expressed by wet weight,the model was Y=1.14-0.06t(r²=0.82,p< 0.001),and by dry weight,it wasY=1.36-0.07t(r²=0 62,p<0.001).The gastric evacuation rate of black sea bream was 6～7% of consumed food per hour at 18℃.

Key words: Sparus macrocephalus, Gastric evacuation rate, Mathematical model
