5种滤食性贝类对牙鲆的粪便、残饵及网箱养殖区沉降物的摄食行为
Feeding behavior of 5 species filter-feeding bivalves on Paralichthys olivaceus feed, fecal and sediment particulates in cage farming area
摘要
Abstract
5 species bivalves' feeding behavior on different food,including flounder (Paralichthys olivaceus) faeces,residul feed and deposition was studied so as to discuss the potential IMTA based on filterfeeding bivalves.Results showed the 5 species bivalves could feed on fish faeces,residul feed and deposition.However,different species showed different feeding behaviors.Ingestion rates of oyster,clam and scallop were significantly higher than the other 2 species (two-way ANOVA,P < 0.01),and absorption efficiency(AE) and absorption rate(AR)of the 5 species bivalves were not significantly different.Diet had significant influence on the feeding behavior.With particle organic matter (POM) increasing,AE increased.There were significantly linear relationship between AR and POM.TPM threshold for pseudo-feces production of oyster and scallop and was 26.24,21.64,27.00 mg/L,respectively,and the 5 species bivalves could regulate food intake by pseudo-feces production.The shellfish + fish IMTA mode,clam Ruditapes philippinarum,oyster Crassostrea gigas and scallop Chlamys farreri are relatively good candidate species.关键词
