饲料颜色对星斑川鲽幼鱼摄食影响的研究

Effects of Diet Colors on the Ingestion of Young Starry Flounder(Platichthys stellatus Pallas)

将绿色、黄色、红色和原色4种颜色的相同营养成分与粒径的颗粒饲料投喂星斑川鲽幼鱼,研究饲料颜色对星斑川鲽幼鱼摄食的影响。结果表明:饲料颜色对星斑川鲽幼鱼摄食行为的影响不明显;星斑川鲽幼鱼摄食的每种颜色饲料的颗粒数目以及每种颜色饲料的重占其摄食饲料总重的比例,各组间差异均不显著(P>0.05)。

Pellet feeds with green, yellow, red and original colors respectively, and the same nutrient components and particle size （4.0 mm） were provided for feeding young starry flounders, to study the effects of diet color on the ingestion of the fish. The results showed that there were no obvious effects on the ingestion behaviors of young starry flounders. The particle numbers of all ingested feeds with different colors as well as the proportions of weight of all ingested feeds with different colors to the total weight of feeds ingested were insignificantly different from each other （P≥0.05）.
