摘要

摘要海参因其营养价值和药用价值，在国际市场上需求量很大。本研究分析了两种饲料饲喂不同比例的糙斑海参幼参的生长性能。试验采用市售海参饲料(饲料- a)和配制饲料(饲料- b)。饲喂2%饲料- a的动物表现出负增长。饲料a和饲料b添加量分别为8%时，生长最快。饲料a处理组的生长性能在不同比例饲粮之间有显著差异(P < 0.05)，而饲料b处理组的差异不显著。饲料b处理过的海参比饲料a处理过的海参生长速度更快。饲养池的水质参数和土壤的缺氧条件没有因饲料比例的增加而发生变化。综上所述，饲料比例是影响海参生长的重要因素。

Effects of diet quantity on growth performance of juvenile sea cucumbers Holothuria scabra

Abstract Sea cucumbers are in high demand in the world market due to their nutritional and medicinal values. In this study, the growth performance of juvenile sea cucumbers Holothuria scabra fed with different proportions of two feeds was analyzed. Commercially available sea cucumber feed (feed-A) and formulated feed (feed-B) were used for the experiments. Animals fed with 2% feed-A showed a negative growth rate. Maximum growth was observed in animals fed with 8% feed-A and feed-B. While feed-A treated groups showed significant variation (P < 0.05) in growth performance between different percentages of diets, feed-B treated animals showed no such variation. Feed-B treated animals showed higher growth rates compared to feed-A treated sea cucumbers. Water quality parameters and anoxic conditions of the soil in culture tanks did not change due to the higher percentage of feeds. In conclusion, this study showed that diet percentage is an important factor for the optimum growth of sea cucumbers.
