Abstract

Feeding efficiency is an important factor that supports the success of lobster grow-out culture. This study aimed to investigate growth of different sex of lobsters after being fed with combination of compound and fresh feed in indoor tanks (experiment-1) and growth of male lobster fed with different co-feeding diets in net floating cages (experiment-2). In experiment-1, five replicates of ten lobsters (191.1 ± 18.1 g) for each different sex (i.e., all males, males and females, and all females) were reared in 2 × 2 × 1 m3 tanks with flow through water system and fed with combination of compound (75%) and fresh feed (25%) for 120 days. In experiment-2, four replicates of 20 all male lobsters (183.6 ± 17.6 g) were reared in 12 net cages of 2 × 2 × 2.5 m3 and were fed with compound feed only, compound feed (75%) and fresh feed (25%), and compound feed (75%) with mussel meat (25%) for 120 days. Experiment-1 showed that growth (quantified as weight gain) of all male lobsters was the highest (59.4 ± 10.0 g). Experiment-2 showed that compound feed combined with fresh feed resulted in higher growth of lobster (0.73 ± 0.17 g) than 100% compound feed. There was no difference in survival rate of lobster among the treatment in both experiments with 94 – 100% in experiment-1 and 75.2 to 85.0% in experiment-2. The mortality of lobster caused by Milky Hemolymph Disease (MHD) in floating cage was found higher than in indoor tanks.

在水槽和浮网笼中饲养的、投喂复合饲料和新鲜饲料的黑龙虾的生长反应

投喂效率是龙虾生长养殖成功的重要因素。本研究旨在调查不同性别的龙虾在室内水箱中混合投喂配合饲料和新鲜饲料后的生长情况（实验-1），以及雄性龙虾在网浮笼中投喂不同配合饲料后的生长情况（实验-2）。在实验-1 中，在 2 × 2 × 1 m3 的流水系统水箱中饲养了 5 个重复，每个重复 10 只不同性别的龙虾（191.1 ± 18.1 g）（即所有雄性、雌雄和所有雌性），并投喂了复合饲料（75%）和新鲜饲料（25%），共 120 天。在实验-2 中，20 只全雄性龙虾（183.6 ± 17.6 克）的四个重复被饲养在 12 个 2 × 2 × 2.5 立方米的网笼中，120 天内分别投喂配合饲料、配合饲料（75%）和新鲜饲料（25%）以及配合饲料（75%）和贻贝肉（25%）。实验-1 显示，所有雄性龙虾的生长量（以增重量化）最高（59.4 ± 10.0 克）。实验-2 显示，配合饲料与新鲜饲料混合投喂，龙虾的生长量（0.73 ± 0.17 克）高于 100%配合饲料。两次实验中不同处理的龙虾存活率没有差异，实验-1 为 94 - 100%，实验-2 为 75.2 - 85.0%。在浮笼中，龙虾因乳状血淋巴病（MHD）造成的死亡率高于室内水槽。
