Abstract

The availability of cheap and high nutritional value artificial feed is a prerequisite for the sustainability of lobster cultivation. In this study, the lobster feed formula was made based on chicken egg hatching waste and maggot flour. The purpose of this study was to determine the performance of scalloped spiny lobsters with artificial feed treatment P1 (70% fish meal + 0% hatching waste), P2 treatment (50% fishmeal + 20% hatching waste), P3 treatment (30% fishmeal + 40% hatching waste), and P4 treatment (10% fishmeal + 60% hatchery waste). This study used lobster seedlings with a size of 1.5 - 3.5 cm which were kept for 60 days. Lobster performance is measured based on body weight, body length, growth rate, feed conversion, molting and lobster dilution rate. The data were analyzed descriptively by presenting mean, standard deviation, and statistical analysis using Duncan's advanced test. The results of the lobster performance study based on absolute length and weight in the P1 treatment were obtained 1.22±0.05 and 1.03±0.21; on P2 treatment obtained 1.31±0.16 and 1.16±0.09; P3 treatment obtained 1.37±0.37 and 1.47±0.13; and P4 treatment obtained 0.82±0.18 and 0.9±0.22. The calculation of the specific growth rate in the P1 treatment was obtained 0.56±0.09, the P2 treatment was obtained 0.69±0.21, the P3 treatment was obtained 0.73±0.16, and the P4 treatment was obtained 0.56±0.24. The ratio of feed conversion and lobster dilution shows a tendency to decrease as the concentration of chicken hatching waste increases. The growth performance of scalloped spiny lobsters fed with chicken egg hatching waste-based feed is quite good up to a concentration of 40% and if more than that will reduce the growth performance of lobsters.

蛋渣人工饲料对栉孔龙虾生长性能的影响
廉价和高营养价值的人工饲料是龙虾养殖可持续发展的先决条件。本试验以鸡蛋孵化废和蛆粉为原料,配制了龙虾饲料配方。本试验旨在研究人工饲料处理P1(70%鱼粉+ 0%孵化废物)、P2(50%鱼粉+ 20%孵化废物)、P3(30%鱼粉+ 40%孵化废物)和P4(10%鱼粉+ 60%孵化废物)对扇贝螯虾生产性能的影响。本研究选用1.5 ~ 3.5 cm的龙虾苗,保存60 d。龙虾的生产性能是根据体重、体长、生长率、饲料转化率、换羽率和龙虾稀释率来衡量的。采用Duncan’s高级检验,采用均数、标准差和统计分析对数据进行描述性分析。P1处理下龙虾的绝对长度和绝对重量分别为1.22±0.05和1.03±0.21;P2组分别为1.31±0.16和1.16±0.09;P3组分别为1.37±0.37和1.47±0.13;P4组分别为0.82±0.18和0.9±0.22。计算P1处理的特定生长率为0.56±0.09,P2处理的特定生长率为0.69±0.21,P3处理的特定生长率为0.73±0.16,P4处理的特定生长率为0.56±0.24。随着鸡孵化废物浓度的增加,饲料转化率和龙虾稀释率呈下降趋势。以鸡蛋孵化废物为基础的饲料饲喂的扇贝龙虾的生长性能在40%的浓度下是很好的,超过40%会降低龙虾的生长性能。
