摘要

The present study aims to evaluate the effects of several types of larval feed on seed production of the oriental river prawn Macrobrachium nipponense and water quality in extensive rearing systems. Healthy M. nipponense were distributed into fifteen 15-m(2) pond outdoors, and each pond was stocked with 90 prawns including 41 egg-bearing (berried) female prawns, 37 not bearing female prawns, and 12 male prawns for larval production. The experimental design was completely randomized, with four diet groups (diet A: soybean homogenate, diet B: yeast, diet C: yeast + fermented soybean meal, and diet D: yeast + fermented soybean meal + microparticulate diet) and one no feeding control and three replications. There are equal levels of the total protein content in diets A-D. Higher larvae and postlarvae number was obtained for diet C and diet D. Furthermore, the increase of M. nipponense larvae and postlarvae in diets B-D can result in the decrease of zooplankton and increase of phytoplankton in the pond during some periods, simultaneously improving the water quality. The Spearman correlation coefficient (r(M,N)) between the amounts of larvae and postlarvae of M. nipponense per pond and zooplankton per pond during the entire experiment period was - 0.56. The highest juvenile M. nipponense production was obtained in the diet D group (3140.00 +/- 461.63), which was slightly higher than that in the diet C group (2940.33 +/- 382.60). The juvenile M. nipponense production in diet B (2303.00 +/- 449.23) was also significantly higher compared to diet A (1106.33 +/- 176.64) and the control group (1039.67 +/- 212.85). There were no significant differences in the amounts of juvenile M. nipponense between the control and diet A groups, which indicated that the soybean homogenate could not increase the amount of M. nipponense juveniles. Our results clearly showed that diet D significantly raised per unit yield of prawn seed comparing with no feeding and other diet group in extensive rearing systems and that the cost of producing prawn seed with diet D is low, which provide an important foundation for the expansion of oriental river prawn culture.

Nipponense分布到户外十五（2）棵池塘，每位池塘都有90虾，包括41名蛋（Berried）女性虾，37名没有患有雌性虾，12名雄性虾类，用于幼虫生产。实验设计完全随机化，四个饮食群（饮食A：大豆匀浆，饮食B：酵母，饮食C：酵母+发酵豆粕，饮食D：酵母+发酵大豆膳食+微粒饮食）和一个无饲料饮食和三次复制。饮食A-D中的总蛋白质含量等平等。获得较高的幼虫和后的饮食和饮食D.此外，饮食中的M. nipponense幼虫和后的饮食BD的增加可能导致浮游植物减少，在某个时期，池塘中的浮游植物的增加，同时改善水质量。在整个实验期间每池塘和Zooplankton的M. nipponense的幼虫和M. nippoonense之间的幼虫和后r（m，n）之间的刺激族相关系数（r（m，n）为-0.56。在饮食D组（3140.00 +/- 461.63）中获得了最高的青少年M. nipponense生产，其略高于饮食C组（2940.33 +/- 382.60）。与饮食A（1106.33 +/- 176.64）和对照组相比，饮食B（2303.00 +/- 449.23）和对照组（1039.67 +/- 212.85）也显着提高了饮食B（2303.00 +/- 449.23）。对照和饮食之间的青少年母细胞的数量没有显着差异，这表明大豆匀浆不能增加M. nipponense青少年的量。我们的结果清楚地表明，饮食D每单位产量大虾种子比较广泛的饲养系统中没有饲养和其他饮食组，饮食D饮食D的成本低，为扩建提供了重要的基础东方河大虾文化。
