对虾、青蟹、江篱混养试验研究

本试验研究改良了池塘水质环境,预防了疾病的发生和避免了虾蟹相残,使以虾为主的虾、蟹、藻混养试验池与对虾单养对照池的对虾成活率大体接近,实现亩均综合产量222.05kg,亩均产值6985.13元,亩均盈利2472.61元,是一种高产、优质、高效的多元化养殖模式。

STUDIES ON THE EXPERIMENTAL POLYCULTURE OF PRAWN, MUD CRAB AND GRACILARIA

Based on the study and the improvement of the environment of water quality in pond, the prevention of the occurrence of disease and the avoidance of the mutual slaughter within prawns and mud crabs in the experiment, the survival rates of the experimental pond for polyculture of prawns, mud crabs and Gracilaria in which prawns play an important role were approximately to that of the contrast pond for monoculture of prawns. The experiment has achieved the synthetical yield of 222. 65 kg/mu with the value of 6985. 13 yuan/ mu, and the profit of 2472. 61 yuan/mu. It shows that the polyculture pattern has the ad-vantages of high output, top quality and high efficiency.
