利用虾池排出水养殖菲律宾蛤仔的研究

On culturing clam Ruditapes philippinarum in drainage canal of prawn ponds

本文报道了福建泉州市晋江县金井垦区利用虾池排出水试养匪律宾蛤仔(花蛤)的结果。垦区排水渠道具有丰富的饵料生物和适宜的流水条件,饲养3个月的花蛤个体平均重量从1.5g增至6g。每亩毛产量可达2756kg。体重(W)相对月增长率与体重呈负相关(R_fW=1.028—0.405lnW)。调查结果还表明,这种花蛤养殖方式可大大地降低虾池排出水的有机质含量,从而减轻其邻近内湾的有机质污染压力。

A survey of cultivation of clam Ruditapes philippinarum in drainage cana(?) of prawn ponds was made in Jinjing,Jinjiang, Fujian,during June to October 1990. The result showed that the clam had a high growth rate with a gross production of 2756kg/mu(per mu=666.6m^2) as sufficient food was supplied in the drainage. The body weight (W) and its relative growth rate(R_(?) W) showed a negative correlation. The regression equation was R_fW=1. 028-0. 405 (?)nW. The result also showed that this way of clam aguaculture could bring down the organic pollution from drainage of prawn ponds into the neighbouring sea water.
