摘要
2013年8月至2014年2月,对莆田后海垦区菲律宾蛤仔(Ruditapes philippinarum)反季节高效生态养殖池叶绿素a、浮游植物初级生产量、蛤仔死亡率等进行了测定,采用Parsons T R和Takahashi M营养动态模型和Tait沿岸海域能流分析模型对2个菲律宾蛤仔养殖池的养殖容量进行估算,扣除20%的日排水量导致的初级生产量损失,2种估算模型得到的养殖容量经校正后,分别为池1为5.52t、7.1t,平均为6.31t;池2为3.60t、4.62t,平均为4.11t。两个花蛤养殖池的实际产量分别为估算养殖容量的59.43%、97.32%,根据模型估算的适宜底播密度分别为池1为0.61kg/m2,池2为0.40kg/m~2,鉴于根据估算养殖容量计算的菲律宾蛤仔的适宜的养殖密度大于实际养殖密度,因此,有一定的潜能可以适当增加花蛤的投放数量。
From August 2013 to January 2014, the chlorophyll-a, primary productivity of phytoplankton, clams mortality rate were determined. The carrying capacity of the two Manila clam ponds were estimated by Parsons TR-Takahashi M Ecological Trophodynamics model [P =(BEn)×k] and Tait coastal energy flowing analysis model{B = [(0.1×C)/Q]×k}. Taking into account of unused the primary productivity due to 20% the pond daily effluent, the corrected results of two models above were 5.52 t and 7.10 t for pond 1, with an average of 6.31t; 3.60 t and 4.62 t for pond 2,with an average of 4.11 t. The actual yields of the two ponds accounted for 59.43% and 97.32% of the estimated capacities respectively. Two ponds of clam mortality rates were 23.43%, 22.5%,respectively. The carrying capacity of pond 1 was significantly larger than that of pond 2,while the carrying capacity of pond 2 was close to the actual yield, The estimated suitable breeding densities of Manila clam for pond 1 and for pond 2 were 0.61kg/m2 and 0.40kg/m2, respectively.As the actual breeding densities of two ponds are 0.19kg/m2 for each pond. A certain potential to increase the number of breeding clam appropriately exists. The estimated suitable breeding densities of Manila clam calculated from the carrying capacity was larger than the actual breeding densities.
