渤海湾魁蚶吊笼与底播增殖实验研究
Experiment research of the cage culture and bottom sowing culture of Scapharca broughtonii in Bohai Gulf
摘要
Abstract
The purpose of this experiment was to investigate the impact of different cage inputting specifications on the growth and survival rates of Scapharca broughtonii. The study also compared the differences of cage culture and bottom sowing culture. The results indicated that the best cage inputting specification was 1.5cm. The cage inputting specification should be greater than 3.5cm during winter, but the best choice during summer was between 2.5cm and 3cm. The optimum density was 1000 ind/layer during the first summer and 500 ind/layer during the first winter. The optimal density during the second winter and summer period were 200 ind/layer and 100 ind/layer, re-spectively. According to the results of farming in hoisting cages, there could be greater survival rates if one begins bottom sowing culture when the length of S.broughtonii was between 3cm and 4cm.Therefore,these results dem-onstrated that relay breeding of S.broughtonii in the hoisting cage and the bottom of the sea could be an effective farming mode that could raise the efficiency of farming S.broughtonii.关键词
