半滑舌鳎室内水泥池和池塘养殖技术的初步研究

Studies on industrialized culture technology for tongue sole (Cynoglossus semilaevis Günther)

利用现有的工厂化养殖设施养成半滑舌鳎,以不投喂人工饲料的室外池塘养殖作为对照,评估一种自制沉性配合饲料的养殖效果。结果表明,在9个月的养殖期内,初始平均体重为37.2g的半滑舌鳎在投喂配合饲料的工厂化养殖条件下,平均体重达到566.4g,成活率95.5%,而室外池塘中不投饵的自然条件下养殖,平均体重仅为464.6g。

Tongue sole（Cynoglossus semilaevis Gtinther） were reared in indoor tanks with the outdoor earthern pond culture as control. An artificial sinking diet were used in indoor tanks culture to evaluate the rearing effect, while outdoor pond culture use of natural food. The initial body weight of experimental fish averaged 37. 2 g. Results showed that after 9 months culture,fish cultured in indoor tanks and fed with artificial feed attained a body weight averaged 566.4 g with a survival rate 95. 5 %, while their counterparts in outdoor pond only grew to 464. 6 g.
