| 摘 要： | １９９４年１２月放养平均壳高３．９ｃｍ，平均体重１０ｇ的脉红螺苗４万个，经过１３个月海上筏式养殖，平均壳高达７．４３ｃｍ，平均体重８３．５ｇ，亩产达到２７２０ｋｇ，总成活率９４．４％，亩纯收入３５４５０．９０元，约是扇贝养殖的４倍。放养密度以１０个／层产量最高，贻贝为最佳饵料品种。应加强４￣１０月脉红螺快速生长期的管理，专家鉴定认为，本研究居国内领先水平。

| Abstract: | In December,1994,forty thousand larvae of Rapana venosa with the average shell height of 3.9 cm and body weight of 10 g were cultured with raft in the Laizhou Bay.After cultured 13 months in the sea,the Rapana venosa were growing up to the adult with the average shell height of 7.43 cm and the average body weight of 83.5 g.The per mu yield reached 2720 kg and the total survival rate was 94.9%.The net income was 35450.90 yuan,around four times than that of the cultured scallops.The result showed that the best diet is mussel;the highest yield will be obtained with the released density of ten ind.per layer in the culturing cage;the management ought to strenthen during Apr.to Oct.(rapid growing period).The result,appraised by experts,is in the lead at home. |
