黄海北部虾夷扇贝吊耳养殖技术研究

2010年进行了虾夷扇贝吊耳养殖试验研究。吊耳养殖分为一针四贝及一针二贝2种模式,经过6个月的对比试验,结果显示,与笼养方式相比,吊耳养殖扇贝的壳高增长率、单贝质量、贝柱质量、台产量、台产值等指标具有较大优势,存活率、肥满度、出丁率等指标互有优劣。在吊耳养殖模式下,虾夷扇贝壳高的生长优势明显,其中一针四贝模式的生长优势最大。本试验中吊耳养殖扇贝的总体生长情况优于传统的笼养方式;综合对比2种吊耳养殖模式,一针四贝模式的养殖效果好于一针二贝模式。

Hinge-hanging Culture of Japanese Scallop Patinopecten yessoensis in North Yellow Sea

The 6 month experiment of hinge-hanging culture,including four or two scallops per needle,of Japanese scallop Patinopecten yessoensis was conducted in three waters in north Yellow Sea in 2010.The result showed that there were higher incrementin shell height,body weight,adductor muscle weight,and yield and valueper raft in one growing season in the hinge-hanging culture while there were lower survival,condition factor,and adductor percentage in the hinge-hanging culture than those in th conventional culture method.The maximal shell height increment was observed in the hinge-hanging culture with four scallops per needle in which the value was increased by 900～2800 yuan RMB per raft,and economic benefits by 7800～26800 yuan RMB,though the production cost was increased by 1200 yuan RMB.
