黑鲷(Sparus macrocephalus)属鲈形目,鲷科,俗称黑加吉、铜盆鱼等,是一种自然分布于我国沿海的习见经济鱼类。北自山东,南至两广及海南都把它作为网箱养殖的重要对象。近年来,随着网箱养殖鱼类品种结构的调整,黑鲷养殖业呈上升趋势,养殖苗种需求量不断增加。宁波海湾水产苗种繁育中心于2001、2002年分别进行了黑鲷规模化育苗及海区网箱大规格苗种培育试验,以期为浙江省的黑鲷海水网箱养殖业提供批量的优质种苗。两年来,共培育出5～8cm的大规格苗种2.35×10~6尾,海区网箱培育平均成活率达89％。现将黑鲷网箱大规格苗种培育技术要点总结如下,以供参考。
Black sea bream (Sparus macrocephalus) is a perciformes, seabream Branch, commonly known as black Jiaji, Brackish fish, is a natural distribution in our coastal economic fish. North from Shandong, south of Guangdong and Guangxi and Hainan as an important object of cage culture. In recent years, with the adjustment of the structure of cage cultured fish species, black seabream breeding industry is on the rise, increasing demand for breeding seedlings. In 2001 and 2002, Ningbo Bay Aquatic Breeding and Breeding Center respectively carried out large-scale breeding of black seabream and large-scale seedling cultivation of cages in the sea area, in order to provide batch and high-quality seedlings for sea cucumber aquaculture in Zhejiang Province. In the past two years, a total of 2.35 × 10 ~ 6 large-sized seedlings of 5 ~ 8cm were cultivated. The average survival rate of cages cultivation in the sea area reached 89%. Black snapper cage is now a large-scale seed cultivation technology summarized as follows, for reference.
