摘要
河口捕获平均全长２．５ｃｍ的天然花鲈苗种，分二阶段进行培育。第一阶段是流水淡化驯养：包括淡化、暂养和驯饵；第二阶段是分级培育，每隔４～６ｄ分筛分级一次，直至４～６ｃｍ的鱼种。试验总成活率是５５％。
This paper deals with a method of domestication and graded-cultivation of Japanesesea-bass larvae, 2. 5cm in average total body length, caught from different estuary. With thismethod. the fry reared in concrete tanks obtains good quality and survival rate.This experimentwas divided into two rearing stages: the first stage was domesticating:dilution, temporary cultuvation and domesticating feeding habits. Dilution was achieved by adding flowing fresh water intothe tanks, and the fry was first fed with living brine shrimp, cladocera and copepoda mixed withmashed-fish. Mashed-fish food was gradually increased in proportion until the fry was completely fed on mashed-fish in 4-5 days; the second stage was graded-cultivation. When thefry grew up, it was screened with special fish sieves in every 4-6 days so as to decrease the density of each tank, then the same size of fry screened was put into corresponding tanks in wnichthey could grow well and have little opportunity to massacre each other. The total fry survivalrate of this experiment was 55 %.and the effect was significant.
