摘要
为探究七彩神仙鱼工厂化养殖技术,在水温28~30℃的室内水泥池中开展了七彩神仙鱼养殖试验,放养的幼鱼全长1.5~2.0 cm,放养密度为200尾/m^(3)。经过约120 d养殖,试验鱼全长达9.0~10.0 cm,达到商品规格。结果表明,七彩神仙鱼每年可养殖3茬,平均成活率达87.8%,平均单位水体产出达175.6尾/m^(3)。工厂化养殖系统可全年生产运转,水质相对稳定,单位水体养殖密度较高。
In order to explore the industrial culture technology of discus fish(Symphysodon aequifasciata),the culture experiment of S.aequifasciata was carried out in the indoor cement pool with 28-30℃of water temperature,1.5-2.0 cm of initial body length and 200 tail/m^(3) of stocking density.The average body length of test fish reached to commercial specification of 9.0-10.0 cm after 120 days of rearing.The results showed that S.aequifasciata could be cultured for three stubbles per year,with an average survival rate of 87.8%,and an average output of 175.6 tail/m^(3) per unit of water.The factory aquaculture can be produced and operated all year round with relatively stable water quality and high aquaculture density.
