研究在循环水养殖模式下,不同养殖密度对青石斑鱼生长的影响。在试验中选用20、40、60kg/m3这三个密度组,每组循环水养殖设三个重复循环,在一个闭合的循环水养殖系统中,养殖青石斑鱼质量为112.3±4.9g,对其进行养殖60d。通过本次试验,表明过高的养殖密度不利于青石斑鱼生长,但从经济角度来说,这三组养殖密度中,40kg/m3是较为适宜的养殖密度。
The effects of different culture densities on the growth of green grouper under recirculating aquaculture mode were studied. In the experiment, three densities of 20, 40, and 60 kg / m3 were selected, and each cycle of aquaculture was re-circulated for three times. The aquaculture quality of the grouper was 112.3 ± 4.9g in a closed recirculating aquaculture system. Its breeding 60d. Through this experiment, it shows that too high density of culture is not conducive to the growth of green grouper, but from an economic point of view, the three groups of breeding density, 40kg / m3 is more appropriate breeding density.
