花尾胡椒鲷人工育苗技术的初步研究

Preliminary Studies on the Fry Rearing Techniques of the Yellow Spotted Grunt, Plectorhinchus cinctus (T.et Schl.)

１９９７、１９９８年４～７月在厦门集美进行了花尾胡椒鲷人工育苗技术的初步研究．选取网箱养殖的成熟亲鱼，采用ＬＲＨ－Ａ２、ＨＣＧ和ＤＯＭ进行人工催产并进行人工授精；以６０ｍ３的室内水泥池作育苗池，将受精卵置于育苗池中孵化，并进行鱼苗培育，后期培育移到海上网箱进行．两年共育出平均全长２５．０ｍｍ以上的花尾胡椒鲷苗种３２．１万尾，育苗成活率达３４．２％～５１．０％．

In this paper,the preliminary results of studies on the artificial propagation and fry rearing of the yellow spotted grunt, Plectorhinchus cinctus during April to July in 1997 and 1998 were reported.The spawners were cultured in the cages on the sea,and were injected with LRH-A 2,HCG and DOM.The fertilized eggs were obtained by artificial fertilization.The fertilized eggs were hatching in the rearing tank indoor,and the larvae were rearing in the tank too.The larvae were fed with eggs and larvae of oysters,rotifers,artemia nauplii,copepods,cladoceras and fish meat.During two years,321 thousands young fish attained the total length more than 25.0 mm on the average,with survival rate of 34.2%～51.0 %.
