充分利用水库资源及网箱优势,结合斑鳜繁育生物学特性,在水库网箱上成功批量繁育斑鳜鱼苗,为斑鳜人工繁育开辟一条新途径。2012年5月~2013年7月在辽宁省宽甸县景波水产品养殖场共进行了6批次繁育试验,共计催产亲鱼146组,平均催产率84%,获卵320万粒,平均受精率65%,平均孵化率80%,获水花鱼苗180万尾,利用水库网箱孵化鲤鱼苗配套提供饵料,繁殖了鲤水花11亿尾,共培育斑鳜夏花鱼苗40万尾(平均全长3.1cm),平均2750尾鲤鱼苗培育一尾斑鳜苗,培育前3d斑鳜全长日增长0.54mm,3d后全长日增长约1mm。水温19℃~22℃,显微摄影观察斑鳜胚胎发育时序和特点,受精卵140h7min破膜,胚胎发育划分为6个阶段25时期,提出在斑鳜产卵后配套饵料鱼亲鱼注射催产时间公式:t=t1-t2-t3;(t1:斑鳜胚胎发育时间;t2:饵料鱼胚胎发育时间;t3:饵料鱼亲鱼效应时间)。

英文摘要：

Making full use of the advantages of reservoir resources and cage culture and combining with the biological characteristics of S. scherzeri, the propagation of fry succeeded in batches based on the reservior cage culture, which could develop a new approach for the artificial propagation of S. scherzeri. Six breeding trials were carried out from May 2012 to July 2013 in Jing-bo fishery farm of Kuandian Manchu Autonomous county in Liaoning Province. Totally, 146 pairs of broodstock were induced to spawn by hormone in-jection, with the average spawning success of 84%. 3.2 million eggs were obtained with the average fertilization rate of 65%, and 1.8 million fry were obtained with average hatching rate of 80%. 400 thousands of Juveniles (average total length of 3.1 cm) were ob-tained and fed with common carp fry(1.1 billion) hatched in reservoir cages, with one S. scherzeri fry fed with 2750 common carp fry, In the first 3 days, the growth rate of total length was about 0.54 mm/day, then the rate was 0.95~1.25 mm/day. At the temperature be-tween 19℃and 22℃, photomicrography was applied to observe the embryonic development time and characteristics of S. scherzeri. The eggs began to hatch out at 140h7min after insemination, all the process of embryonic development could be divided into six phas-es and 25 periods. The injection time formula for the bait fish broodstock should be induced as follows: t=t1-t2-t3 (t1:the time of fetation of S. scherzeri;t2:the time of fetation of forage fish;t3:the time from hormone injection to laying eggs of forage fish).
