通过性激素处理,使雄鲇鱼转变为雌鲇鱼,其生长速度能加快两倍以上,该技术已由韩国在世界上率先开发成功。韩国釜山水产大学养殖学科金东秀博士研究小组,从1987年开始,经过5年多的研究,开发了通过性转换的鲇鱼养殖法。该方法是25℃的水槽中把刚孵化的雄鲇鱼在0.4ppm雌激素(雌甾二醇)溶液中生长10天,其中97.8％的雄性鲇鱼变成了雌性。用已转性的雌鲇鱼和正常的雄鲇鱼交配,就可产生三倍体雌鲇鱼,在同样条件下,生长8个月的三倍体雌鲇鱼要比雄鲇
By sex hormone treatment, the male catfish into pomfret, its growth rate can be accelerated more than twice, the technology has been South Korea in the world take the lead in the development of success. Kim Dong-soo, Ph.D., Division of Aquaculture, Busan Fisheries University, Korea. Since its establishment in 1987, more than five years of research have led to the development of a mandarin fish culture through sex conversion. The method was to grow newly hatched mandarin fish in a 25 ° C water bath for 10 days in a 0.4 ppm estrogen (estradiol) solution, of which 97.8% of males were female. Trichotoma pomfret can be produced by mating female mullet and normal male mullet, and triploid pomfret that grows for 8 months under the same conditions
