发酵豆粕与发酵杂粕代替部分鱼粉饲养凡纳滨对虾的比较

Raising experiment of Litopenaeus vannamei by fermented soybean meal and fermented mixed meal to substitute partial fish meal

利用发酵豆粕和发酵杂粕来代替鱼粉进行凡纳滨对虾的养殖试验.在发酵豆粕等氮替代10%鱼粉的对虾养殖试验中,发酵豆粕组与高鱼粉含量的对照组相比,凡纳滨对虾的生长非常接近,无显著性差异.在养殖结束时,凡纳滨对虾体质量与体长的比值要高于对照组.在发酵杂粕等氮替代10%鱼粉的对虾养殖试验中,发酵杂粕组与对照组及豆粕组相比,凡纳滨对虾的生长均无显著性差异.实验结果表明,发酵豆粕和发酵杂粕能部分替代鱼粉用于凡纳滨对虾的养殖.

The fermented soybean meal and fermented mixed meal were used to replace fish meal in practical diets for raising experiment of Litopenaeus vannamei. In the experiment of raising Litopenaeus vannamei which used fermented soybean meal to replace 10% equal-nitrogen fish meal, the growth of Litopenaeus vannamei was no significant difference between fermented soybean meal group and control group which there was high fish meal content. The ratio of body weight and body length of fermented soybean meal group was higher than control group in the end of breeding. In the experiment of raising Litopenaeus vannamei which used fermented mixed meal to replace 10% equal-nitrogen fish meal, the growth of Litopenaeus vannamei was no significant difference among fermented mixed meal group, ferment soybean meal group and control group. The experiment results showed that the fermented soybean meal and the fermented mixed meal can be used to replace partial fish meal in the breeding of prawns.
