1986年由东海水产研究所设计的86-A添加剂,在养鳗饲料中按干重3%的量添加,曾在浙江省水产厅淡水水产试验场进行过养殖试验。试验确认,该种添加剂能提高鳗鱼对饲料的摄食强度,加速鳗鱼的生长。1987年为了验证试验结果的可靠性,又在上述试验场进行了扩大试验。现将试验情况报告如下: 一、材料和方法1.1 试验鳗种取该试验场经1986年越冬的30克左右的小规格鳗种684公斤和80克左右的大规格鳗种1118公斤,大小规格鳗种各分为两组,计四组。1.2 试验池池塘4个,每个2亩。其中两个塘养小规格鳗种,另外两个养大规格鳗种。
86-A additive designed by the East China Sea Fisheries Research Institute in 1986 was added in an amount of 3% of the dry weight of the eel feed. Aquaculture experiments were conducted at the Freshwater Aquatic Experimental Station of Zhejiang Provincial Fisheries Department. The experiment confirmed that this kind of additive can improve the feeding strength of eel on feed and accelerate the growth of eel. 1987 in order to verify the reliability of the test results, but also in the above test site to expand the test. Now the test report as follows: First, the material and methods 1.1 test eel species to take the test site overwintering in 1986, about 30 grams of small eel species 684 kg and about 80 grams of large-scale eel species 1118 kg, the size of the eel The species are divided into two groups, accounting for four groups. 1.2 Test Pond 4, each 2 acres. Two of the ponds raise small-format eel species and the other two raise large-format eel species.
