1 给鱼播放音乐加快生长 日本渔业专家通过试验证实,给鱼播放音乐能增加鱼产量。将大功率扬声器安装在鱼池旁,每次投喂饲料时,即将扬声器打开,播放各种音乐,众多的鱼就会闻声赶来,聚在一起“会餐”。采用这种方法,不仅可提高饲料利用率,还能加快鱼的生长,提高鱼产量。2 脂肪饲料促进鱼苗生长 英国西部渔业实验站经过多年研究和实践证实,在内含蛋白质30～32％,能量为1.4×10~6J/kg的半精制饲料中再添加4～8％的脂肪(动物性或植物性油脂均可,以脂肪酸甘油三酯为最好)喂养鱼苗时,鱼苗的生长速度比对照组快30％,同时死亡率
1 to play music to accelerate the growth of fish Japanese fisheries experts confirmed through experiments that giving fish music can increase fish production. The high-power speakers installed next to the fish pond, each feeding feed, the speaker is about to open, play a variety of music, many fish will smell heard, get together “meal.” Using this method, not only can improve feed utilization, but also accelerate the growth of fish, increase fish production. 2 fat feed to promote the growth of fish fry After years of research and practice, Western Fisheries Experimental Station has confirmed that in the semi-refined feed containing 30 ~ 32% protein and 1.4 × 10 ~ 6J / kg energy, 4 ~ 8% fat Animal or vegetable fats can be, with fatty acid triglycerides as the best) feeding fry, fry growth rate of 30% faster than the control group, while the mortality rate
