近年来,我国400多万吨的鱼产量中,由于加工和保鲜能力不足,每年大约有40万吨左右的鱼腐烂变质不能食用,大部分成为鱼肥。也就是说,这部分高蛋白原料既不能作为食物直接利用,也不能被家禽、家畜作为饲料,而是直接地作了植物的肥料。当然,成为鱼肥的鱼,一般都是质量不太好的下杂鱼,多数是体小,骨刺多、肉质不好、经济价值不很高;也有少量是优质鱼。这些鱼所以成为鱼肥,主要是七、八、九三个月气温高,微生物繁殖迅速,鱼体内酶的活性增加,造成了鱼的腐败。 In recent years, of the more than 4 million tons of fish in China, about 400,000 tons of fish spoilage can not be eaten every year due to the lack of processing and preservation capacity, and most of them become fish fat. In other words, this part of the high-protein raw material neither as a direct use of food, nor poultry, livestock as feed, but directly as a plant fertilizer. Of course, as a fish fat fish, are generally not very good quality trash fish, most of the body is small, bone spurs and more, poor quality, economic value is not high; there are a small amount of high-quality fish. So these fish become fish fat, mainly seven, eight, ninety-three months high temperature, rapid microbial growth, increased activity of fish in the enzyme, resulting in the fish’s corruption.
