我省江河纵横,水域广阔,鱼类资源丰富,蕴藏着许多有发展前途的经济鱼类.江河鱼类资源调查的任务之一,是为内塘、溪河养殖寻找新的品种,研究其生物学,为移养驯化提供科学依据.在嘉陵江鱼类资源调查中,根据各项生物学指标的分析研究,我们认为,我省特有的宜宾鲴,是一种优良的养殖对象.它具有适应性强,生长较快,性成熟早,肉质肥嫩的特点.以藻类和植物碎屑为食,不与“家鱼”争夺饵料,且能起到充分利用水体.充分利用饵料,又可高密度混养的增产效果.因此,作为在溪河、塘堰、水库中的移养驯化对象,是值得宣传推广的.这里对宜宾鲴的生物学性状作一简要介绍.
The rivers in our province are in a crisscross way with vast waters and abundant fish resources, which contain many promising economic fishes. One of the tasks of the investigation of fish resources in rivers and lakes is to search for new varieties for the cultivation of inner ponds and streams and study their organisms According to the analysis and research of various biological indicators, we think that Yibin, a peculiar species of Yibin in our province, is an excellent breeding target.It has the characteristics of adaptability Strong, rapid growth, sexual maturity, succulent characteristics of fleshy. To algae and plant debris for food, do not compete with the “domestic fish” for food, and can play a full use of water. Full use of food, but also high-density Therefore, it is worth to propagandize and promote as the object of acclimation and acclimatization in the river, pond and reservoir.A brief introduction about the biological traits of Yibin River is presented here.
