细鳞斜颌鲴是一种重要的经济鱼类,其食性是以腐植质、有机碎屑和着生藻类等为主要食物,与“四大家鱼”混养,可充分利用水体饵料资源,在一般湖泊、水库中,只要有一定的流水条件,即能自然繁殖,并可望形成天然种群;加之斜颌鲴又具有疾病少、易捕捞及群体产量高等优点。对于水库鲴类自然种群的形成、繁殖的生态学尚未见专题研究报道。根据斜颌鲴的生物学特性,作者认为它在水库的增殖潜力大,并有十分重要的渔业价值。为此,我们对同欢水库细鳞斜颌鲴产卵场的分布、底质、水温、水深,流速、酸碱度、溶解氧等自然条件及产卵季节、时间与产 Squamata maxium is a kind of important economic fish whose diet is humus, organic detritus and algae as the main food, and “four big fish” polyculture, which can make full use of water bait resources in the In general lakes, reservoirs, as long as there is a certain flow conditions, that is, natural breeding, and is expected to form a natural population; combined with oblique jaw gall and disease less easy to catch and the advantages of high yield groups. For the formation of natural populations of 鲴, species, breeding ecology has not yet seen the special report. According to the biological characteristics of Obliquus oblique, the author believes that it has great potential for proliferation in reservoirs and has very important fishery value. For this reason, we analyzed the natural conditions such as distribution, sediment, water temperature, water depth, flow rate, pH, dissolved oxygen and spawning season, time and production
