黄板刁学名细鳞斜颌鲴和黄尾密鲴。我县试养推广已全面获得成功,1991年池塘套养1.3万亩,平均亩产29.1公斤,湖泊套养2.1万亩,平均亩产2.1公斤,共产鲴鱼411吨,总产值140万元,纯利润126万元。生产实践已充分揭示了它的秘密。 1.习性特征。黄板刁原系天然水域自然生长繁衍的一种优质鱼类,性温和,耗高氧。过去,许多水产工作者认为它难于移殖到精养塘。可实践证明,它不仅适宜广泛地套养于精养塘,并且不需发花育种,精养塘每亩直接套养1000尾鱼花(下塘10天内禁止施用毒性鱼药),下塘前在塘边水中撒些菜籽壳,有利于鱼苗栖息和生长发育,成活率高达60～80％。它长到夏花阶段后,便长期生活在水体最上层,由于水体上层光合作用强,溶氧高,故其生长正常,平时也未发
Yellow plate Diao Xue name fine scales oblique jaw 鲴 and yellow tail 鲴. Pilot promotion in our county has been fully successful. In 1991, 13,000 mu of ponds were raised, with an average yield of 29.1 kilograms, 21,000 mu of lakes, an average yield of 2.1 kilograms, a total of 411 tons of common catfish, a total output value of 1.4 million yuan, Net profit of 1.26 million yuan. Production practice has fully revealed its secrets. 1. Habitual characteristics. Yellow Diaobia original natural water system is a kind of high-quality natural fish breeding, mild, high oxygen consumption. In the past, many aquatic workers thought it difficult to colonize intensive ponds. Practice can be proved that it is not only suitable for a wide range of nursed back to the intensive ponds, and do not need to send flowers breeding, intensive ponds directly supporting 1000 fish per acre (Xia Tong 10 days to prohibit the application of toxic fish drugs), Xia Tong Sprinkle rapeseed shell in the pond water is conducive to fish habitat and growth, the survival rate as high as 60 ~ 80%. It grows to the summer flower stage, they long-term living in the top of the water body, due to the upper water photosynthesis, high dissolved oxygen, so the growth of normal, usually not yet
