The technology of artificial culture of large white fish in Heilongjiang reclamation area is leading in China

Introduction: Heilongjiang reclamation area undertakes the key scientific research project of the Ministry of agriculture, "Research on the whole artificial culture technology of Xingkai Lake white fish", which has recently passed the expert appraisal organized by the Chinese Academy of Fishery Sciences According to the expert group, "the whole artificial culture technology of Xingkai Lake white fish is at the leading level in China, which fills the gap in China and reaches the international leading level." Large white fish is a widespread fish There are traces of large white fish in Heilongjiang, Liaohe, Yellow River, Yangtze River and other rivers in China However, Xingkai Lake in 8510 farm of Heilongjiang Province is far away from industrial pollution sources, with fresh water, rich nutrients, silvery white body, white and tender meat, and delicious taste It is one of the rare fish species in China, and forms an independent population In history, Xingkai Lake white fish was once a tribute of the royal family, and now it is also a delicacy on the dining table for VIP guests As a result of overfishing, the natural growth of large white fish has become increasingly rare In order to effectively protect and reasonably develop this precious resource, the aquatic technicians of 8510 farm, who live with the lake, have undertaken the research on the application technology of the key scientific research plan of the whole artificial feeding of white fish in Xingkai Lake since 1987 The technicians fished out the young fish of Xingkai Lake, which grew naturally, and put them into the artificial pond for domestication and cultivation until they are sexually mature, and hatched the seedlings of the big white fish under the artificial conditions After more than 10 years of repeated feeding experiments, it has been successful in the breeding techniques of reserve parent fish, artificial spawning and hatching, and adult fish feeding The rate of artificial spawning and hatching is 80% After three years of feeding, the 10 cm fish can grow to 1.3-1.8 kg (author:) share to feed Weibo share to:
