近几年,黄鳝的市场价格居高不下,因此在鳝鱼捕捞旺季进行暂养是一种投资少、见效快的养殖项目。 一、养殖前的准备工作 (一)要养鳝必先了解其生活习性 鳝鱼为底栖生活鱼类,白天隐居在洞穴或水草中,晚上出来觅食,以小鱼、虾、水生昆虫、蚯蚓等动物性饲料为主食(在食物缺少时,也食麸皮和植物碎屑)。适宜的温度为15℃一30℃之间,其生长最佳温度在24℃—28℃。低于10℃进入冬眠状态,高于32℃会出现不适反应(食欲减退)。温度太高会停止摄食甚至死亡。
In recent years, the market price of eel so high, so the eel fishing season for holding is a less investment, quick breeding project. First, the preparation before breeding (A) to eel must first understand their habits Eel as benthic life of fish, hidden in caves or plants during the day, come out at night to feed, fish, shrimp, aquatic insects, Earthworms and other animal feed as the staple food (in the absence of food, but also eat bran and plant debris). The optimum temperature is between 15 ℃ and 30 ℃, and the optimal growth temperature is between 24 ℃ and 28 ℃. Below 10 ℃ into the hibernation state, above 32 ℃ will appear unwell reaction (loss of appetite). Temperature is too high will stop feeding and even death.
