High survival rate culture method for coreius guichenoti fry

Abstract

The invention provides a high survival rate cultivation method for coreius guichenoti fry. Well water is adopted as a water source, and fewer pathogens exist for breeding the coreius guichenoti. Different feeds are provided in different stages according to the physiological needs of the coreius guichenoti fry in different stages, corresponding palatable feeds are adopted, the growth speed of the fry is effectively increased, the fry are healthy and strong, the physical fitness is good, the disease resistance is high, and the fry survival rate is high. An underwater material is obtained by means of modified diatomite loaded polysilicate aluminium ferric, cerous sulfate, sodium humate, and serratia grimesii metabolite (serratia grimesii ACCC01695 is obtained through activation, inoculation and fermentation). The water environment is improved, the incidence is greatly reduced, and the survival rate is improved.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating round-mouth copper fish fry with high survival rate. Background technique [0002] Coreius guichenoti (Sauvage et Dabry) belongs to the genus Cyprinidae, Subfamily, and Bronze. The local names are: square head, water cleavage, round mouth, fat tuo, square head water mites, sand shell crucian carp (Minjiang) ), An Maoyu (Yunnan Duomei), Pigeon Fish, Beard Fish (Middle Reach of Jinsha River), Twisted Fish, etc. It is common in the upper reaches of the Yangtze River, the middle and lower reaches of the Jialing River, the Tuojiang River, the lower reaches of the Jinsha River, and the lower reaches of the Wujiang River (Ding Ruihua, 1995; Liu Lehe et al., 1990). It is a unique fish and an important economic fish in the upper reaches of the Yangtze River. The round mouth copperfish is tender, fat and rich in fat (Ding Ruihua, 1995). It is an important economic ...

Problems solved by technology

[0004] At present, the research reports on copperfish mainly involve biology (Yu Zhitang et al., 1984; Zheng Shuming, 1988; Huang Xiu and Deng Zhonglin, 1990; Zheng Shuming and Wu Qing, 1998; Zhang Guohua et al., 1999; Ge Qingxiu et al., 2001; Zhang Xianfang et al., 2005), physiology and biochemistry (Wang Youhui et al., 2005; Wang Youhui et al., 2005; Li Rong et al., 2008; Liu Jun et al., 2008; Wu Bin et al., 2008), molecular genetics (Liao Xiaolin, 2006; Xu Shuying, 2007; Yuan Xiping Ping, 2008; Kong Yan, 2010), resources (Yu Gongliang et al., 2002; Yang Zhi, 2009; Yang Zhi, 2011), ecological habits (Liu Lehe et al., 1990; Cao Wenxuan, 2008), etc., Yuankou The artificial cultivation of copperfish fry is still in a preliminary research stage, the conventional method of fry cultivation has a high morbidity rate and a low survival rate.
