A kind of high survival rate breeding method of roundmouth copperfish fry

Abstract

The invention provides a high-survival-rate cultivation method for the roundmouth copperfish fry, which adopts well water as a water source, and the cultivation of the roundmouth copperfish has few pathogens. According to the physiological needs of the roundmouth copperfish fry at different stages, different feeds are provided at different stages, and the corresponding palatable bait is used to effectively improve the growth rate of the fry, the fry are strong, the physique is good, the disease resistance is good, and the survival rate of the fry is high. . The underwater material is obtained by using modified diatomite to load polyaluminium-ferric silicate, cerium sulfate, sodium humate, and metabolites of Serratia griseri (Serratia griseri ACCC01695 obtained by activation, inoculation, and fermentation). Improve the water environment, greatly reduce the incidence and increase the survival rate.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating copperfish fry with high survival rate. Background technique [0002] The round-mouthed copperfish Coreius guichenoti (Sauvage et Dabry) belongs to Cyprinidae, Scorpionidae, and the genus Copperfish. ), Anmao fish (Yunnan Duomei), pigeon fish, bearded fish (middle reaches of Jinsha River), mahua fish, etc. Commonly found in the main stream of 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 roundmouth copperfish is tender and plump, rich in fat (Ding Ruihua, 1995), and is an important economic fish in the upper reaches of the Yangtze River and an important fishing targe...

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.
