Method for completely and artificially breeding palaemon carinicauda parent shrimps indoors

Abstract

The invention provides a method for completely and artificially breeding palaemon carinicauda parent shrimps indoors and belongs to the technical field of palaemon carinicauda artificial breeding. The method comprises the steps of water quality control, larval shrimp selection, density setting, water temperature control, feeding and water change, gonad development adjustment and gonad mature judgment. The water quality control is that water temperature is controlled to be 24-28 DEG C in the whole breeding process. The feeding and water change is that a matched feed is fed before the palaemon carinicauda grows to 2cm, clam meal and fresh alive clam worms are fed when the palaemon carinicauda grows to 2cm, and the daily water changing amount is 20%-30%. The gonad development adjustment is that when female shrimp ovaries develop to an II-III period, female shrimps identical in gonad development degree are bred in the same aquarium, and breeding water temperature of a group of shrimps with low gonad development speed is improved by 2-4DEG C. The gonad synchronous development and mature of palaemon carinicauda are achieved through feed selection, density setting and water temperature control in the breeding process of the palaemon carinicauda parent shrimps, and large-scale indoor artificial breeding of the palaemon carinicauda is facilitateed.

Description

technical field [0001] The invention belongs to the technical field of artificial breeding of white prawns, and in particular relates to a method for cultivating broodstock of white prawns indoors. Background technique [0002] The ridgetail white shrimp (Exopalaemon carinicauda) belongs to Arthropoda, Crustacea, Decapod, Longarmidae, and White Shrimp. It is mainly distributed in the shallow sea and low-salt waters along the coast of the entire mainland of China and the west coast of the Korean Peninsula. Because of its small size, short reproductive cycle, fast growth, sensitivity to toxicity, and easy breeding (Li Xinzheng et al., 2003; Zheng Yanjing et al., 2006; Wang Libao et al., 2008), it is an important research field in crustacean development, genetics, Ideal experimental animals for pharmacology, toxicology and disease studies. However, since the large-scale artificial breeding of white prawns has not yet been successfully solved, the source of broodstock mainly de...

AI Technical Summary

Problems solved by technology

However, since the large-scale artificial breeding of white prawns has not yet been successfully solved, the source of broodstock mainly depends on fishing broodstock broodstock in the offshore in spring or fishing overwintering broodstock in cement ponds in autumn (Xu Guocheng et al., 2008; Lin Jicai et al., 2009; Zou Shengli et al., 2009), sexual maturation is not synchronized, and it is easy to carry and spread pathogens (Wu Youlu et al., 1995; Xu Wenjun et al., 2010; Li Xincang et al., 2012), resulting in unstable seedling yield, easy disease, and low success rate
