Artificial hatching culture pond for Schizothorax taliensis

Abstract

The invention provides an artificial hatching culture pond for Schizothorax taliensis. The artificial hatching culture pond comprises a hatching pond and a disinfectant pool, wherein the disinfectant pool comprises a sterilizing pool, a biochemical blanket pool, a biochemical ball pool and a filtering brush pool which are sequentially arranged and mutually communicated; the sterilizing pool is communicated with the hatching pond and is used for conveying purified clean water into the hatching pond; the filtering brush pool is communicated with the hatching pond and is used for performing purification treatment on sewage in the hatching pond; a net box is arranged in the hatching pond; an artificial fish nest is placed in the net box; an aerator is arranged at the bottom of the hatching pond; a temperature sensors is arranged on the pool wall of the hatching pond. The hatching pond provides a hatching environment with good water quality, abundant dissolved oxygen, proper temperature and proper water speed for hatching fish roes; in addition, high-quality water can be effectively and circularly provided for the hatching pond.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an artificial incubation pond for anti-wave fish. Background technique [0002] Kanglang fish is a unique indigenous fish in Fuxian Lake. Its meat is tender and delicious. It has been the main fishery target of fishermen along the lake throughout the ages. However, due to many factors such as the invasion of new whitebait in Taihu Lake and artificial overfishing, the population has dropped sharply, and the annual output has dropped from 300-400t in the 1960s and 1970s to 10t in 1998, 0.9t in 2001, and 0.9t in 2002. 1.2 tons per year. Due to the shrinking of population resources, the body of Kanglang fish has increased significantly, from 100-140mm of II-III age fish to 200-250mm, the proportion of older fish in the population has increased, and the population resources have aged. The current hatching technology is mainly natural hatching, and the hatching surviv...

AI Technical Summary

Problems solved by technology

The current hatching technology is mainly natural hatching, and the hatching survival rate is low, which cannot meet the market's demand for fighting against wave fish

Even though individual manufacturers have started artificial hatching and breeding, the hatching tanks they use are not clean enough for the water quality. During the long-term hatching process, the hatching efficiency is low, and even the phenomenon of no hatching occurs.
