Ecological living water fish pond along river

Abstract

The invention provides an ecological living water fish pond along a river, which comprises a culture pond and a diversion canal, wherein the culture pond are at least two culture ponds, and the culture ponds are sequentially arranged and built along the river. The diversion channel for leading water from the upstream is built on one side of the culture pond close to the bank and each culture pondis provided with a water inlet facility and a water outlet facility. T pond ridge near one side of the river center of each culture pond is a flood prevention wall. A river dam capable of culturing fish is arranged at the upstream of the river and a starting point of the diversion channel is connected with the river dam. A water reservoir is also arranged at the outer side of the river dam and thewater reservoir is communicated with the inner side of the river dam through a water pump. The river dam provided by the invention is used for storing water and culturing fish and ensures that the water quantity of the river is uniform and abundant. The guide channel is used for guiding water from the river dam and then each culture pond is replenished with water supply through the water guide pipe, which can be adjusted in a rotating way. When the water guide is needed, the pipe orifice is oriented towards the direction of water and the water in the guide channel can be poured into the culture pond through the water guide pipe.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an ecological living water fish pond along a river. Background technique [0002] In recent years, with the development of the economy and society, the market demand for special aquatic species has become higher and higher, and the quantity is increasing. The amount of natural resources of rare and precious aquatic animals such as carp has been decreasing year by year, reaching the point of extinction. Due to the limitation of water sources, irregular pond construction, poor feed quality, gradual deterioration of the breeding environment, and the low technical level of the farmers, there are currently several major problems in white turtle farming in many parts of the country: First, the gonad development of broodstock is poor , the spawning rate generally only has about 50%, and the fertilization rate is about 60%, and the quality of the eggs is relatively poor, and the fertilization...

AI Technical Summary

Problems solved by technology

Due to the limitation of water sources, irregular pond construction, poor feed quality, gradual deterioration of the breeding environment, and the low technical level of the farmers, there are currently several major problems in white turtle farming in many parts of the country: First, the gonad development of broodstock is poor , the spawning rate generally only has about 50%, and the fertilization rate is about 60%, and the quality of the eggs is relatively poor, and the fertilization rate is low; the second is that the survival rate of large-scale fish species (5-8cm) is relatively low, generally only about 30%; The 3rd, the breeding cycle of adult fish is long, generally more than 3 years, and the survival rate (raised from 5~8cm fish fingerlings to about 600 grams of commercial fish) is only about 60%; The survival rate is low, and it seriously affects the quality of white soft-shelled turtles

The breeding of rare fish such as giant salamander, Dabry's sturgeon, Iwahara carp, mullet, and long-snout fish requires intensive flowing water aquaculture, but there is no scientific fish farm at present.
