Ecological riverside aquaculture farm

Abstract

The invention provides an ecological riverside aquaculture farm, comprising at least two culture ponds arranged in sequence along a river, and a diversion canal arranged at one side, close to a riverbank, of each culture pond and used for introducing water from the upstream. Each culture pond is provided with a water inlet facility and a drainage facility. The pond ridge at one side, close to a river center, of each culture pond is used as a flood control wall. The upstream of the river is equipped with a barrage for raising fish. The starting point of the diversion canal is connected with the barrage. The barrage of the invention is used for storing water and raising fish, and ensures that the water volume of the river is evenly abundant. The diversion canal diverts water from the barrage, and then the water source is supplemented for the culture ponds by water diversion pipes. The water diversion pipes can be rotated and adjusted, when water is required to be diverted, pipe mouths are directed towards the water coming direction, and water from the diversion canal is poured into the culture pond from the water diversion pipes, and when water is not needed, the pipe mouths are moved upwards. Drainage pipes at the bottom of the flood control wall are responsible for discharging water in the culture ponds into the river when water change is needed.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an ecological riverside aquaculture farm. 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 rate is l...

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.
