Composite type freshwater fish culture pond

Abstract

The invention discloses a composite type freshwater fish culture pond. The freshwater fish culture pond includes a cuboid pond body, a partition wall is arranged in the pond body and partitions the pond body into a growth pond and a fishing pond, the pond bottom of the growth pond is oblique, and the bottom surface of the growth pond gradually ascends from the end away from the fishing pond to theend close to the fishing pond; the bottom surface of the fishing pond is lower than the highest point of the bottom surface of the growth pond, a water gate is arranged on the partition wall and internally provided with an openable gate, and a rollable sunshade is arranged above the pond body. The composite type freshwater fish culture pond has the advantages that during culture, the gate can bemaintained in a closed state to separate the growth pond from the fishing pond, and in a harvest period, a driving or feeding mode can be adopted for gathering fish groups at a gate end of the growthpond; by opening the gate, fishes flow into the fishing pond along with water, and more convenience is provided for fishing; a part of water is always reserved in the growth pond to continue culture of remaining fishes; meanwhile, during the seasons when the sunshine duration is long and the illumination intensity is high, by opening the rollable sunshade, the illumination reception time of the pond body can be controlled, and therefore a microorganism environment in the water is adjusted.

Description

technical field [0001] The invention relates to aquaculture facilities, in particular to a composite freshwater fish culture pond. Background technique [0002] Due to technological progress, intensified market competition and increased labor costs, modern fish farming is facing huge challenges. In order to improve the competitiveness of breeding factories, large-scale factory farming is the future trend, which requires the breeding factories to continuously improve the level of mechanization and automation and production management level to improve production efficiency. Many new technologies are constantly emerging in water quality monitoring, automatic oxygen supply, water purification and feeding, but there are no better devices in terms of light control and product fishing. For some aquatic products, light conditions greatly affect the ecological environment of microorganisms in the water, so sunshade measures are required to control the growth of microorganisms in the...

AI Technical Summary

Problems solved by technology

There are many new technologies emerging in water quality monitoring, automatic oxygen supply, water purification and feeding, but there are no better devices in terms of light control and product fishing.

For some aquatic products, lighting conditions greatly affect the ecological environment of microorganisms in the water, so sunshade measures are required to control the growth of microorganisms in the water. The current sunshade devices are still rough and inconvenient to operate

In the product fishing process, the fishing method of pond drainage and fishing nets is still the main method at present, and there is no more convenient fishing method. On the one hand, net fishing is time-consuming and labor-intensive. Large area of ​​water, and net fishing may cause damage to fish and affect product quality; on the other hand, a large amount of drainage is required before fishing, resulting in waste of water resources, and subsequent breeding needs to add water, which affects production efficiency
