Inner-circulation aeration device for fish culture pond and use method of inner-circulation aeration device

Abstract

The invention relates to an inner-circulation aeration device for a fish culture pond and a use method of the inner-circulation aeration device, and belongs to the technical field of culture. The device comprises a base, a submersible pump, a support, a water taking tube, a tee tube, an air inlet tube, a water outlet tube, a jet pipe, a remote control switch and a cable, wherein the submersible pump is placed on the base and connected with the water taking tube, the water taking tube is connected with the air inlet tube and the water outlet tube through the tee tube, one horizontal port of the tee tube is connected with the water taking tube, the other horizontal port is connected with the water outlet tube, the port perpendicular to the water surface is connected with the air inlet tube, and the water taking tube and the water outlet tube are connected on the same straight line through the two horizontal ports of the tee tube. By means of the inner-circulation aeration device arranged in the pond, exchange of water on the upper and lower layers and aeration are realized, culture water in the pond is pushed to form inner circulation flow, concentrated cleaning of large-particle culture waste is convenient, the fine fish growth environment is created, the disease rate caused by substrate decomposition and water degradation in the pond is greatly reduced, the culture survival rate and the culture yield of the fish pond are increased, and the purposes of quality and efficiency improvement of pond culture production are achieved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an internal circulation aeration device for fish culture ponds and a use method thereof. Background technique [0002] The area of ​​aquaculture ponds in my country reaches 3.118 million hectares (National Fishery Statistical Yearbook, 2015), which is the main carrier of fish aquaculture production in my country. The pond culture environment is similar to the natural environment, the cost of culture is low, and the quality of the fish produced is good, which is deeply loved by consumers. Good water quality is a prerequisite for the smooth progress of fish pond culture. However, in the process of fish pond culture in my country, there are still some technical problems to be overcome in terms of water quality control and management. For example: (1) Due to the geographical Due to limited conditions, the pond can only be fed and drained during high tide and low tide,...
