Feeding table for mixed cultivation of fish and shrimp

Abstract

The invention provides a feeding table for mixed cultivation of fish and shrimp. The feeding table mainly comprises an oblique support arranged on the top, and a main support connected with the bottom of the oblique support, wherein the top end of the oblique support is connected with a floating ball; at least two circular net racks which are arranged at intervals along the vertical direction are fixed in a space defined by the main support, and the bottom side of the circular net rack arranged at the lowermost side is flush with the bottom end of the main support; the bottoms and the side faces of the circular net racks are wrapped with bottom net pieces; a feeding table main body is defined by the oblique support and the main support, and the side faces and the top of the feeding table main body are wrapped with purse net pieces. According to the feeding table, the number of the circular net racks can be increased according to the depth of water in a pond and the total stocking number of fish and shrimp, so that the aims of enlarging the feeding area and increasing feeding efficiency can be achieved; the apertures of the purse net pieces vary according to the individual sizes of the fish and the shrimp, and the bred shrimp can freely enter a purse net to eat feed, but the fish bred by means of mixed cultivation cannot enter the feeding table for robbing the shrimp feed, so that the aim of separated feeding in a fish and shrimp mixed cultivation pond is achieved.

Description

technical field [0001] The invention relates to the technical field of a food platform for feeding fish and shrimp in aquaculture, in particular to a food platform for mixed cultivation of fish and shrimp. Background technique [0002] Since the introduction of Litopenaeus vannamei into Chinese culture, with the expansion of the culture area and the continuous increase of stocking density, shrimp diseases have occurred frequently, and the success rate of culture has decreased year by year. In 2015 and 2016, the market was the lowest in the history of shrimp culture. If the existing fish and shrimp polyculture mode is not improved and a more stable fish and shrimp polyculture mode is not explored, it will be difficult to adapt to the new farming development trend. [0003] At present, in the ponds where fish and shrimp are mixed, the main disadvantage of breeding lies in the way of feeding. The shrimp feed in the traditional food table only accounts for a few percent of the ...

AI Technical Summary

Problems solved by technology

Such a feeding method cannot achieve separate feeding of fish and shrimp, and mixed fish cannot play an ecological disease prevention role, resulting in a high incidence of disease and a low breeding success rate

When the fish get the food of the shrimp, they cannot actively remove the pollution sources of the water body in the pond, such as sick and dead shrimp, residual bait, feces and organic flocs, etc., which will seriously damage the ecological balance of the water body
