Description

High-density aquaculture method

Technical Field

The invention belongs to the field of agricultural cultivation, and particularly relates to a high-density aquaculture method.

Background

In aquaculture, snails have increasingly broad culture prospects due to delicious, crisp and refreshing meat quality, for example, snails (such as Babylonia and the like) need to be cultured in a culture pond at high density in actual production, sand is laid on the bottom of the culture pond, the snail is usually hidden in the sand, when eating, the snail climbs out of the sand to eat, as the feces and food residues of the snails can remain in the sand in the culture pond for a long time, the impurities hidden in the sand can go moldy and further influence the water quality of the culture pond to directly influence the growth of the snails and even cause the death of the snails, the existing method for preventing sand from deteriorating by periodically pumping water in the culture pond and then replacing the sand wastes time and labor, meanwhile, the water in the culture pond is cut off every time, the snails are collected in a centralized mode, and then the snails are released and drained, which is completely similar to the situation that the snails are replaced by a new living environment, so that the cost of snail culture is increased, and the emergency reaction of the snails is easily caused; moreover raise personnel and often regularly put into feed material (dead fish) in breeding the pond at the in-process, when the feed material falls into behind the bottom of the pool large batch spiral shell and climbs on the feed material and eat, the residue of feed material after the food finishes often can be stayed and need personnel to clear up alone in breeding the pond.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides a high-density aquaculture method which is used for solving the problem that sand at the bottom of a culture pond is easily polluted in the culture process.

In order to achieve the purpose, the invention adopts the following technical scheme: a high-density aquaculture method comprising the steps of:

fixing the bottom of the partition plate on the upper part of the spring to ensure that the limiting groove is matched and corresponding to the sliding block, and forming a culture chamber between the interior of the partition plate and the inner side wall of the culture pond;

paving sand in the partition plate, and enabling the height of the sand to be smaller than that of the partition plate;

injecting water into the culture pond to form a water layer, wherein the height of the water layer is larger than that of the baffle when the baffle is static;

dead fishes are fixed on the leather strip net through the limiting strips, so that the fishes can be conveniently collected through the outer framework directly at the later stage;

the supporting plate is placed in alignment with the clamping groove, so that the height of the water layer is greater than that of the upper end face of the outer framework, and meanwhile, the bottom of the adsorption net is abutted to a sand layer in the culture room;

the snails enter the leather strip net through the adsorption net under the attraction of the fish and feed the fish fixed in the leather strip net by shuttling in the feeding gap;

after the fish in the leather strip net finishes eating, the fishbone is limited and fixed on the leather strip net by the limiting strip;

the support frame is opposite to the two sides of the support frame, and forces in the C direction and the D direction are simultaneously applied, the forces in the C direction and the D direction are both vertically downward, the support frame moves downward under the action of the forces in the C direction and the D direction and drives the framework to move downward, and the framework further pushes the spring downward to enable the spring to deform;

the force in the direction C and the force in the direction D are cancelled, and the inner framework and the outer framework move upwards to reset under the action of the springs;

during the reciprocating motion of the lower framework and the outer framework, water at the bottom of the lower framework surges, water flow continuously surges upwards along the through holes and through sand in the partition plate, impurities wrapped in the sand also float upwards along with the surge of the water flow, and the impurities are finally adsorbed by the adsorption net;

the outer framework is separated from the inner framework, the outer framework is taken out of the culture pond, and fishbones and other impurities in the outer framework are cleaned.

The high-density snail culturing method further comprises the following steps: place the fish on the leather strip net, remove spacing to the position department that is close to fish upper portion, then pull spacing with the couple of spacing and pass the feed clearance and realize the fixed of spacing position, and then be fixed in the leather strip net with the fish through spacing, be fixed in the leather strip net through spacing with the fish.

An inner framework and an outer framework are further arranged in the culture pond, and the outer framework is arranged on the upper portion of the inner framework.

Further interior framework bottom passes through spring and breed pond fixed connection, and interior framework can be dismantled with outer framework and be connected, and outer framework bottom is fixed and is adsorbed the net.
