Description

Crayfish feeding trough

Technical Field

The utility model belongs to the aquaculture field, in particular to crayfish feeding groove.

Background

In the process of lobster aquaculture, the problems of low yield, high labor cost, water source waste, more medicine application, more enemies, difficult catching and the like can occur in the field pond culture and shrimp and rice mixed culture mode; in addition, artificial uncontrollable factors can also occur in the outdoor culture environment to cause culture failure, and the field pond culture and shrimp and rice mixed culture are influenced by seasonal environment temperature and cannot be continuously cultured all year round; the crayfish breeding process needs to pay special attention to crayfish habits, for example, during the breeding process, crayfish food competition and spouse competition are paid attention to the situation that crayfish food fighting and crayfish eating each other, crayfish has drilled holes, crayfish shelling needs to be hidden, and crayfish has the habit of sliding edge and sliding bottom, so if artificial breeding is carried out, a breeding device needs to be designed according to crayfish habits.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the problem that uncontrollable situation and some artificial breeding are not conform to cray life habit can appear to outdoor breeding cray among the prior art, has provided a cray rearing groove.

Technical scheme

The utility model provides a crayfish raises groove, includes the basin, is equipped with in the basin: the step part is arranged close to the side edge of the water tank, and a row of culture holes are formed in the side surface of each step of the step along the length direction; the movable part is a vacant part on the bottom surface of the water tank and comprises a slope surface, the slope surface extends downwards from the bottom of the ladder to the bottom surface of the bottom of the water tank, and a sewage draining outlet is formed in the bottom surface.

Further: the bottom surface is a concave surface pointing to the sewage draining exit.

Further: and a pipeline is inserted into the sewage discharge outlet.

Further: the step portion includes two steps partially provided at opposite sides of the sink, and the movable portion is located between the two steps.

Further: the depth of the culture holes is 15-20 cm, and the width of the culture holes is 6-8 cm.

Further: one or more of oxygenation equipment, circulating water equipment and feeding equipment are arranged in the water tank.

Advantageous effects

1. The steps are arranged in the water tank, the breeding holes are formed in the side faces of the step steps, crayfish food can be uniformly scattered on the platform of the step before the hole during breeding, natural habits of drilling holes for the lobsters are met, the lobsters are not influenced when going out of the hole to find food, the step platform can provide more shelling places for the lobsters, the step design accords with the habit that the lobsters slide along the edge and slide down the bottom, and the breeding density can be increased due to the step breeding hole structure;

2. a pipeline is inserted into the sewage draining exit to prevent the crayfishes from climbing out of the sewage draining exit and prevent waste water or waste gas in the pipeline connected below the sewage draining exit from returning to the water tank to pollute the water body;

3. the depth of the breeding holes is 15-20 cm, the breeding holes accord with the living habit of the crayfish, the breeding holes are 6-8 cm in width, and the breeding holes accord with the mating requirement of the crayfish clustering;

4. the water tank is internally provided with an oxygen increasing device and a water circulating device, so that the water quality is improved, and the water tank is suitable for the growth of crayfish.

5. The equipment can be used for industrial constant-temperature culture and can be used for continuous culture all the year round.

Detailed Description

The crayfish feeding trough comprises a water trough, wherein: the lobster breeding device comprises a step part 1, wherein the step part 1 is arranged close to the side edge of a water tank, the step part 1 in the water tank comprises a group of steps arranged on two opposite sides of the water tank, a row of breeding holes 3 are formed in the side surface of each step of the steps along the length direction, the breeding holes 3 are formed in the side surface of each step of the steps, and the food below the lobsters can be uniformly scattered on a step platform in front of a hole, so that the natural habit that the lobsters like drilling the hole is met, and the lobsters are foraged when going out of the hole and do; the step platform can also provide more shelling places for the lobsters, the design of the steps accords with the habit that the lobsters have sliding edges and sliding bottoms, and the step type culture structure can also increase the culture density; the depth of the breeding holes is 15-20 cm, the width of the breeding holes is 6-8 cm, and the requirements of living and cohesive mating of crayfish can be met; the movable part 2 is a vacant part on the bottom surface of the water tank and can meet the requirements of lobster movement, cleaning and the like, the movable part 2 is arranged between the steps in the graph 1, the movable part 2 comprises a slope surface 4, the slope surface 4 extends downwards from the bottom of the steps to the bottom surface 5 of the bottom of the water tank, a sewage draining outlet 6 is arranged at the bottom surface 5, the slope surface 4 is arranged to facilitate water flowing to the bottom surface 5 where the sewage draining outlet 6 is located when washing, the bottom surface 5 is a concave surface pointing to the sewage draining outlet 6 and facilitates the wastewater to be led to the sewage draining outlet 6 when washing, a pipeline 7 is inserted into the sewage draining outlet 6, the sewage draining outlet 6 is blocked when not needing to be washed, waste gas or wastewater in the pipeline below the connected sewage draining outlet 6 is prevented from flowing back to pollute the aquaculture water body, and the pipeline is pulled; one or more of an oxygen increasing device, a circulating water device and a feeding device can be arranged in the water tank, aquatic plants can be planted in the water tank, beneficial fungi and algae are cultivated, various requirements for lobster cultivation are met, and the steps can be made of plastic materials.

Place the basin indoor during use, then can control indoor environment and accord with the cray and raise, put in the basin with the cray, put bait on the platform of step when throwing the food, when needing to wash, pull out pipeline 7, wash with the water pipe can.
