Handheld bottom suction apparatus for intensively cultivating Penaeus Vanmamei

Abstract

The invention discloses a handheld bottom suction apparatus for intensively cultivating Penaeus Vanmamei, and the handheld bottom suction apparatus is the T-shaped one composed of a horizontal PVC (polyvinyl chloride) hard tube, a vertical PVC hard tube and a flexible tube. The head of the T-shaped bottom suction apparatus is composed of the horizontal PVC hard tube with two sealed ends and the inner diameter of 100cm, and the side of the horizontal PVC hard tube is provided with a water feeding seam with the width of 1cm and the same length as the PVC hard tube. The 135 degrees arc position formed between horizontal PVC hard tube and the water feeding seam is provided with a circular hole with the diameter of 50cm, and the circular hole is connected with the vertical PVC hard tube with the outer diameter of 50cm. The tail of the T-shaped bottom suction apparatus is connected with the tail end of the vertical PVC hard tube by the flexible tube. The handheld bottom suction apparatus can solve the bottom-clearing problem when the Penaeus Vanmamei is cultivated by an improved sea slug nursery pond, and the handheld bottom suction apparatus is used to intensively cultivate the Penaeus Vanmamei.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a hand-held bottom suction device for intensive cultivation of Penaeus vannamei. Background technique [0002] The intensive culture of Penaeus vannamei is developing rapidly nationwide. The supporting facilities and technology for the cultivation of Penaeus vannamei using the original sea cucumber nursery ponds need to be further improved, and some more effective tools and facilities need to be studied as soon as possible to solve the actual production problems. problems in the process. In the intensive culture ponds of Penaeus vannamei transformed from sea cucumber nursery ponds, in order to maintain the stability of the water environment, the water cannot be changed from the bottom drain pipe, and some harmful substances such as residual bait and feces will accumulate at the bottom of the culture ponds, which are prone to occur after a long time. Ammonia nitrogen, hydrogen sulfide ...

AI Technical Summary

Problems solved by technology

In the intensive culture ponds of Penaeus vannamei transformed from sea cucumber nursery ponds, in order to maintain the stability of the water environment, the water cannot be changed from the bottom drain pipe, and some harmful substances such as residual bait and feces will accumulate at the bottom of the culture ponds, which are prone to occur after a long time. Ammonia nitrogen, hydrogen sulfide and other toxic substances have a great impact on Penaeus vannamei, and if they are not treated in time, the yield may drop significantly
