Embodiment 1

[0012] The aquaculture virus prevention and control device of the present embodiment is composed of a circulation pump 1 and a filter box 2. The liquid inlet 1-1 of the circulation pump 1 communicates with the culture pond 3 through a pipeline, and the liquid outlet 1-2 is connected to the water inlet 2-1 of the filter box 2 . An angle steel support 2-6 is fixed on the casing 2-2 under this water inlet 2-1, and the orifice plate 2-3 of evenly distributed apertures is placed above it. The leaky orifice plate 2-3 also carries three layers of stainless steel expanded mesh 2-4 by the angle steel support. Each layer of expanded metal 2-4 supports and fixes chemical fiber filter cotton 2-5. The casing 2-2 under the expanded metal mesh 2-4 is shaped on the funnel-shaped water outlet 2-7 leading to the culture pond 3.

[0013] Under normal working conditions, the circulation pump 1 continuously pumps the seawater in the culture pond 3 into the filter box 2 . The seawater that enter...

Embodiment 2

[0017] The device used in this embodiment is the same as that used in Embodiment 1. The difference is that the rhizomes of marine green plants such as mangroves and ricegrass are directly tied and floated on the water surface of the breeding pool with open waters. This is more conducive to these plants receiving sunlight, performing photosynthesis, and more effectively inhibiting the reproduction and growth of viruses in seawater.

Abstract

An apparatus for preventing and eliminating the viruses in aquatic product alturing is composed of circulating pump and filter box. Said circulating pump has a water inlet communicated to the culturing pool and a water outlet connected with said filter box. Said filter box contains perforated plate, netted plate and filtering chemical fibre layer. It can effectively prevent and eliminate the white spot of prawn.

Description

technical field [0001] The invention relates to a device for preventing and treating viruses in aquaculture, in particular to a device for preventing and treating viruses in prawn culture. Meanwhile, the invention also relates to a method for preventing and controlling viruses in aquaculture, which belongs to the technical field of aquaculture. Background technique [0002] Prawns are delicious and nutritious, and are one of people's favorite seafood. Humans have fully understood the nutritional value of prawns and the resulting considerable economic value, so the artificial breeding of prawns has developed rapidly in recent years. Yet the wild prawn that grows in the marine natural environment can grow to more than 18 centimeters, but the prawn that can be cultured in the artificial breeding pond but can only grow to 5-7 centimeter long, will die if kept again. Therefore, compared with the wild prawns in the past, the artificially farmed prawns sold in large quantities on ...
