Description

Dredging brush

Technical Field

The utility model belongs to the technical field of the aquaculture technique and specifically relates to a desilting brush of clearance intensive culture pond incomplete bait and excrement are dirty.

Background

The grouper in fresh water has the advantages of high growth speed, low oxygen resistance, strong disease resistance, beautiful appearance, delicious meat quality and rich nutrition, can be used as commercial fish and ornamental fish species, and is gradually a new species for fresh water culture due to the fact that the culture scale is larger and larger at present.

According to centuries, the freshwater grouper Cichlasomamanaguense is a Cipanaceous fish native to Nigalia melon in Central America. Introduced into our country in 1988. The strain is introduced into culture in 1996 by some culture units such as Guangdong and Jiangxi, the culture of the strain in Guangdong and Jiangxi is very successful, and the market price is high. The technology for culturing the grouper in the fresh water is continuously researched by aquatic workers in various regions in China, and the grouper in the fresh water is mature day by day, and the culture scale of the grouper in the fresh water is larger and larger, so that the grouper in the fresh water is an ideal new variety for culturing the fresh water. The freshwater grouper is tropical fish, and can grow in fresh water or seawater with salinity below 10 ‰. The suitable temperature range is 25-30 ℃, when the water temperature is reduced to 20 ℃, the ingestion is obviously reduced, and when the water temperature is reduced to 15 ℃, the body is out of balance, so that the pond water is reduced to below 15 ℃ in winter, which is not suitable for culturing the fishes. The water temperature is preferably kept at 19 ℃ or higher during the wintering period. The freshwater grouper is bottom layer fish, is resistant to hypoxia and strong in disease resistance, rarely causes fish diseases in the culture process, can be mixed with tilapia and crucian to remove small fish fries in the tilapia and crucian pond, and achieves the purposes of high quality and high efficiency. The grouper in fresh water is meat-eating-prone, the meat-eating characteristics are quite strong in the fry stage, mainly zooplankton is taken as a main part, fries with great individual differences can kill each other, and therefore the management of the pond in different grades needs to be paid attention to during cultivation. The bred fry is pulled out in time so as to prevent the fry from being swallowed by parent fishes. After fish fries are fed for domestication, the fish fries can eat artificial compound feed which can be fed by floating snakehead fish feed. The total length of newly hatched fries of the freshwater groupers is 0.58-0.6 cm, the fries clustered at the bottom of the pond ceaselessly move at the water temperature of 26-28 ℃, yolk sacs disappear after hatching on the 6 th day, the fries swim to the upper middle water layer and are not clustered at the bottom of the pond, the fries with disappeared yolks can be fed with rotifer, cladocera and other small zooplankton, and can be fed with tubificidae after being slightly larger, and then the fries are fed with ball-shaped eel feed for domestication, and can be bred in the pond after 1 month cultivation, and the fish with the body length of about 10 cm. Fry which are stocked in the southeast coastal areas and have the body length of about 10 cm are put into a pond in summer, and 500 g of the fry can be obtained after 6-8 months of culture. The maximum weight can reach 1200 g.

The grouper is rich in nutrition, tender and white in meat quality, similar to chicken, and called sea chicken as vegetarian. The grouper has high protein content and low fat content, and is rich in various inorganic salts, iron, calcium, phosphorus and various vitamins besides amino acids necessary for human metabolism. The nutrient components of the colloid of the rockfish skin play an important role in enhancing the complete growth of epithelial tissues and promoting the synthesis of collagen cells, and the rockfish skin colloid is called as fish with the functions of beautifying and protecting skin. Is especially suitable for postpartum women. The traditional Chinese medicine considers that the grouper is sweet in taste, mild in nature, non-toxic, high in nutritive value, high in medicinal value, and capable of promoting blood circulation to remove meridian obstruction.

The traditional pond culture mode has the advantages that the culture density of the groupers is high, the self-purification capacity of water is poor, the environments which are not beneficial to the growth of the groupers, such as eutrophication, over-standard water quality and the like are easily caused, the groupers grow slowly, the yield is reduced, the quality is reduced, and the development requirements of green healthy agriculture cannot be met. While farmers continuously pursue high yield, the problems of water pollution, ecological environment pollution, food quality safety and the like caused by residual baits, excrement, metabolites, drug residues and the like in the production are increasingly highlighted. High-density, high-investment, open and extensive pond culture aggravates the deterioration of the ecological environment and seriously restricts the sustainable development of the pond culture industry.

The freshwater aquaculture intensive culture pond such as the freshwater grouper has high culture density and large deposition amount of residual bait and feces, and can seriously influence the water quality when not being cleaned in time, improve the culture risk and reduce the culture benefit. At present, the method for cleaning the residual baits and the feces in the intensive culture pond mainly comprises suction and drainage by using a suction pipe, but the residual baits and the feces have high viscosity and are attached to the bottom of the pond and are difficult to pump and drain, and the residual baits and the feces are deposited more and more thickly along with the extension of culture time, so that the water changing frequency has to be increased for meeting the requirement of culture water quality, therefore, the culture cost is greatly increased, and the culture benefit is obviously reduced.

Disclosure of Invention
