Polyculture pond and polyculture method for penaeus monodon, holothuria scabra and siganus oramin

Abstract

The invention discloses a polyculture pond and a polyculture method for penaeus monodon, holothuria scabra and siganus oramin. The circumferential inner edge of the polyculture pond is provided with aslope. The polyculture pond is characterized in that several inhabitation piles are arranged close to the bottom of the slope and are alternately distributed around the edge of the polyculture pond,each inhabitation pile comprises a column and a ceiling located at the top of the column, and an impoundment cover is arranged around the middle of the column and faces the slope. Holothuria scabra isstocked in the impoundment covers, at the same time, penaeus monodon and siganus oramin are cultured in water in the polyculture pond together, and penaeus monodon is fed with bait regularly. By culturing holothuria scabra and siganus oramin together in the polyculture pond where penaeus monodon is mainly cultured, bottom mud dirt and water algae in the polyculture pond can be effectively controlled respectively, it is guranateed that both the bottom of the polyculture pond and water in the polyculture pond can meet growth conditions of penaeus monodon all the time, and polyculture in this way provides a good economical culture mode.

Description

technical field [0001] The invention relates to a three-dimensional aquatic polyculture technology, in particular to a polyculture pond and a polyculture method of Penaeus monodon, rough sea cucumber and basket fish. Background technique [0002] Commonly known as ghost shrimp, grass shrimp, flower shrimp, and bamboo shrimp, Penaeus monodon is widely saline, can withstand high temperature and low oxygen, and has weak adaptability to low temperature. Strong disease resistance. The individual is large, the shell is thicker, and the edible ratio is lower than that of Chinese prawns. The meat is delicious and nutritious. The body shell is relatively solid and can withstand being caught by hand. After leaving the water, it has a strong endurance to dry and expose to the air, so it can be sold as a live shrimp. Coarse sea cucumber has high nutritional value and medicinal value, and is one of the more popular edible sea cucumbers in southern my country. It is a high-temperature...

AI Technical Summary

Problems solved by technology

Due to the eutrophication of the water body in the natural environment, it is often difficult to effectively control the growth of algae in the existing shrimp culture ponds, causing a large amount of algae to grow out of control in the culture ponds, which in turn leads to the occurrence of malignant conditions such as water hypoxia. The pollution of sludge, residual bait and feces, etc., the growth environment of prawns is getting worse and worse, which brings no big disadvantages to the prevention and control of aquaculture prawn diseases
