Description

Polyculture pond and polyculture method of Penaeus monodon, rough sea cucumber and basket fish

technical field

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

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-resistant, eurysalinous species that mainly uses organic matter in sediments as nutrients, and feeds on diatoms, bacteria, protozoa, cyanobacteria, foraminifera, and organic debris of animals and plants in the substrate. Typical sediment-feeding animals are cleaners of the marine environment. Sea cucumbers can accelerate the mineralization of sediments through strong feeding and bioturbation of sediments through burial, which is important for the stability of benthic habitat diversity. And the circulation of nutrients has a positive meaning. Bluefish is an omnivorous fish and can use algae as its main food. Practice has proved that prawn pellet feed is also an ideal food for it. 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., and the growing environment of prawns are getting worse and worse, which brings great disadvantages to the prevention and control of aquaculture prawn diseases. In the polyculture pond mainly raising Penaeus monodon, the control of the bottom dirt and algae in the water body is a problem to be solved in the prior art.

Detailed ways

The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

As shown in Fig. 1 and Fig. 2, a kind of polyculture pond of Penaeus monodon, rough sea cucumber and basket fish, the inner edge of the polyculture pond has a slope surface, near the bottom of the slope surface are provided with several perch piles, several The perching piles surround the edge of the polyculture pond and are arranged alternately. The perching piles include a column and a ceiling on the top of the column. A storage cover is also arranged around the middle of the column, and the storage cover faces the slope.

By mixing rough sea cucumber and basket fish in the polyculture tank mainly raising Penaeus monodon, the bottom sludge and water algae in the polyculture tank can be effectively controlled respectively, so as to ensure that the bottom and water body of the polyculture tank can always meet the requirements of monodon The growth conditions of prawns, the polyculture of this model provides a better economical farming model. The roof provides a relatively stable underwater environment for rough sea cucumbers, and at the same time provides a certain shading effect, providing a shade-loving environment for rough sea cucumbers during the growth process. The storage cover can store residual bait and further provide a shade-loving environment.

The perch piles are divided into the first perch pile and the second perch pile. The first perch pile is installed obliquely on the slope, and the second perch pile is vertically arranged on the bottom of the polyculture pond. The first perch pile and the second perch pile are connected to each other. They are arranged on the edge of the polyculture pond and form a circle respectively, and a ring ditch is arranged on the inner side of the circle formed by a plurality of second perching piles. Emergent plants are planted in the ring ditch.

Due to the patrolling characteristics of Penaeus monodon, feeding is basically sprinkled along the edge of the polyculture tank, so that Penaeus monodon and basket fish have more time to move around the edge of the polyculture pond, and residual bait and fish and shrimp manure are more concentrated on the edge. In this way, the residual bait and fish and shrimp manure will gradually slide down the slope to the perch pile, and the rough sea cucumbers at the perch pile can eat the residual bait, etc., and the excess dirt will be further drawn into the ring ditch.

The setting of perching piles can provide a good habitat environment for rough sea cucumbers. The rings formed by the first perching pile and the second perching pile respectively block the flow of sludge from the edge of the polyculture tank to the middle of the polyculture pond, ensuring that residual bait, sewage The diffusion of mud, etc. can be controlled within an effective range; further, the emergent plants in the ring ditch and the ring ditch can well isolate the polyculture pond into two areas, the middle and the surrounding areas, and the emergent plants can use the water at the bottom of the ring ditch The deposited sludge grows, and at the same time, the sludge is stabilized by the roots of emergent plants. Regular cleaning of the ring ditch can effectively remove the sludge in the polyculture tank.

There is a layer of fine sand layer on the bottom of the polyculture pond, and no fine sand layer is laid in the ring ditch. Because the rough sea cucumber likes the sandy environment, no sand layer is set in the ring ditch, which can prevent the rough sea cucumber from going to the ring ditch and the ring ditch. Migration, this can ensure to a certain extent that most rough sea cucumbers only move around the edge of the polyculture pond, which is convenient for daily management and later capture.

The cylinder of the perching stake is inserted to a certain depth in the sediment at the bottom of the polyculture tank.

A polyculture method carried out in a polyculture pond. The rough sea cucumbers are stocked in the storage cover, and the monodon prawns and the basket fish are mixed in the water of the polyculture at the same time, and the bait of the monodon prawns is fed regularly. The bottom of the slope at the edge of the polyculture tank is splashed.
