Description
The technical field is as follows:
the invention belongs to the technical field of aquaculture, and particularly relates to a method for accurately putting shrimp larvae into a shrimp and crab polyculture pond.
Background art:
the successful key of the shrimp and crab mixed culture mode lies in the accurate putting of shrimp larvae, if the putting quantity is too large, the survival rate of river crabs can be reduced, and if the putting quantity is too small, the yield of crayfishes can be reduced. And the accurate control of the number of shrimps in the crab pond is to control the shrimps in the original pond on one hand and ensure the survival rate of the thrown shrimp fries on the other hand.
The shrimp larvae are directly put in the crab pond, the survival rate of the shrimp larvae is not guaranteed, the shrimp larvae are put in the mode of putting the egg-carrying shrimps, the survival rate of the shrimps can be effectively improved, and the number of the shrimps is guaranteed. The survival rate of the egg-carrying shrimps is guaranteed, and the transportation and putting method is particularly key. In addition, in the traditional transportation method, too many egg-carrying Procambrus clarkii are placed in a single transportation box, so that the egg-carrying Procambrus clarkii are too crowded and collide seriously with eggs, and the death rate of the egg seedlings is higher;
the invention content is as follows:
the invention aims to solve the problems and provide a method for accurately putting young shrimps in a shrimp and crab polyculture pond.
In order to solve the above problems, the present invention provides a technical solution:
a method for accurately putting young shrimps in a shrimp and crab polyculture pond comprises the following measures:
(1) The method for fully removing the shrimps in the original pond comprises the following steps:
t1, after the crab catching is finished every year and before water is added for transplanting aquatic weeds, respectively and fully cleaning the pond with 80 kg/mu of quicklime to remove and kill the crayfishes in the original pond;
(2) The method for preventing the exogenous shrimps from entering the crab pond comprises the following steps:
t1, when water enters the crab pond, filtering the water by using a 60-mesh nylon net;
t2, when aquatic weeds are planted in the crab pond, the lobsters carried in the weeds need to be cleaned;
(3) Putting the shrimp larvae:
t1, directly putting the shrimp larvae in an oviform mode;
(4) The transportation method comprises the following steps:
t1, before catching and collecting the oozing procambarus clarkia, preparing a proper amount of waterweed and a special oozing procambarus clarkia transport box according to the demand, flatly spreading the waterweed with the thickness of 2-3cm at the bottom of the transport box, and adding water to the waterweed with the depth of 1cm for later use;
t2, after the laying procambarus clarkia enters the shrimp catching cage, lightly taking the laying procambarus clarkia out of the shrimp catching cage, placing 6 procambarus clarkia/box on the waterweeds at the bottom of the transport box, then, paving the waterweeds on the laying procambarus clarkia, covering the waterweeds with the thickness of 1cm, simultaneously, tightly covering the cover of the transport box, and transferring the transport box into the transport box after all the required laying procambarus clarkia is loaded into the special transport box;
(5) The releasing method comprises the following steps:
t1, after transporting the egg-carrying procambarus clarkii to a target crab pond, putting the procambarus clarkii according to 2 boxes/mu (12 boxes/mu);
t2, seedling releasing specifically comprises the following steps: and (3) taking out the special egg-carrying shrimp transport box from the transport box, placing the transport box in a crab pond water body, opening a cover to expose the water surface, taking out a proper amount of crab pond water body, slightly splashing the transport box egg-carrying shrimps and waterweeds, and taking out the egg-carrying shrimps or allowing the egg-carrying shrimps to freely climb into a culture water body after 4-5 minutes, thereby realizing high survival rate fry release.
The transportation box is used as a preferable technical scheme of the invention, and the box body is made of polyvinyl chloride material, and is black, waterproof and light-proof.
As a preferred technical scheme of the invention, the transportation box has the length, width and height of 15cm, 10cm and 8cm respectively, and the space of the transportation box is just suitable for subpackaging 6 egg-carrying shrimps.
The transportation box is used as a preferable technical scheme of the invention, the middle part of the bottom end of the box body is fixedly connected with a vent pipe, and the top of the vent pipe is provided with a vent hole.
The transportation box is used as a preferable technical scheme of the invention, the length of the vent pipe of the box body is 4cm, and the aperture of the vent hole is 2mm.
The transportation box is used as a preferred technical scheme of the invention, the upper opening of the box body and the four edges of the lower edge of the top cover are provided with primary and secondary sealing buckles, and the top cover is connected with the box body through the primary and secondary buckles.
The invention has the beneficial effects that: (1) effectively removing shrimps in an original pond; (2) stopping lobsters brought by river waterweeds at a water source; (3) The survival rate of parent shrimps and shrimp eggs is guaranteed while the egg-carrying procambarus clarkia can be transported for a long time, and farmers can be helped to improve the survival rate of fry transportation and precise fry release. The concrete points are as follows: the transportation box is suitable in size, and one box of egg-carrying shrimps is placed in each mu of river crab culture pond, so that accurate seedling placing is realized; the internal space of the transport box is proper, the egg-carrying shrimps placed in the transport box have no fighting space and are not crowded, and a large amount of eggs falling of fighting are avoided due to mutual collision; the lobsters can be quiet in the dark environment, and the crayfishes can be effectively prevented from crawling, fighting and falling eggs; aquatic plants and water are put into the transportation box, so that the ovigerous shrimps and the ovigerous seedlings can be protected in the transportation process, the humidity in the transportation box is kept, and the survival rate of the ovigerous shrimps and the ovigerous seedlings is improved; the air holes in the transport box can enhance air circulation, so that the death of parent shrimps and brooding seedlings caused by oxygen deficiency is avoided; due to the unique structures and positions of the vent pipes and the vent holes, water in the box can be effectively prevented from flowing out due to the fact that the transport box is reversed in the transport process, and the moist environment in the transport box is further kept so as to improve the survival rate of the egg-carrying shrimps; (4) In the operation of putting the fries, the time for the egg-carrying parent shrimps and the shrimp eggs to adapt to the culture water is reserved, the stress is reduced, and the survival rate of the egg-carrying shrimps and the egg-carrying fries is improved. (5) The shrimp fishing, transporting and releasing processes only have one shrimp dividing process, so that egg falling caused by manual operation is effectively reduced.
