Abstract
The invention discloses a method for catching procambarus clarkii in batches, which comprises the following steps of enclosing a purse net around a pond opening along a circle of 10-15cm below a water line after a seed shrimp is dug on the bank, separating a finished shrimp culture area from a dug spawning area, enabling the procambarus clarkii not to swim to the culture area after the procambarus clarkii goes out of the hole, raising the water level of a pond according to the shipment requirement of the procambarus clarkii when the temperature is proper, stimulating the procambarus clarkii to go out of the hole, placing a special catching cage beside the purse net of the dug spawning area, placing one catching cage every 10m for collecting the procambarus clarkii, holding two ends of the catching cage by hands to lift the procambarus clarkii from the underwater and to the bank side in a soft horizontal manner, wherein the beneficial effects achieved by the invention comprise: the purse net surrounding the mouth of the pond for one circle can prevent the larval shrimps from swimming back to the adult shrimp culture area, so that the recapture rate of the larval shrimps is improved; in a hole-digging and egg-laying area formed by the purse net, the quantity of the held shrimps in the hole can be limited by controlling the water level; the small shrimp catching cages are selected, and the placing intervals and the placing quantity of the small shrimp catching cages are controlled according to requirements, so that the quantity of caught shrimps.
Description
The technical field is as follows:
the invention belongs to the technical field of procambarus clarkii fishing, and particularly relates to a batch fishing method for procambarus clarkii.
The background art comprises the following steps:
the original crayfish clasping shrimps are common species in inland water areas, are delicious in taste and rich in nutrition, are favored by consumers, are fond of digging holes in breeding seasons, are positioned about 20cm above the water surface of a pond, and can be caught after the original crayfish clasping shrimps go out of the holes. Secondly, the common catching cage is utilized to cause large catching amount at a time, the shrimps are tightly held and seriously drop, and thirdly, when the shrimps are caught from the common catching cage, the shrimps are shaken and poured out, the operation is rough and the dropping is serious. The fishing method of the invention can effectively solve the problems.
The invention content is as follows:
the invention aims to solve the problems that the procambarus clarkii moves back to a culture area after going out of a hole, the quantity of single fishing is too large, the larvae drop seriously in the fishing process and the like, and provides a batch fishing method for the procambarus clarkii.
In order to solve the above problems, the present invention provides a technical solution:
a method for batch catching Procambarus clarkii comprises the following steps:
a1, after the breeding shrimps are punched ashore, a purse net is arranged around the pond mouth of the pond along the position 10-15cm below the water level line to separate a shrimp culture area from a punched egg laying area, so that the shrimps can not swim to the culture area after leaving the holes;
a2, when the temperature is proper, according to the delivery demand of the larval shrimps, raising the water level of the pond and stimulating the larval shrimps to go out of the holes;
a3, placing small shrimp catching cages beside the purse net in the holing and spawning area, and placing one catching cage at intervals of 10 m;
a4, collecting the shrimp catching cage, holding two ends of the shrimp catching cage by hands, lifting the shrimp catching cage from the water gently and horizontally, placing the shrimp catching cage on the shore, taking the shrimps out of the cage one by one from the shrimp feeding openings at two ends, and placing the shrimps in a transport box.
Preferably, in step A1, the seine mesh is a 40-mesh water tank net, the seine has a width of about 80cm, is embedded in the soil for about 20cm, and is exposed to the ground for about 60 cm.
Preferably, in step a1, every 2m stay is provided to support the seine vertically upwards.
Preferably, the stay bar is a hard pipe such as a bamboo pole, a steel pipe or a plastic pipe, and the length of the stay bar is more than 80 cm.
Preferably, the shrimp catching cage is cylindrical, and has a length of 60cm and a diameter of 30 cm.
The beneficial effects of the invention include:
1. the purse net arranged around the pond mouth for one circle can prevent the larval shrimps from swimming back to the adult shrimp culture area, and the recapture rate of the larval shrimps is improved.
2. In the punching and spawning area formed by the purse net, the number of the held shrimps in the hole can be limited by controlling the water level.
3. The placing space and the placing quantity of the small catching cages are controlled according to requirements, so that the quantity of caught shrimps in the catching area is controlled.
4. The small shrimp catching cage is convenient for manually taking shrimps, and can avoid crowding the shrimps and falling the shrimps.
Description of the drawings:
for ease of illustration, the invention is described in detail by the following detailed description and the accompanying drawings.
Fig. 1 is a schematic diagram of a top view of a pond of the present invention;
fig. 2 is a schematic cross-sectional view of a ridge of the present invention;
in the figure: 1. a pond; 2. a purse net; 3. a shrimp catching cage; 4. and (5) punching a hole and laying eggs.
The specific implementation mode is as follows:
the following will clearly and completely describe the technical solutions in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Example one
The procambarus clarkii cultured in the pond can mate in 8 to 9 months in the current year, the procambarus clarkii can completely climb out in 10 months, holes are dug in the ridges above the water surface, after the holes are dug to lay eggs, the procambarus clarkii can surround the ridges for one circle by 10-15cm below the water surface around the ridges of the paddy field, after 1 to 3 months in the next year, water is injected into the paddy field to the digging and spawning area 4 according to the demand of the procambarus clarkii, the procambarus clarkii can climb out of the holes to swim into the water under the stimulation of the water, the procambarus clarkii can be intercepted by the nets at the moment and stay in the digging and spawning area 4, small-sized procambarus clarkii cages are put into the digging and spawning area 4 at intervals according to the demand of the procambarus clarkii, the procambarus clarkii can climb to the spawning area due to the drilling habit of the procambarus clarkii, so that the procambarkii can be harvested, the procambarus clarkii can be checked and collected every 12 hours, the procambarkii can be collected in the collecting cages, can place more when not enough and catch the shrimp cage or increase the holding time, can reach batch catching like this to when getting the shrimp, take out one by one, pour out in whole, can prevent effectively to embrace young shrimp and fall young.
While there have been shown and described what are at present considered to be the fundamental principles of the invention and its essential features and advantages, it will be understood by those skilled in the art that the invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
