Abstract
The utility model relates to a simple tool used for catching scylla paramamosains, which comprises a ferrule (1), a handle (2) and a mesh nest (3), wherein the ferrule (1) adopts a round metal structure; the handle (2) is mounted on the ferrule (1); the handle (2) and the ferrule (1) are in the same plane surface; the mesh nest (3) is mounted at the lower part of the ferrule (1); the mesh nest (3) takes the shape of a circular truncated cone in a surround manner; the upper part of the circular truncated cone formed by the mesh nest (3) in a surrounding manner is greater than the lower part; and the upper part opening of the circular truncated cone is matched with the ferrule (1). The simple tool can be used for effectively catching scylla paramamosains in an aquaculture pond, can selectively catch individuals of different specifications as required, and can also prevent crabs from massacring with each other to cause a loss, thereby improving the breeding efficiency and ensuring personal safety. The simple tool has the advantages that the structure is reasonable and simple; the cost is low; the operation is convenient; and the practicability is strong.
Description
Technical field
The utility model belongs to Scylla paramamosain trap tool technical field, particularly relates to a kind of light instrument that catches Scylla paramamosain.
Background technology
Scylla paramamosain (Scylla paramamosain) is a kind of large-scale carnivore swimming crab, China mainly be distributed in the entrance of Changjiang River and on the south the offshore sea waters, be the traditional marine fishery resources of China and mariculture crab class.Scylla paramamosain has advantages such as build is big, growth is fast, meat flavour deliciousness, favored by raiser and consumer.The Scylla paramamosain aquaculture industry of China mainly is distributed in the southeastern coastal areas, has formed bigger breed scale.
In recent years, the breed annual production of China's Scylla paramamosain is stabilized in more than 100,000 tons always, has kept stable growth momentum.The breeding way of Scylla paramamosain is mainly based on pond culture, and traditional catching mode is that employing ground cage net or the mode that drains Chi Shui catch, and has many limitation.The shortcoming of ground cage net catching mode is that more individuality crowds in narrow and small ground cage net, is easy to cause cut one another's throats, and causes to culture loss.And draining pond water catching mode, its prerequisite is to prepare all individualities are all caught out the pool, but because the crab class is liked burrowing and hidden oneself, also is not easy all to capture.Also there are not at present a kind of effective ways that in breeding process, carry out catching on a small scale Scylla paramamosain that are applicable to.Therefore, be necessary to invent a kind of instrument that can effectively catch the Scylla paramamosain in the cultivating pool, can select to catch the individuality of different size as required, prevent from cutting one another's throats between individuality and guaranteeing personal safety.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of light instrument that catches Scylla paramamosain, be used for effectively catching the Scylla paramamosain of cultivating pool, can select to catch the individuality of different size as required, prevent that the crab class from cutting one another's throats and guarantee personal safety.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of light instrument that catches Scylla paramamosain is provided, comprise lasso, handle and goal-net, described lasso is the circular metal structure, on the described lasso handle is housed, described handle and lasso are in the same plane, under the described lasso goal-net are housed, and described goal-net surrounds a truncated conical shape, the round platform top that described goal-net surrounds is greater than the bottom, and upper opening and lasso match.
Described lasso is made by the circular metal rod, the about 5mm of the diameter of metal bar.
The about 30cm of its diameter of described lasso.
Be connected the about 2cm of handle diameters with welding manner between described handle and the lasso.
Described goal-net adopts nylon material to make, and highly is 35cm.
Its screen frequency of described goal-net is 20 order/inches.
Beneficial effect
The utility model can be used for effectively catching the Scylla paramamosain in the cultivating pool, can select to catch the individuality of different size as required, can prevent that again the crab class from cutting one another's throats and causing damage, culture efficient thereby improve, guarantee personal safety, this tool construction is reasonable, simple, cost is low, easy to operate, practical.

Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, a kind of light instrument that catches Scylla paramamosain, comprise lasso 1, handle 2 and goal-net 3, described lasso 1 is the circular metal structure, on the described lasso 1 handle 2 is housed, and described handle 2 is in the same plane with lasso 1, described lasso is equipped with goal-net 31 time, described goal-net 3 surrounds a truncated conical shape, and the round platform top that described goal-net 3 surrounds is greater than the bottom, and upper opening and lasso 1 match.
Described lasso 1 is made by the circular metal rod, the about 5mm of the diameter of metal bar.
The about 30cm of described lasso 1 its diameter.
Be connected the about 2cm of handle 2 diameters with welding manner between described handle 2 and the lasso 1.
Described goal-net 3 adopts nylon material to make, and highly is 35cm.
Described goal-net 3 its screen frequencies are 20 order/inches.
When the utility model uses, culture personnel hand handle 2, make an inspection tour at the side of a pond, when finding Scylla paramamosain, rapidly with lasso 1 it being fastened, and it is entered in the goal-net 3.Adopt this device can effectively catch Scylla paramamosain in the cultivating pool, can select to catch the individuality of different size as required, prevent that the crab class from cutting one another's throats and causing damage, culture efficient thereby improve, guarantee personal safety.
