Abstract
The utility model relates to a device for observing zoeas of scylla paramamosain. The device comprises a cup body (1) and a handle (2). The cup body (1) is an open container made of transparent materials. The handle (2) is mounted on the cup body (1). The appearance of the cup body (1) is of cylinder shape. The handle (2) is of a circular tube shape. The cup body (1) and the handle (2) are connected through a connecting line (3). The device can be used for observing the development states of the zoeas in a culturing process of the scylla paramamosain, and can catch individuals in different numbers for observation as needed so as to grasp the development states of the zoeas at any time. The device is reasonable and simple in structure, low in cost, convenient to operate and high in practicability.
Description
Technical field
The utility model belongs to mud crab zoea observation technical field of tools, particularly relates to a kind of device of observing the Scylla paramamosain zoea.
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.
In Scylla paramamosain artificial breeding process, need at any time zoea and bait are observed, determine developmental condition, active situation and the young of the young and the density of bait, to formulate the concrete scheme of growing seedlings.Therefore, be necessary to invent a kind of device that can effectively, conveniently observe the Scylla paramamosain zoea, can fish for the young of varying number as required and observe, to grasp the developmental state of the young at any time.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of device of observing the Scylla paramamosain zoea, is used for effectively observing the zoea animation of seedling raising process, can fish for the individuality of varying number as required and observe accurately, easily.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of device of observing the Scylla paramamosain zoea is provided, comprises cup and handle, the open containers of described cup for being made by transparent material; On the described cup handle is housed.
Described cup profile is cylindrical, and the rounded tubulose of described handle is fixed with connecting line between described cup and the handle.
Described cup is made by glass material.
Its volume of described cup is about 250 milliliters.
Described handle is made by polythene material.
The about 1cm of its caliber of described handle, the about 50cm of length.
Described connecting line is the polyethylene material, the central authorities of handle being fixed in cup.
Beneficial effect
The utility model can be used for observing in the Scylla paramamosain seedling raising process developmental condition of zoea, can fish for the individuality of varying number as required observes, to grasp the developmental state of the young at any time, this apparatus structure is reasonable, simple, cost is low, easy to operate, practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
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 device of observing the Scylla paramamosain zoea comprises cup 1 and handle 2, the open containers of described cup 1 for being made by transparent material; On the described cup 1 handle 2 is housed.
Described cup 1 profile is cylindrical, and described handle 2 rounded tubuloses are fixing with connecting line 3 between described cup 1 and the handle 2.
Described cup 1 is made by glass material.
Described cup 1 its volume is about 250 milliliters.
Described handle 2 is made by polythene material.
The about 1cm of described handle 2 its calibers, the about 50cm of length.
Described connecting line 3 is the polyethylene material, the central authorities of handle 2 being fixed in cup 1.
The utility model in use, the personnel of growing seedlings use the right hand to hold handle 2, fish for the zoea of a quantity in nursery pond, block certain light as a setting with left hand, observe.Adopt this device can observe zoea effectively, easily, can select the individuality of varying number to observe as required, thereby offer help for formulating the scheme of growing seedlings.
