Abstract
The utility model provides a river fish collection device. Fixed ropes are arranged around net clothes; the front part of the net clothes is sleeved with a support ring, and the rear part thereof is provided with a fish collection device; the net clothes is connected with a support frame with a rope through the support ring; the inside of the support frame is provided with a hydrometic propeller, the bottom thereof is connected with an elliptical type weight, and the upper part thereof is connected with a pulley block and the support; and the device can be used to collect fishes and fish eggs in different water layers, has simple structure, is convenient to be installed and detached, can be used in different types of ships, is simple and flexible to be operated, and convenient to be carried.
Description
Technical field
The utility model relates to the aquatic product fishery scientific domain, specially refers to rivers fry harvester.
Background technology
By rivers and natural water area being in collection, investigation and the research of early stage stage history of life fry; thereby can directly assess the quantity of fish population or the correlation factor that stock number determines to influence fish reproduction colony magnitude of recruitment, this work all has great importance to the fish production and the protection of fish resources.The fry and the fish-egg that are in early development stage are very not weak less than active swimming ability or swimming ability, traditional collecting method is utilize to open to catch netting gear and fish for, be fixed on the bank of rivers, only can gather the fry on top layer, can't fish for lower floor fry in rivers zone line and the water body, influence is to the assessment of fish population quantity.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and is applicable to all kinds of ships, and can gather the harvester of each water layer fry in the rivers.
For achieving the above object, the technical solution of the utility model is:
Support with static line around the etting of rivers fry harvester, the front portion of etting is with bracing ring, the prosopyle of etting is opened, so that current and fry enter, collector is equipped with at the rear portion of etting, be used to collect the fry and the fish-egg that collect, and collector and etting connect, and etting is connected with support frame with rope by bracing ring, and current meter is equipped with in support frame inside, be used to measure the flow velocity of each water layer, the support frame bottom is connected with fish lead, and support frame top is connected with assembly pulley, and assembly pulley is connected with support, pull rope is housed on assembly pulley, is used to control moving of assembly pulley and support frame.The etting of rivers fry harvester uses the strong material of drainage capacity to make.
Good effect of the present utility model is: rivers fry harvester can be used to gather fry, the fish-egg of different water layers, assessment fish that can the science scale of laying eggs.This apparatus structure is simple, easy accessibility, can on different classes of ship, install and use, and simple to operate flexible, be easy to carry, save manpower.
Description of drawings
Fig. 1, rivers fry harvester structural representation.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing 1.
With reference to Fig. 1, support 8 is fixed on the gun wale of institute's use ship, assembly pulley 9 is connected on the support 8, assembly pulley 9 bottoms connect support frame 10, current meter 6 is housed in support frame 10, the bottom of support frame 10 connects fish lead 5, connect the bracing ring 4 of etting 3 front portions with rope, connect the collector 1 at etting 3 rear portions, connect etting 3 static line 2 all around, be exactly collector 1 like this, etting 3, fish lead 5, support frame 10 is as a whole with 9 one-tenth in assembly pulley, loosens pull rope 7, and whole fry harvester is positioned on the river surface, under the effect of assembly pulley 9 and fish lead 5, whole fry harvester is slowly put into river,, device is sunk in the different water layers according to the kind that will gather fry.Fry enters in the etting 3 by the bracing ring 4 of etting 3 front portions together with river, enters at last in the collector 1 at etting 3 rear portions, and river then leaches by etting 3.Current meter 6 writes down the size of river flow velocitys simultaneously.
