Embodiment
With the following Examples the utility model is further described.
A kind of rivers fish-egg as shown in Figure 1, larva and juvenile quantitative collection device, comprise fish-egg, larva and juvenile gather net 1, fish-egg, larva and juvenile collecting vessel 2, static line 3, flowmeter 4, flotation gear 5 and the head rope 6.Entrance and the described head rope 6 of described fish-egg, larva and juvenile collection net 1 are affixed.Described fish-egg, larva and juvenile gather net 1 entirety and are extremely exported in cross section the conical hopper shape shunk gradually by entrance, can effectively collect fish-egg, larva and juvenile; The mesh number that described fish-egg, larva and juvenile gather net 1 is 30 orders, the long 2.5m of body, had both avoided fish-egg, larva and juvenile is escaped from net, and it also avoid and be subject to excessive water flow impact pressure.
Described fish-egg, larva and juvenile collecting vessel 2 comprise ladle body and bung 7, and described bung 7 and described ladle body are for being threaded, and described ladle body and described fish-egg, larva and juvenile gather the outlet of net 1.Described fish-egg, larva and juvenile collecting vessel 2 are for be made up of cylindrical hard PVC pipe, and length is 30cm, and circular base external diameter is 110mm.During collecting sample, described bung 7 is connected with ladle body is airtight; After sampling terminates, described bung 7 can be turned on, take out fish-egg, larva and juvenile sample.
One end of described static line 3 is connected in the described head rope 6 by 3 bifurcated uniform intervals, and the other end is connected on fishing boat.Described static line 3 is the polypropylene rope of diameter 20mm, and the rope of other suitable material also can be used to substitute.
The circular steel ring of the described head rope 6 to be diameters be 80cm, the round steel of steel ring material therefor to be diameter be 15mm.The described head rope 6 is dismountable three sections of connections, and three sections of connected modes are joinery and its construction and connect.Fig. 1 gives the partial enlarged drawing at mortise-tenon joint A point place, and there are two circular holes at each mortise-tenon joint place, and is connected and fixed with screw and cap nut.Dismountable described head rope 6 makes harvester use and carries more convenient.
Described flotation gear 5 has 2, is connected respectively by rope with the described head rope 6 with described fish-egg, larva and juvenile collecting vessel 2.The plastic bottle of described flotation gear 5 to be volumes be 1.5L, the nylon rope that described flotation gear 5 is 3mm by diameter is connected with the described head rope 6 and described fish-egg, larva and juvenile collecting vessel 2 respectively, by regulating the length of described nylon rope, two described flotation gears 5 is on same horizontal line.The effect of described flotation gear 5 when harvester uses is by the connection with described flotation gear 5, makes harvester be in suspended state, avoids gathering net and sinks to the bottom.Described flotation gear 5 also can be the floating body that the density of other certain volumes is less than water.
Described flowmeter 4 is fixed on the home position of the described head rope 6 by 2 ropes.Described flowmeter 4 is digital flowmeter (horizontal trawlnet), and adopt 5 mechanical counters, two point is connected to the described head rope 6.
Operating process: use the utility model in rivers when different waters collection fish-egg, larva and juvenile sample, harvester each several part is coupled together, and with described static line 3, harvester is bundled in the afterbody of fishing boat, fishing boat adverse current is advanced; Then be placed in water by the harvester connected, fishing boat pulls harvester to start to gather fish-egg, larva and juvenile sample; The sample collection time is generally each 15 minutes, and the long meeting of acquisition time causes damage and the distortion of fish-egg, larva and juvenile sample; After each sampling terminates, fishing boat is stopped advancing, pull-up harvester, read and record the data of described flowmeter 4, then described bung 7 is turned on, pour out the sample of collection, collecting by filtration fish-egg, larva and juvenile sample, the fish-egg of collection, larva and juvenile sample are put into other sampling bottles, preserve with corresponding biological organization sample fixer (the neutral formalin fixer, neutral alcohol fixer etc. of 5%) is fixing, sampling bottle is write the information such as collecting location (coordinate), time.Then the sample collection of next round is carried out.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
