The utility model proposes a kind of drawing device for collecting seawater fish embryonated egg.

It refer to shown in Fig. 1 and Fig. 2, the collection seawater fish embryonated egg draws in the net to fill in the utility model embodiment Put, including one draws in the net 110,110 middle parts of drawing in the net are provided with an opening 111, and the opening 111 is deposited by a wing 120 with one Water storage ovum container 130 connects.

By setting an opening 111 drawing in the net 110 middle parts, the opening 111 passes through wing 120 and stores up ovum appearance with water Device 130 connects, and when collecting embryonated egg using the drawing device, operating personnel, only need to be in spawning pond or spawning without lower water operation Barre 140 is held on net cage both sides, and the float 150 drawn in the net according to the regulation of the spawning pond depth of water on 110 is on the hook 141 of barre 140 Position, barre 140 is pressed close to pool wall and drawn in the net, you can embryonated egg in spawning pond is all collected into the water of drawing device Store up in ovum container 130, because water storage ovum container 130 is water-tight, so as to avoid the embryonated egg of collection in a reservoir because back and forth Draw in the net and extrude impaired.The device have it is reasonable in design, be not damaged from water operation, embryonated egg, it is simple in construction, that cost is cheap etc. is all More advantages.

Preferably, 110 both sides of drawing in the net respectively are set while cover, and barre 140 is provided with the side set.It is easy to poultry feeders to enter Row draw in the net operation collect embryonated egg.

Preferably, the barre 140 be provided with the scale that sounds the depth of the water and suspension draw in the net 110 hook 141.

Preferably, 110 top edges that draw in the net are provided with float 150, and 110 lower edges that draw in the net are provided with sinker 160.It is easy to Expansion draws in the net 110, preferably collects embryonated egg.

Preferably, it is described draw in the net 110 and the mesh of wing 120 be 90-160 mesh.

Preferably, the opening 111 for drawing in the net 110 middle parts is circle.But not limited to this.

Preferably, the bottom of the water storage ovum container 130 away from described one end of wing 120 is provided with a closeable discharge Mouth 131, in order to the discharge of fish-egg.

Preferably, the water storage ovum container 130 is detachably connected with the wing 120.After ovum collecting of being fertilized is complete, directly Remove water storage ovum container 130, you can embryonated egg is subjected to subsequent treatment.

Specifically used step：Seawater fish parent population pulls parent population out after spawning pond spawning and fertilization, and use is of the present utility model Drawing device carries out ovum collecting operation of being fertilized, barre 140 is inserted draw in the net 110 both ends side cover in and deploy to draw in the net 110, be divided to two People operates, and a people respectively holds a station of barre 140 on spawning pond both sides, and drawing in the net float 150 on 110 according to the regulation of the spawning pond depth of water exists Position on barre 140, hang on the hook 141 of corresponding scale, barre 140 presses close to pool wall, is slowly drawn from one end of spawning pond To the other end, avoid drawing in the net it is too fast cause embryonated egg to be damaged, draw in the net to after the other end, it is slow that barre 140 is close to pool wall by two people Turn and draw in the net 110 directions, typically to draw in the net back and forth 2 times, you can the embryonated egg in spawning pond is collected into water storage ovum container substantially In 130, operating barre 140 afterwards will draw in the net 110 to carry away the water surface, water storage ovum container 130 be removed, so as to complete the receipts of embryonated egg Collection.
