Abstract
The invention provides a method for acquiring and hatching fertilized ova of fish. The method comprises the following steps of: collecting the fertilized ova of the fish by using an attachment in a parent fish pond; moving the attachment to a hatching pond, and hatching, wherein during collection, a thin film is covered on the attachment first to form an acquisition matter, and the acquisition matter then is put into the parent fish pond in a mode that the surface, which has the thin film, of the acquisition matter is upwards, and after parent fish finish spawning, the acquisition matter is fished out of the parent fish pond and is moved to a container with water quickly, and the thin film is stripped; and moving the thin film [14] to the hatching pond [11] with water, and hatching. Compared with the prior art, the method has the advantages that: the fertilized ova are acquired by a layer of thin film, so the thin film is soft, small in volume, light, thin and convenient to move, and the damage of the fertilized ova due to the collision of the thin film is avoided. Simultaneously, after the thin film is stripped on a plate object, and the plate object can be used again immediately by covering the thin film. Therefore, the acquisition cost and transportation cost of the fertilized ova are reduced simultaneously.
Description
Technical field

Said substrate is that thickness is the transparent or semitransparent thin plate of 4 ~ 6mm; Said film is that thickness is that 0.8 ~ 1.2mm is a transparent plastic film.
The collection of fish oosperm provided by the invention and hatching m gather and to be layered on collection plate at the bottom of the parent fish pond before the fertilized egg or to be suspended in the water of parent fish pond, and the attitude of collection plate is to tilt or level.Select to be placed on collection plate at the bottom of the pond or to be suspended in the water according to the spawning habit of parent population.
The collection of fish oosperm provided by the invention and hatching m, the one side that is stained with fertilized egg during hatching on the film is communicated with Chi Shui, selects to use in following three kinds of modes:
On sticking to film at the bottom of the pool wall of hatchery or the pond;
Film is sticked to other carriers that are arranged in the hatchery, on plate, net sheet, post etc.;
With thin film suspending in the water of hatchery.
Said with the method for thin film suspending in the water of hatchery, be to constitute a hanger bar or a movement weight rod with two above clips and a pole earlier, again will be on the relative both sides of every film respectively folder go up hanger bar and movement weight rod, on movement weight rod, hang up weight at last and tie up to make on the hanger bar under the film open configuration and be suspended in the water with rope.
The collection of fish oosperm provided by the invention and hatching m, when parent fish pond and hatchery close together, to gather thing and directly move on to the hatchery from parent fish pond, and carry out film and separate with attachment in the hatchery, it is exactly the hatchery that promptly said another has the container of water.
The collection of fish oosperm provided by the invention and hatching m when parent fish pond and hatchery distance more maybe needs the vanning transportation, strip in water behind the film earlier with the water plastic bag sealing of packing into, with convenient carrying transportation.Preferably one bag of film and oxygenation in bag when sealing during pack is to ensure the quality of products.
