Labor-saving water-generating fertilized egg and floating young child collecting method and system thereof

The invention relates to a water-generating fertilized egg and a floating young-age collection method and a system thereof, in particular to a labor-saving water-generating fertilized egg and a floating young-age collection method and a system thereof.

More than 80% of the fish produced by marine fish are floating, and all the fish (including the light and sea water) produce the young (the larvae) which are floating, and the marine invertebrates are mostly young. Part of it is floating, and the aquatic species of light and seawater zooplankton are all planktonic. Generally, the method of collecting floating pelagic eggs or water-generating animals in artificial water flow fields or natural water flow fields is one. The net body is collected on the surface of the water or is provided with an overflow port. The above collection method often causes mechanical damage to the fertilized egg or younger to reduce the hatching rate of the fertilized egg, the survival rate of the seedling and the survival rate of the young child, and the general collecting device is bulky. And the weight is not light (including filtered water), non-2-3 people or more can operate at the same time.

In addition, fish are usually multi-produced fish (that is, for several days in a reproductive season), the above-mentioned method of fishing on the surface of the water, because the net suddenly enters the water to fish for the fertilized egg, it will scare the fish and interfere It subsequently spawns or interferes with the reproduction of broodstock (or broodstock).

Today's technology has not yet developed a collection device or method that can be applied to fish, invertebral and light, seawater zooplankton fertilized eggs and planktonic larvae.

The main object of the present invention is to provide a labor-saving water-producing fertilized egg and a floating young-age collection method and a system thereof, which are extremely labor-saving.

A second object of the present invention is to provide a labor-saving water-producing fertilized egg and a floating young-age collection method and system thereof, which can be applied in various aspects to the collection of fertilized eggs and floating young animals of fish, invertebral and light, seawater zooplankton.

A further object of the present invention is to provide a labor-saving water-producing fertilized egg and a floating young child collecting method and system thereof, which can avoid mechanical damage of fertilized eggs or young animals, thereby improving hatching rate, seedling survival rate and young survival rate of fertilized eggs.

Another object of the present invention is to provide a labor-saving water-producing fertilized egg and a floating young-age collection method and system thereof, which can avoid interference with broodstock egg laying when collecting fertilized eggs.

In order to achieve the above object, the present invention provides a labor-saving water-producing fertilized egg and a floating young child collecting method and system thereof, the method comprising the steps of: a conical mesh having a mesh capable of intercepting water producing fertilized eggs or young One end of the body is suspended and exposed to a water flow field, and a water inlet flowing into one of the water inlets of one end of the net body is connected to the water flow field, the net body is taken out, and the net body is hung on a frame and removed. Storing the contents of the container at one of the other ends of the net body; wherein the net body has a water inlet at the hanging end and a collecting port at the other end, the collecting port is connected and connected to the container, and the hanging manner is The hanging end of the net body is connected to one end of a rope, and the other end of the rope is extended upward and placed on a certain pulley.

Hereinafter, a preferred embodiment of the present invention will be further described with reference to the drawings.
