In addition, the components of the above-mentioned devices are preferably composed of seawater resistant materials.

Hereinafter, a method of artificially producing larvae using an artificial seedling production system having the above configuration will be described.

First, for maturity of caterpillar caterpillars 2 to 4 year old caterpillars are stocked in the caterpillar nurturing tank 110 of the maturity induction device as shown in FIG.

The high mortality rate of larvae larvae is mainly caused by the temperature rise in June-July, which is believed to be due to the formation of anoxic masses, mass reproduction of parasites or predators.

Therefore, in the present invention, in order to preferentially produce early larvae in April-May, where the water quality is stable, the stocking of caterpillars is completed by no later than February, and the temperature of the caterpillar tank 110 is gradually raised to 18-22 ° C. Maintain as to induce the maturity of worms.

Induction of sexual maturity in the present invention can be started in winter or early spring to produce artificial seedlings in April-May or in early autumn to produce artificial seedlings in October.

In the winter season or early spring, induction of sexual maturity is induced by maturation by adjusting the water temperature to 18-22 ° C, and in early autumn, by maturation of water temperature by 22-25 ° C. Induce artificial seedlings.

After inducing winter maturity at 18-22 ° C. for 10-20 days over the winter season, the mature caterpillars are collected and recovered from each caterpillar tank 110 to remove substrates and viscous substances attached to the caterpillars. Into the drawer container 210 of the caterpillar washing device such as 4 (stock) and wash with water.

The drawer container 210 of the caterpillar washing apparatus is heated by the water temperature controller 226, and the seawater sterilized by the ultraviolet sterilizer 227 is filtered through the filter 228, and then the pump 229 and the sea water jet nozzle 223 Flows through.

Pollutants and sea water generated during the caterpillar cleaning process are discharged through the foreign substance discharge network 212 and the foreign substance discharge port 214 of the drawer container 210.

The washed caterpillar is stocked in the spawning induction tank 300 of the spawning induction apparatus as shown in FIG. 6.

Stocked caterpillars can induce spawning by standing for 5-15 days in seawater at 21-25 ° C. For example, when inducing spawning in autumn, spawning is induced by maintaining the temperature at a relatively low water temperature of 20-22 ° C. for 5-15 days.

Therefore, the seawater supplied to the spawning induction tank 300 is heated by the water temperature controller 314 installed in the third seawater inlet pipe 310, sterilized by an ultraviolet sterilizer 315, and then passed through a filter (not shown).

The spawned and fertilized eggs in the spawning induction tank 300 are transferred and stocked to the hatching induction tank 400 through the egg discharge network 304 and the egg transfer pipe 306 by the water flow of the spawning induction tank 300. .

Stocked fertilized eggs are hatched to induce incubation in the hatching induction tank 400 to grow into larvae, at this time, fertilized eggs are discharged to the bottom of the hatching induction tank 400 by the seawater drainage network 420 Particles are discharged so that the ratio of fertilized eggs in the water layer on the sea drainage network 420 is high.

When the fertilized eggs hatch and grow into larvae, the seawater including the larvae of the water layer is discharged to the external larval collection container 412 through the first larval discharge pipe 406 and the second larval discharge pipe 408.

Specifically, in the state in which the valves 319 and 405 are locked, the valve 407 of the first larval discharge pipe 406 is opened, and the seawater of the hatching induction tank 400 is introduced into the first larval discharge pipe 406 to be withdrawn. It is discharged to the larval collection container 412 through the second larval discharge pipe (408).

As described above, the present invention induces the maturation of caterpillar larvae through water temperature control, selects the mature caterpillars, transfers them to the larva washing apparatus, removes microorganisms, pirates and foreign substances, etc. After the eggs are fertilized, the eggs are fertilized and transferred to the hatching induction device by the water stream to incubate. do.

As described above, the present invention collects larvae naturally occurring from caterpillars collected in the existing large space by deliberately producing a large number of larvae in a small area of space compared to conventional natural seedling production. In contrast, the caterpillar can easily recover the worms used for caterpillars, and the caterpillars, eggs and larvae can be managed and managed smoothly by managing the processes of washing, inducing spawning, and hatching of caterpillars in separate small tanks. There is an advantage.

In addition, by inducing maturity of the worms and spawning through the temperature control from the mature caterpillars, larvae are generated in a large amount at a time to facilitate the work for artificial seedling production and labor can be greatly reduced.

In the production of natural seedlings, larvae are usually intermittent for more than 1-2 months, so long-term collection of larvae is required, and the generated larvae settle after a short period of injuries. The production is complete and the collection of larvae is automatic, which is very efficient compared to conventional methods.

In addition, the present invention can arbitrarily control the seed production time and can be produced in good time when the water quality is good, it is possible to produce larvae in any conditions at home and abroad, and further increase the productivity of the tooth.

Although the survival rate during the growth period from larvae to worms was high, it was difficult to exceed 30%, and the survival rate was low as the larvae were produced over a long period. Therefore, even though many larvae were produced, larvae failed to produce larvae. As a result, it is expected that mass production will naturally lead to a high survival rate, enabling high-income aquaculture in the future.
