Description

Apparatus for collecting larva}

The present invention relates to a larvae collection device, and more particularly to a larvae collection device that can collect the larvae by shelling the shell of the durable egg.

One of the most widely used biological foods for farmed fish is brine shrimp (Artemia salina). Globally, the market for brine shrimp is about 300 billion won as of 2010. Of these, the Korean market, which relies on imports, is between 3 billion and 6 billion won, accounting for 2% to 4% of global consumption.

Since the brine shrimp is in the form of egg-resistant eggs (cysts), it cannot be fed but must be fed through the hatching process. The egg shells that surround the egg have many harmful bacteria such as pathogenic viruses, which may reduce the survival rate of the hatched larvae and greatly affect the health and survival of fish fry. Therefore, it is necessary to remove a shell at the time of incubation of a durable egg. Generally, the hatched larvae and egg shells are separated using a sieve, but there are problems such as egg shells passing through the sieve or larvae not passing through the sieve.

The technical problem to be achieved by the present invention is to provide a larvae collecting device that can collect the larvae by shelling the durable egg shells, or collect the larvae from the mixed liquid mixed with the durable egg shells.

The second container 200 is a collection chamber 210 capable of collecting larvae passing through the larvae passing means 160.

Referring to FIG. 6, a state in which the durable egg 302 is injected for hatching is shown in FIG. 6. That is, the durable egg 302 is put on the water surface of the inflow chamber 110. Since the durable column 302 is a dry state, all will be floating on the water surface. The upper part of the first container 100 is covered with a cover 400 and a bubbler (not shown) is connected to the air supply pipe 102 to supply air to the inflow chamber 110. In FIG. 6, the durable egg 302 has been added, but by incubating in another container, the mixed solution in which the durable egg shell (shell) and the larvae are mixed may be added.

Referring to FIG. 7, a state in which the durable egg subsides after a certain time is shown in FIG. 7. That is, when air is supplied to the inflow chamber 110, the inner column 302 is in contact with water and gradually contains water, and some of the water sinks to the bottom as indicated by the arrow. In addition, due to the first penetrating portion 114, the durable column 302 sinks to the bottom of the inflow chamber 110 and the swimming chamber 120.

Referring to FIG. 8, the hatching starts and the durable egg shell and the larvae are shown in FIG. 8. That is, when hatching begins after 24 hours, for example, the durable shell 304 rises to the surface, and the larvae 306 swim toward the bright place in the direction of the arrow, that is, the collection chamber 210. The floating durable shell 304 rises to the water surface of the inflow chamber 110 and the possessive chambers 120 and 130. Even when the mixed solution containing the larvae and the egg shells into the inflow chamber 110, the shell 304 rises to the surface over time, and the larvae 306 swim toward the bright place in the direction of the arrow.

In other words, as shown in FIG. 8, the larvae 306 are moved from the first possessing chamber 120 to the second possessing chamber 130 due to the first small partition wall 122 installed at a height T2 lower than the water level. Move. Subsequently, the larva 306 moved to the second possessive chamber 130 moves from the second possessed chamber 130 to the third possessed chamber 140 due to the second penetrating portion 134.

Referring to FIG. 9, the hatching is completely completed, and the durable egg shell and the larvae are separated from each other. That is, after a sufficient time has passed after hatching is completed, the larvae 306 are attracted to the light flowing into the larvae passing means 160 and are collected in the collection chamber 210 through the larvae passing means 160. In other words, light flowing from the outside flows into the larvae passing means 160, and the light larvae 306 included in the third possessive chamber 140 are collected in the collection chamber 210. As described above, when the lighting device is further installed on the collection chamber 210, the larvae may be collected well into the collection chamber 210.

In addition, since the durable shell 304 does not pass through the larval passage means 160 is trapped in the inner space of the first container 100 is completely separated. Subsequently, pure larvae 306 that are completely separated from the durable shell 304 may be collected through the larvae exhaust duct 202.
