Abstract

PURPOSE:To realize the artificial hatching and culture of lobster and to enable the shipping of lobsters having definite specifications at a low cost by using a specific apparatus. CONSTITUTION:A stainless steel mesh 2 containing a parent lobster is put into a transparent water tank 1 provided with a seawater circulation apparatus. Separately, cedar leaves 3 are immersed in seawater to collect planktons on the leaves and the leaves 3 holding the planktons attached to the leaves are put into the transparent tank 1. The lobster is fed with a feed prepared by crushing fillet of mackerel and waste water of washed rice with a mixer throughout the stages of roe and larva. When the larva is colored and grown to young lobster, it is transferred to a fish cage for culture to complete the objective artificial hatching.

ることが可能となる。Description [0001] [Industrial field of use] The present invention relates to a method and an apparatus for artificial hatching of lobsters. [0002] [Prior Art] Conventionally, many research institutions and fisheries personnel are conducting research on artificial hatching of spiny lobster, but it is not yet successful. This is because the lobster egg is a fertilized egg, and artificially laying the egg will give stress to the parent shrimp and increase the number of immature eggs, and it will not be able to endure the subsequent repeated molting. Therefore, at present, it is the current situation to capture and cultivate lobsters that have grown to some extent in the natural sea. [0003] [Problems to be solved by the invention] An integrated production method of artificial shrimp from artificial hatching to aquaculture, which many researchers cannot do before. [0004] [Means for Solving the Problems] The method will now be described as follows. 1 For the management and spawning of the shrimp caught from the natural sea, a stainless steel metal rope of a size that allows the shrimp to slowly enter the transparent water tank (1) equipped with a natural seawater circulation device installed indoors on land to avoid irritation. Put the shrimp in (2) before inserting. This is because (a) to prevent stress on the shrimp (b) to prevent immature eggs when the shrimp lay eggs (c) to be observed well when the larvae molt. 2 The reason why cedar leaves are put in the aquarium is that there is no other object that is so good as a plankton house, and it is a fine gem of a fauna and flora. There is no suitable one. This is (a) suitable for larvae of lobsters and suitable for the development of plankton, allowing larvae and plankton to live together. (B) By supplementing or replacing the cedar leaves that had been placed in the sea for about a month in the aquarium for the attachment of plankton, plankton can be constantly replenished as food for larvae. (C) As an artificial bait, mackerel fillets and rice bran juice are stirred like water with a mixer and poured into cedar leaves so that the seawater in the aquarium does not become cloudy. 3. As for molting and growth, the behavior of molting takes place every week, so it transforms into glass shrimp in about 300 days while molting, and the glass shrimp becomes colored and shrimp in one week. It begins to color from the antennae and becomes red. 4 Regarding the aquaculture equipment for juvenile shrimp, if the juvenile shrimp becomes colored and becomes a juvenile shrimp, move it to the aquarium (4) with more room. Then count. In the water tank, make a shrimp sumika (5) with a combination of concrete blocks and put cedar leaves. This is because (ii) lobster prefers new places and dark places, which is good for coloring and also for relieving stress. (B) Ise shrimp is more susceptible to stress than humans,
The space created by the combination of concrete blocks is a well-habited house because it dislikes the large family system. (C) By adding cedar leaves, it is possible to secure a dark place at the same time as the plankton's house and feed in the dark. Also, this device is equipped with a seawater circulation device,
Further, an ozone generator may be attached. [Examples] [Example] It takes about 10 months from the spawning to the larval stage, and after the larval stage, the growth is considerably accelerated, and thereafter, 2 to
Body length about 6-7 cm in 3 months, weight about 300-5 in 2 years
It grew to a weight of about 00 grams, a weight of about 600 grams in 3 years, and a weight of about 1.2 to 1.5 kilograms in 4 to 5 years. [0006] [Effect of the invention] In the current aquaculture and cultivated fisheries,
Although aquaculture by artificial hatching of various high-class seafood has been realized, it cannot be solved yet, and the lobster was a flower of high price. By utilizing cedar leaves as a natural habitat for plankton and at the same time as an optimal habitat for larvae of lobster, artificial hatching and aquaculture of lobster, which has been impossible until now, could be realized. This artificial hatching method makes it possible to mass-produce and ship the shrimp all year round at a low price with a certain standard.
