Abstract
Description
The present invention relates to artificial fishes for sea cucumbers, and more particularly, to artificial fishes for sea cucumbers which are provided so that sea cucumbers can live in natural conditions.
The sea cucumbers belonging to the deep sea cucumber river habitat mainly live on the bottom of the tidal flat of the intertidal zone of about 20m or on the coastal reefs and gravel.
The wild sea cucumbers are caught mainly by diving fishermen and village fishermen in April to June.
The annual production of sea cucumbers in Korea was more than 3,000 tons in 1980, but decreased to 2,000 tons in 1990 and to 1,000 tons in the 2000s and then to 2,900 tons again in 2007. However, since 2009, the production of sea cucumber has been on a declining trend.
The sea cucumbers are highly valued by the global nutrition report, and the prices formed at home and abroad are also very high. Therefore, the government recently selected 10 strategic varieties for the mass export of the Central China zone, and is planning to achieve a $ 10 billion export by 2020. As a result, various methods have been tried for the cultivation of sea cucumber, but the cultivation technique such as seedling production is not yet confirmed, and cultivation is difficult due to insufficient development of good seedling.
However, the sea cucumber aquaculture industry is very likely to rapidly develop into a promising industry even in the difficulties of other cultivars. The reason is that juveniles weighing 2.0g to 2.5g are mainly fed with adherent microalgae, and adults are consumed with pearl of the seabed so that the organic and protozoa, crustaceans, molluscs, It is advantageous that feed cost is low because it consumes fine plants and animals such as fish bodies. In addition, consumption of sea cucumber in Korea and China is continuously increasing year by year, but natural sea cucumber alone can not meet the demand. Especially, when the temperature of the water is higher than 24 ℃ in summer, it can not be taken at this time because of the summer sleep. In other words, the sea cucumbers that have spawned from May to June hid in the dark places such as under rocks and rocks, or they move to the sea far from the land. After that, when the water temperature is above 25 ℃, it enters the fasting state and digests the digestive tract and stops exercising at all. In this way, the sea cucumber does not eat food, it shrinks the body and there is no activity. When water temperature falls, it starts activity again.
There is no standardized model for the method of the sea cucumber culture yet, and no large scale test has been attempted. It is mainly done in the form of sperm, festival and aquarium.
Most of the sea cucumbers are moved to other waters because of the lack of proper habitat for sea cucumbers that are released or sprayed in the sea. Especially, when young sea cucumbers are sprayed in the sea, more than 50% of released sea cucumbers are killed by food of predatory fishes, resulting in a very low survival rate.
On the other hand, in the case of culturing sea cucumbers in the aquaculture tank, the first water depth of 300m to 500m from the coast is required to be raised by installing a water channel in the 18m sea area and bringing the sea water to the aquarium. You can not cultivate sea cucumbers at optimal conditions.
Disclosure of Invention Technical Problem [8] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide seeds of young sea cucumbers by discharging seeds of sea cucumbers to the sea floor of natural fishing grounds and seedling farms.
The present invention also provides an artificial fish for sea cucumber which can reduce the rate of migration of sea cucumber and prevent the released sea cucumber from being killed by the food of carnivorous fishes, thereby increasing the survival rate.
It is also intended to provide artificial fish seaweed for sea cucumbers which can be easily cultured in the summer of high temperature and low temperature in winter, and can stably produce sea cucumbers under environmental conditions similar to natural conditions, thereby increasing the income of fishermen.
In order to accomplish the above object, according to an embodiment of the present invention, there is provided an artificial fish for the sea cucumber which comprises a frame body forming a plurality of openings, a space formed by a frame structure, At least one undergarment provided to enable the sea cucumber to undergo summer, and at least one sextant provided at the upper part of the undergarment so that the sea cucumber can inhabit and grow.
In a preferred embodiment, the bottom surface is formed in a tubular shape having a polygonal side cross-section and a longitudinal direction and forms at least one bottom surface opening opened in the longitudinal wall surface, And the like.
In a preferred embodiment of the present invention, the plurality of openings formed in the frame body are opposed to the bottom openings formed on both sides of the bottom wall and are opposed to the one side wall and the other side wall of the frame body so as to communicate with the inside of the bottom frame, And at least a pair of first openings.
In a preferred embodiment, the bottom surface includes a plurality of layers formed in a stacked form in which a plurality of layers intersect each other.
In a preferred embodiment, the carcass is a polygonal side surface having a bottom open, formed to have a longitudinal direction, and forming at least one sextuple opening in the longitudinal wall surface, And a long-side opening portion is formed.
In a preferred embodiment, the plurality of openings formed in the frame body are opposed to the one or more sidewall openings formed on both sides of the frame and communicate with the inside of the frame, And at least a pair of second openings.
In a preferred embodiment, when the plurality of sprouts are provided, the sprouts are spaced left and right from the top of the bottom spine.
In a preferred embodiment of the present invention, at least one of the frame, the bottom surface, and the right and left surfaces includes a surface of the wall surface formed in a concavo-convex shape.
As described above, according to the present invention, it is possible to provide seedlings of juvenile sea cucumbers by dropping artificial fish seeds for sea cucumbers on the seabed so as to provide suitable habitat for growing the sprayed sea cucumber.
Also, it is possible to provide an artificial fish for sea cucumber which can reduce the rate of movement of sea cucumber and prevent the released sea cucumber from being killed by food of predatory fishes, thereby increasing the survival rate.
In addition, there is an effect that it is easy to cultivate by providing a proper habitat of the summer high temperature and low water temperature in the winter, and the sea cucumbers can be stably produced under the environmental conditions similar to the natural state, thereby increasing the income of the fishermen.
