Description

Technical Field [0001] The present invention relates to a biofloat-

In particular, the present invention relates to a method for producing a seedling of a barnacle, which comprises feeding a biofloat to a larvae feeding tank and a bioflag feeding water tank to produce a seedling of the barnacle, And to utilize it as a material for house (habitat).

As leisure opportunities have increased in recent years, the leisure population continues to increase. At the same time as the leisure population is rising, the consumption of lobsters, which are one of the consumables and used as bait for sea fishing, is also increasing rapidly.

Domestic lugwurst market is estimated to be about 50 billion won, and 90% of lugworts produced in Korea are imported and distributed.

Lagoons are used as fishing bait, and some fishermen have tried to breed lagoons at the time when the demand for high quality bait such as rocky lagoons is steadily increasing, but most fish are not earning big income.

In addition, the species of domestic species is a necessary time for the resource creation and preservation of the lagoon in the Korean coast.

Some research institutes, schools, and companies have been studying the technology to produce seedlings. However, stable mass seed production for industrialization has not yet been made.

The survival rate of the larvae is influenced by various physico - chemical environmental factors, food, and pirate creatures, and the mortality rate is high . During this period, the insects infiltrate into the matrix and form stable habitats, resulting in a stable survival rate.

The insects grow to a size that can be sold as an adult after about 22 months. This is called the positive production period. The survival rate during the positive production period is about 80%, which is very high. Therefore, it is necessary to develop a technology that can increase the survival rate of the seedling production period with high mortality rate during the entire production period.

Biofloat technology is a system in which ammonia generated in aquaculture is removed by three routes: phytoplankton, nitrifying bacteria, and tagging bacteria. Biofloat technology is a group of plants dominated by photosynthetic and autotrophic microorganisms, , It is a technology to remove ammonia and nitrite nitrogen which are generated in aquaculture activity and exhibit harmful effect more efficiently and utilize it for biological production.

The most representative features and advantages of BioFlag technology can be divided into three categories,

First, since the breeding water in the aquaculture facility is not exchanged or minimized, environmental pollution caused by contaminated effluent water can be greatly reduced, and the cause of infectious diseases transmitted through the breeding water can be prevented from origin.

Secondly, it can be used to feed Flack and to form a habitat by aquaculture, so it can improve feed efficiency and increase the density, growth and survival rate of aquatic organisms, thereby maximizing aquaculture productivity.

Third, it can remove chemical harmful factors such as ammonia and nitrite more effectively than self - nutrition, which is more convenient and efficient than the conventional management of aquaculture water quality.

Among the techniques for producing seedling seedlings, Korean Patent No. 10-1508055 has proposed a water treatment tank for bioprocesses using biological skimmers (hereinafter, referred to as a pre-registered invention).

The present invention relates to a water tank body comprising a bottom portion having an open top and a predetermined area, and a water tank outer wall having a polygonal shape; The water supply pipe is connected to the water tank main body starting from the water collection tank, and the bottom water tank is connected to the water tank main body The discharged water is connected to the auxiliary water pipe and the drain pipe, and the water discharged from the auxiliary water tank is connected to the collection pipe and the plurality of pipes.

The above-mentioned line-registration invention uses biofloat breeding water discharged from a fish culture tank of a water tank body as a feed for ancillary aquaculture by discharging it into a water tank for cultivating tidal flora biology, It is possible to cultivate tidal flat creatures with rearing water rich in surplus feeds, organic matter, and minerals while controlling the concentration to the desired concentration. In addition to increasing the added value by compounding fish and tidal flat creatures at the same time, It is possible to save a large amount of money, thereby providing a profitable high-value-added form effect.

Korea Patent No. 10-1508055

The cause of death in the seedling production period can be roughly classified into four kinds.

First, it is difficult to maintain the water quality of the lagoon in the existing lagoon aquaculture system. Larvae are so small that they must be observed under a microscope, which is very difficult to distinguish because of their temperament. Therefore, it is difficult to grasp the biomass, and it is difficult to grasp the precise survival object, and the feed supply can not be determined properly.

Second, since the amount of feed can not be determined properly, it is difficult to confirm whether the amount of feed is small or large. The remaining feed in the breeding stock is the main cause of contamination of water quality and substrate, leading to mass mortality.

Third, there is a difficulty in creating a substrate. It is difficult to treat pearl, sand and masato at the same time as a breeding substrate. Cleaning, disinfection and disinfection, and the substrate characteristics required for each stage of growth are different. Therefore, it is troublesome to consider the composition of the substrate in each stage of breeding.

Fourth, in the process of catching earthworms that live in the substrate during pre-sale or harvesting, they are cut off or the deaths due to wounds are high. It takes a lot of time to catch. Therefore, it is necessary to develop a small-scale cell type breeding container for the pre-sale or batch production.

Accordingly, the present invention aims to contribute to productivity improvement by inducing rapid growth of the seedlings by increasing the yield of the seedlings by using Biofloc.

It is an object of the present invention to provide a bioflocculation method and a bioflocculation method of a bioflocculation method, comprising: a mixing chamber for mixing biofloat and seawater into bioflocculation water; a breeding water supply unit for discharging the bioflocculation water from the mixing chamber to the outside; An air supply unit including an air generation chamber provided to generate air to be supplied together with water and an air induction pipe for discharging the generated air to the outside of the air generation chamber; A tank having a storage chamber and a circulation pump member for circulating a biofloat breeding water drained or drained from the bioflocculation tank stored in the tank to a storage chamber of the tank, And the number of breeding birds that feed the lagoons, larvae, biofloat breeding water, and air into the receiving chamber of the container And a drain line member for discharging the biofloat breeding water filled in the storage chamber of the container to the outside of the storage chamber when the biofloack breeding water is supplied at an ideal height, A feed frame for feeding the biofloat breeding water and air to the breeding water supply member of the container to be loaded, and a supply line for supplying the biofloat breeding water and air to the breeding water supply member of the container to be loaded, The present invention is not limited to this.
