The present invention relates to an inspecting kit (oligonucleotide microarray) and an inspecting method for rapidly detecting a pathogenic organism of a soft tunic syndrome in Halocynthia roretzi by producing a primer through a probe which is specific to a PCR amplification condition in which a 18S rDNA gene of Azumiobodo hoyamushi causing soft tunic syndrome in Halocynthia roretzi can be identified. Consequently, the Halocynthia roretzi of Azumiobodo hoyamushi which is known as the cause of soft tunic syndrome in Halocynthia roretzi is rapidly detected from seawater or Halocynthia roretzi from the initial symptoms of soft tunic syndrome, so that the inspecting kit and inspecting method are applied to an Azumiobodo hoyamushi soft tunic syndrome forecasting system, and damage can be preemptively prevented.
Abstract:
The present invention relates to an integrated system for treating breeding water from a raising farm, wherein breeding water discharged from a raising water tank of a raising farm can be filtered. More specifically, multiple package-type biofilters having microorganisms culturing filtrates inserted therein are installed in a filtering water tank to be capable of being attached and detached. A sterilizing and vortex precipitating tank is disposed in a position before the filtering water tank, wherein breeding water is sterilized, solids are firstly precipitated, and the solids are secondly and thirdly precipitated by means of a vortex and an ascending and descending water flow. The solids are additionally precipitated in a discharging water tank for discharging final treated water from the filtering water tank. The breeding water can be efficiently treated in an integral and advanced mode. Each of the biofilters is easily separated so that the filtrates can be rapidly and easily washed and replaced. The package-type filtrates separated from the biofilters can be fed in a raising water tank for other marine products, if needed. Accordingly, several sorts of organic materials and culturing microorganisms adhered on the filtrates can be utilized as feeds, and cleaning is performed so that the filtrates can be re-mounted. Even when the organic materials adhered on the package-type filtrates are re-utilized as fertilizers and the like, the package-type filtrates are dipped in fresh water so that desalting can be easily performed. Consequently, filtering functions are improved, and useful components collected during a filtering process can be economically recycled.

Abstract:
The present invention relates to an aquaculture nitrogen removal (ANR) system which newly utilizes a carbon source for denitrifying a land fish farm and manages organic materials and nitrogen in waste water of the fish farm by accumulating nitrifying microorganisms at a high concentration in order to express optimal nitrification. A denitrifying tank for hydrolyzing and nitrifying organic materials in culturing water, which is a reactive tank for removing organic materials and nitrogen generated in the land fish farm, is connected with a nitrifying tank which can accumulate nitrifying microorganisms at a high concentration through a pipe. Particulate and dissolved organic materials in fed water are hydrolyzed in order to be utilized as a carbon source for nitrification, so that the organic materials can be effectively removed. The organic materials are preliminarily removed in subsequent nitrification, so that a low carbon/nitrogen ratio (C/N ratio) is maintained in the nitrifying tank. Accordingly, nitrifying microorganisms can be accumulated at a high concentration, and the ANR system can autonomously and biologically remove nitrogen without injection of an external carbon source.
Abstract:
The present invention relates to a filtering tank for filtering the rearing water discharged from a rearing aquarium. More specifically, the present invention relates to a mesh-type bio-filtering tank. An inflow water path and an outflow water path for the rearing water are formed at the top end of a body casing. The internal space of the body casing is divided into an inflow space and an outflow space by a central separation plate. In each space, multiple pieces of mesh filtering plates equipped with fiber sieves are installed at regular intervals and horizontally with respect to a water flow direction. A funnel plate and a discharge pipe are installed inside the body casing which corresponds to the bottom of the mesh filtering plate so as to precipitate and discharge solids. The solids included in the rearing water are precipitated on the bottom of the filtering tank in order to be collected. Fine solids and organic components included in the rearing water are bonded to the sieves of the mesh filtering plates in order to be used for culturing useful microorganisms. Accordingly, the solid filtration and the microorganism filtration are performed at the same time in one filtering tank. The mesh filtering plates themselves can be inserted in other water tanks for culturing marine organisms so that the organic materials and cultured microorganisms bonded to the sieves can be used as a food for the marine organisms and the mesh filtering plates are thereby cleaned to be re-mounted. Even when the organic materials bonded to the sieves are used as a fertilizer, the desalinization can be performed easily by dipping the mesh filtering plates in fresh water. In the present invention, the filtration efficiency of the filtering tank is improved, and the components collected from the filtering tank can be effectively recycled.
