Abstract:
The present invention relates to an inspecting kit and an inspecting method using a probe and a primer for inspecting Azumiobodo hoyamushi which are pathogenic protozoa causing a soft tunic syndrome in Halocynthia roretzi. 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 a fodder supplying device installed with a fish culturing holder so as to feed cultured fish. More specifically, while a fodder storing tank for storing a floating-type fodder is settled on the seabed, a fodder feeding pipe and a fodder discharging pipe are respectively connected with the top end and bottom end of the fodder storing tank. At the outlet side of the fodder discharging pipe, a fodder distributing pipe equipped with a valve tool and a vacuum composing pipe equipped with a pump tool are sequentially connected. A seawater feeding pipe equipped with a valve tool is connected with the vacuum composing pipe, and a fodder supplying pipe extended toward the bottom side central part of a holder net is connected with the inlet part of the seawater feeding pipe. The valve tool and pump tool are made to come in contact with a control buoy having a battery and a control tool equipped therein. Accordingly, fodder feeding into the vacuum composing pipe using the pressure difference of the atmospheric pressure and negative pressure and floating-type fodder supplying into the holder net by means of a seawater supply can be sequentially and repeatedly performed by means of the valve tool and pump tool. Bottom-up dispersing-type fodder supplying which is most appropriate when feeding cultured fish is performed, so that the cultured fish can be evenly grown. Moreover, unneeded waste in terms of cost, manpower, and fodder needed for managing feeding can be minimized, and breakdowns and malfunctions of the fodder supplying device caused by waves can be preemptively prevented.
Abstract:
The present invention relates to a device for measuring aquatic organisms capable of measuring aquatic organisms in the water without taking out the corresponding aquatic organisms from water for measurement. According to the present invention, the device is configured to directly measure the aquatic organisms even attached organisms without taking out the same from water so that various aquatic organisms can be conveniently and accurately measured without damage to an underwater environment and aquatic organisms.
Abstract:
PURPOSE: A water tub for culturing abalones is provided to improve the space utilization of a fish farm and the culturing efficiency of abalones and to create an optimal culturing environment. CONSTITUTION: A water tub (10) for culturing abalones comprises a water tub main body (1) in which the top surface thereof is open, a water level control pipe installed on the inner center of the water tub main body, a water inflow chamber (2) installed on the inner periphery of the water tub main body, a water jet pipe (3) which protrudes from one side of the water inflow chamber in parallel with the wall of the water tub main body, and a water supply pipe (4) connected to the water inflow chamber. A hanging protrusion (8) for accumulating feed is formed on the bottom surface of the water tub main body. An attachment prevention protrusion capable of preventing the attachment of abalones is formed in the water level control pipe.
Abstract:
PURPOSE: Zostera capricorni transplanting method and apparatus capable of improving survival rate is provided to fix Zostera capricorni using a flexible biodegradable clip. CONSTITUTION: A Zostera capricorni transplanting apparatus comprises the following: a Zostera capricorni fixing plate(101) including more than one through-hole installed to the longitudinal direction for inserting more than one Zostera capricorni; Zostera capricorni fixing sponges with flexibility installed inside the through-holes; and fixing clips(103) fixing the Zostera capricorni from the lower side of the Zostera capricorni fixing plate. The Zostera capricorni fixing plate is produced with a biodegradable resin or a corrosive steel plate.
Abstract:
PURPOSE: A method for treating Scuticocillates infected in a cultured olive flounder or flatfish(Paralichthys olivaceus) by administering ketoconazole to the olive flounder is provided which can destroy even Scuticocillates infected in the body as well as minimizing the stress on the olive flounder. CONSTITUTION: Ketoconazole is parenterally administered to a cultured olive flounder or flatfish at a dose of 200mg/kg, weight to destroy Scuticocillates infected in the body or to the outside of the flounder after it is dissolved in a phosphate solution.
