Abstract:
본 발명은 수상가두리와 함께 설치되어 양식어류의 먹이를 공급토록 한 사료공급장치에 관한 것으로서, 더욱 상세하게는 사료투입관과 사료배출관이 상,하단측에 각각 연결되고 내부에는 부유식 사료가 저장되며 고압가스탱크가 내장형 또는 외장형으로 설치된 사료저장탱크를 해저면에 안착시킨 상태에서, 상기 사료배출관으로부터 가두리그물의 하부측 중심부에 이르기까지 밸브기구를 구비하는 사료분배관과 펌프기구를 구비하는 진공조성관과 밸브기구를 구비하는 해수투입관과 사료공급관을 순차적으로 연결 설치하는 한편, 상기 고압가스탱크의 가스주입밸브를 포함하는 각각의 밸브기구와 펌프기구를 배터리 및 제어기구가 내장된 컨트롤부이와 접속시킴으로서, 사료저장탱크의 내압과 부압(負壓)의 압력차를 이용한 진공조성관으로의 사료투입과, 해수공급에 의한 가두리그물 내부로의 부상식 사료공급이 각각의 밸브기구 및 펌프기구에 의하여 순차적으로 반복 수행될 수 있도록 하고, 사료의 공급 과정에서 발생하는 사료저장탱크의 내압저하를 고압가스탱크로부터 배출되는 공기압에 의하여 보상시킬 수 있도록 하며, 이로 인하여 양식어류의 먹이공급에 가장 적합한 상향 분산식 사료공급을 통하여 양식어류간의 고른 성장을 도모하고, 급이관리에 필요한 비용과 인력 및 사료의 불필요한 낭비를 최소화시킬 수 있도록 한 수상가두리용 내압조정식 수중 상향 사료공급장치에 관한 것이다.
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: 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.
