Abstract:
본 발명은 육상의 양식장에서 배출된 사육수의 수질을 정화하기 위한 양식장 사육수의 생물여과장치 및 생물여과시스템에 관한 것으로서, 생물여과수조의 내부공간에 수용된 미생물이 증착된 비드에 의하여 사육수에 포함된 유기물이 제거되고, 미생물에 의하여 제거되지 못하는 고형물은 생물여과수조의 일측에 구비된 고형물 분리기로 사육수와 함께 흡입된 이후, 고형물 분리기의 내부에서 고형물은 자연침전되어 소량의 사육수와 함께 생물여과수조의 외부로 반출되어 고형물 농축기에 의하여 농축되고, 고형물이 분리된 여과된 사육수는 고형물 분리기의 내부에서 고형물의 침전방향과는 반대방향으로 흡입되어 생물여과수조의 외부로 반출될 수 있도록 구성되는 양식장 사육수의 생물여과장치 및 생물여과시스템에 관한 것이다. 또한 본 발명은 미생물에 의하여 생물여과된 사육수를 고형물 분리기에 흡입시켜 사육수에 포함된 회분과 같은 고형물을 제거할 수 있는 효과를 얻을 수 있고; 고형물 방류로 인한 수질 오염문제를 해결하는 효과를 얻을 수 있으며; 고형물이 제거된 여과 사육수를 양식장이 재사용하는 경우에도, 무기질 고형물이 재사용 여과 사육수에 거의 포함되지 않기 때문에, 과도한 무기질 고형물의 조성에 의한 양식어 발병 및 폐사를 방지할 수 있는 효과를 얻을 수 있다.
Abstract:
The present invention relates to an indoor system for inspecting marine products, wherein the impact of a sea environment on several sorts of marine organisms can be experimented and inspected indoors. More specifically, a water storing tank which is a normal control group, an experimental tank mounted with a pH sensor and a bubble dispersing unit, and another experimental tank mounted with a DO sensor and a bubble dispersing unit are disposed on a water tank table. A running water-type environment is constituted so that a particular quantity of seawater is continuously supplied and discharged through the water storing tank and experimental tanks. CO_2 gas, N_2 gas, or O_2 gas is directly supplied to each of the bubble dispersing units installed in the experimental tanks through a sensor feedback mode using an MFC and a controller. The pH value and dissolve oxygen concentration of the sea water stored in the experimental tanks are maintained at required levels. Accordingly, the impact of marine acidification, which is the pH value of the seawater, on marine organisms and the impact of the dissolve oxygen concentration on marine organisms are simultaneously inspected, so that more particular and systematic environmentally-biological data can be obtained. The running water-type supplying of seawater and the direct feeding technique of gas through experimental tanks are applied, so that a system can be simply formed and more efficient and rational experiment and inspection are possible. The supplying paths of seawater and gas through each of the experimental tanks are constructed through individual single lines, so that confusions caused when the system is operated can be prevented. Also, when the system is broken or defected, the system can be rapidly treated.

Abstract:
A method for diagnosis of maturity by using a polyclonal antibody of rockfish(Sebastes schlegeli) is provided to improve diagnosis accuracy of rockfish maturity by measuring the amount of luteinizing hormone(LH) in rockfish. The method for diagnosis of maturity by using a polyclonal antibody of rockfish(Sebastes schlegeli) comprises the steps of: collecting the pituitary gland of rockfish and purifying it to obtain the rockfish luteinizing hormone; separating rockfish glycoprotein alpha(GPalpha) and rockfish luteinizing hormone beta(LHbeta) from the rockfish luteinizing hormone, and independently obtaining polyclonal antibodies against the rockfish glycoprotein alpha(GPalpha) and rockfish luteinizing hormone beta(LHbeta); and deciding maturity of rockfish through enzyme-linked immunoassay method by using the polyclonal antibody against rockfish luteinizing hormone beta(LHbeta).

CONSTITUTION: The method comprises a first step of naturally drying a sample to be stuffed; a second step of cutting and removing internal organs from the sample; a third step of sewing the cut part after removing the organs; a fourth step of dipping the sewed sample in a specific chemical solution; a fifth step of fixing fins of the sample; a sixth step of artificially and/or naturally drying the sample after introducing specified contents into the sample; a seventh step of detaching and protecting the fins; and an eighth step of completely drying and coloring the sample. The specific chemical solution includes 50cc of formalin, 10g of sodium chloride, 20g of potassium acetate, 10g of potassium nitrate, 50g of boric acid and balance of water to form 1000cc of water solution.
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.
