Abstract:
A mixing apparatus for automatically adjusting salinity comprises a first pipe for collecting seawater from the sea and supplying the collected seawater, a first flow control valve and a first salinity sensor which are formed on one side of the first pipe, a central processing unit (CPU) for receiving a value measured by the first salinity sensor and controlling the opening and shutting of the first flow control valve, a second pipe for supplying fresh water, a second flow control valve formed on one side of the second pipe, and a supply pipe for connecting to the first flow control valve with the second flow control valve, in order to use, as breeding water of a farming water tank, seawater which changes depending on seasonal precipitation and coastal water that flows from land. The mixing apparatus measures the salinity of seawater that flows into the farming water tank, and drives the seawater and fresh water pipes and the first and second flow control valves, based on the measured salinity of seawater, to mix fresh water with breeding water with an amount of sodium chloride of constant concentration, even when the salinity of seawater changes depending on the time and season of the year, thereby easily adjusting the salinity of the breeding water. As a result, the mixing apparatus can reduce human resources and costs required to supply the breeding water, and enables intensive high-density farming by stably supplying seawater of constant concentration.

Abstract:
The present invention provides a test method for quickly identifying infection by a small amount of Azumiobodo hoyamushi using loop-mediated isothermal gene amplification (LAMP). In order to develop a high sensitive test method using an LAMP reaction, the sensitivity and the specificity in Azumiobodo hoyamushi and Halocynthia roretzi with soft tunic syndrome are analyzed by preparing a primer set for LAMP containing six primers to target kinetoplast 18S ribosome genes of Azumiobodo hoyamushi and amplify a reactant with a specific loop type; and establishing an optimal reaction condition. Thus, Azumiobodo hoyamushi which is known for causing soft tunic syndrome is quickly detected from sea water or Halocynthia roretzi with the initial stage soft tunic syndrome using the LAMP reaction and damage spread is early detected by applying the method to a system for predicting soft tunic syndrome in farmed Halocynthia roretzi.

PURPOSE: A method for breeding Paralichthys olivaceus is provided to improve growth and body shape of the Paralichthys olivaceus. CONSTITUTION: A breeding method for enhancing growth efficiency of Paralichthys olivaceus comprises: a step of analyzing genotype of male and female group of Paralichthys olivaceus; a step of calculating genetic relation between each individual of female group and male group according to the equation 1; a step of selecting male individual of which relation value with a female individual is less than 0.2; a step of selecting 3 individuals male individual; a step of performing artificial fertilization; and a step of growing F1 generation prepared by hydridization.
Abstract:
PURPOSE: A system and a method for automatically measuring the trait of fishes are provided to increase the accuracy of data by forming database based on the obtained image information and measured data related to the fishes. CONSTITUTION: A conveyor image taking part(100) takes images with respect to the front side and the lateral side of fishes on a conveyor and transfers the images. A conveyor weighing part(200) weights the fishes on the conveyor and transfers the weights of the fishes. A trait measuring part(300) measures the trait of the fishes based on the front and the lateral images of the fishes and measures the fatness of the fishes based on the weights of the fishes. The information related to the image, the trait, the weight, and the fatness of the fishes are stored and managed.
