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:
An abalone is a type of mollusk included in archaeogastropoda haliotidae. Abalones inhabit low-water level areas of oceanic islands or rocks having a depth of 5-50 m under the sea. An oceanic place where the water is clean and plenty of seaweeds are propagated is good for abalones to live. However, abalone harvests are currently decreasing due to a lack of adhesive diatoms which are used as an initial food for abalones. The cultivation of adhesive diatoms in oceanic farms in Jeju and the Korean East Coast is more difficult than in back bays because they contain less nutrient salts than the back bays. Accordingly, the present invention exhibits a practical culture medium for culturing adhesive diatoms used as a food for abalones. In the cultivation for adhesive diatoms used as a food for abalones, composite fertilizers and urea fertilizers are used as main materials so that the unit cost of the culture medium is reduced. Culture mediums having a particular concentration are continuously supplied so that the propagation of the adhesive diatoms is activated to increase productivity. A culture medium of the present invention is managed continuously until all procedures for producing abalones products are finished, so that the mass mortality of early young shells is reduced and a large amount of healthy abalone shells can be produced.

Abstract:
PURPOSE: A partitioned water tub capable of rotating, attaching and detaching is provided to prevent stress caused by accommodating different kinds of fishes, to extend the life time of fishes, to improve space use of the tub, and to secure convenience for managing fishes according to their sizes. CONSTITUTION: An outer pipe(40) is also formed inside the tub with a drain hole, and an inner pipe(60) connected to the outside of the main body is formed inside the outer pipe. The partition of the tub has a form selected from one between: partitioning the inside by contacting the partition frame and the partition fence in a straight line, and partitioning the inside by contacting the partition wall and the partition frame in the state that their sides are partially out of joint.
