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 genetic method for distinguishing colour variant in Stichopus japonicus Selenka and to improve accuracy of distinguishing. CONSTITUTION: A genetic method for distinguishing colour variant Stichopus japonicus Selenka using allele-specific PCR comprises: a step of isolating genome DNA of HSP70 from variants in Stichopus japonicus Selenka; a step of adding a primer set of sequence numbers 2 and 3 and an allele-specific primer of sequence number 4 to the isolated DNA for performing PCR; and a step of determining the species. The primer of sequence number 4 is used for allele-specific PCR amplification to distinguish the color of Stichopus japonicus Selenka.
