Abstract:
PURPOSE: A method for measuring breeding amount of Laternula elliptica using an immunological technique is provided to accurately calculate recruitment and to determined optimal environment capacity. CONSTITUTION: A method for measuring breeding amount of Laternula elliptica comprises: a step of purely isolating eggs from Laternula elliptica and isolating p154; and a step of applying the antibody on ELISA and selectively detecting only eggs from Laternula elliptica. The egg protein of a Laternula elliptica extract is quantitatively measured.
Abstract:
PURPOSE: A hanging bivalves raising device is provided to decrease a mortality rate while promoting the growth of benthic bivalves. CONSTITUTION: A hanging bivalves raising device includes a cage(10) and fiber yarn. A plurality of through holes are formed on a surface of the cage. The cage is charged with the fiber yarn. The charging density of the fiber yarn is 0.2 to 20kg/m3.
