METHOD FOR ARTIFICIALLY FILLING UP SEA URCHIN GONAD

摘要

PURPOSE: To artificially and efficiently fill up a gonad of a sea urchin to a commercially utilizable extent regardless of seasons by housing the sea urchin having an unfilled gonad in a water tank, regulating the water temperature to a specific temperature and rearing the sea urchin for a prescribed period. ;CONSTITUTION: A sea urchin having an unfilled gonad such as preferably red sea urchin, purple sea urchin or Strongylocentrotus nudus is housed in a water tank and the water temperature in the water tank is regulated to a temperature below the maturing temperature of the sea urchin or exceeding the temperature to rear the sea urchin for a prescribed period. Thereby, the gonad of the sea urchin can artificially be grown extremely large in a short period.;COPYRIGHT: (C)1993,JPO&Japio
