FUNDAMENTAL OBSERVATIONS ON GRACILARIA CULTURE
꼬시래기 양식에 관한 기초적 조사
Abstract
Experiments were carried out to asses the impotance of environmental conditions upon the growth rate, length compositions seedling and spore liberation of a red alga Glacilaric verrucosa. The alga grown in water of low salinity mixed with fresh water shows better growth rate, lager length composition and excellent seedling, whereas the one vegetated in an area of tidal exposure shows a somewhat retarded growth rate and poor seedlings. The rate of growth Increases from August to October and begins to diminish from December continuing to diminish through February. Therefore the spore settling time extends from May to lune. Although the sun-drying method is the most eacient way of inducing spore liberation, further investigations are necessary in oiler to use this method for the application to artificial spore settling.
