Description:
Seaweeds culture project emphasizing on Gracilaria was carried out from 1378 to 1380. In this research five spices of seaweeds were selected and cultured in various seasons. (Gracilaria corticata, Ulva fasiata , Sargassutn ilisifolium , Cystosira indica , Nizimuddinia zanardinii ) Gracilaria reached to maximum growth in about 35 days, And biomass were 2.5 to 3 times. One way anova in sea culture showed that average weight were similar in various seasons. ln ponds culture were not similar in various seasons and there showed significant difference. Maximum growth of Ulva was in spring and summer, and biomass were 5 times in about to 28 days. That showed average weight and growth of this species was not similar and showed significant difference. Cystoseira reached 5 to 7 times about 45 days, and it,s high growth was in autumn and winter. Result of one way anova showed significant in average weight. Sargassum reached 3 to 5 times about 45 days, and had high growth in autumn and winter. Average weight was similar in the open sea,s but that showed significant difference in ponds. Nizimuddinia hadn’t adequate growth in ponds, but that reached 3 to 5 times in sea. Average weight showed significant difference in various seasons. According to results, growth of gracilaria was similar in the various seasons, and brown algae had better growth in autumn and winter. Greenalgea in spring and summer.
