Preliminary Study on the Soft Raft Cultivation Techinque of Sargassum fusiforme in Shallow Water Area at Dachen

The soft rafts was used to cultivate Sargassum fusiforme which was chosen from the native natural seawater,the results were as follows: Sargassum fusiforme grew rapidly in the earlier stage and slowly in the later stage that had great relation to the water temperature,thereinto slowest in December,most rapid in May and April took the second place,from September 28th in 2005,it took a period of 7 months cultivation until May in 2006 when the Sargassum fusiforme came into the market.Until the end of June,all production were reaped and weighted 13 660 kilogram totally from the cultivated area of 2 000 square metre,the production value is 207 632 yuan in which the net income is 96 632 yuan.Benefit gained is 3 221.06 yuan per 667 square metre.
