广东省的紫菜人工采苗养殖事业起始于1966年9月,当时从福建运回坛紫菜(Por-phyra haitanensis T.J.Chang et B.F.Zheng)的丝状体采苗养殖,并取得了一定的效果。为广东省开展紫菜人工养殖创造了条件。广东地处热带、亚热带地区,水温较高,坛紫菜在汕头地区的收获时间只有2个月左右,生长期短,再加上养殖技术问题尚未很好地解决,产量一直不高,远远不如福建、浙江。据汕头地区水产局的统计,全区平均产量最高亩产仅81公斤,最低只有13.5公斤(干品,下同)。这对广东沿海大力开展群众性的紫菜养殖带来很大的困难。
Guangdong laver artificial seedling breeding business began in September 1966, at that time from Fujian shipped back altar seaweed (Por-phyra haitanensis T.J.Chang et B.F.Zheng) filamentous seedling culture, and achieved some results. Guangdong Province to carry out artificial breeding of seaweed to create the conditions. Guangdong is located in the tropical and subtropical regions, the water temperature is high, algae seaweed in Shantou area harvest time is only about 2 months, short growth period, coupled with farming technology has not been properly resolved, the yield has been low, far less Fujian, Zhejiang. According to statistics from the Bureau of Fisheries in Shantou, the average yield per mu in the entire district is only 81 kg and the lowest is only 13.5 kg (dry goods, the same below). This will bring great difficulties to carry out masses of seaweed farming along the coast of Guangdong Province.
