漳江口红树林国家级自然保护区海产品产量产值研究

Yield and Value of Fishery Products of Zhangjiangkou Mangrove Forestry National Nature Reserve

2006年全年对福建漳江口红树林国家级自然保护区红树林主要分布地竹塔村辖区内的海产品类型、产量和价格进行了逐日统计。结果表明:2006年竹塔村滩涂海产品总产量为529956kg(1589.9kg/hm2),远高于一般的红树林。其中缢蛏苗和缢蛏成品的产量最高,分别为312468kg(937.4kg/hm2)和123376kg(370.1kg/hm2),占总产量的59.0%和23.3%。泥蚶、锯缘青蟹成品和泥螺分别占总产量的12.2%、2.3%和2.0%。缢蛏苗以冬季(1月和12月)的产量最高;锯缘青蟹苗年产量为2.59尾/m2,高峰期出现在6月至11月。2006年竹塔村红树林滩涂海产品总产值为1388.0万元(4.17万元/hm2)。研究结果可为红树林生态系统服务功能的评价和红树林的科学管理提供基础数据。

Daily investigation of the yield and value of the main fishery products within a mangrove area of Zhuta village in Zhangjiangkou Mangrove National Nature Reserve were surveyed throughout the yearof 2006. Results showed that the total yield of fishery products in this area was 529 956 Kg （1589.9kg/hm^2） in 2006, much higher than that of the normal mangrove areas. The yields of young and adult Sinonovacula constricta were the highest among the fishery products, respectively 312 468 kg （937.4kg/hm^2） and 123 376 kg （370.1kg/hm2）, accounting for 59.0% and 23.3% respectively of the total fishery yields. Tegillarca granosa, adult Scylla serrata and Bullacta exarata were the secondimportant fishery products, accounting for 12.2%, 2.3% and 2.0% of the total fishery products respectively. The yield of young S：honovacu/,7 constr/cm peaked in winter （January and December） and the peak season of young Scylla serrata appeared between June and November. The annual fishery products value was 13.88 million Yuan （41 700 Yuan per hm^2）. The results provide a basis for the evaluation of ecological services of mangroves and for its sound management.
