Title: Spatio-temporal distribution and secondary production of macrobenthos in intertidal zone of Dongwu of Meizhou Bay,Fujian Province
Abstract: Three sections were set for macrobenthos samplings in intertidal zone of Dongwu in Meizhou Bay,the middle part of Fujian Province,in January and October,2008,following the standards of 'the Specification for Marine Monitoring,part 7:Ecological survey of offshore pollution and biological monitoring'(GB17378.7-2007).As results,a total of 283 species of macrobenthos were identified,including 94 species of Polychaeta,91 species of Mollusca,74 species of Crustacea,9 species of Echinodermata,5 species of fishes and 12 species of other animals.The most abundant species(179) species were in section C.The annual mean biomass and density were 20.07g/m2(wet weight) and 645.9ind/m2,respectively.The most abundant biomass was in section B,the highest density was in section A.The annual mean AFDW(ash-free dry weight) was 3.61g/m2 by Brey's(1990) formula.The mean value of secondary production of macrobenthos was 5.33g(AFDW)/(m2·a),and the annual mean of P/B ratio was 1.93.The species number,biomass and density,secondary production and P/B ratio of macrobenthos in intertidal zone of Dongwu of Meizhou Bay are higher than that in Haitan Strait.
