    Benthic Nacrofaunal Productivity and Diversity of the Red Sea Coast Around Tewalit (Massawa
    (Addis Ababa University, 1987-06) Melake, Kiflemarian; C. Davis, Charles (Professor)
    The Di versi ty and Productivity of benthic macl'ofauna around the shallow waters of Tewalit (Massawa) were investigated at three stations from October 28,1986 to April 14,1987. Eight major groups and 50 taxa were encountered. Polychaetes with 23 taxa were the most diverse group followed by gastropods with 8 taxa, and crustaceans Hith 6 taxa. Physical and chemical parameters show no significant variation and regulatory effec-t over the distribution and abundance of the taxa. The taxa indicate a high species diversity, biomass diversity and equitability. There is significant variation in similarity indices, but no variation in species composition among the stations. Productivity is estimated to be lO.16g/m2. This with mean biomass 6.9g1 m2 resulted in a turnover rate (P:B ratio) of 1.5.
