Abstract

Annual variation of primary production and chlorophyll-a of the inshore area ofTuticorin indicated three peak periods. during March-April. June-July and September-October. The multipfe regression analysis indicated significant levels of co-relation by chlorophyll-a and nitrates with primary production. Among nutrients only nitrate and phosphate have influence on primary production while nitrite and silicate have insignificant role. The usefulness of chlorophyll-a in relation to the primary production rates as a measure of.the standing crop of phytoplankton and the role of nutrients in the organic production of the inshore area of Tuticorin are also briefly discussed
