Abstract
Concentrations of selected metals (Cd, Co, Cr, Fe, Mn and Pb), oxidizable organic carbons, sediment acid potentials, dissolved oxygen (DO), dissolved solids, suspended solids, pH, conductivity, salinity and temperature in the Inanam River Estuary and the KO-Nelayan tiger prawn aquaculture ponds were monitored during the period March to August 1989. Dissolved Co and Pb were found to be higher than the recommended values of 0.05 mgl−1 (Krenkel & Novotny, 1980; Nemerow, 1985), whereas the other metals were comparable to the recommended safe levels. DO concentrations of the river and pond water were in the range 2.6–4.7 mgl−1 and 3.0–5.3 mgl−1 respectively, both with an average which was lower than the optimum value for the growth of prawns which is 5 mgl −1. Ferrous sulfide concentrations were in the range 0.14–1.20%. Suspended solids were higher than the maximum (40 mgl −1) recommended value by WHO (1978). Other physical parameters were within the recommended range for optimal growth of tiger prawns.
