Title

ESTIMATION OF POTENTIAL YIELD ON DEMERSAL FISHERY RESOURCES BASED ON THE PRODUCTION OF MACROBENTHIC FAUNA IN THE CHABAHAR BAY

Pages

  77-102

Abstract

 Population density, distribution and biomass of MACROBENTHIC fauna in CHABAHAR BAY were investigated from May 1995 to March 1996 on a bimonthly basis. The most abundant groups were Amphipods (21.0%), Polychaetes (19.0%), Gastropods (15.7%) and Bivalves (10.6%). Maximum (13000 individuals/m2) and minimum (4600 individuals/m2) were observed in May and July, respectively.The changes in density were influenced by monsoon season of the Indian Ocean. Spatial and temporal variation in biomass were recorded for all groups seperately. The lowest biomass was observed during monsoon period (July-September) with a mean of 51.5 g dry wt/m2 and the highest in premonsoon period (March-May) with an average 164.8g dry wt/m2. Furthermore, the average biomass of total macrofauna III the survey area estimated as 109.3 (±49.6)g dry wt/m2 (corresponding to 481.0g wet wt/m2). Having these figures, the annual production of MACROBENTHIC fauna was decreasing trend.In a conclusion, the concentration of dissolved sillicon and biomass of diatoms ould be affected by different physical parameters such as: water circulation, river currents, exchange of biogenic sediments in photic and aphotic zones. Also, there was a significant relationship between the biomass of diatoms and silicon concentration.
