Title

INVESTIGATION ON SOME OF BIOLOGICAL ASPECTS OF BLACK POMFRET, PARASTROMATEUS NIGER IN OMAN SEA ALONG SISTAN-BALUCHISTAN PROVINCE FOR OPTIMIZING FISHING SEASON

Pages

  57-66

Abstract

 During the years 2003-2004, some biological aspects of black pomfret, PARASTROMATEUS NIGER, have been investigated in the OMAN SEA along SISTAN-BALUCHISTAN Province. Based on the frequency of developed maturity stages (stages IV, V), a prolonged spawning activity with two peaks was designed from March to December; a major one in August and a minor one in March was considered. According to Lm50 percentage (39 cm) and catching fish with 39 cm and above, the stretched optimum mesh size of nets was calculated as 167.7 mm. Based on stomach contents, annelids and shrimp larval showed the highest contribution (29% of the total frequency). POPULATION DYNAMICS parameters were determined through length based modals and the exploitation rate was estimated E=0.54, suggesting a high-level exploitation. The length infinity (L¥), natural mortality (M), fishing mortality (F), total mortality (Z) and growth coefficient per year (K) were 69.1, 0.57, 0.93, 1.5 and 0.26 respectively. also the fish length-weight relationship was determined and parameters a, b and r (correlation coefficient) were obtained as 0.048, 2.8121 and 0.98 respectively.
