This study on Eucinostomus melanopterus was conducted from September 2014 to June 2016 in the Saloum estuary. Samples were collected using gillnets (monofilament polyamide) with 28; 30; 32; 36 and 40 mm of mesh size (Knot to knot). The aim of this study was to provide information on length frequency distribution, length-weight relationship and condition factor for E. melanopterus in the Saloum estuary. Analysis of the size frequency distribution was bimodal with modes equal to 13 and 18 cm, respectively. The length-weight relationship showed positive allometric growth with b = 2.966. Values of condition the factor were greater than 1, indicating that individuals of E. melanopterus were in good physiological condition. The highest K value is obtained in the transition period between the hot and cold season (K = 1.327±0.059) and the lowest value in the transition period between the cold and hot season (k = 1.21±0.083).
Author Keywords: Saloum estuary, condition factor, Fishery, Gerreidae.

Abstract
This study on Eucinostomus melanopterus was conducted from September 2014 to June 2016 in the Saloum estuary.

The aim of this study was to provide information on length frequency distribution, length-weight relationship and condition factor for E. melanopterus in the Saloum estuary. Analysis of the size frequency distribution was bimodal with modes equal to 13 and 18 cm, respectively. The length-weight relationship showed positive allometric growth with b = 2.966. Values of condition the factor were greater than 1, indicating that individuals of E. melanopterus were in good physiological condition. The highest K value is obtained in the transition period between the hot and cold season (K = 1.327±0.059) and the lowest value in the transition period between the cold and hot season (k = 1.21±0.083).
