Samples were collected from three sites: Harer, Salal and Burkah by five types of fishing gears from January 2009 to May 2010. <em>P. abu</em> and <em>C. auratus</em> were the most abundant numerically represented by 14.8% and 13.1% of the total catch, respectively, while <em>T.</em><em> ilisha </em><em>and </em><em>C. luteus</em> comprised 6.1% and 2.2%, respectively. <em>The </em>growth and mortality parameters <em>L<sub>∞</sub></em>, <em>K</em><em>, Z, M</em> and <em>F</em> were 24.6 cm, 0.44, 3.27, 1.03 and 2.24 for <em>P. abu</em>, 42.3 cm, 0.27, 1.87, 1.87 and 1.22 for<em> C. auratus</em>, 57.1 cm, 0.33, 1.55, 0.68 and 0.87 for<em> T. ilisha</em> and 37.9 cm, 0.27, 1.59, 0.67 and 0.92 for<em> C. luteus</em>, respectively. <em> </em>The exploitation rate (<em>E</em>) estimates were 0.68, 0.65, 0.56 and 0.58 for <em>P. abu</em>, <em>C. auratus,</em><em> T. ilisha</em><em> </em>and <em>C. luteus</em>, respectively<em>.</em><em> </em>The results revealed that all species were overexploited. Moreover these values exceeded the maximum allowable limit based on the yield-per-recruit calculation (E<sub>max</sub>) for all species. It is necessary to enforce immediate fishing regulation measures on the fish stock in the investigated location and this can be assessed by activating the national law of fishing, exploiting and protecting aquatic resources.</p> ER -
