The Condition Factor, Length-Weight Relationship and Abundance of Elops seneganensis (Regan, 1909) from Nkoro River, Niger Delta, Nigeria
並列摘要
The condition factor, length-weight relationship and abundance of Elops senegalensis from Nkoro River in the Niger Delta area of Nigeria was studied for aperiod of one year (January-December 2008). From a sample size of 1325 specimens, K value was 0.941 and the exponential equation was Wt=0.0153 (TL)^3.066, indicating an isometric growth pattern. The highest catch was recorded in December (1.62), followed by August (1.41), July (1.28), January (1.12), February (1.01) and March (0.64), November (0.60), September (0.59), October (0.14), April (0.12) and May (0.11). E. Senegalensis occurred all year round during the study. The highest condition factor value (1.00) was recorded in January and the lowest (0.40) in October. The highest catch per unit effort (3.42) was recorded in stations 1, followed by station 2 (3.11), station 4 (2.11) and station 3 (0.12). Although E. Senegalensis from Nkoro River occurred all year round, the specie was more abundant in the dry season months of December and January; and also in the heavy rains months of July and August.
