Assessment of length-weight relationship and condition factor of Synodontics omias (Cuvier, 1816) in River Komadougou, Northeast, Nigeria

Abstract

Length-weight relationship and condition factor of Synodontics omias (Cuvier, 1816) was studied between June to November 2020 in River Komadougou, Northeast, Nigeria. A total of 350 fish species were collected from artisanal fishermen at selected landing sites within the study area. The morphometric and meristic characteristics examined varies whereas some meristic features such as pelvic and dorsal fin spine had a constant value of 1 each. The mean condition factor shows no significant difference (P 0.05) throughout the sampling period. A linear relationship was established W = -0.82L1.91 and significant at P 0.01 with b value indicating a negative allometric growth pattern. The correlation coefficient (r2 = 0.7904) indicated that LWR model is reliable. This study provides baselines on length-weight relationship and condition factor of Synodontics omias in River Komadougou, thus further research should be encouraged on the water body for sustainable utilization, decision making and policy formulation.
