Morphometric Measurements Relationships of Synodontis batensoda (Rueppell 1832) from Forcados River, Toru-Orua, Bayelsa State, Nigeria
Abstract
The Length Weight Relationship (LWR) and Condition Factor (K) of an IUCN red listed but LC categorized species, Synodontis batensoda, from River Forcados, Sagbama, Bayelsa State was investigated. A total of 50 specimens from two fishing communities using gillnet along the River Forcados, comprising of 20 females and 30 males were sampled and studied between June and July, 2023. Results from combined communities showed Weight (W) for the female fishes ranged from 10.0 g - 46.0 g with mean 26.650 g, while that of the males ranged from 16.0 g - 65.0 g with mean 36.533 g. The Total Length (TL) for female fishes ranged from 10.4cm-16.3cm with mean 13.590cm, while males ranged from 12.4 cm - 18.5 cm with 15.210 cm. The LWR was calculated using the equation W=aL^b and K=100(W/L^3). The LWR obtained were the combined communities, Ebedebiri and Angalabiri separately were W=0.0067L^(3.1565), W=0.0071L^(3.1357), and W=0.0067L^(3.1515), with Correlation Coefficient (r) values highly significant at 0.971, 0.968, and 0.979. The K values are, 1.0179, 1.0266, and 1.0073, respectively. Statistically, means of TL, W, and K from both communities were not significantly different (P > 0.05) with P values of 0.195, 0.189, and 0.462. Sampled sexes from Ebedebiri community were significance different (P < 0.005) in TL and W, P = 0.005 and 0.02 respectively, but K value for the sexes were not significantly different (P > 0.05) at P = 0.618. Angalabiri showed similar results to Ebedebiri for both TL and W (P < 0.05), P = 0.00015 and 0.001. Also similar was the K value at P > 0.05 (P = 0.382). Both communities showed a positive allometric growth (b = 3.1565) indicating that Forcados River environmental factors favour the growth of S. batensoda in the study communities during the period of its availability.
