“…The "k" value obtained in this study shows no significant difference (P < 0.05) but greater than 1. The "k" value recorded in this study varied slightly from the result of Mohammed (2010), Abdul et al (2016), Famoofo and Abdul (2020).…”

“…The Length-weight relationship is an important data when estimating fish biomass and has been accepted internationally as a vital tool in fish biology, physiology, ecology, population dynamics and stock assessment (Abdoli et al, 2008;Ferreira et al, 2008;Epler et al, 2009;Nowak et al, 2009;Abdul et al, 2016). Eyo and Awom (2016) stated that in evaluating fish well-being and growth patterns, LWR data is reliable but is seriously affected by many factors such as pollution, population variability, sampling season, estimation methods, food availability, feeding intensity, size of fish, age of fish, sex, maturity stage, muscular development and quantity of reserved (Gayando and Pauly, 1997;Kimmerer et al, 2005;Masoud et al, 2006;Olim and Borges, 2006;Ujjania et al, 2012;Abdullahiand Ahmad, 2013;Miller et al, 2015;Gupta and Banerjee, 2015;Al Nahdi et al, 2016;Famoofo and Abdul, 2020).…”

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

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.

“…Ayoade and Onibonoje (2013) reported positive allometric growth for male S. galilaeus and negative allometric growth for female fish in Eleyele Lake, Nigeria. Difference in the growth pattern can be due to difference in sex, maturity stages, seasonality; time of day, food eaten or available to the fish, changes in the specific gravity and shape of the body contour (Prasad and Anvar 2007;Abdul et al 2016).…”

Oyan Lake is one of the major sources of fish protein supply to many parts of Southwestern Nigeria. Investigation was conducted on the biometrics, length-weight relationship and condition factor of Sarotherodon galilaeus in Oyan Lake. Fish samples were obtained from fishermen using gillnets, hook and line, cast nets and traps. One hundred and thirty samples of S. galilaeus were collected for the study, comprising eighty-three (83) males and forty-seven (47) females with sex ratio of 1:0.57 (male:female). The mean total lengths for combined sexes, males and females were 15.5±0.15, 15.7±0.19 and 15.3±0.26cm while the mean total weights were 81.0±2.78, 83.8±0.56 and 75.9±4.70g, respectively. No significant difference (p>0.05) was observed between mean total lengths of males and females. However, mean weight of males was significantly higher (p<0.05) than females. Mean eye diameter (EYD) and length of caudal peduncle (LCP) were significantly higher (p<0.05) in females. The range of number of pectoral rays (PRA) (12-14), number of pelvic rays (PVR) (4-5), number of anal spines (ANS) (2-3) and number of pelvic spines (PEVS) (1, no range) were the same in both sexes. There was strong correlation between weight/total length (r=0.93) and total length/length of dorsal fin base (r=0.72), while there was no correlation between body depth/head length. The mean condition factor (k) were 2.07±0.02 (combined sexes), 2.08±0.03 (males) and 2.03±0.03 (females). Growth was isometric for both sexes: males, 3.24 and females, 3.06. The results suggested that Oyan Lake is suitable for S. galilaeus.

This study examined the length-weight relationship and condition factor of Hydrocynus forskahlii (Cuvier, 1819) in River Yobe, Northeast, Nigeria. A total of 350 fish species were collected from commercial fishermen at four landing sites (Gogaram, Dogona, Bize, Azbak) within the study area between June to November 2020. The morphometric and meristic characteristics examined could be attributed to environmental variations (water temperature, stress, food availability, spawning ground, fishing intensity and sex). Monthly mean condition factor (1.19 ± 1.03) shows significant difference (P 0.05) during the sampling duration while highest mean condition factor was recorded in October (1.38 ± 1.15). Also change in weight of the sampled fish was caused by 77.4% change in length. A linear relationship was established with b value (1.2656) indicating a negative allometric growth pattern while correlation coefficient (r2 = 0.7775) indicated that LWR model is reliable. This study bridged literature gap on LWR and condition factor of Hydrocynus forskahlii in River Yobe, hence further research should be encouraged on the water body for sustainable utilization, decision making and policy formulation.
