“…The preys of C. nigrodigitatus in the Lake Togo-Lagoon of Aného hydrosystem are diverse and includes fish, gastropods, crustaceans, bivalves, plants etc. [24]. However, it is known that the accumulation of trace elements in the tissues of aquatic organisms, such as fish, also depends on their feeding behavior [10] [34] [38].…”

“…Based on the work of Ouro-Sama et al [24], the main species composing the diet of C. nigrodigitatus in the Lake Togo-Lagoon of Aného hydrosystem were collected from two sites during the months of February to July 2017 in collaboration with fishermen from the lagoon complex [25]. The samples were wrapped in batches of species in sterile polyethylene bags and placed in coolers in the presence of a refrigerating equipment and then transported to the laboratory where they were stored at −20˚C [26].…”

The omnivorous fish species, C. nigrodigitatus feeds mainly on benthic organisms and may therefore consume contaminated food throughout its food web. This can lead to the bioaccumulation of contaminants such as trace elements in their tissues. However, fish consumption is a major pathway of human exposure to contaminants which may cause public health problems. The aim of the present study is to assess trace elements contamination in some species from the food web of C. nigrodigitatus. For this, 10 main food items of the silver catfish were collected at two sites from February to July 2017 and analyzed using an Atomic Absorption Spectrometer coupled with a hydride and cold vapour generator. The concentrations of trace elements varied greatly from one species to another and within each species. These values ranged from 0.007 mg/kg for Hg in C hippos to 354.84 mg/kg for Mn in P. fusca. The most contaminated species by trace elements were benthic organisms: M. perna (Cd, Pb, Hg), Pagurus sp. (Cr, Ni, Cu, Zn), G. paradoxa (As) and P. fusca (Mn). The average concentrations of trace elements found in species were, for the most part, above WHO standards except Hg in M. perna and G. paradoxa.The water-based bioconcentration factors (BCFw) reach 92.58 for Cd, 44.

Background and Objective: Knowledge of fish reproduction is crucial to survival and abundance for sustainable use. Thus, a study on the sex ratio, size structure and gonad somatic index (GSI) of Chrysichthys nigrodigitatus in Asejire Reservoir was conducted in Asejire Reservoir, Nigeria to provide information on aspects of reproductive biology for sustainable management. Materials and Methods:The 251 samples of Chrysichthys nigrodigitatus were randomly collected from fishers' catch for seven months covering the wet and dry seasons of 2022 to assess sex ratio, size structure and gonadosomatic indices following standard procedures. Data generated were analysed using descriptive and inferential statistics at α 0.05 . Results: Samples examined had a joint sex ratio of 1:1.5 indicating a more dominant female population across both seasons. The GSI value ranged from 0.53-9.75 (wet) and 0.31-10.69 (dry) while the correlation coefficient between the GSI and body weight was 0.45 (wet) and 0.20 (dry). The result revealed a positive correlation across all relationships except between the GSI and weight in the dry season. Conclusion: The study provides crucial reproductive insights for managing Chrysichthys nigrodigitatus and suggests exploring its aquaculture potential through additional research.
