“…(2015) and Correia et al . (2020), the different length–weight relationships proposed for C. latiscutatus , whether in estuaries or at sea, produced very similar results. Thus, the weight of a 300 mm individual (average fork length in our study) was estimated at 340 g based on the present study, 344 g according to Ecoutin & Albaret, 2003, 338 g according to Ecoutin et al .…”

“…(2015) found a = 0.025 and b = 2.54 ( n = 130, TL range 20–28 cm) and in the PNBA (Mauritania), Correia et al . (2020) estimated a = 0.0026 and b = 3.31 for male and female combined ( n = 346, TL range 24.9–85.5 cm). These results cannot be directly compared with ours as they both concerned total lengths and Ndiaye et al .…”

“…Despite their importance in West African coastal fisheries, there is still little information available on the ecology and biology of these three Ariidae species (Correia et al, 2020). Biometric size-age relationships were proposed for Guinean marine catfish by Conand et al (1995), who highlighted their slow growth and therefore their high vulnerability to exploitation.…”

“…In Mauritania, all three species are fished in the EEZ, most notably C. heudelotii , which over the period 2000–2006 accounted for an average 3378 t/year or 4.1% of the Mauritanian artisanal fisheries catch (Gascuel et al ., 2006). Particularly in the Banc d'Arguin National Park (PNBA), the landings of Ariidae have been increasing from 170 t in 2001 to 450 t in 2007, peaking at 674 t in 2005 (Correia et al ., 2020). In Senegal, Ariidae are one of the main coastal demersal resources, with a high export value, and the industrial Ariidae fishery, which started in 1977 with about 1000 t/year, reached 8892 t/year in 2014 (Diop et al ., 2017).…”

The family Ariidae, sea catfish of the order Siluriformes, is widely distributed throughout the world, particularly in tropical and subtropical areas. The three species of Ariidae found on the coasts and estuaries of West Africa are the smoothmouth catfish Carlarius heudelotii (Valenciennes 1840), the rough-head catfish Carlarius latiscutatus (Günther 1864) and the Guinean sea catfish Carlarius parkii (Günther 1864).They have been increasingly exploited by artisanal and industrial coastal fisheries in recent decades, but there is still little information available on their ecology and biology. The aim of this study was to deepen our knowledge of these three West African Ariidae species based on a dataset collected between 1980 and 2013 during experimental fishing programmes. They were carried out in Mauritania in the Banc d'Arguin National Park, in Senegal in the Sine Saloum estuary including the Bamboung Marine Protected Area (MPA), in The Gambia in the Gambia estuary, in Guinea-Bissau in the Urok Islands MPA in the Bijagos archipelago, in Guinea in the Fatala estuary and Dangara inlet, and in Côte d'Ivoire in the Ebrié Lagoon. C. latiscutatus accounted for 65%, C. parkii for 29% and C. heudelotii for 6% of total number of Ariidae sampled. C. latiscutatus was abundant in the Sine Saloum and Gambia estuaries as well as in Guinea and Guinea-Bissau and was the only species present in the Ebrié Lagoon. C. parkii was in the majority in Mauritania. The three species were recorded in a salinity range of 0 to 50, a temperature range of 19 to 34 C, in areas 1.7 to 15 m depth, and transparency ranging from 0.1 to 4 m (Secchi disk depth). C. heudelotii was present in less saline (25 vs. 32-34), less warm (27 vs. 29 C) and less transparent (0.8 mvs. 1.6 m) waters than the two other species. The maximum sizes (453 mm, 614 mm and 525 mm for, respectively, C. heudelotii, C. latiscutatus and C. parkii) were comparable to those recorded at sea. Length-weight relationships calculated for each species showed b coefficients greater than 3. Sex ratios were always in favour of females. The number of mature individuals and their smallest size at maturity were calculated per species, sex and study area. A size of 27-28 cm at first maturity was estimated for females of C. latiscutatus. A few dozen records made it possible to describe fecundity and cases of oral incubation by females. The diet of the three species was composed of crustaceans, fish and molluscs, confirming their classification as generalist predators. Thanks to their high environmental tolerance, these sea catfish populations are able to occupy both the continental shelf and adjacent estuaries

Along Africa’s western coast, many local communities rely on the ocean for their livelihood. Over the last decades, introductions of new fishing techniques along with globalizing trade have strongly changed local fishing practices. The Parc National du Banc d’Arguin (PNBA) in Mauritania had for centuries been subjected to an artisanal, low‐impact, fishery. This fishing was exclusively oriented towards migratory bony fish species, mullet (Mugil cephalus) and meagre (Argyrosomus regius). Since the 1980s, these species have been replaced by illegal catches of internationally traded elasmobranchs (sharks and rays) and by non‐migratory and relict species (resident) such as tilapias (Sarotherodon melanotheron) and catfishes (Arius sp.). To date, most monitoring and management efforts have been dedicated to evaluating changes in elasmobranch populations and less focus has been on bony fish species. Data from a fishery monitoring programme are used to analyse the trends in effort, catch and catch per unit of effort of bony fish species by fitting non‐parametric generalized additive models to capture changes in the fish community over the last 20 years. Mullet and meagre became overfished early on, and the contribution of resident species (tilapias and catfishes) increased in the catches. Together with a pattern of increased effort on the traditionally targeted species, such a change in the catch could reflect a change in the fish community. These results call for the implementation of sustainable fishing practices within PNBA. We propose the need to implement closures of fisheries during the species’ breeding periods as well as the use of biological reference points such as the size at first capture and maximum sustainable yield targets for resident species.
