Fishes were collected during several scientific fishing surveys using purse seine (length 250 m, height 20 m, 14 mm mesh size) and beach seine (180 m length, 9 m height and 25 mm mesh net) conducted from April 1990 to October 2012 in the Sine Saloum estuary, Senegal. They were weighed to the nearest g and measured to the nearest mm (disc width for Fontitrygon margaritella and total length for the 4 other species). The values of parameter b in the LWR equations varied from 3.048 (Chaetodipterus lippei) to 3.274 (Dagetichthys cadenati) and the coefficient of determination (r(2)) varied between 0.969 (Fontitrygon margaritella) and 0.998 (Chaetodipterus lippei). In addition, new maximum lengths are proposed for Fontitrygon margaritella, Chaetodipterus lippei and Dagetichthys cadenati. specialized estuary fish species length-weight relationships Senegal sine saloum SENEGAL 034 [Early access] [3 p.] 2021 0175-8659 https://www.documentation.ird.fr/hor/fdi:010082119 10.1111/jai.14230 0175-8659 [F B010082119] https://www.documentation.ird.fr/hor/fdi:010082119 https://www.documentation.ird.fr/intranet/publi/2021-07/010082119.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2021-07-02 2025-02-24 fdi:010082119 fre
