The article aims to highlight body development through weight monitoring and other morphometric parameters of Clarias gariepinus reared in concrete tanks and floating cages for 150 days. Then, 6400 individuals with average body weight (103.91 ± 32.74 g) and initial total length (24.08 ± 2.31 cm) were distributed in two floating cages (5 x 5 x 2.5 m3) on Lake Toho in Benin and two concrete tanks (3.8 x 3.8 x 1.5 m3) at densities of 2000 individuals / cage and 1200 individuals / tank respectively. The fish were hand-fed three times a day until apparent satiety with a pelleted commercial feed containing 45% crude protein. The results obtained showed better performance in floating cages than in tanks and were respectively as follows: total length (53.37 ± 6.31 vs 43.47 ± 4.56 cm), standard length (48.10 ± 5.58 vs 38.86 ± 4.32 cm), pre-dorsal length (15.20 ± 2.16 vs 12.46 ± 1.62 cm), length of the head (9.74 ± 1.92 vs 7.48 ± 1.13 cm), dorsal fin base length (30.19 ± 4.46 vs 24.46 ± 2.97 cm), interorbital width (5.78 ± 1.89 vs 4.50 ± 0.61 cm), body height (6.45 ± 1.14 vs 5.20 ± 0.80 cm), height of the caudal peduncle (4.12 ± 0.66 vs 3.32 ± 0, 49 cm), body weight (1245.43 ± 479.33 vs 661.91 ± 230.51 g). This confirms that when conditions permit, the use of floating cages is to be promoted.

Abstract
The article aims to highlight body development through weight monitoring and other morphometric parameters of Clarias gariepinus reared in concrete tanks and floating cages for 150 days. Then, 6400 individuals with average body weight (103.91 ± 32.74 g) and initial total length (24.08 ± 2.31 cm) were distributed in two floating cages (5 x 5 x 2.5 m3) on Lake Toho in Benin and two concrete tanks (3.8 x 3.8 x 1.5 m3) at densities of 2000 individuals / cage and 1200 individuals / tank respectively. The fish were hand-fed three times a day until apparent satiety with a pelleted commercial feed containing 45% crude protein. The results obtained showed better performance in floating cages than in tanks and were respectively as follows: total length (53.37 ± 6.31 vs 43.47 ± 4.56 cm), standard length (48.10 ± 5.58 vs 38.86 ± 4.32 cm), pre-dorsal length (15.20 ± 2.16 vs 12.46 ± 1.62 cm), length of the head (9.74 ± 1.92 vs 7.48 ± 1.13 cm), dorsal fin base length (30.19 ± 4.46 vs 24.46 ± 2.97 cm), interorbital width (5.78 ± 1.89 vs 4.50 ± 0.61 cm), body height (6.45 ± 1.14 vs 5.20 ± 0.80 cm), height of the caudal peduncle (4.12 ± 0.66 vs 3.32 ± 0, 49 cm), body weight (1245.43 ± 479.33 vs 661.91 ± 230.51 g).

Abstract: (french)
L’article a pour but de mettre en exergue, le développement corporel à travers le suivi du poids et autres paramètres morpho métriques de Clarias gariepinus élevés en bassins bétonnés et cages flottantes pendant 150 jours. Pour ce faire, 6400 individus de poids corporel moyen (103,91±32,74 g) et de longueur totale (24,08±2,31cm) initiaux ont été répartis dans deux cages flottantes (5 x 5 x 2,5 m3) sur le lac Toho au Bénin et deux bassins en béton (3,8 x 3,8 x 1,5 m3) aux densités respectives de 2000 individus/cage et 1200 individus/bassin. Les poissons ont été manuellement nourris trois fois par jour jusqu’à satiété apparente avec un aliment commercial granulé contenant 45% de protéines brutes. Les résultats obtenus, ont montré de meilleures performances en cages flottantes qu’en bassins et se présentent respectivement comme il suit: longueur totale (53,37±6,31 vs 43,47±4,56 cm), longueur standard (48,10±5,58 vs 38,86±4,32 cm), longueur pré dorsale (15,20±2,16 vs 12,46±1,62 cm), longueur de la tête (9,74±1,92 vs 7,48±1,13 cm), longueur de la base de la nageoire dorsale (30,19±4,46 vs 24,46±2,97 cm), largeur inter orbitaire (5,78±1,89 vs 4,50±0,61 cm), hauteur du corps (6,45±1,14 vs 5,20±0,80 cm), hauteur du pédoncule caudal (4,12±0,66 vs 3,32±0,49 cm), poids vif corporel (1245,43±479,33 vs 661,91±230,51 g). Ceci confirme que lorsque les conditions le permettent, l’utilisation des cages flottantes est à promouvoir.
