Dynamique De La Population De La Crevette D’eau Douce Atya Scabra (Leach, 1815) (Decapoda: Atyidae) Dans La Rivière Bia, Région Du Sud-Comoé (Côte d’Ivoire)
Abstract:The parameters of growth, mortality, the exploitation and the recruitment of Atya scabra (Leach, 1815) as traditionally fished in the Bia river, were studied. These parameters were determined from the size frequencies by the FiSAT II software. The results obtained at the specimens of Aboisso were:= 156,45 mm, K = 1,50 year -1 , Φ' = 4,56, Z = 5,72 year -1 , M = 1,48 year -1 , F = 4,24 year -1 and E = 0,74 year -1 . In Biaka, the estimated values were: L = 140,7 mm, K = 0,68 year -1 , Φ' = 4,13, Z = 1,52 year … Show more
