Última Self-feeding behaviour and personality traits in tilapia: a comparative study between Oreochromis niloticus and Sarotherodon melanotheron ArchiMer Benhaim, David; Akian, Dieudonne; Ramos, Mathieu; Ferrari, Sebastien; Yao, Kouakou; Begout, Marie-laure. Hybridization aims at combining valuable traits from two species into a single group. Nile tilapia Oreochromis niloticus (NT) and Black-chinned tilapia Sarotherodon melanotheron (BCT) are respectively characterized by fast growth and water salinity tolerance which attract the breeders who could take advantage of both species. The first step is to characterize both species behavior in different contexts. The aim of this study was to compare the self-feeding behaviour between NT and BCT with a design allowing to reveal individual and group feed demand behaviour and then to identify the individual specialization that builds around the device and the food dispenser. The second objective was to estimate the links between the individual specialization and... Tipo: Text Palavras-chave: Boldness; Personality; Self-feeder; Individual specialization; Social structure. Ano: 2017 URL: http://archimer.ifremer.fr/doc/00363/47419/47424.pdf Reproductive behaviour of two tilapia species ( Oreochromis niloticus , Linné, 1758; Sarotherodon melanotheron, Rüppel, 1852) in freshwater intra and interspecific pairing context ArchiMer Akian, Dieudonne; Yao, Kouakou; Clota, Frederic; Lozano, Paul; Baroiller, Jean Francois; Chatain, Beatrice; Begout, Marie-laure. Nile tilapia Oreochromis niloticus (NT) and Black-chinned tilapia Sarotherodon melanotheron (BCT) are respectively characterized by fast growth and water salinity tolerance which attract the farmers who could take advantage of both species characteristics by producing hybrids reared in brackish or marine waters. Little information is however available about social interactions between the two species which are distinct by their mode of parental care (oral incubation). The objective of this study was to determine the behaviour of the two species, NT and BCT placed in freshwater intraspecific and interspecific pairing contexts. Females of both species (n = 20 per species) were first isolated for 90 days in a 60 L aquarium to determine the average duration...
