  1. IS WHERE YOU LIVE...WHO YOU ARE??? Influence of rearing environment on behaviour and growth of sole (Soleasolea) Julia Mas-Muñoz1,2,3, Hans Komen2, Oliver Schneider3, Johan Verreth1and Johan W. Schrama1 Objective Conclusions Explorative behaviour of sole in a novel environment is context dependant Rearing environment influences the relation between individual behaviour and growth of sole Experimental design Results 6 treatments: 1. Explorative behaviour of fish in a Novel Environment • Rearing Environments: SR, SP, BP • What? • Substrate: Sand (S) vs. Barren (B) • Feed : Ragworms (R) vs. Dry feed (P) • Where? • Environment: Outdoor vs. Indoor • Indoor: Controlled light and Temp • Outdoor: Variable light and Temp • How? • 20 fish/tank • 4 replicates • Duration? • Growth period of 40 days N.S. SR SP BP 2. Relationship between individual behaviour and growth • Novel environment Test • When? • BEFORE and AFTER reared in environment • Where? • Circular barren bottom tanks • What? • Swimming activity (sec) per fish during 10 min observation Spearman correlations between swimming activity of fish in a novel environment and growth (g/kg0.8/d) *p<0.05, **p<0.01, ***p<0.001, # p<0.1, N.S not significant 1Aquaculture and Fisheries Group, Wageningen University, The Netherlands 2Animal Breeding and Genetics Group, Wageningen University, The Netherlands 3Wageningen IMARES, Yerseke, The Netherlands Address: De Elst 1, P.O. 338 6700AH Wageningen, The Netherlands Tel: (+31) 0317-483307 Fax: (+31) 0317-483937 Email: Julia.mas@wur.nl
