Dominance and growth ofDiplodus sargus(Pisces: Sparidae) in small captive groups

Publication year: 2012 Source: Applied Animal Behaviour Science, Available online 8 February 2012 Ana Ribeiro Gonçalves, Liliana Carvalho de Sousa, Vitor Carvalho Almada The dominance hierarchies and the growth rate of the commercially important fishDiplodus sarguswere assessed in this study. Specifically, we tested the hypothesis that, if stable dominance orders were established, dominant fish would grow faster and show better condition factors than losers at the end of the experiment. Eight groups of six individuals were followed for 6 weeks and, for each group, we measured the linearity of the hierarchies on a weekly basis, and the week to week stability of the hierarchical structures
