SOCIAL-CONTROL OF GROWTH IN FISH
(Associação Brasileira de Divulgação Científica (ABRADIC), 1994-04-01)
This review concerns the phenomenon of heterogeneous growth (Het-G) in fish. Het-G is characterized by different growth rates between conspecifics. Although genetic determination on Het-G is recognized, grouping increases ...

Challenges in Assessing Fish Welfare
(Inst Laboratory Animal Research, Natl Res Council, 2009-01-01)
Descriptions of feeling states in nonhuman animals have relied on indirect evidence from empirical data. Assumptions that fish do not experience suffering lack evidence and in fact contradict a large body of indirect ...
Insights into the concept of fish welfare
(Inter-research, 2007-05-04)
Fish welfare issues are predicated on understanding whether fish are sentient beings. Therefore, we analyzed the logic of the methodologies used for studying this attribute. We conclude that empirical science is unable to ...
