| Resumo: |
Investigating the biological mechanisms linking environmental variability to fish production systems requires the disentangling of the interactions between habitat, environmental adaptation and fitness. Since the number of environmental variables and regulatory processes is large, straightening out the environmental influences on fish performance is intractable unless the mechanistic analysis of the 'fish-milieu' system is preceded by an understanding of the properties of that system. While revisiting the key points in our currently poorly integrated understanding of fish ecophysiology, we have highlighted the explanatory potential contained within Fry's ( Fry 1947 Univ. Toronto Stud. Biol. Ser. 55, 1 - 62) concept of metabolic scope and categorization of environmental factors. These two notions constitute a pair of powerful tools for conducting an external ( at the emerging property level) analysis of the environmental influences on fish, as well as an internal ( mechanistic) examination of the behavioural, morphological and physiological processes involved. Using examples from our own and others work, we have tried to demonstrate that Fry's framework represents a valuable conceptual basis leading to a broad range of testable ecophysiological hypotheses.
