Adaptive trade-offs define the trait combinations that differentiate taxa and allow coexistence
along environmental gradients. To understand the physiological trade-offs associated with …

Juveniles of different salmonid species often co-exist along environmental gradients, making
them a useful model for identifying dominant trade-off axes and their stability within a …

To understand the drivers of variation in digestive performance and their effects on growth,
we examined relationships among food consumption, digestive metabolism, food …

In salmonids, there seems to be a positive correlation between standard metabolic rate and
growth rate under artificial rearing conditions. Several recent studies have suggested that …

Standard metabolic rate (SMR) and active metabolic rate (AMR) are two fundamental
physiological parameters providing the floor and ceiling in aerobic energy metabolism. The …

Metabolism defines the energetic cost of life, yet we still know relatively little about why
intraspecific variation in metabolic rate arises and persists. Spatio-temporal variation in …

Phenotypic flexibility in physiological, morphological and behavioural traits can allow
organisms to cope with environmental challenges. Given recent climate change and the …

The correlated responses in feed intake and G: F ratio with selection for increased growth
rate were evaluated by comparing selected (S) and control (C) brown trout (Salmo trutta) …

Three gilthead sea bream families representative of slow, intermediate and fast heritable
growth in the Spanish PROGENSA® selection program were used to uncover the effects of …

Standard metabolic rate (Rs) and critical swimming speed (Ucrit) were used to assess the
aspects of physiological status (stamina) of rainbow trout Oncorhynchus mykiss. Fish were …
