“…Most research on the capacity for compensatory growth has examined responses to periods of food restriction or deprivation (Jobling et al 1994;Paul et al 1995;Sogard and Olla 2001). However, compensatory feeding and growth responses have also been observed after growth reductions resulting from oxygen depletion (Bejda et al 1992;Foss and Imsland 2002), delay in diet switch (Buckel et al 1998) or periods of relatively cold temperature (Mortensen and Damsgård 1993;Nicieza and Metcalfe 1997). However, the response in rates of feeding, growth and morphological condition to starvation and refeeding have been poorly documented in clupeids compared to other (mostly cyprinid and salmonid) fishes (e.g., Miglavs and Jobling 1989;Russell and Wootton 1992).…”

Despite their trophodynamic importance in many aquatic ecosystems, few studies have quantified the feeding-growth relationship of clupeid fishes. In laboratory trials, we quantified the relationship between rates of food consumption (C, % fish energy content (Joules d −1 )), somatic growth rate (G, % Joules d −1 ), and swimming speed (S S, body lengths (bl) s −1 ) for postlarval (30-to 50-mm standard length) European sprat (Sprattus sprattus L.) collected from the southwestern Baltic Sea. Measurements of G and S S were also made on groups before and after an abrupt shift in prey availability. Maintenance (0-growth) and maximum food consumption rates were 5.5 and 42 % somatic energy content d −1 , respectively. Mean±SE gross growth efficiency (K 1 =100 G C −1 ) was 26.9±3.0 %. Unfed postlarvae had markedly lower S S compared to continuously-fed fish (0.1 versus 0.5 to 0.7 bl s −1 ). After 10 days of re-feeding, one group of previously unfed fish was hyperactive (mean S S of 1.2 bl s −1 ) but no re-fed groups exhibited hyperphagia (based upon prey numbers), increased K 1 , or compensatory growth.Increased competition (relatively high S S ) was evident during feeding in fish maintained at low to moderate but not at ad libitum prey levels. Our findings provide estimates of prey resources required to fuel in situ growth and help characterize metabolic strategies of European sprat within variable feeding environments.

“…Growth compensation may, however, have occurred after the temperature was increased due to the previous temperature restriction. In earlier studies of compensatory growth after temperature manipulation in salmonid fish, growth compensation was complete in four [48], ten [49] and approximately 20 weeks [50]. In our study, the fish had 14 weeks to recover from the temperature restriction before the body size experiment started.…”

“…Fish that are forced to compensate for slow growth are found to demonstrate accelerated growth once conditions for growth improve, and these individuals are usually physiologically more efficient in processing energy. This metabolic advantage is usually relatively short-term in adult fishes, but has been shown to have lasting effects in early life history stages (Mortensen & Damsgård 1993, Ali et al 2003. While survivors appear to have the signature of growth compensation early in the larval stage, this growth appears to have enhanced survival in the juvenile phase.…”

Behavioural traits can strongly influence fitness and survival and are important mediators of life history trade-offs. This study explored the links between mortality trade-offs associated with fast growth during larval life and behaviour of individuals during an important life history transition. Longitudinal sampling of a cohort of damselfish settling on a reef at the end of their larval stage found that individuals with small otolith sizes at hatching and low otolith growth rates were selectively removed from the local population, while there was no apparent selection for size or body condition over the first 24 h after settlement. Selection against slow growth (initial larval growth and maximum growth) and small size at hatching and settlement were accentuated over the first month after settlement. Detailed behavioural assessments of naïve larvae settled onto habitat patches and monitored for 24 h found that initial boldness aided survival, but individuals that ventured larger distances from shelter suffered higher mortality. Correlations of growth with behavioural attributes were generally poor; however, there was a weak correlation between boldness and maximum growth. A measure of flexibility in the maximum distance ventured from shelter was positively related to initial otolith growth. Our results suggest that although early growth which is relatively slow leads to higher mortality later in life, and behavioural attributes influenced survival, there were only weak correlations between growth history and behaviour. This may be due to strong selective pressures on young fish to learn novel behaviours rapidly after settlement. Selection may promote behavioural flexibility at this key ecological transition.
