“…Fish often face situations in nature where there is a potential tradeoff between increased feeding rate and reduced survival (Lima 1998;Mangel and Stamps 2001). For example, (i) open-water (pelagic habitats) may contain richer food resources but pose higher predation risk (e.g., Werner and Hall 1988;Gliwicz et al 2006), (ii) daytime foraging may yield a higher feeding rate but greater risk of predation than nocturnal foraging (e.g., Fraser and Metcalfe 1997;Metcalfe et al 1999;Ryer and Hurst 2008), and (iii) more active foragers may encounter more prey (or richer habitats) and grow faster but suffer higher mortality rates (e.g., Werner and Anholt 1993;Fraser et al 2001;Biro et al 2004Biro et al , 2006Sundström et al 2004). Fitness tradeoffs can also occur spatially (e.g., one area of a habitat favors one behavioral type, while another area favors a different one), temporally within generations (e.g., across development or across genetically linked behavioral traits), and temporally between generations (e.g., frequency-dependent selection).…”

Fish have proven to be model organisms for the study of animal personalities, and a rich literature documents consistent interindividual behavioral differences in a variety of species. However, relatively few studies have examined the ecological consequences of such consistent interindividual differences in behaviors in fish or other organisms, especially under field conditions. In this review and perspective, we discuss the factors that may lead to the formation and maintenance of behavioral types in fish populations. We then examine what is known about the effects of personality variation on individual growth and survival, breeding behaviors and reproductive success, habitat use, diet, and ontogenetic niche shifts, migration and dispersal, as well as potential consequences for species interactions and ecosystem functioning. We focus as much as possible on studies conducted under natural or seminatural conditions, as such field studies are most relevant to elucidating the ecological consequences of behavioral variation. Finally, we discuss the potential importance of consistent individual differences in behaviors to fisheries management and conservation, specifically examining consequences for recreational and commercial fishing, hatchery rearing, and stock enhancement.

“…It may also be necessary to account for the dependence of this interaction on body size, abiotic variables, and competitor or predator assemblages. In particular, very few studies have examined whether growth variation in YOY plaice is related to predation risk even though this factor may be a critical determinant of feeding and growth in young fishes such as YOY plaice (Burrows et al 1994, Burrows & Gibson 1995, Ryer & Hurst 2008. In addition, the extent to which spatial growth variation is driven by differences in growth performance through gen etic or non-genetic local adaptation requires testing.…”

Patterns and causes of spatial variation in RNA-predicted growth rates in mid-August were examined in young-of-the-year European plaice Pleuronectes platessa ('YOY plaice') at 22 beaches along a 300 km stretch of coastline in west Scotland in 3 consecutive years. According to restricted maximum likelihood models, growth rates varied among beaches (25 km scale), but these spatial patterns were not consistent across years. We found no evidence for spatial variation in growth at the scale of subregions (50 km) or regions (100 km). Growth rate was positively correlated with total length, both within and among beaches and years. In general, YOY plaice in mid-August grew more slowly than estimated ad libitum laboratory rates. Average growth rates by beach and year were inversely related to intraspecific competitor densities, but not interspecific competitor densities (brown shrimp Crangon crangon) or 2 environmental productivity metrics (nearshore chlorophyll a concentration and lugworm Arenicola marina cast density). Physical beach characteristics also explained a significant source of spatial growth variation, with fish growing faster at beaches with larger tidal range and wave fetch. Therefore, the hypothesis of sub-maximum growth due to intraspecific competition (density-dependent growth) was supported, but additional, previously unexplored processes related to physical beach characteristics appear to have important influences on the spatial growth dynamics of YOY plaice.
