“…The second is that temperature in early life affects body shape (Georgakopoulou et al 2007; personal unpublished results) and meristic count (Blaxter 1991;Georgakopoulou et al 2007; personal unpublished results). Georgakopoulou et al (2007), concluded that European sea bass juveniles reared in 15°C had more slender bodies than the ones reared in 20°C, a fact that could explain the higher swimming performance of the former as observed by Koumoundouros et al (2009).…”

Effect of developmental temperature on swimming performance of zebrafish (Danio rerio) juveniles

It is widely known that water temperature affects the swimming capacity of fish. But the effect of the rearing temperature on the swimming ability of the fish at later stages, has not had similar attention. In this study, four populations of zebrafish, were reared in different water temperatures (22, 25, 28 and 31°C) and after being acclimatized in a common temperature (26.5°C) for over a month, they were subjected to swimming trials in order to evaluate the maximum relative critical velocity (RU crit ) in each case. Fish that were reared in 22°C showed statistically significant lower performance than the ones reared in 31°C (7.72 ±0.17 vs. 8.79±0.28, means ± S.E.). Possible explanations for the observed differentiation could be the effect of early life temperature on fish muscle ontogeny or on body shape.

“…Larval size at hatch is generally influenced by incubation temperature (Chambers 1997;Blaxter 1992) and larval length at hatch is an important parameter which influences initial locomotion performances such as swimming speed, escape response and predator avoidance (Blaxter 1992). However, in some cases larger larvae experienced higher vulnerability to predation pressure compared to conspecifics at the same age with smaller body size (Litvak and Leggett 1992).…”

“…This event coincided well with mouth gap opening (this study ;Alshuth 1988;Shields 1989). A functional visual system is also a prerequisite for successful feeding and improved predator avoidance (Blaxter 1992;Fuiman 2002). This ontogenetic event is positively related to increasing temperature.…”

“…eggs and larvae, are strongly influenced by abiotic factors such as temperature, salinity, oxygen or wind forcing (Grauman and Yula 1989;Blaxter 1992;Köster et al 2003). Temperature plays a central role due to its importance in controlling physiological processes (Blaxter 1992;Fuiman 2002). The exact timing of critical transitions during early life history is extremely important for larval survival and thus the success of a cohort.…”

The influence of temperature on the development of Baltic Sea sprat (Sprattus sprattus) eggs and yolk sac larvae

et al. 2008

In spring 2004 and 2005 we performed two sets of experiments with Baltic sprat (Sprattus sprattus balticus Schneider) eggs and larvae from the Bornholm Basin simulating ten different temperature scenarios. The goal of the present study was to analyse and parameterise temperature effects on the duration of developmental stages, on the timing of important ontogenetic transitions, growth during the yolk sac phase as well as on the survival success of eggs and early larval stages. Egg development and hatching showed exponential temperature dependence. No hatching was observed above 14.7°C and hatching success was significantly reduced below 3.4°C. Time to eye pigmentation, as a proxy for mouth gape opening, decreased with increasing temperatures from 17 days post hatch at 3.4°C to 7 days at 13°C whereas the larval yolk sac phase was shortened from 20 to 10 days at 3.8 and 10°C respectively. Maximum survival duration of non-fed larvae was 25 days at 6.8°C. Comparing the experimental results of Baltic sprat with existing information on sprat from the English Channel and North Sea differences were detected in egg development rate, thermal adaptation and in yolk sac depletion rate (YSDR). Sprat eggs from the English Channel showed significantly faster development and the potential to develop at temperatures higher than 14.7°C.North Sea sprat larvae were found to have a lower YSDR compared to larvae from the Baltic Sea. In light of the predictions for global warming, Baltic sprat stocks could experience improved conditions for egg development and survival.

“…However, at one temperature the final mass may owe more to hypertrophy, at another temperature it may owe more to hyperplasia. Curiously, however, in the four species investigated so far temperature exerted opposite effects of muscle growth in the embryos (Blaxter, 1992): in plaice Pleuronectes platessa L., and herring Clupea harengus L. the lower temperature stimulated hypertrophy, the higher temperature hyperplasia, whereas in salmon Salmon salar L. and whitefish, the object of the present study, the opposite was the case (Fig. 4).…”

The temperature relationship of routine metabolic rate (R r ) of non-feeding, non-growing Coregonus lavaretus larvae between 2 and 15 C is characterized by Q 10 -values ranging from 1·8-2·45. The rate of growth, based on weight determinations, of first-feeding larvae amounted to 3·5, 7·6 and 9·4% day 1 at 5, 10 and 12 C respectively, from which Q 10 -values between 4·0 and 4·8 can be calculated. The rate of increase of muscle mass between 5 and 10 C, based on the determination of the cross-sectional area of inner muscle fibres, resulted in a Q 10 -value of 4·5. Water temperature influenced the pattern of growth of the inner muscle fibres. At hatching, after 360 day degrees, total muscle mass of larvae reared at 4 and 8 C was independent of temperature, but at 4 C the rate of mass increase owed more to hyperplasia (increase in fibre number) than to hypertrophy (increase in fibre mass), whereas at 8 C the opposite was the case. The calculation of power budgets (including the metabolic cost of growth) of first-feeding larvae yielded net conversion efficiencies (K 2 ) increasing with temperature from 46·3% at 5 C to 54·7% at 12 C. Comparing our data with literature data two general conclusions can be drawn. (1) In first-feeding larvae the net, but not the gross, conversion efficiency of food energy increases with temperature. This is due to net energy input being characterized by a much higher Q 10 -value than energy expenditures. (2) In embryos of freshwater fish so far investigated hyperplasia plays a greater role in the increase of fibre mass than hypertrophy at the lower temperature, whereas in embryos of marine fish hyperplasia prevails at the higher temperature. It is suggested that this discrepancy correlates with the high concentration of free amino acids in the eggs of marine species which provide an additional, easily available, source of metabolic energy absent in freshwater species. 1996 The Fisheries Society of the British Isles
