“…We also expected some somatic growth of whitefish at the low temperature treatment (1°C), but whitefish instead lost weight in the first period of the experiment. Whitefish at the higher temperature treatments (3 and 6°C) exhibited low but slightly positive growth; a result that is comparable with the findings of similar studies carried out on Lake whitefish (Edsall, 1999).…”

This comparative study explores how low temperatures affect the mortality and growth of first generation hatchery-reared progeny of subarctic populations of Arctic charr (Salvelinus alpinus L.) and European whitefish (Coregonus lavaretus L.). Replicate fish groups where held under simulated natural light regimes (70°N) at three constant temperatures (1, 3 and 6°C). The mortality of Arctic charr was low (B1.4%) at all temperature treatments, whereas the mortality of whitefish increased with decreasing temperature from 6% at 6°C to 33% at 1°C. The Arctic charr exhibited higher growth rates than whitefish at all three temperature regimes. All groups of Arctic charr increased in weight, whereas whitefish held at 1°C did not gain weight throughout the experimental period of 133 days. Arctic charr exhibited a large intraspecific variability in growth leading to large variations in size-structure, whereas whitefish in contrast showed very homogenous growth and size-structure patterns; a dissimilarity probably related to species-specific differences in antagonistic behaviour. Evidently, Arctic charr are more cold water adapted than whitefish and are able to maintain growth at extremely low temperatures. Arctic charr thus appear to be the most suitable species for aquaculture at low water temperatures.

“…Whitefish are also able to feed during winter periods (Tolonen, 1999;Gerdeaux et al, 2002). The related North-American Lake whitefish (C. clupeaformis) are found to have positive growth at 5°C (Edsall, 1999), but no such information is known for the European whitefish.…”

“…The question is what factor was responsible for these differences in growth rate. Temperature is responsible for increasing growth rates (Elliott, 1982), but only within the optimum window (Larson & Berglund, 1998;Edsall, 1999;Steinarsson & Bjö rnsson, 1999). In the present research, as larvae from the third, slowest growing cohort experienced the highest temperatures (17·6 C), it suggests that there was an inverse relationship between larval growth and temperature.…”

Differences in temperature conditions and somatic growth rate of larval and early juvenile spring‐spawned herring from the Vistula Lagoon, Baltic Sea manifested in the otolith to fish size relationship

Larval and juvenile herring Clupea harengus collected in the Polish part of the Vistula Lagoon in May-July 1997 had hatched between 17 April and 9 June and originated from three cohorts. The spawning season began on 1 March at 3·8 C and was completed on 3 June at 12·7 C. Mortality among larvae was high in the first 2 weeks of April, probably associated with significant temperature decrease at the beginning of the spawning season. The growth of 10-48 mm L S herring was linear, highest for larvae and juveniles from the first cohort (0·58 mm mm 1 day 1 ), slower for the second cohort (0·55 mm mm 1 day 1 ) and the slowest for the third cohort (0·45 mm mm day 1 ). Temperature effects on the growth were inconclusive and potentially unfavourable feeding conditions in June might have been responsible for the relatively slow growth of third cohort larvae and juveniles.Relationships between otolith size (perimeter, length, width, area, and weight) and fish size (L S ) differed among the three cohorts, related mostly to the positive temperature effect on otolith growth, individuals growing in warmer water had larger otoliths. Although a negative growth rate effect was observed as well, it was less significant. 2001 The Fisheries Society of the British Isles

“…Temperate poikilothermic fishes are less active during the cold winter period than in summer (Heggenes et al 1993), and most fishes cease growing during winter period in Arctic and subarctic lakes (Magnuson et al 1979;Edsall 1999). Consequently, their metabolic demands for food decrease (Mookerji et al 1998;Fiogbe & Kestemont 2003).…”

The effects of winter ice cover on the trophic ecology of whitefish (Coregonus lavaretus L.) in subarctic lakes

Lakes in Arctic and subarctic regions display extreme levels of seasonal variation in light, temperature and ice cover. Comparatively little is known regarding the effects of such seasonal variation on the diet and resource use of fish species inhabiting these systems. Variation in the diet of European whitefish Coregonus lavaretus (L.) during periods of ice cover in this region is often regarded as ‘common knowledge’; however, this aspect of the species' ecology has not been examined empirically. Here, we outline the differences in invertebrate community structure, fish activity, and resource use of monomorphic whitefish populations between summer (August–September) and winter (February–March) in three subarctic lakes in Finnish Lapland. Benthic macroinvertebrate densities did not exhibit measurable differences between summer and winter. Zooplankton diversity and abundance, and activity levels of all fish species (measured as catch per unit effort) were lower in winter. The summer diet of C. lavaretus was typical of a generalist utilising a variety of prey sources. In winter, its dietary niche was significantly reduced, and the diet was dominated by chironomid larvae in all study sites. Pelagic productivity decreases during winter, and fish species inhabiting these systems are therefore restricted to feeding on benthic prey. Sampling time has strong effect on our understanding of resource utilisation by whitefish in subarctic lakes and should be taken into account in future studies of these systems.
