“…The reason for faster hatching of embryos at higher temperatures is their increased mobility in warmer water and earlier excretion of the hatching enzyme. These characteristic behaviours of embryos incubated at higher temperatures were common in numerous fish species (Blaxter, 1969(Blaxter, , 1992Penaz, 1974;Kamler, 1992). Also in this study, after the application of thermal modification during the earliest stages of ontogenesis, developmental rate and time to hatch, hatching period duration and times required to reach a given ontogenic stage decreased as the temperature increased from an optimum to sublethal level.…”

“…On the other hand, the intake of exogenous food usually occurs at the lowest tolerated temperatures only after complete resorption of the yolk sac. This is undoubtedly related to the increased metabolism of fish in warmer water (Kamler, 1992;.…”

“…The rearing of young fish under controlled conditions is the more effective, the more precisely the influence of environmental conditions on the body -relatively sensitive at that time -is determined (Wolnicki, 2005). Temperature is the environmental factor with the largest influence on the development of fish (Herzig and Winkler, 1986;Kamler, 1992Kamler, , 2002Kupren et al, 2008a). Its influence on the incubation of dace, ide and chub eggs was described by numerous authors in their papers (Kennedy, 1969;Penaz and Sterba, 1969;Florez, 1972;Mills, 1980;Economou et al, 1991;Calta, 2000;Rechulicz et al, 2002).…”

In recent years, despite a certain deceleration of the process, evident decrease or even extinction of many local populations of the majority of rheophilic fish species including dace Leuciscus leuciscus (L.), ide L. idus (L.), and chub L. cephalus (L.) -the only representatives of the genus Leuciscus in Polish ichthyofauna -has still been observed. Invariably, the major reasons for that situation are ) and chub L. cephalus (L.) were obtained from rivers belonging to the Pasleka River basin (northeastern Poland) and next transported to a hatchery for the purpose of conducting artificial reproduction. The obtained eggs were fertilized and next incubated under a variety of thermal protocols: slow gradual heating of water (M1), rapid increase in temperature at the end of incubation (M2), fluctuating temperature (M3) and two constant temperatures (optimum and sublethal). Variable thermal changes of water were also continued after hatching, up to the yolk sac resorption by larvae. During the study it was shown that relative to incubation at optimal temperatures (12.3°C for dace, 15.7°C for ide and 19.0°C for chub), thermal modifications had no clear influence on a decrease in survival rates (differences among regimes did not exceed 5%) and increase in developmental deformations (differences below 1.0%) observed among the hatched embryos. The duration of egg incubation and developmental rate increased with increasing temperature. In the systems with modified temperature the embryonic development of dace (from fertilisation to commencement of exogenous food intake) took from 9.5 to 22.5 days, for ide from 6.1 to 12 days and for chub from 5.0 to 10.5 days. The yolk sac resorption stage in the particular species occurred from 11.7 to 23 days for dace, 7.5 to 13.2 days for ide and 5.5 to 12.8 days for chub. Different time of hatching was also reflected in the level of ontogeny of hatched embryos. Among the fish hatched at modified temperatures the largest sizes, similar to those characteristic of fish incubated at optimum temperatures, were observed in individuals originating from variants where the temperature fluctuated. The developmental disproportions among the embryos of studied species originating from different thermal regimes observed at the time of leaving the egg shells were definitely larger than during the following development stages. This study also confirmed that the embryos of studied species can adapt to increasing water temperature due to global warming up to 19.0 (dace), 23.0°C (ide) and 27.5°C (chub). The obtained results are very important not only for practical purposes but also from physiological and ecological aspects.

“…All calculations were made on the basis of DM preferentially to WM, as the energy contents of small fish vary substantially with increasing fish size, essentially because of decreasing hydration (Kamler 1992), and estimations of growth or energy transformation on the basis of wet body mass frequently produce biases (Canale and Breck 2013). Analyses were done on a daily basis, because H. longifilis grows very rapidly, and the capacity for growth and conversion efficiency vary considerably with increasing body size, especially in small fish.…”

-This study relied on the day-by-day analysis of bioenergetics and prey size preference in isolated cannibals of the African catfish Heterobranchus longifilis (13-57 mm standard length, 3-500 mg dry body mass, n = 153) that were offered ad libitum conspecific prey of adequate sizes in small-sized (2-L) environments under controlled conditions (12L:12D, 30• C). In these conditions, cannibals of increasing body size selected preferentially prey of decreasing size relative to their own, and increasingly closer to the optimal prey size (producing the highest gross conversion efficiency). The role of experience in cannibalism was found of secondary importance relative to body size, both as regards food intake and prey size selectivity. These results indicate that in environments that minimize the escape capacities of their potential victims, as applies to most aquacultural contexts, fish exercising cannibalism tend to forage optimally, which has rarely been evidenced for piscivorous behaviour. The present study further highlights that H. longifilis possesses a very high capacity for growth, which originates from the combination of high food intake and very high conversion efficiency, and makes this species of utmost interest for aquaculturists wherever fast growth is desirable, but also extremely prone to cannibalism wherever feeding schedules are inadequate.

“…P som /C, or K 1 according to Ivlev (1945), where P som is rate of growth and C the rate of ingestion, can be represented by an asymmetric bell-shaped curve with the maximum somewhere in the upper half of the biokinetic temperature range of the species (Elliott, 1976;Brett, 1979;Brett & Groves, 1979;Wootton, 1990;Jobling, 1994). The steep increase of this function in the lower temperature range is due to the fact that the maximum rate of energy input, C max , rises more steeply with temperature than the maintenance rate of energy expenditure (R m ), causing an increase of the scope for growth (Brett, 1976;Kamler, 1992). The decrease of the function in the upper temperature range is due to C max reaching a ceiling value at a lower temperature, and dropping more steeply, than R m .…”

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
