“…That positive size-depth relationships may partially reflect the associated temperature gradient also accounts for the occurrence of positive size-depth relationships over a much narrower depth range in freshwater fish (Helfman 1978, McCauley & Huggins 1979, Power 1984. In freshwater there are often temperature gradients within a few meters in depth similar to those present in the sea over hundreds of meters.…”

“…Large fish show greater preference for colder waters than small fish of the same species (Magnuson et al 1979, McCauley & Huggins 1979, Jobling 1981. Accordingly, early life stages live in warmer waters, where food supply and growth rates are often greater (e.g.…”

We examined data on size of dominant demersal fish species in the SE Atlantic (44 species) and the NW Mediterranean (31 species) to determine whether there is a general tendency to increasing size towards deeper waters. Our results demonstrate significant positive size-depth relationships for most species examined (63 % SE Atlantic and 74 % NW Mediterranean). The relationships examined involved both a tendency towards greater size with ~ncreasing depth and a tendency towards smaller size towards shallower bottoms. The average ( * standard error) rate of increase in fish length with increasing depth was found to be 0.09 f 0.01 cm length (m depth)-' for the SE Atlantic species and 0.06 k 0.007 cm length (m depth)-' for the NW Mediterranean species. In addition, we found the slope and intercept of these relationships to scale approximately to the 3/4 power of the maximum and minimum fish size respectively, showing that interspecific differences in the nature of this relationship depend on the size range of the different species. Consideration of several hypotheses to account for this general pattern suggests that it reflects a migratory (or diffusive) movement towards deeper waters during ontogeny, where fish benefit from the extended Lives and lower metabolism at lower temperatures. We suggest this pattern is evolutionary In nature, and due to inherited behaviour.

“…Salmonids have adapted to exploit the cold water habitats created by retreating glaciers, despite the fact that optimum temperatures for maximum cardiac performance, aerobic scope and swimming ability are commonly around 15-18°C and preferred temperatures typically range from 12 to 18°C (McCauley and Huggins, 1979;Jobling, 1981). Thus, it is perhaps not surprising to find that cardiac function in rainbow trout has a rather low sensitivity to temperature change.…”

Cardiac plasticity in fishes: environmental influences and intraspecific differences

With over 20·000 species of teleost fish, considerable interspecific diversity in cardiac anatomy and physiology is expected. This is the outcome of evolutionary adaptation to different habits, modes of life and activity levels. For example, athletic species have a more powerful heart than sedentary species, and fish such as hagfish, carp and eel normally show a much higher degree of myocardial hypoxia tolerance than species such as salmonids (Farrell, 1991;Farrell and Jones, 1992). Plasticity in cardiac form and function has also been demonstrated during ontogeny, and the cardiovascular flexibility exhibited during embryonic and larval development, is nicely reviewed by Pelster (2003). What is less well appreciated, however, is the high degree of intraspecific cardiac plasticity displayed by post-larval fishes. Accordingly, this review explores what is known about intraspecific cardiac plasticity among juvenile and adult fishes. This intraspecific plasticity, like that exhibited during development, may well reflect individual variability on which natural selection could act.In this review, we focus primarily on temperature effects, which are relatively well studied, and on the effects of other environmental and biological factors that modify cardiac anatomy and physiology, including food deprivation, sexual maturation, exercise training and rearing under aquaculture conditions. Further, we summarize recent work on cardiac preconditioning and myocardial hypoxia tolerance in fishes, and discuss the potential implications of this work.Preconditioning is a short-term form of cardiac plasticity that has the potential to protect the heart from insults that might normally lead to cardiac damage, dysfunction or death. Preconditioning has been the focus of several thousand mammalian studies (e.g. see review by Yellon and Downey, 2003), and so the handful of recent studies in fish, which already point to important intraspecific differences, may find application outside the piscine world. Similarly, researchers who wish to stimulate cardiac growth to replace damaged myocardial tissue in mammals, may be heartened to discover that fish cardiac tissue, unlike the mammalian heart, does not lose its ability for hyperplastic growth with age. In fact, we suspect that the high degree of intraspecific plasticity that we Fish cardiac physiology and anatomy show a multiplicity of intraspecific modifications when exposed to prolonged changes in environmentally relevant parameters such as temperature, hypoxia and food availability, and when meeting the increased demands associated with training/increased activity and sexual maturation. Further, there is evidence that rearing fish under intensive aquaculture conditions significantly alters some, but not all, aspects of cardiac anatomy and physiology. This review focuses on the responses of cardiac physiology and anatomy to these challenges, highlighting where applicable, the importance of hyperplastic (i.e. the production of new cells) vs hypertrophic (the enlargement of existing cells...

The optimum temperature for fish growth is usually higher than the temperature the species encounter in nature (Imsland et al, 1996;Jonassen et al, 1999), and is stage-specific with juveniles preferring higher temperature to adults (McCauley and Huggins, 1979;Pedersen and Jobling, 1989). Increased temperature, in some aspect, can be advantageous for aquaculture production.…”

Aquaculture is challenged by a number of constraints with future efforts towards sustainable production. Global climate change has a potential damage to the sustainability by changing environmental surroundings unfavorably. The damaging parameters identified are water temperature, sea level, surface physical energy, precipitation, solar radiation, ocean acidification, and so on. Of them, temperature, mostly temperature elevation, occupies significant concern among marine ecologists and aquaculturists. Ocean acidification particularly draws shellfish aquaculturists' attention as it alters the marine chemistry, shifting the equilibrium towards more dissolved CO 2 and hydrogen ions (H + ) and thus influencing signaling pathways on shell formation, immune system, and other biological processes. Temperature elevation by climate change is of double-sidedness: it can be an opportunistic parameter besides being a generally known damaging parameter in aquaculture. It can provide better environments for faster and longer growth for aquaculture species. It is also somehow advantageous for alleviation of aquaculture expansion pressure in a given location by opening a gate for new species and aquaculture zone expansion northward in the northern hemisphere, otherwise unavailable due to temperature limit. But in the science of climate change, the ways of influence on aquaculture are complex and ambiguous, and hence are still hard to identify and quantify. At the same time considerable parts of our knowledge on climate change effects on aquaculture are from the estimates from data of fisheries and agriculture. The consequences may be different from what they really are, particularly in the temperature region. In reality, bivalves and tunicates hung or caged in the longline system are often exposed to temperatures higher than those they encounter in nature, locally driving the farmed shellfish into an upper tolerable temperature extreme. We review recent climate change and following environment changes which can be factors or potential factors affecting shellfish aquaculture production in the temperate region.
