“…Gozlan et al (1999) mention breeding sofie in an aquarium at 6°C with an incubation period of 8 days. The latter authors (Gozlan et al, 1999) observed larval growth in the natural environment at temperatures ranging between 14°C and 18°C. The range of optimum temperatures for the adult stage falls between 16°C and 25°C (Gozlan, 1998).…”

The effects of industrial cooling water on fish communities were widely debated at the end of the seventies, when large thermal power plants were being developed. This led to numerous research programs on thermal tolerance in fish. The recent warming climatic period and especially the 2003 heat wave have brought thermal biology back to center stage. The work presented here has consisted in analyzing historical and contemporary literature to update basic knowledge on thermal tolerances of 19 riverine fish species. These data were then validated and completed by European fish specialists. We finally proposed a synthesis, based on more than 300 references, which details thermal tolerances for the entire life cycle: reproduction, embryonic, larval, juvenile and adult life stages. This updated material is of great importance to an understanding of the trends observed in fish communities or for forecasting future behavior in climate change scenarios. RÉSUMÉSynthèse des tolérances thermiques des espèces de poissons communes des rivières et fleuves de plaine de l'ouest européen L'effet de l'élévation de température des cours d'eau a été largement débattu à la fin des années 70 qui ont connu le développement des centrales thermiques de grande puissance. Ces études ont généré alors de nombreux programmes de recherche sur la tolérance thermique des poissons, dont les résultats sont parfois oubliés ou difficiles à rassembler. Le réchauffement climatique actuel et en particulier l'épisode caniculaire de 2003 a mis de nouveau ce thème sur le devant de la scène. Le travail de synthèse présenté a consisté à analyser des données historiques et contemporaines de la littérature, afin de mettre à jour les connaissances de base sur les tolérances thermiques de 19 espèces de poissons d'eau douce. Cette synthèse a ensuite été validée et complétée par des spécialistes européens. Elle s'est appuyée sur plus de 300 références qui détaillent les tolérances thermiques de chacun des stades du cycle de vie des espèces étudiées : reproduction et stades embryonnaire, larvaire, juvénile et adulte. Cette mise à jour est essentielle pour comprendre les tendances d'évolution déjà constatées des communautés de poissons et prévoir les futures évolutions en fonction de différents scénarios de changement climatique.

“…Adjusted corporal measurements are good indicators of changes in allometric relationships, since they are calculated assuming a constant RC, and a change in the RC produces errors of opposite sign before and after the breakpoint. This is an approach equivalent to plotting the residuals of double logarithmic regression as carried out by Gozlan et al (1999), Kovac et al (1999), andSimonovic et al (1999).…”

Galaxiids are present in many of the Andean lakes in southern South America. We studied landlocked Galaxias maculatus (Jenyns) and Galaxias platei Steindachner populations in a deep oligotrophic lake (Lake Gutiérrez, Patagonia, Argentina). Their temporal and spatial distribution, intralacustrine movements (horizontal and vertical), and spawning periods were analysed using several sampling techniques (ichthyoplankton net, seine net, gill net, and baited benthic taps). We identified the early life stages of both species based on their morphology and otolith shape. The free embryos of both species migrate to the limnetic zone, where they coexist as larvae, facing the same food availability and probably the same predation risk. Each species then moves on to its own juvenile and adult habitat: the littoral and benthic zone for G. maculatus and only the deeper benthic zone for G. platei. Their adult habitats and part of their spawning periods partly overlap.

“…The formation of scales in teleost fishes often occurs during the larval-juvenile transition (Ahlstrom et al 1976;Kendall et al 1984;Gozlan et al 1999;Webb 1999;Urho 2002). Thus, the timing of scale formation may be a useful indicator, among others, of the completion of the larval period and the beginning of the juvenile period, a matter of considerable discussion (see above and Fuiman 1997;Fuiman et al 1998).…”

Patterns of scale formation (onset, points of origin, completion, and spatial pattern) were examined for six species of killifishes in two families (Cyprinodontidae: Cyprinodon variegatus, and Fundulidae: Fundulus confluentus, F. heteroclitus, F. luciae, F. majalis, and Lucania parva) to determine if the patterns are another useful indicator for the transition from the larval to juvenile periods. In some species, the patterns were very similar, with scale formation originating on/near the caudal peduncle, then the dorsal surface of the head (in fundulids only), and later on the lateral surfaces of the head, and on the ventral surface of the trunk at the level of the pectoral fin. The timing of scale formation, relative to fish size, was later than or overlapped with other morphological characters (e.g., fin ray formation, juvenile/adult body shape) often used to mark the larval/juvenile transition. The onset of scale formation, across all species, occurred between 8 and 13 mm TL. Completion of scale formation occurred between 18 and 23 mm TL. At completion, scales covered 86-99% of the trunk and head. Completion of scale formation in these fishes is one of the last external morphological changes to occur during the larval to juvenile transition. For these species, and other flatfishes we have examined in detail, it appears that scale formation may be useful in helping to define the end of the larval period and the beginning of the juvenile period. Further studies, of divergent groups of teleosts, are necessary to determine if this length-based approach has broad validity.
