Two egg batches of spotted wol⁄sh, Anarhichas minor Olafsen, were incubated at 4, 6 and 8 1C. Embryo samples were ¢xed and compared on each100th daydegree until hatching (up to 1000 daydegrees). Embryos, yolk sacs and chorions were dissected and the sizes, wet and dry weights were recorded separately. Comparisons of gross morphologies and measured parameters showed increasing and generally signi¢cant di¡erences with time between the incubation temperatures. Lower temperatures produced longer and more di¡erentiated larvae at hatch with a smaller yolk sac. Even though some unexpected deviations were registered among batches and experimental groups, it was clear that temperature affected embryo survival and time of hatching. Overall survival was best at 6 1C, in agreement with results from earlier studies.Yolk conversion e⁄ciencies measured around the hatching point were generally high, ranging from 60% to 78%, varied between the two batches and probably re£ected the developmental variations between embryos and larvae at the respective ages (daydegrees). The hatching process was apparently an energy-demanding period; yolk conversion e⁄ciencies of unhatched embryos of similar age at each temperature were always higher. Temperature is one environmental factor that can be manipulated in hatcheries to induce hatching of viable larvae at an optimal stage of di¡erentiation with respect to ¢rst-feeding success and early survival.

“…Finally, in the striped snakehead Channa striata (Arul 1991) and the lake minnow Rhynchocypris percnurus (Kaminski et al 2006), the body size at yolk exhaustion was slightly longer at cold than at warm temperatures whereas an opposite trend was observed for the fish dry body mass. This brief review highlights the difficulty of predicting whether temperature have a positive, neutral or negative effect on YUE and fish size, although these aspects can be crucial, both in an ecological and in an aquacultural context.…”

“…3b), at least on the basis of body length. The dry body mass of fish was not measured here, so it is uncertain whether temperature-dependent differences in body length were accompanied with similar differences in dry mass, or if the water content of the fish was inversely proportional to temperature, as was observed in several fish species (Arul 1991;Kaminski et al 2006). In clown loach, the size difference after yolk absorption at different temperatures is quite tenuous (5.7 against 5.5 mm TL at 23 and 32…”

-The knowledge of how fish survive and grow at different temperatures, and how these traits vary between life stages, is essential to evaluate the effects of climate change on wild fish and implement effective strategies in aquaculture. These issues are addressed in this study through a series of experiments that evaluate the effect of temperature (23−34• C) on the embryos and larvae of clown loach, Chromobotia macracanthus. This species is endemic to the rivers of Sumatra and Borneo, highly praised on the ornamental fish market, and has been reproduced in captivity recently. No embryo survived a 24-h exposure to 34• C until the age of 3 days after hatching (dah); mortality was high at 32• C at 2 and 3 dah, whereas it was low and similar from 1 to 4 dah at 23−29• C (<10%). Yolk absorption was proportional to water temperature (Q 10 • C of 1.69 in the 23−32• C range), but fish reared at cold temperatures were larger than others at the start of exogenous feeding (5.7 vs. 5.5 mm TL, at 23 and 32• C, respectively). The survival of larvae fed Artemia nauplii ad libitum was high at 23−32• C (80−100%), but almost null at 34 • C. Growth models at different temperatures were produced from weekly measurements in two experiments, and tested by comparing their predictions with the results of a third experiment. Throughout the larval stage, the optimal temperature for growth (T • opt are encouraging perspectives for the aquaculture of clown loach. From an ecological perspective, the species has an atypical thermal biology, as it is less thermophilic than other tropical fishes, but more stenothermal than temperate fishes exhibiting similar values of T • opt , both traits being of particular concern in the context of global warming.

“…There is a significant inverse relation between incubation temperature and time to hatching and first feeding and the yolk utilization rates in fish (May 1974;Polo et al 1991;Hardy & Livak 2004;Y ufera et al 2011). However, there is not a direct relation between yolk absorption efficiency and temperature (Laurence 1973;Arul 1991;Polo et al 1991). Yolk efficiency has been calculated as the length or mass attained by the embryo after the complete yolk reabsorption in relation to yolk volume.…”

Teleost fish are more diverse than any other vertebrate group, and yet only a limited number of species are fished and farmed globally. Efforts to expand the quantity and diversity of fish produced are hampered by the extreme diversity of ontogenetic responses of fish, especially during larval development. This review looks at advances in molecular phylogeny, endocrine and nutrient influences and long-term studies of the phenotypes of commercially important fish to put the sources and consequences of this plasticity into context. This nested context of evolutionary forces of the fish-specific genome duplication, epigenetic influences, ontogenetically conserved processes like metamorphosis and cell determination is further presented in relation to how fish larvae translate the environment into somatic signals, the teleostian diversity of internal processes like sex differentiation and somatogenesis, and the long-term practical consequences of changes in timing or anthropogenic influences. This review aims to present a new baseline of knowledge of marine fish larvae which is useful to scientists, managers and producers.
