Abstract
Fish reproduction in natural environments tends to occur in conditions, including extreme pH values, ideal for the survival of offspring. In this context, the purpose of this study was to assess the influence of pH on both survival and early development of two fish species, Astyanax lacustris (short-distance migrating fish) and Piaractus mesopotamicus (long-distance migrating fish), with different reproductive strategies. Our experiments were divided into two tests (incubation and larviculture) at five pH levels. First was incubation through a water recirculation system using 2 L incubators followed by larviculture using a 2.5 L aquarium. pH had no influence on the hatching rate of A. lacustris eggs, but affected the yolk-sac diameter, while the newly-hatched larvae had some skeletal disorders. For P. mesopotamicus, pH influenced the hatching rate and perivitelline space, while the newly-hatched larvae had several skeletal disorders. The larviculture of A. lacustris revealed no effect on the survival rate, but the analyzed morphometric variables indicated significant differences between the treatments. An acidic pH negatively influenced the survival rate of P. mesopotamicus, and all morphometric variables also varied significantly between the treatments. We concluded that both the survival and development of A. lacustris and P. mesopotamicus revealed different responses at pH levels during incubation and larviculture tests.

Abstract
For the 2 years of farming, at the indoor circulating aquaculture system, four kinds of skeletal deformities were found among 60 Far Eastern catfish, Silurus asotus. Deformities saw jawbone's luxation, abnormality of upper lip and malocclusion. Spinal deformity was most fatal deformities with low weight and small length. Jawbone's luxation had 1 maxilla and 2 mandibles. Abnormality of upper lip had just lip was back over. Malocclusion's left maxilla and right maxilla were not balanced. This experiment was any deformities in this species through the deformity can grasp how it affects.

Abstract
In order to identify biomarkers of oil pollution in fish we tested the effects of an experimental Light Cycle Oil (LCO) exposure on vertebral bone of sea bass, Dicentrarchus labrax L. A total of 60 adult fish were acclimated for fifteen days, then twenty were collected as controls (Day 0) while 40 were exposed to a soluble fraction of LCO (1136 ng L(-1) of ten Polycyclic Aromatic Hydrocarbons, PAHs) for seven days. Twenty of them were sampled at the end of the exposure period and the twenty last after a recovery period of fourteen days in clean seawater. Vertebral abnormalities were counted and bone mineralization, total bone area and bone density profiles were established for several post-cranial and caudal vertebrae. In sea bass, seven days of LCO exposure did not affect the frequency and severity of the vertebral abnormalities. No significant differences were observed in bone density and bone repartition (parameters of bone area profiles) between unexposed (Day 0), exposed (D7) and decontaminated (D21) fish. In contrast, bone mineralization of the vertebrae decreased in contaminated sea bass, but in a reversible way, which confirms a previous study in trout showing that this parameter is an early stress indicator. Our results suggest that vertebral bone mineralization could be used as a biomarker of PAH pollution in sea bass. It would be interesting to check this new biomarker in other teleost species exposed to various xenobiotics.

Abstract
Geographic variation in maternal investment in offspring size can be adaptive if differences in investment translate into improved offspring performance in the given environments. We compared two moor frog, Rana arvalis, populations in the laboratory to test the hypothesis that investment in large eggs in populations originating from stressful (acid) environments improves offspring performance when reared in stressful (acid) conditions. We found that large initial size (hatchling mass) had moderate to strong, environment-dependent positive effects on larval and metamorphic traits in the acidic origin population, but only weak effects in the neutral origin population. Our results suggest that interactions between environmental conditions and initial size can be important determinants of individual performance, and that investment in large eggs is adaptive in acid environments. These findings emphasize the role of maternal effects as adaptations to environmental stress.

Abstract
The fertilization rate and extent of the cortical reaction of anadromous whitefish decreased with increasing acidity (0.034 mmol Ca(2+)L(-1)); at pH 4.5 the fertilization rate was 46% of that at pH 6.5. Aluminum (250 microg L(-1)) decreased the percentage fertilization independently of pH and reduced the cortical reaction magnitude at all pH levels. In eggs at pH 5.0, especially at pH 4.5, and in solutions with Al, the growth of embryos was impaired by a perivitelline space that was too narrow. The proportion of embryos with a curved tail tip and those with blood circulation failure increased with decreasing pH. No fry hatched at pH 4.5 and those few that hatched at pH 5.0 did not survive. No fry survived Al-containing water at pH 5.5 and survival was decreased at pH 6.5 with Al. It is concluded that for successful recruitment of anadromous whitefish, pH should preferably remain >5.5 in dilute soft water when toxic concentrations of Al are present.
