“…In addition, there have been reports since the early 90s of a wide spread occurrence of embryonic deformities in pelagic eggs of several fish species in coastal waters in the North Sea (Cameron et al, 1992). However, it is not yet clear whether these fluctuations reflect exposure to endocrine disrupters or other toxicants or may be caused by factors such as temperature (Cameron et al, 1992). These results showed that sewage effluent and chemicals could cause lesion of fish embryos.…”

To develop the whole effluent toxicity testing methods (WET), embryo larval stage toxicity test using Japanese medaka (Oryzias latipes) was conducted to evaluate an effluent from a banknote printing plant (BPP). The method is based on acute toxicity using endpoint of 96-h larval morality and on chronic toxicity using endpoints such as the time to hatch, hatching success, deformity, growth rate, swim-up failure, accumulative mortality and sexual ratio. In test for 96-h larval mortality, LC50 (the concentration was lethal to 50% of newly hatching medaka larvae) was 72.9%. In chronic toxicity test, newly fertilized embryos (b 5-h old) were exposed to 1%, 6.25%, 12.5%, 25%, 50% effluent concentrations and to 200 Ag/l BPA in a 24-h static renewal system at 25 F 1 8C until 15 day post-hatch. The results showed that all chronic endpoints were significantly different from the control at 50% dilution ( p b 0.01). Embryos began to show lesions on 4th day at higher concentrations (12.5%, 25%, 50% BPP effluent concentrations). Treatment group of 25% dilution showed delayed time to hatch. A reduction in body weight was observed at 25% dilutions for males and females, respectively. Deformities were observed in newly hatched larvae at 25% and 50% BPP effluent concentrations. At 25% dilution, sex ratio of larvae was alternated and there was feminization phenomenon. We conclude that embryo larval stage test using medaka is feasible to evaluate both acute and chronic toxicities and potential endocrine disrupting activity of industrial effluents. D

“…Elevated levels of contaminants, including chlorinated hydrocarbons, in several other fish species are associated with reproductive impairment (Cameron et al 1992;Drevnick and Sandheinrich 2003;Hammerschmidt et al 2002;Longwell et al 1992), reduced egg viability (Billsson et al 1998;Giesy et al 1986;Mac and Edsall 1991;Matta et al 1997;Von Westernhagen et al 1981), reduced survival of larval fish (Berlin et al 1981;Giesy et al 1986), delayed maturity (Jorgensen et al 2004) and posterior malformations (Billsson et al 1998). Pesticide exposure in fish may affect antipredator and homing behavior, reproductive function, physiological development, and swimming speed and distance (Beauvais et al 2000;Moore and Waring 2001;Scholz et al 2000;Waring and Moore 2004).…”

“…Due to its important ecological impact, especially the influence on buoyancy needs further investigations. Cameron et al (1992) observed high degrees of malformation in eggs from the Southern and German Bight in 1987, while the 1986 samples showed a much lower degree of malformation. This was unexpected because the 1986 water temperatures were far below those of 1987.…”

“…Besides temperature, different environmental influences including UV-B radiation should have caused the differences in malformation. Generally, with 11% malformation plaice eggs always showed the lowest rates when compared with other species sampled during the winter surveys; during summer surveys sole eggs showed the lowest malformation rate (4%) of all species (Cameron et al, 1992).…”

Physical influences on the stock dynamics of plaice and sole in the North Sea

SUMMARY: A review of the literature on influences of physical factors on plaice and sole stresses the prominent role of water temperature in all life stages of the species. For plaice, e.g., water temperatures on the spawning grounds are inversely correlated with year-class strength, and growth depends primarily on temperatures. In many instances, however, direct and indirect effects are hard to disentangle and to quantify for use in models, e.g. for stock assessment and prediction (SAP). Hydrodynamic circulation influences the egg and larvae distributions. Existing models reveal the drift variability to be of the same magnitude as year to year variations of larval abundance just before immigration. An improved modelling of the processes could combine recent circulation and transport models incorporating physical/biological properties of the eggs and larvae. It is suggested that future research focuses on this approach. The course of irradiation during spring and its influence on mortality of the 0-groups of both species in the nursery deserves further studies if it is to be useful for SAP.
