The turbot Scophthalmus maximus L. is a large teleost flatfish of the family Bothidae. Its range extends from the Adriatic (Faber, 1883) and Mediterranean (Morgan, 1956) northwards to the Norwegian coast, and includes the Baltic Sea and waters surrounding the British Isles. It has been recorded as far north as the Lofoten Islands (Fulton, 1905), and is taken occasionally at Faroe, Iceland and Rockall.

Abstract Turbot Scophthalmus maximus (Linnaeus, 1758) is a fish belonging to the Pleuronectiformes order. It is commonly observed in waters of the northern Atlantic, and also in the Baltic Sea. As an economically significant species, it is fished on an industrial scale, and also farmed in some European countries. Seventy-two turbots from the Gulf of Gdańsk (26th ICES zone) were examined for parasite presence in the years 2010-2012. The study revealed the presence of the tapeworm Bothriocephalus scorpii (Müller, 1776) and acanthocephalan Corynosoma semerme (Forssell, 1904). The overall (both parasites) prevalence of turbot infection was 100% with a mean intensity of 18.7. C. semerme is a parasite which has not been noted so far in turbot from the southern Baltic. The presence of C. semerme in turbot was emphasized in the context of possible infection of terrestrial mammals, including humans.

Abstract. The calcareous tubeworm Spirorbis spirorbis is a wide-spread serpulid species in the Baltic Sea, where it commonly grows as an epibiont on brown macroalgae (genus Fucus). It lives within a Mg-calcite shell and could be affected by ocean acidification and temperature rise induced by the predicted future atmospheric CO2 increase. However, Spirorbis tubes grow in a chemically modified boundary layer around the algae, which may mitigate acidification. In order to investigate how increasing temperature and rising pCO2 may influence S. spirorbis shell growth we carried out four seasonal experiments in the 'Kiel Outdoor Benthocosms' at elevated pCO2 and temperature conditions. Compared to laboratory batch culture experiments the benthocosm approach provides a better representation of natural conditions for physical and biological ecosystem parameters, including seasonal variations. We find that growth rates of S. spirorbis are significantly controlled by ontogenetic and seasonal effects. The length of the newly grown tube is inversely related to the initial diameter of the shell. Our study showed no significant difference of the growth rates between ambient atmospheric and elevated (1100 ppm) pCO2 conditions. No influence of daily average CaCO3 saturation state on the growth rates of S. spirorbiswas observed. We found, however, net growth of the shells even in temporarily undersaturated bulk solutions, under conditions that concurrently favored selective shell surface dissolution. The results suggest an overall resistance of S. spirorbis growth to acidification levels predicted for the year 2100 in the Baltic Sea. In contrast, S. spirorbis did not survive at mean seasonal temperatures exceeding 24 °C during the summer experiments. In the autumn experiments at ambient pCO2, the growth rates of juvenile S. spirorbis were higher under elevated temperature conditions. The results reveal that S. spirorbis may prefer moderately warmer conditions during their early life stages but will suffer from an excessive temperature increase and from increasing shell corrosion as a consequence of progressing ocean acidification.

AbstractThe main aim of the present study was to determine the effect of low salinity conditions (3 PSU and 7 PSU) on the hatching success, growth and mortality of Orconectes limosus. The results revealed that berried females survived exposure to salinities of 3 PSU and 7 PSU whilst incubating their eggs. The reproductive success reached 100% at both salinities. The length increment of young crayfish per molt was larger at 7 PSU than at 3 PSU — but their condition was affected by higher salinity. The mortality among juveniles reached approximately 50% within 5 weeks of hatching at both salinities.

<em>Abstract</em>.—The reproductive success of cod <em>Gadus morhua </em>from the Baltic Sea and the Barents Sea was compared. The offspring of 17 family pairs from the Baltic Sea and 12 family pairs from the Barents Sea were investigated during the embryonic and larval development stages. Frequencies of mortality over time and frequencies of different disorders at hatch were analyzed. The results indicated that the reproductive success of cod from the Baltic Sea was seriously impaired. The Baltic cod showed high mortality before hatch. In newly hatched larvae, different kinds of disorders were seen, such as vertebrae deformity, disrupted yolk sac or subcutaneous edema in the yolk sac, and precipitate in the yolk. To compare mortality and early developmental abnormalities in Baltic cod and Baltic salmon <em>Salmo salar</em>, the offspring of 20 salmon family pairs, caught in the River Dalälven in Sweden, were investigated analogically. The results showed that the majority of the salmon offspring experienced a thiamine deficiency-dependent mortality at different stages of larval development and that five family pairs experienced high mortality before hatch. In salmon, different kinds of disorders were also seen at hatch, such as vertebrae deformity, blood disorders, subcutaneous edema in the yolk sac, and precipitate in the yolk. The disorders at hatch were not correlated to later thiamine deficiency-dependent mortality. Aliquots of newly fertilized salmon eggs were injected with thiamine by the nanoinjection method. This treatment had only a minor effect on the frequency of disorders at hatch, but it protected the salmon larvae almost completely from later thiamine deficiency-dependent mortality. This indicates that factors other than thiamine deficiency are involved in the developmental disorders. In both salmon and cod from the Baltic Sea, the mortality and disorders among the offspring were mainly correlated to the female, and in both species some females produced offspring that experienced high mortality before hatch. Both salmon and cod also showed disorders that might have similar biochemical mechanisms, because the formation of precipitates and edema in the yolk sac occurs in both species.
