“…The spawning in GG and VM populations occurs in summer, while in VM it appears to be a little later. A similar observation was made on Cerastoderma glaucum populations from the same sites (Tarnowska et al 2009) and on Macoma balthica and M. trossulus from the Gulf of Gdańsk (Pierścieniak et al 2010). The gonad index (GI) followed a similar pattern for both populations, with higher values in the reproduction period (springsummer; in the case of GG, the summer sample was collected already after breeding, thus the value of the gonad index was low) and lower values during the resting time (autumn and winter).…”

Seasonal variations of environmental factors, such as temperature and salinity, require metabolic acclimatization in sedentary benthic fauna distributed over a wide geographical range. The soft-shell clam Mya arenaria inhabits the coastal waters of the North Atlantic including North America and Europe. In Europe, M. arenaria populations are distributed from Iceland to the Mediterranean Sea, including the North Sea, the Baltic Sea and the Black Sea. Seasonal changes in physiological parameters (gonad index, condition index, biochemical composition and respiration rate) of M. arenaria from the Baltic Sea (the Gulf of Gdańsk, Poland), and the North Sea (Versee Meer, the Netherlands) were studied. The sex ratio of both populations did not differ from 1:1 and the seasonal gonad index was higher in the Baltic population. The average condition index changed seasonally at both studied sites, and was also higher in the Baltic population (except the autumn) compared to the North Sea. In * Corresponding author: ocemw@ug.edu.pl both studied populations, the content of proteins, lipids and carbohydrates in the soft tissue followed the seasonal variations, and it was higher in the Baltic population. The respiration rate was lower in the Baltic population, and seasonal changes in the respiration rate seem to be correlated with changes in the water temperature. Based on the results obtained in the present study, we suggest that Mya arenaria is characterized by a large phenotypic plasticity and differences in the observed physiological traits are due to acclimatization to ambient environmental conditions.

“…This could be caused by different health states of hosts. As evidenced by the results of the presented study, it is possible that conditions prevailing on the sandy bottom (less suitable for the Baltic clam) may negatively affect the health of clams (Pierścieniak et al 2010), which in turn may contribute to their infection (Pekkarinen 1984a). A larger number of infected Baltic clams come from station MW30.…”

Macoma balthica is a marine bivalve commonly occurring in the boreal zone. It is one of the most common zoobenthos species in the Baltic Sea, including the Gulf of Gdańsk, and a significant element of the food web. Observations of the infection prevalence in M. balthica from different parts of Gulf of Gdańsk were conducted in 2007-2008, taking into account the water depth. Metacercariae of Gymnophalloides (=Lacunovermis) macomae (prevalence: 89.0%) were found, as well as sporocysts with metacercariae of Parvatrema affinis (prevalence: 1.1%) and unidentified sporocysts with cercariae (prevalence: 1.3%). The most infected clams were found on the shallowest research station (30 m).

“…The feeding behaviour of M. trossulus as a suspension feeder depends on the presence of particulate matter, mainly phytoplankton, reaching its biomass peak during spring and summer. During autumn and winter, phytoplankton growth is limited or stopped due to the decreased temperature, limited availability of light and even surface ice cover (Pierścieniak et al 2010 ; Staniszewska et al 2015 ).…”

“…Such patterns could be linked to reduction or lack of food availability in colder seasons or to gonad development after spawning. Overlapping changes in metabolic rate result in winter hold up of absorbed food at the expense of reduction in vital processes (Pierścieniak et al 2010 ).…”

Mussels have the ability to control biomineral production and chemical composition, producing shells with a range of functions. In addition to biological control, the environment also seems to influence the process of biomineralization; thus, shells can be used as archives of ambient water parameters during the calcium carbonate deposition. Past and present environmental conditions are recorded in the shells in the form of various proxies including Mg/Ca or Sr/Ca ratios. For such proxies to be accurate and robust, the influence of biological effects including the size of studied organism must be examined and eliminated or minimized, so that the environmental signal can be efficiently extracted. This study considers mineralogy and elemental composition of shells representing four size classes of Mytilus trossulus from the Baltic Sea. Obtained results suggest that mineralogy and chemical composition change throughout the shell development due to most likely a combination of environmental and biological factors. The content of aragonite increases with increasing shell size, while the bulk concentrations of Na, Cd, Cu, U, V, Zn and Pb were found to decrease with increasing height of the shells. Therefore, using mussels for environmental monitoring requires analysis of individuals in the same size range.
