“…The lagoon's average water exchange time is only 55 days, and a salinity of around 1.5 psu shows that the lagoon is only to a minor degree influenced by the Baltic Sea, which has a salinity of 6 psu (Radziejewska and Schernewski 2008). Because of the lagoon's low salinity, zebra mussels (Dreissena polymorpha) are the only filter-feeding epifaunal bivalves in the lagoon; they form mussel beds with a biomass of about 68,000 t (Piesik et al 1998, Wozniczka and Wolnomiejski 2008, Radziejewska et al 2009). Zebra mussels were introduced into the Oder Lagoon in the nineteenth century (Gruszka 1999), but their prevalence throughout northern Germany even before the last ice age are the reason for considering zebra mussels to be native species (Fenske 2003, Stybel et al 2009).…”

“…The mussels feed on detritus, phytoplankton, and zooplankton. However, in this analysis we use an empirical relationship between zebra mussel biomass and water transparency in the Oder Lagoon, which we derived from data in Wolnomiejski and Wozniczka (2008). Zebra mussels in the amount of 0.1 kg/m³ of lagoon water improve water transparency (Secchi depth) during the summer season by 0.39 m. Water transparency serves as the major link between ecology and economy (Fig.…”

ABSTRACT. The Oder (Szczecin) Lagoon in the southern Baltic Sea is a heavily eutrophicated and degraded coastal ecosystem. We applied a systems approach framework to critically evaluate whether existing water-management measures achieve waterquality objectives for the river and lagoon systems. Our simulations reveal that the existing water-quality objectives for the river and the coastal waters are not sufficiently complementary. We suggest new water-quality threshold concentrations, which are in agreement with the European Water Framework Directive, and we calculate acceptable maximum nutrient loads for the Oder River. These calculations suggest that external nutrient-load reductions in the river basin alone seem insufficient to achieve good water quality in the lagoon. A comprehensive eutrophication management approach should also include internal nutrientretention and nutrient-removal measures in the lagoon. We focus on mussel farming, i.e., that of zebra mussels, Dreissena polymorpha, because they are efficient in removing nutrients and improving water transparency in the Oder Lagoon. For this purpose, the ecosystem model ERGOM is extended by a mussel module and an economic model. The economic model describes costs and benefits of mussel cultivation depending on the the farm size. We included additional potential sources of income such as water-quality tax or emission certificates. The simulations show that mussel farming in the lagoon is a suitable supportive measure and, at a load-reduction target of 50% or more, it is a cost-efficient measure for removing nutrients and for implementing the Baltic Sea Action Plan. In the Oder Lagoon, mussel farming could potentially remove nearly 1000 t of N (70 t of P)/year, or about 2% of the present N and P loads, and it would have the additional benefit of improving water transparency.

“…Zaiko et al (2014), like Strayer and Malcom (2006), stressed the importance of long-term observations for an appropriate assessment of invader population fluctuations. Following this line of reasoning and referring to older data (Wiktor, 1962(Wiktor, , 1969Piesik, 1992;Masłowski, 1993;Woźniczka and Wolnomiejski, 2005;Wolnomiejski and Woźniczka, 2008), it may be assumed that D. polymorpha had reached the accommodation phase in the Lagoon prior to the appearance of D. rostriformis bugensis. It is likely that immigration of the quagga has perturbed the zebra mussel accommodation, as abundance fluctuations as well as certain demographic traits (Wawrzyniak-Wydrowska et al, in prep.…”

“…m −2 . And yet, the 2005 survey (Wolnomiejski and Woźniczka, 2008) revealed a distinct (even fourfold) decline in the Lagoon's zebra mussel population. The authors quoted ascribed the decline to the habitat's trophic capacity being exceeded due to excessive growth of the population in the preceding years, which resulted in the food resources being depleted by intensive filtration of the large population.…”

Two Non-indigenous Dreissenids (Dreissena polymorpha and D. rostriformis bugensis) in a Southern Baltic Coastal Lagoon: Variability in Populations of the “Old” and a “New” Immigrant

Dreissena polymorpha and D. rostriformis bugensis are freshwater Ponto-Caspian bivalve species, at present widely distributed in Europe and North America. In the Szczecin Lagoon (a southern Baltic coastal lagoon), the quagga was recorded for the first time in 2014 and found to co-occur with the zebra mussel, a long-time resident of the Lagoon. As the two species are suspected of being competitors where they co-occur, their population dynamics was followed at a site the new immigrant was discovered (station ZS6, northern part of the Lagoon) by collecting monthly samples in 2015-2017. The abundance and biomass of the two congeners showed wide fluctuations, significant differences being recorded between months within a year and between years. The abundance and biomass proportions between the two congeners changed from an initial domination of the newcomer quagga until mid-2015 to a persistent domination of the zebra mussel throughout the remainder of the study period. Both the abundance and biomass of the two dreissenids showed a number of significant associations with environmental variables, notably with salinity, chlorophyll a content, and temperature. The co-occurrence of the two dreissenids in the Lagoon is discussed in the context of their invasion stage; it is concluded that while the quagga seems to have achieved the "outbreak" stage, the zebra mussel, an "accommodated" invader present prior to the quagga immigration, reverted to that stage.

“…In fall and winter, both species feed primarily on zoobenthic invertebrates, including mollusks such as the zebra mussel Dreissena polymorpha (del Hoyo et al 1992 ; De Leeuw et al 1999 ). This mollusk is very common in the Szczecin Lagoon, although in recent years, there has been a drastic reduction in the abundance of this species in some parts of this water body (Wolnomiejski and Wozniczka 2008 ; Radziejewska et al 2009 ). It is worth noting that the zebra mussel is very resistant to F − in water, and its concentration reaches a higher values in soft tissues than in the calcium carbonate-rich shells, which has been experimentally shown by Del Piero et al ( 2012 ).…”

The aim of the study was to investigate fluoride concentrations in bone, brain and pineal gland of goosander Mergus merganser wintering in the Odra estuary (Poland) as well as in fish originating from its digestive tract. The fluoride concentrations were determined with potentiometric method. Medians of concentrations in goosander had the highest and the lowest values in pineal gland and brain ([760 and \190 mg/kg, respectively). Fluoride concentration in the pineal gland was significantly greater than in the bone and the brain of the duck. In fish, the fluoride concentration ranged from 37 to 640 mg/kg and significant correlation was revealed between the fluoride concentration and fish weight and length. Based on own results and data of other authors, a daily fluoride intake by the goosander in the Odra estuary was estimated at 15 mg. So high fluoride concentrations like in the duck have not been found in mammal brains.
