Abstract For the first time an international acoustic survey dataset covering three decades was used to investigate factors shaping spatial and temporal patterns in condition of sprat herring Baltic Proper. Generalized additive models showed that fluctuations density have been main drivers spatio‐temporal changes both condition, evidencing intra‐ inter‐specific dependence mediated by size distribution population. Salinity also important predictor whereas temperature explained only a minor...
Abstract Otolith microstructure analysis and hydrodynamic modelling were combined to study growth patterns in young‐of‐the‐year (YoY) sprat, Sprattus sprattus , which sampled October 2002 the central Baltic Sea. The observed ‘window of survival’, approximated by distribution back‐calculated days first feeding (DFF), was narrow compared extended spawning season sprat Sea (mean± SD = 22 June ± 14.1 days) indicated that only individuals born summer survived until 2002. Within group survivors,...
Abstract Native to the Ponto-Caspian region, benthic round goby ( Neogobius melanostomus ) has invaded several European inland waterbodies as well North American Great Lakes and Baltic Sea. The species is capable of reaching very high densities in ecosystems, with not only evidence for significant food-web effects on native biota habitats, but also negative implications coastal fishers. Although generally considered a species, it been shown that migrate deeper areas other lakes during cold...
Spatio-temporal density-dependent processes are crucial regulatory factors for natural populations. However, there is a lack of studies addressing spatial density-dependence in fish growth. A previous investigation has suggested spatio-temporal body condition Baltic sprat. Here, we used different techniques, such as centre gravity, distance, and homogeneity indices, to better characterize the temporal variations sprat density Proper. Our results evidenced negative co-variation between...
Abstract Cod is usually monitored for scientific purposes using bottom trawl surveys, although its regular pelagic occurrence well documented. Here we analysed, Generalized Additive Models, the spatio-temporal changes in Eastern Baltic cod adult population catches from an acoustic survey covering 37 years and whole central Sea. Our analysis shows that northern areas catch per unit effort (CPUE, kg h-1) was high early 1980s whereas it dropped remained very low thereafter. Conversely,...
Baltic cod, like other species, is susceptible to inter-annual fluctuations in sexual maturation, depending on the length, age, sex, extent of habitat area, and stock abundance cod population. Maturity one biological indicators used detect changes a that can be caused by fishing. To address these issues specifically for eastern stock, long-term data (1990–2006) from Polish research vessels southern were examined. date, ICES has same maturity ogives over extended periods assumed invariant sex...
During the BMB/ICES Workshop on “Fish Diseases and Parasites in Baltic Sea”, 25 November to 8 December 1994, samples of herring Clupea harengus sprat Sprattus sprattus taken along a transect from southwestern northeastern Sea were examined externally for presence symptoms diseases emaciation, internally infestation with Anisakis simplex. The results indicate significant geographical differences prevalence all three herring, but interpretation is complicated by apparent size dependence. This...
