Abstract Marine recreational fishing ( MRF ) is a high‐participation activity with large economic value and social benefits globally, it impacts on some fish stocks. Although reporting catches European Union legislative requirement, estimates are only available for countries. Here, data numbers of fishers, participation rates, days fished, expenditures, two widely targeted species were synthesized to provide placed in the global context. Uncertainty assessment was not possible due incomplete...
The northern pike (Esox lucius) is an iconic predatory fish species of significant recreational value and ecological role in the Baltic Sea. Some earlier studies indicate local declines region, but a thorough spatial evaluation regional population trends Sea lacking. In this study, we collate data from 59 unique time-series fisheries landings fishery-independent monitoring programs to address temporal populations since mid-2000′s eight countries surrounding common analysis considering all...
This work is the result of an international research effort to determine main impacts COVID-19 pandemic on marine recreational fishing. Changes were assessed (1) access fishing, derived from lockdowns and other mobility restrictions; (2) ecosystems, because alterations in fishing intensity human presence; (3) blue economy, investments expenses fishers; (4) society, relation variations fishers’ health well-being. For this, a consultation with experts 16 countries was carried out, as well...
Abstract Smartphone applications (apps) that target recreational fishers are growing in abundance. These apps have the potential to provide data useful for management of fisheries. We surveyed expert opinion 20, mostly European, countries assess current and future status app use marine The survey revealed a few already support existing collection, this number is likely increase within 5–10 years. strongest barriers were scarcity concern over quality, especially biases due opt-in nature use....
The chromosomal characteristics, locations and variations of the C-band positive heterochromatin telomeric DNA sequences were studied in European grayling karyotype (Thymallus thymallus, Salmonidae) using conventional C-banding, endonucleases digestion banding, silver nitrate (AgNO3), chromomycin A3 4′,6-diamidino-2-phenylindole staining techniques as well fluorescence situ hybridization (FISH) primed labelling. Original data on distribution segments resistant to AluI restriction...
Abstract Human impact does not only affect the abundances of fish, but also age- and size-distributions. Indicators fish age size-structures can hence be useful tools for fisheries- environmental management. Size-based indicators have been tested proposed large, homogenous marine ecosystems with high fishing mortality, rarely fine-scaled heterogeneous in coastal zones. Here we analyse a suite size communities Baltic Sea, including mean median length, 10th 90th-percentile length distribution...

Abstract Anisakidae nematodes, especially Contracaecum osculatum , Anisakis simplex and Pseudoterranova decipiens, have dispersed throughout the Baltic Sea over last decade. Despite fact that salmon, Salmo salar is a popular choice among consumers therefore one of most valuable fish species, information about level infection salmon liver with these zoonotic nematodes sparse. In 2020, total 120 livers were inspected for presence parasites showing 13% infected C. . Furthermore, single sp....
Fluctuating asymmetry (FA), an indicator of developmental instability, has been suggested to serve as a useful bioindicator the fitness and condition various groups animals, including fish. The current study aimed determine whether skeletal body deformities northern pike fry (3–12 cm standard length SL) reared under laboratory conditions imposed stress that was reflected in FA otolith size (area). Although hatchery-reared fish were studied, also occurs natural may indicate harmful effects...
Abstract Each year, millions of hatchery‐reared sea‐run brown trout Salmo trutta L. (the sea trout) juveniles are released into the natural environment in Atlantic region. The aim this work was to investigate growth responses changing temperature conditions and compare plasticity between wild fish. Scales were collected from a selected river flowing southern Baltic Sea. We analyzed scale increment widths as proxy somatic investigated interannual variabilities differences fish groups (wild...
Abstract Stocking can affect population density but may influence fish growth responses to changes in environmental conditions. In a multi‐year field experiment, we investigated the interactive effects of and temperature on young‐of‐the‐year anadromous brown trout streams stocked with wild‐origin hatchery‐reared trout. Fish origin was predominant factor influencing rate, thereby highlighting importance discriminating between wild individuals. Growth positively related (degree‐days)...
Low Temperature Effect on Multiple Alizarin ImmersionMass-Marking of Juvenile Sea Trout Salmo trutta m. L. otoliths (Caudron & Champigneulle
Abstract The poor results of lake-migratory brown trout, Salmo trutta lacustris L., restoration in Lake Hańcza Nature Reserve prompted undertaking the current study that sought to verify if hatchery-reared fish age 2+ can survive critical period acclimation and remain lake. Thirty-one individuals were tagged with coded acoustic transmitters observed for 317 days. This method helped analyze: 1) spatial behavior one year following their release; 2) possible differences released various places...
