“…The streams are located mostly in the lowlands (200-600 m above sea level), are 2-8 m wide (the median value is 3 m), have mesotrophic or eutrophic nutrient levels, and have a fish biomass of 150-300 kg per hectare. They are dominated by brown trout Salmo trutta and gudgeon Gobio gobio [11].…”

“…In total, 170,000 fish weighing 87 tons were harvested in the streams of the Bohemian region in the year 2020 [12]. This number is declining every year and fell by 10% over the years 2000-2018 [11]. Anglers mostly harvested salmonids, mainly rainbow trout Oncorhynchus mykiss (70% by biomass), brown trout Salmo trutta (10%), and European grayling Thymallus thymallus (2%).…”

The brown trout Salmo trutta is a fish species that is vulnerable to climate change and anthropogenic activities in its native range. The case studies of successful restoration of brown trout populations are rare. In this study, fishery managers who successfully restored brown trout populations are sharing their know-how and advice about their conservation strategy. Overall, twenty fishery managers were interviewed to give advice about their successful conservation practices of local brown trout populations. Using a qualitative analysis method, ten main recommendations were extracted: (1) assess the status of local brown trout populations, (2) form a union of fisheries managers and work together, (3) support the ability of the streams to retain water, (4) prevent artificial removal of water from the salmonid streams, (5) adjust the brown trout stocking strategy to individual streams, (6) set strict protection of native wild brown trout populations, (7) enforce angling bans and regulations, (8) support the rearing of brown trout in the aquaculture sector, (9) limit brown trout stocking to genetically native fish, and (10) stock smaller 0 + brown trout instead of large adult ones. In conclusion, the fishery managers agreed on the basic management steps that need to be made to conserve brown trout populations.

Inland recreational fisheries, found in lakes, rivers, and other landlocked waters, are important to livelihoods, nutrition, leisure, and other societal ecosystem services worldwide. Although recreationally-caught fish are frequently harvested and consumed by fishers, their contribution to food and nutrition has not been adequately quantified due to lack of data, poor monitoring, and under-reporting, especially in developing countries. Beyond limited global harvest estimates, few have explored species-specific harvest patterns, although this variability has implications for fisheries management and food security. Given the continued growth of the recreational fishery sector, understanding inland recreational fish harvest and consumption rates represents a critical knowledge gap. Based on a comprehensive literature search and expert knowledge review, we quantified multiple aspects of global inland recreational fisheries for 81 countries spanning ~192 species. For each country, we assembled recreational fishing participation rate and estimated species-specific harvest and consumption rate. This dataset provides a foundation for future assessments, including understanding nutritional and economic contributions of inland recreational fisheries.
