How fishing regulations, free time, seasonality and angler characteristics shape daily fishing pressure and angling success: Insights from Czech recreational fisheries

Popis výsledku v původním jazyce

Recreational fishing is a widespread leisure activity and an important source of fish mortality. Angler behaviour affects fishing pressure, but the causes of seasonal patterns of fishing pressure and success remain poorly understood. We used data from > 565,000 individual daily fishing trips in the three largest fishing areas in Czechia during three years to decipher the seasonal patterns of fishing pressure and success, including possible differences between angler groups defined by their proximity to the fishing area (‘local’, ‘regional’ and ‘distant’) and by the target fish based on their annual catches (anglers reporting no catches and those focussing on carp or predatory fish and generalists). We found that total fishing pressure was predictably seasonal in each area, showing a broadly unimodal pattern that peaked around week 30 and increased during weeks with short public holidays. Fishing pressure of the different angler groups responded differently to the open fishing season for predatory fish (16 June to 31 December each year), with the strongest positive effect found among anglers who focussed on predatory fish or who reported no catches from the three areas. Daily fishing success fluctuated throughout the season and varied greatly between anglers. Individual success declined with daily fishing pressure and increased with the angler’s total effort when anglers reporting no catches were included in the analysis. We also detected area- and year-specific differences in the individual success of both distance-based and catch-based angler groups, as well as area- and year-specific effects of the open fishing season for predatory fish on the individual success of catch-based angler groups. While seasonal patterns of fishing pressure were similar across years in each fishing area, our analysis identified area-specific patterns of short-term fishing pressure and individual success that could indicate shifts in angler preferences or possible overfishing. Overall, we show that external factors such as fishing regulations and public holidays directly influence the seasonality of fishing pressure and indirectly modulate the success of individual anglers. Our approach may pave the way for more detailed analyses of fine-scale temporal dynamics in recreational fisheries.
