How to know about waters? Finnish traditional knowledge related to waters and implications for management reforms

“…Today the Finnish governance of waters relies primarily on expert and scientific knowledge (Bilaletdin et al 2010;Hölli 2010;Salmi 2000;Söderholm et al 2018;Vehanen et al 2020). Traditional knowledge was belittled (Saiha and Virkkunen 1986) for a long time and created a low self-esteem among the fishermen.…”

“…Modern society approaches weather prediction and ecosystem monitoring using scientific and modelling parameters (for example in Rontu et al 2019). Decision-making at the science-policy interface relies on expert knowledge (Salmi 2000;Vehanen 2020) that informs a range of governance levels from the international treaties regarding waters into the European Union to national and ultimately the municipality and community levels.…”

“…In Finland the recent decades have seen the rise of an orderly discussion and debate between 'user' and citizen science (Gabrys et al 2016;Turbé et al 2019) and expert-driven scientific assessments regarding waters (Salmi 2000(Salmi , 2013Vehanen et al 2020). With the advent of smart phones and sophisticated sonar, camera and GPS technologies local people have shared observations of fish catches, water quality, diatomic algae bloom events and many other day-today information pieces regarding lakes and rivers.…”

Quality indicators of fish from the water of the southern region of Ukraine

“…); 4) atmospheric pollution and acid rain. All these factors have a negative impact on the ecological situation of the Khadzhibey estuary (Gupta & Singh, 2019;Tien et al, 2020;Vehanen et al, 2020;Sayed-Lafi & Al-Budairy, 2023).…”

A history of Greek inland fishery development during 1928–2019

“…Even though inland fisheries are one of the oldest activities (Sahrhage & Lundbeck, 1992), accurate data on commercial inland fisheries are limited for many countries worldwide (Cowx, 2015;Funge-Smith, 2018;Vehanen et al, 2020). In addition, relatively a few historical inland fisheries have been studied quantitatively (e.g., Schubert et al, 2021).…”
