Inland fisheries are the main source of socioeconomic and food security for millions of families living in riverside communities around the world (Welcomme et al.2010; Alves and Minte-Vera 2013; Youn et al.2014; Gurung 2016; Lynch et al.2017). These fisheries involve small ponds and reservoirs, as well as major rivers (Beard et al.2016). It is not surprising that local fisheries involve the capture of a great variety of fish species (Lopes et al.2019). In 2016, inland fisheries’ global production reached 11.6 million tonnes, about 13% of all marine and inland catches (FAO 2018). However, this number is likely underestimated because it does not include catches intended for domestic consumption (Hallwass et al.2011; Lopes et al.2019).

Human population growth, economic crises, and local vulnerabilities threaten inland fisheries stock, especially where there is direct exploitation of water resources by other dependent sectors (e.g., hydroelectric power) (Baran and Myschowoda 2009...
