Estimating recreational fishing effort.
We use fixed-wing drones, visual surveys and anonymous data from personal echosounders to assess recreational fishing effort (see publication
). Our assessments show that from March 2020 until April 2021 about 110 thousand fishing trips occurred in Kaunas Water Reservoir (95% confidence range of 60-230 thousand). Currently we are continuing surveys in Kaunas WR to see how recreational fishing effort changed in 2021 and are expanding surveys to other areas in Lithuania. Estimation of angler catches.
Knowing the angler numbers is not enough, we also need to know how much they catch and how much they release. During 2020-2021 we conducted several hundred on-site angler surveys in Kaunas WR. Our data shows that annually anglers catch about 100 tons of fish (part of it is released) and the biggest impact is seen for perch, pikeperch and bream populations. These species show the slowest recovery since the ban of commercial fishing in 2013
, but they also do not show evidence of population decline. Promoting sustainable recreational fishing.
We contribute popular material to encourage responsible and sustainable recreational fisheries - illustrated fishing rules, short videos
, popular articles and more. We are also running a citizen science angler program that will contribute towards monitoring of fish population status.
