Successful stocking of wild European perch in a reestablished lake with lasting effect over 10 years
Restoration Ecology, Volume 34, Issue 1, January 2026.Biological manipulation of fish compositions to enhance top‐down control of trophic webs is a common method for improving water and ecological quality in shallow eutrophic lakes, but it often fails. As an alternative to manually thinning unfavored fish stocks, piscivorous fish species can be released to suppress the recruitment of cyprinid fish ...

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.ABSTRACT Climate change is altering north‐temperate lake ecosystems through warming and increased aquatic macrophyte production. These changes have the potential to cause ecosystem shifts that challenge status quo fisheries management and require the adoption of new strategies to resist, accept, or direct such shifts.

Growth of different year classes of smelt Osmerus eperlanus L. in Lake Tyrifjorden, Norway
Fauna Norvegica, 1982 Smelt Osmerus eperlanus L. were collected during spawning run in May in Lake Tyrifjorden in southern Norway. Age determination was carried out by otoliths. Fish length (Y) and otolith radius (X) were correlated (r = 0.954).

Larval Entrainment Through Fort Randall and GAVINS Point Dams, Lewis and Clark Lake, South Dakota
River Research and Applications, Volume 41, Issue 10, Page 2205-2217, December 2025.ABSTRACT Entrainment of Walleye Sander vitreus and Sauger Sander canadensis has been documented in all the Missouri River reservoirs in South Dakota and is a hypothesized mechanism through which source‐sink dynamics occur. However, an assessment of larval entrainment through Fort Randall Dam and Gavins Point Dam, which bound Lewis and Clark Lake, has ...
