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).

Length correction for larval and early-juvenile Atlantic menhaden (Brevoortia tyrannus) after preservation in alcohol [PDF]
, 2005 Body length measurement is an important part of growth, condition, and mortality analyses of larval and juvenile fish. If the measurements are not accurate (i.e., do not reflect real fish length), results of subsequent analyses may be affected ...

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 ...

Performance of eDNA Filtration Methods for Monitoring Fish Diversity in a Hyper‐Tidal Estuary
Environmental DNA, Volume 7, Issue 5, September–October 2025.This study evaluates four eDNA filtering methods, three manual filters (0.45, 1.2, and 5 μm) and a passive method, the metaprobe, across a salinity gradient in a hyper‐tidal estuarine ecosystem. Results show that the 0.45 μm filter detected the highest species richness (39 species), followed by the metaprobe (35 species), and the 1.2 μm (34 species ...

Cryogenic and Refrigerated Storage of Rainbow Smelt Osmerus mordax Spermatozoa
Journal of the World Aquaculture Society, 2004 AbstractThe effects of extender composition, cryoprotectant, and freezing rate on post‐thaw rainbow smelt Osmerus mordax sperm motility were examined, and the fertilization capacity of fresh and post‐thaw sperm were compared. The highest post‐thaw motility (75%) was obtained when milt was diluted 1:3 with an extender containing 600 mM sucrose ...
