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 ...

Variation in Ovary Size of Osmerus mordax (Mitchell), the Rainbow Smelt, in Lakes Erie and Ontario
, 1991 Addressing three problems with respect to the reproductive effort of rainbow smelt, Osmerus mordax (mitchell), this study determines whether or not there is a significant inter-population difference in the gonadosomatic index or reproductive effort ...
