From spawner habitat selection to stock-recruitment: Implications for assessment. [PDF]

Ecol Evol, 2022
The relationship between the spawning stock size and subsequent number of recruits is a central concept in fisheries ecology. The influence of habitat selection of spawning individuals on the stock-recruitment relationship is poorly known.

Determination of the Reproductive Status of the Female Round Goby Neogobius melanostomus (Pallas, 1814) in Southwestern Lake Michigan [PDF]

Animals
The successful invasion of the round goby, Neogobius melanostomus (Pallas, 1814), in European and North American water ecosystems is assisted by its reproductive strategy, including high fecundity, multiple spawning events over an extended spawning ...

Genetic signs of multiple colonization events in Baltic ciscoes with radiation into sympatric spring‐ and autumn‐spawners confined to early postglacial arrival [PDF]

Ecology and Evolution, 2014
AbstractPresence of sympatric populations may reflect local diversification or secondary contact of already distinct forms. The Baltic cisco (Coregonus albula) normally spawns in late autumn, but in a few lakes in Northern Europe sympatric autumn and spring‐ or winter‐spawners have been described.

Comparison of known spawner abundance from fence counts to visual counts for simplified spawner estimation methods. [PDF]

, 2023
Many salmon species are monitored by visual counts of spawners in streams, however, there are few data sets where abundance is known and compared to estimates derived from visual counts. We used spawner fences to obtain known kokanee (Oncorhynchus nerka)
