Journal of Fish Biology, EarlyView.Abstract Atlantic herring Clupea harengus are total spawners that exhibit a large degree of reproductive plasticity and have substantial intra‐annual variation in their energetic condition. Recent research suggests that the species may be declining in energetic condition in the northwest Atlantic Ocean from the few historical records, but comparisons ...

Journal of Fish Biology, EarlyView.Abstract Broodstock management in aquaculture aims to optimise larval production to meet farm demand, which requires precise monitoring of the reproductive cycle. Traditional methods such as histology often require killing of fish, making them unsuitable for monitoring reproductive dynamics at fish level.
