TL;DR: The present study aims at disentangling the interactions between reproductive effort and hydrographic forcing leading to variable recruitment in the eastern Baltic cod stock using updated environmental and life stage-specific abundance and production time-series.

TL;DR: A review of the abundance of recent research on skipped spawning in fishes, covering a broad range of fishes with diverse life history strategies, and attempting to advance current knowledge by providing the first review discussion of skippedSpawning in males.

TL;DR: This special section of Marine and Coastal Fisheries contains contributions from a workshop on the gonadal histology of fishes that was held in Cadiz, Spain, during June 2009, and suggests needs for future research and integration of reproductive data into both conceptual and quantitative models to better understand how reproductive performance affects population dynamics.

TL;DR: Environmental factors showing statistically significant covariance with the survival of one of these critical life stages were incorporated into stock-recruitment models for individual spawning areas separately and for the Central Baltic combined.

TL;DR: In this review, nine stocks illustrate the range of approaches that are being taken to developing alternative indices of reproductive potential from existing data resources and showed the relationship between SSB and TEP to be variable and characterized by distinct time trends.
