TLDR
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.Abstract:
The traditional view of iteroparity in fishes is one of an annual reproductive cycle that culminates each year in spawning. More recently, a more flexible view of fish reproduction has been adopted, including the potential for mature fish to skip spawning. Here, we review the abundance of recent research on skipped spawning, covering a broad range of fishes with diverse life history strategies. Evidence for skipped spawning has been collected by use of traditional histological techniques as well as modern technological advances, such as satellite tags and the ability to track fish movements based on elemental and isotope signatures. Skipped spawning is most commonly attributed to deficient diet and poor nutritional condition. Advances made in this field of study in recent years include descriptions of hormonal changes that precede and perhaps initiate skipped spawning, the development of life history models that incorporate the potential for skipped spawning, and estimates of the degree to which ...read more

A Standardized Terminology for Describing Reproductive Development in Fishes
Nancy J. Brown-Peterson,David M. Wyanski,Fran Saborido-Rey,Beverly J. Macewicz,Susan K. Lowerre-Barbieri +4 more
TL;DR: This work proposes the adoption of a simple, universal terminology for the phases in the reproductive cycle, which can be applied to all male and female elasmobranch and teleost fishes, and includes immature, developing, spawning capable, regressing, and regenerating.

Energy acquisition and allocation to egg production in relation to fish reproductive strategies
Richard S. McBride,Stylianos Somarakis,Gary R. Fitzhugh,Anu Albert,Nathalia A Yaragina,Mark J. Wuenschel,Alexandre Alonso-Fernández,Gualtiero Basilone +7 more
TL;DR: For example, the authors found that many species exhibit mixed capital-and income-breeding patterns, and that poor-feeding environments can lead to delayed maturation, skipped spawning, fewer spawning events per season or fewer eggs produced per event.

Reproductive Timing in Marine Fishes: Variability, Temporal Scales, and Methods
Susan K. Lowerre-Barbieri,Konstantinos Ganias,Fran Saborido-Rey,Hilario Murua,John R. Hunter +4 more
TL;DR: The temporal aspects of reproductive strategies and the four most-studied reproductive timing characteristics in fishes are reviewed, which synthesize how it has traditionally been measured, advances in understanding the underlying physiology, its role in equilibriumbased fish population dynamics, and its importance to reproductive success.

Emerging Issues and Methodological Advances in Fisheries Reproductive Biology

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.

Frequent skipped spawning in the world’s largest cod population

TL;DR: It is proposed that skipped spawning is an integral life-history component for NEAC, likely varying annually, and it could therefore be an underlying factor causing some of the currently unexplained large NEAC recruitment variation.

TL;DR: Teleosts offer examples of virtually every conceivable type of ovarian physiology and provide a wealth of experimental material for exploring the cellular and hormonal mechanisms which regulate oocyte recruitment and growth throughout ovarian recrudescence.

TL;DR: The results are consistent with two populations of bluefin tuna with distinct spawning areas that overlap on North Atlantic foraging grounds, and Restrictions on the time and area where longlining occurs would reduce incidental catch mortalities on western spawning grounds.

Reproductive strategies of Atlantic salmon: ecology and evolution
TL;DR: While knowledge about the breeding of Atlantic salmon is detailed, it is only beginning to understand the ultimate causes and/or functional significances of their reproductive strategies, and predictive models of the life history variation are developing, focusing on the need for empirical study and testing of life history and reproductive patterns.
