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.

TL;DR: A counter-intuitive finding of this review is that, although the DEPM is almost exclusively applied to clupeoids, recent evidence indicates that it may be easier and cheaper to use in other teleost families, including demersal species.

TL;DR: Samples of Atlantic sardine Sardina pilchardus were collected bimonthly from 2004 to 2008 to describe the reproductive activity of this indeterminate batch-spawning species; compare the seasonality of somatic growth, condition, and feeding; and evaluate differences between sexes.

TL;DR: The pattern of oocyte development was investigated in the Mediterranean sardine in order to examine whether non-hydrated females could be included in batch fecundity measurements and it was found that group-synchronous type of oocytes development is exhibited in this species.

TL;DR: Despite differences in temperature and productivity regimes, reproductive performance of sardine in the Ionian Sea was very similar to that in the Aegean Sea during the peak of the spawning period, implying that mean relative batch fecundity of sARDine is fairly constant in contrasting ecosystems around the world.
