TLDR
In this paper, the authors review different approaches used in identifying and classifying stocks and advocate that an holistic approach (e.g., involving a broad spectrum of complementary techniques) be used in future stock identification studies.About:

Morphometric variation among sardine (Sardina pilchardus) populations from the northeastern Atlantic and the western Mediterranean
TL;DR: Principal components analysis on size-corrected truss variables and cluster analysis of mean fish shape using landmark data indicate that the shape of sardine off southern Iberia and Morocco is distinct from the shape in the rest of the area, casting doubts on the hypothesis that the stock is a panmictic, closed population.
Journal ArticleDOI
Genetic identification of Anisakis larvae in European hake from Atlantic and Mediterranean waters for stock recognition
TL;DR: There were significant differences in the relative proportions of the various Anisakis species identified in hake samples from the Mediterranean Sea and Atlantic Ocean, suggesting the existence of different stocks of M. merluccius in European waters.

TL;DR: The discovery of hidden diversity within a large, critically endangered marine vertebrate demonstrates how marine biodiversity can be underestimated, even in such a relatively well-studied and heavily exploited region.
Journal ArticleDOI
Otolith shape analysis as a tool for stock separation of horse mackerel (Trachurus trachurus) in the Northeast Atlantic and Mediterranean
TL;DR: The results of this study indicate that the separation line between the western and the southern stock should be shifted to the coast of southern Galicia (Cape Finisterre), and the stock-adaptive assessment and sustainable management of horse mackerel in the Northeast Atlantic and Mediterranean will be significantly improved.
Journal ArticleDOI
Combined methods of otolith shape analysis improve identification of spawning areas of Atlantic cod
TL;DR: Investigation of the effectiveness of otolith shape for identifying Atlantic cod spawning populations in the northern North Sea and west coast of Scotland indicated that spawning groups from Viking Bank and Moray Firth had different shapes from those of cod in other spawning areas.

Stock Identification: Materials and Methods
TL;DR: Various population parameters and physiological, behavioral, morphometric, meristic, calcareous, biochemical, and cytogenetic characters have been used to identify fish stocks and each character set and the associated methodology relates to specific aspects of the stock definition.

Stock Discrimination Using Otolith Shape Analysis
TL;DR: There were highly significant differences in otolith shape among most of the cod samples, but shape also differed among ages, sexes, and year-classes, indicating that growth rate contributes more variation to regional differen...
