Parasites as Biological Tags
Ken MacKenzie,Pablo Abaunza +1 more
TL;DR: This chapter provides a guide for parasitologists and fishery biologists to the use of parasites as biological tags for stock identification of marine fish, and recommends an interdisciplinary approach in which the results from different methods are compared and used to complement one another.

Evidence for metapopulation structuring in cod from the west of Scotland and North Sea
TL;DR: The scale of population structuring in cod Gadus morhua from the west of Scotland and northern North Sea was investigated using a combination of non-genetic methods, indicating that most adults originate from local nursery areas and spawning aggregations functioning as local populations within a metapopulation.

Temporal and geographic variability of sardine maturity at length in the northeastern Atlantic and the western Mediterranean
Alexandra Silva,M. B. Santos,B. Caneco,G. Pestana,C. Porteiro,Pablo Carrera,Yorgos Stratoudakis +6 more
TL;DR: Associated increases in fish condition and fat reserves during the summer feeding season suggest that variations in reproductive traits may have been caused by environmentally driven changes in food availability.
Journal ArticleDOI
The importance of comparative studies in stock analysis
TL;DR: The identification and discrimination of stocks of fishes lies at the interesting juncture of fishery biology and fish microevolution and would benefit from a greater understanding of the trajectories of differentiation of analyzable features-gained from comparison between approaches from amicroevolutionary point of view.
Journal ArticleDOI
Reconciling stock assessment and management scales under conditions of spatially varying catch histories
TL;DR: In this paper, a quantitative evaluation of spatial stock structure assumptions on the performance of stock assessments relative to management scales is presented, where catch histories, not biological differences, are used to create stock structure.

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...
