A Two Discrete Stock Hypothesis for South African Sardine Resource [PDF]

, 2016
The two discrete stock hypothesis for South African sardine has been extended. An improved fit to the data has been obtained. These results show that the hypothesis of two discrete stocks of sardine in South African waters can fit the observed data well.

Selection of acceptable levels of risk for South African small pelagics: the probability of dropping below pre-defined risk thresholds [PDF]

, 2021
This document considers alternative methods to define acceptable risk levels – or acceptable probabilities of dropping below limit-like reference or “risk” thresholds - for use in tuning Candidate Management Procedures for the South African sardine and ...

Patterns of Population Genomic Variation and Evolutionary History of European Hake in the Northeastern Atlantic

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We use for the first time whole‐genome sequencing to explore current and historical patterns of genetic diversity in European hake in the Northeastern Atlantic, focusing on the recently expanded distribution range in the North Sea. Genomic data revealed a complex scenario with three populations: North Sea, Celtic Sea and Portugal.

Facilitative interspecific interactions in marine vertebrates across scales: from individuals to ecosystems

Biological Reviews, Volume 101, Issue 1, Page 519-538, February 2026.
ABSTRACT Facilitative interspecific interactions (FIIs) confer benefits to at least one participant without detriment to others. Although often less emphasised than antagonistic interactions in ecological studies, this review highlights the significant ecological role of FIIs across biological scales – from individual behaviours to population ...

ANEMONE Global's First eDNA‐Based Assessment: Insights Toward a Standardized Global Monitoring Network

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Using a standardized eDNA metabarcoding workflow across 12 countries, ANEMONE Global reveals large‐scale patterns in coastal fish biodiversity shaped by habitat complexity, ocean basin, and diel variation. The study demonstrates the feasibility of globally coordinated, high‐resolution marine biodiversity monitoring using eDNA.

Assessment of the South African sardine resource using data from 1984-2011: initial results for a two stock hypothesis [PDF]

, 2016
As part of the process of updating the assessment of the South African sardine resource, a sardine two mixing-stock hypothesis is to be tested. This hypothesis postulates a “west” stock distributed west of Cape Agulhas and a “south” stock distributed ...

Investigating Environmental DNA Variability and Species Detections Through Passive and Active Sampling Across Time: A Case Study From a Hyper‐Diverse Coastal System

Environmental DNA, Volume 8, Issue 1, January–February 2026.
This study compared the ability of active and passive eDNA filtration methods to capture environmental DNA in a marine environment with highly variable eDNA signals. Active sampling detected a greater proportion of fish biodiversity, whereas passive sampling detected a larger proportion of metazoa, with a trend of significant accumulation of numbers of

Foraging ecology of the African Penguin Spheniscus demersus in relation to ocean physical processes. [PDF]

, 2012
Includes abstract.This research demonstrated the dual utility of bio-loggers as a method for generating accurate, high-resolution oceanographic data. These data can be used in future studies, generating a cross disciplinary platform for research.

Nutrient Composition of Marine Fish Species From the East African Coast: Implications for Food and Nutrition Security

Food Science &Nutrition, Volume 14, Issue 1, January 2026.
This study novel analytical data of 24 commonly consumed marine fish species from East Africa to assess their nutrient content and contribution to Codex nutrient reference values. Results showed that small fish species, typically eaten whole, are richer in key micronutrients compared to larger, filleted species. These findings highlight the nutritional

Assessing the South African sardine resource: two stocks rather than one? [PDF]

, 2016
Sardine Sardinops sagax distributed off the west and south coasts of South Africa have traditionally been assumed to comprise a single well-mixed stock for assessment and management purposes.
