IOBSERVER: species recognition via computer vision [PDF]

, 2016
This paper is about the design of an automated computer vision system that is able to recognize the species of fish individuals that are classified into a fishing vessel and produces a report file with that information. This system is called iObserver

No more time to stay ‘single’ in the detection of Anisakis pegreffii, A. simplex (s. s.) and hybridization events between them: a multi-marker nuclear genotyping approach [PDF]

, 2016
A multi-marker nuclear genotyping approach was performed on larval and adult specimens of Anisakis spp. (N = 689) collected from fish and cetaceans in allopatric and sympatric areas of the two species Anisakis pegreffii and Anisakis simplex (s.

Viral Nervous Necrosis due to Betanodavirus: A Case Study in Pot‐Bellied Seahorses (Hippocampus abdominals)

Journal of Fish Diseases, Volume 48, Issue 10, October 2025.
ABSTRACT Betanodaviruses, members of the Nodaviridae family, are the causative agents of viral nervous necrosis in fish, resulting in great economic losses worldwide. This is the first case study describing the detection and confirmation of viral nervous necrosis in pot‐bellied seahorses (Hippocampus abdominalis) in Australia.

Preliminary data on Trachurus picturatus (Bowdich 1825) phylogeography inferred from mitochondrial DNA sequence data

Frontiers in Marine Science, 2015
The populations of marine pelagic fishes, in particular the migratory ones as the Trachurus picturatus (Bowdich 1825), may be erroneously considered an homogenous population unit because they show broad geographic distributions, large population sizes ...

Recurrence of the Spatial Structure of Summer Larval Fish Assemblages Linked to Hydrodynamics in the NW Mediterranean

Fisheries Oceanography, Volume 34, Issue 5, Page 99-120, September 2025.
ABSTRACT In this study, we aim to investigate the contribution of various sources of variability, environmental, spatial and interannual on the larval fish assemblages (LFA) in summer off the Catalan coast, an area with a wide array of environmental conditions.

Reproductive inequalities in the acanthocephalan Corynosoma cetaceum: looking beyond "crowding" effects [PDF]

, 2018
Background: At present, much research effort has been devoted to investigate overall (average) responses of parasite populations to specific factors, e.g., density-dependence in fecundity or mortality. However, studies on parasite populations usually pay

Metal levels inTrachurus trachurusandCyprinus carpioin Turkey

Food Additives & Contaminants: Part B, 2013
Concentrations of five toxic metals were determined in two fish species from Turkish cities during 2010-2011. The obtained lead concentrations for all of the studied Trachurus trachurus (mean 777 μg kg(-1)) and Cyprinus carpio (mean 439 μg kg(-1)) samples were found to be higher than the maximum level (ML) of 300 μg kg(-1), while Cd concentrations in ...

Long‐Term Dynamics of the Northern Humboldt Current System Pelagic Fish Community: A Look Into Community Shifts

Marine Ecology, Volume 46, Issue 5, September/October 2025.
ABSTRACT The northern Humboldt Current System (nHCS) has high environmental variability that impacts key demographic and community‐scale processes. Understanding the role and ecological implications of these interannual or long‐term events is crucial in describing the dynamics of the nHCS community. Using catch data from pelagic assessment surveys from

Impact of environmental factors on recruitment and hatching patterns of Horse Mackerel (L.) collected in a nearshore rocky reef system

Frontiers in Marine Science, 2015
Horse mackerel (Trachurus trachurus, Linnaeus, 1758) is a highly exploited fish species, common throughout the North-East Atlantic. As a pelagic-neritic fish it typically occurs over the shelf at 100-200 m depth on sandy bottom and most research has ...
