Declines in the diversity of fish represented in British domestic recipes over the past 100 years

People and Nature, EarlyView.
Abstract Fish and shellfish are nutritionally important foods, yet consumption in many high‐income countries remains low and concentrated on a narrow set of environmentally costly species. In the United Kingdom, fish consumption is dominated by a small group of fish, the ‘Big Five’, which is often treated as an inevitable outcome of supply, convenience

Thinking of Fish Population Discrimination: Population Average Phenotype vs. Population Phenotypes

Frontiers in Marine Science, 2021
The genetic polymorphism and phenotypic variation are key in ecology and evolution. The morphological variability of the contour of fish otoliths has been extensively used for the delimitation of stocks.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Research Article Isolation and characterization of polymorphic microsatellite markers for the chub mackerel (Scomber japonicus) and cross-species amplification in the blue mackerel (S. australasicus).

Genetics and Molecular Research, 2017
In this study, 10 polymorphic microsatellite markers were developed in Scomber japonicus and were examined on 30 individuals collected from the North Pacific. The number of alleles per locus ranged from 4 to 17. The observed and expected heterozygosities per locus ranged from 0.2759 to 0.8621 and from 0.43071 to 0.9177, respectively.

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

Integrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Stock assessment of the blue jack mackerel, Trachurus picturatus, in the North‐eastern Atlantic

Fisheries Management and Ecology, 2018
AbstractA total of 49,151 blue jack mackerel, Trachurus picturatus, (Bowdich) was collected in Madeira Island (North‐eastern Atlantic) between 2002 and 2016 to evaluate possible influence of fishing on landings and reproductive parameters. A decreasing trend in the length composition was observed over the study period and length at first maturity ...

Recent Anomalously Warm Ocean Conditions and Changes in the Migration and Spawning Distribution of Chub Mackerel (Scomber japonicus) in the Western North Pacific

Fisheries Oceanography, EarlyView.
ABSTRACT Extreme ocean warming has become increasingly pronounced in the western North Pacific in recent years. Coincident with this, both the egg abundance and the catch per unit effort (CPUE) of chub mackerel (Scomber japonicus) in fisheries targeting southward‐migrating adults have decreased.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Reproductive cycle of the blue jack mackerel, Trachurus picturatus (Bowdich, 1825), off the Portuguese continental coast

Aquatic Living Resources, 2019
This work provides for the first time a description of the reproductive biology of Trachurus picturatus in Portuguese continental waters (between 41° 49′ and 36° 57′ latitude North).
