Continuing Long‐Term Shifts in Larval Fish Phenology in the Southern California Current Ecosystem Are Matched by Rapid Advances in the North

Global Change Biology, Volume 31, Issue 3, March 2025.
Using two datasets with multiple decades of data, we find that larval fish in the northeast Pacific are, on average, appearing earlier in the year over time. These shifts can be partially explained by shifts in the seasonality of ocean temperature, upwelling, and prey abundance.

Stochastic surplus production and length-based assessment models to compare Maximum Sustainable Yield advice for the Moroccan Atlantic chub mackerel

Frontiers in Marine Science
Fisheries management needs to ensure that resources are exploited sustainably and the risk of depletion is at an acceptable level. In developing countries, multi-gear, multispecies fisheries often lack data, making conventional stock assessment ...

Automatic Discrimination between Scomber japonicus and Scomber australasicus by Geometric and Texture Features

Fishes, 2018
This paper proposes a method for automatic discrimination of two mackerel species: Scomber japonicus (chub mackerel) and Scomber australasicus (blue mackerel). Because S. japonicus has a much higher market price than S.

Monitoring Fish Bacterial Pathogens of Wild Fish Species From the South China Sea by Applying Next‐Generation Sequencing on Gill Tissue

Journal of Fish Diseases, Volume 48, Issue 2, February 2025.
ABSTRACT The classic epidemiological triangle model of host—environment—pathogen is recently being reshaped into a tetrahedron, with the growing understanding of the importance of the microbiome in this array. The gills, being a gateway into the fish body, bearing an important role in fish homeostasis, host a complex microbiome that reflects the ...

Investigations on Target Strength Estimation Methods: A Case Study of Chub Mackerel (Scomber japonicus) in the Northwest Pacific Ocean

Fishes
Target strength (TS) is an acoustic property of individual marine organisms and a critical factor in acoustic resource assessments. However, previous studies have primarily focused on measuring TS at narrowband, typical frequencies, which cannot meet the

The Fish Funnel: A Trawl Modification to Reduce Fish Escapement [PDF]

, 1989
In the Gulf of Mexico there is a need to assess the potential of underutilized fish resource stocks before a commercial fishery develops. Standard sampling trawls used in the Gulf are ineffective for sampling the resource, so larger, high opening, bottom

Reducing discards in a demersal purse-seine fishery [PDF]

, 2008
Fisheries bycatches and discards constitute a significant problem in many fisheries worldwide. Unlike the pelagic purse-seine, the demersal purse seine usually targets high commercial value demersal species such as sea breams ( e.

Hormonal regulation of the phenotype into environmentally appropriate pace‐of‐life syndromes

Fish and Fisheries, Volume 26, Issue 1, Page 16-29, January 2025.
Abstract The risk of predation is an important driver that tailors life histories in various ways. Using an evolutionary model based on hormonal control, we study how different predation regimes affect adaptive risk‐taking and growth in fish populations.
