Feeding Ecology and Prey Interactions of Japanese Spanish Mackerel Scomberomorus niphonius (Teleostei: Scombridae) in Korean Coastal Waters

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT The Japanese Spanish mackerel, Scomberomorus niphonius, in Korean coastal waters has exhibited a consistent increase in catches since the 1970s, peaking in 2023, driven by fishing effort, climate‐induced habitat shifts and biological factors.

A new modeling strategy for the predictive model of chub mackerel (Scomber japonicus) central fishing grounds in the Northwest Pacific Ocean based on machine learning and operational characteristics of the light fishing vessels

Frontiers in Marine Science
The chub mackerel (Scomber japonicus) is one of the most influential small pelagic fish in the Northwest Pacific Ocean, and accurate modeling approaches and model selection are critical points in predicting the Scomber japonicus fishing grounds.

Distributions and abundances of Pacific sardine (Sardinops sagax) and other pelagic fishes in the California Current Ecosystem during spring 2006, 2008, and 2010, estimated from acoustic–trawl surveys [PDF]

, 2012
The abundances and distributions of coastal pelagic fish species in the California Current Ecosystem from San Diego to southern Vancouver Island, were estimated from combined acoustic and trawl surveys conducted in the spring of 2006, 2008, and 2010 ...

Optimal Strouhal number for swimming animals [PDF]

, 2011
To evaluate the swimming performances of aquatic animals, an important dimensionless quantity is the Strouhal number, St = fA/U, with f the tail-beat frequency, A the peak-to-peak tail amplitude, and U the swimming velocity.

Evaluating Post‐Survey Otolith Subsampling Strategies for a Small‐Bodied, Fast‐Growing Pelagic Fish for Inclusion in Stock Assessments

Fisheries Management and Ecology, Volume 33, Issue 1, Page 24-39, February 2026.
ABSTRACT Identifying efficient otolith subsampling strategies that maintain data quality for stock assessments is imperative given limited resources to meet age‐estimation demands of managed fish stocks. Our objective was to evaluate the performance of three different subsampling strategies: (1) fixed otolith subsampling, (2) proportional otolith ...

Effects of density-dependence and sea surface temperature on interannual variation in length-at-age of chub mackerel (Scomber japonicus) in the Kuroshio-Oyashio area during 1970–1997 [PDF]

, 2004
Annual mean fork length (FL) of the Pacific stock of chub mackerel (Scomber japonicus) was examined for the period of 1970–97. Fork length at age 0 (6 months old) was negatively correlated with year-class strength which fluctuated between 0.2 and 14 ...

Increased expression of kisspeptin and GnRH forms in the brain of scombroid fish during final ovarian maturation and ovulation [PDF]

, 2012
BACKGROUND: Kisspeptins (Kiss) are prime players in the control of reproductive function through their regulation of gonadotropin-releasing hormone (GnRH) expression in the brain.

Determinants of Ascaridoid Nematode Infection and Anisakis‐Related Zoonotic Exposure Risk in Eastern Mediterranean Gadiformes Fishes

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Larvae of ascaridoid nematodes, particularly Anisakis spp., are common parasites of commercially important marine fishes and may represent a zoonotic hazard following ingestion of raw or undercooked seafood. We investigated the ascaridoid fauna of the sympatric European hake (Merluccius merluccius) and greater forkbeard (Phycis blennoides) from the ...

Population Genetic Structure with Mitochondrial DNA of the Chub Mackerel Scomber japonicus in Korean Coastal Waters

Journal of Marine Science and Engineering
Scomber japonicus, commonly known as chub mackerel, is a fish species of economic significance in Korea, China, and Japan, whose natural abundance has reduced dramatically due to overfishing and environmental changes.

Reproduction, age and length of first maturity of Pacific mackerel Scomber japonicus (Houttuyn, 1872) in Vizcaino Bay

Ciencias Marinas, 1994
The spawning period, length and age at first maturity of Scomber japonicus were determined from fish measuring 173 to 383 mm, sampled monthly from commercial purse-seinc catches in Vizcaíno Bay from 1984 to 1986.
