Interannual Variations in Distribution and Density of Japanese Anchovy (Engraulis japonicus) Larvae in the Shelf‐Break Region of East China Sea During Spring (2001–2022)

Fisheries Oceanography, Volume 35, Issue 5, Page 777-794, September 2026.
ABSTRACT Japanese anchovy (Engraulis japonicus) is the most abundant fish in the East China Sea (ECS) and an important fishery resource throughout its life stages. Using samples collected along the ECS shelf‐break in April over a 22‐year period (2001–2022), we examined the horizontal distribution and interannual variability of larval density (mean ...

Distribution and growth of Scomber japonicus and S. australasicus larvae in the southern East China Sea in response to oceanographic conditions [PDF]

Marine Ecology Progress Series, 2010
Chub mackerel Scomber japonicus and spotted mackerel S. australasicus are important fishery resources in the countries adjacent to the East China Sea (ECS). During February to March in 2004 and 2005, based on species identification using PCR-restriction fragment length polymorphism (PCR-RFLP) analysis of mtDNA, we examined the larval distribution ...

The postlarvae of spotted mackerel Scomber australasicus CUVIER (Pisces, Scombridae).

NIPPON SUISAN GAKKAISHI, 1984
The postlarvae of S. australasicus were collected by larva net during 2 cruises in the seas off southern Japan and northern South China Sea (Feb.-Mar. 1973), and East China Sea (Mar. 1982). It was found that they possess distinctive dorsal melanophores just below the origin of body muscle in shoulder throughout the postlarval stage, not seen in the ...

Mass capture fishing in the Marquesas Islands

Archaeology in Oceania, Volume 59, Issue 2, Page 234-250, July 2024.
ABSTRACT Mass capture of small fishes with a variety of nets, traps, and weirs was widely practiced and economically important across East Polynesia at western contact. Archaeological research, however, has suggested these technologies were less important during the early settlement period and gained prominence over time. Several explanations have been

Fish weight reduction in response to intra‐ and interspecies competition under climate change

Fish and Fisheries, Volume 25, Issue 3, Page 455-470, May 2024.
Weight reduction in the fish assemblage was observed in the 1980s associated with the biomass peak of the Japanese sardine indicating the effect of intra‐ and interspecies competition. Another weight reduction was observed in the 2010s associated with a moderate increase in the biomass of the Japanese sardine and chub mackerel under stronger ...

Intelligent assessment of the histamine level in mackerel (Scomber australasicus) using near-infrared spectroscopy coupled with a hybrid variable selection strategy

LWT, 2021
Abstract Determination of the histamine level in fish is essential not only because it is an indicator of fish freshness but also because this prevents the risk of histamine intoxication in consumers. This study used the strategy of near-infrared (NIR) spectroscopy coupled with a hybrid variable selection for rapid and nondestructive assessment of ...

Magnesium isotopic variation in marine fish organs

Progress in Earth and Planetary Science
Magnesium is a macro-nutrient for all living organisms, and its stable isotope ratios (δ26Mg) can be used for analyzing feeding habits and the dynamics of elements within the body. However, it was still unclear what kind of conditions for feeding and the

Carbon isotopic changes of 16 proteinogenic amino acids during trophic transfer in a cultured marine consumer

Progress in Earth and Planetary Science
Stable carbon isotopic compositions of amino acids (δ 13CAA) in organisms potentially record information on carbon sources and flow in food webs. In this study, we report δ 13C values of 16 proteinogenic amino acids in marine consumers and evaluate their
