ABSTRACT Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist.

Grouped, stacked rods and tapeta lucida in the retina of Japanese anchovy Engraulis japonicas [PDF]
Morphology of the photoreceptor cells and tapetum of the Japanese anchovy Engraulis japonicus was studied by histologically and by chemical analysis. The Japanese anchovy has a duplex retina.

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 ...

Reproductive Relationships of the Pacific Stock of Japanese Anchovy Engraulis japonicus
カタクチイワシ本州太平洋系群の1978a1994年級の再生産関係を検討した。親の量は太平洋岸の潮岬以東の観測された産卵量, 子の量は子世代が生涯産んだ推定産卵量とした。子の量は潮岬以東の産卵量を過去の研究から推定した体重1gあたりの年間産卵量と年別成魚漁獲量の比率で分割して求めた。その再生産関係は1989年級を境に異なった。1978a1988年級群では親の量は低水準で年々の親と子の量はほぼ同量であったが, 1990a1994年級では親の量は高水準で年々の親と子の量の関係は大きく変動した。

ABSTRACT We developed and evaluated a fishery‐dependent catch‐per‐unit‐effort (CPUE)‐based proxy index for juvenile Japanese anchovy (Engraulis japonicus) recruitment‐related variability in the southeastern coastal waters of Korea. The proxy was constructed from bimonthly CPUE of the smallest juvenile size class (20–40 mm) in the anchovy drag‐net ...

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish
ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...

The Japanese anchovy Engraulis japonicus is used as live bait in skipjack pole-and-line fisheries. Japanese anchovies are transported to fishing grounds by fishing boats on voyages that can take from 4 to 50 days.

ABSTRACT The movement ecology of Trachurus japonicus in the adult stage remains poorly understood because observing their underwater behavior over long periods is challenging. This study aimed to examine vertical habitat use by T. japonicus using electronic tags. Ninety fish were tagged and released in November 2022 in Tokyo Bay, Japan.

Biosensors for Biotoxins Detection and Monitoring
This review examines state‐of‐the‐art biosensing platforms for biotoxin detection, including antibody‐, aptamer‐, CRISPR‐, nanopore‐, whole cells‐ and MIP‐based sensors. It highlights advances in ultra‐sensitive detection, real‐matrix validation in food and water, and multiplexed analysis, and discusses how the integration with machine learning ...
