Reproductive Relationships of the Pacific Stock of Japanese Anchovy Engraulis japonicus
NIPPON SUISAN GAKKAISHI, 2000 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。

The Occurrence of Microplastic Ingestion in Commercial Marine Fish in Miri, Sarawak, Malaysia
Environmental Quality Management, Volume 35, Issue 4, Summer 2026.ABSTRACT Microplastics are polymer‐based particle compositions of various toxic chemicals with size less than 5 mm. Due to their small size, microplastics can be ingested and accumulate in body tissues of organisms. This raises concerns about their toxicity being transferred to humans via food consumption.

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.ABSTRACT Growth and haematological parameters are used in aquaculture as indicators of the health of cultivated fish in response to changes in diet and the physicochemical conditions of the water. In this study, the physiological status of Totoaba macdonaldi was evaluated based on growth, haematological parameters and blood chemistry in response to two

Degeneration of postovulatory follicles in the Iberian sardine Sardina pilchardus: structural changes and factors affecting resorption [PDF]
, 2007 Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To

Environmental DNA, Volume 8, Issue 2, March/April 2026.Novel species‐specific eDNA qPCR assay for endangered Hong Kong Grouper (Epinephelus akaara) reveals low shedding rates and rapid decay. Rare, trace detections across Hong Kong waters confirm population rarity, demonstrating eDNA as a powerful non‐invasive tool for monitoring threatened marine fishes. ABSTRACT The Hong Kong Grouper (Epinephelus akaara)

Contemporary Methods for Capturing Juvenile Salmonids in the Marine Environment
Fish and Fisheries, Volume 27, Issue 2, Page 160-178, March 2026.ABSTRACT Anadromous salmonids play vital roles in marine and freshwater ecosystems. The most abundant of these fishes—Pacific salmon (Oncorhynchus spp.)—are integral to coastal ecosystems and communities across the North Pacific Rim, but numerous populations are experiencing dramatic declines, particularly towards the south of their range.
