Optimal Strouhal number for swimming animals [PDF]

open access: yes, 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.

On the Stock of Scomber japonicus (NOUTTUYN)

open access: yesNIPPON SUISAN GAKKAISHI, 1940
Form the results of marking experiments, as well as from the records of catch according to the several body-weight classes, the survival rate of Sccmber juponicus (HOUTTUYN) was estimated to be 40 for the age of from 2 to 3 years, and 21 for the age of from 3 to 4 years.

Keeping Quality of Mackerel, Scomber japonicus, by Using Aureomycin

open access: yesNIPPON SUISAN GAKKAISHI, 1955
It has already been shown that the prolongation of storage life of the sardine was obtained by a 30-minute dip in a 10 ppm aureomycin containing brine1). The present paper deals with a similar study of the effectiveness of aureomycin to keeping quality of the mackerel.

Novel Assay for Endangered Hong Kong Grouper (Epinephelus akaara) to Assess eDNA Shedding, Decay, and Population Status

open access: yesEnvironmental 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)

Long‐Term Changes in Dominant Fisheries Species and Their Relationship With Surface Oceanic Conditions in the Waters Around the Korean Peninsula From 1980 to 2019

open access: yesFisheries Oceanography, Volume 35, Issue 2, Page 267-284, March 2026.
ABSTRACT The waters surrounding Korea are an economically–ecologically important region due to their high fishery productivity and role as seasonal migratory routes for the spawning and growth of commercially valuable species. We evaluated temporal changes in dominant fisheries species in encompassing large marine ecosystem (LME) areas 47, 48, and 50 ...
