Rearing method and daily otolith ring of Japanese sardine larvae.

NIPPON SUISAN GAKKAISHI, 1989
Japanese sardine larvae Sardinops melanostictus hatched out from field-collected eggs, were successfully reared for 30 days with the survival rate of 13% of initial egg number. The relation between rearing days (D) and number of sagittal otolith rings (N) was expressed by the linear regression of N=0.99D-1.88 based on the 31 reared larvae, and the ...

After All, Size Does Matter: Size and Trachemys Scripta Reproduction Traits at the Western Limit of Its European Distribution

Integrative Zoology, EarlyView.
‐ Female T. scripta exhibit a clear size‐dependent reproductive investment, where larger plastron length is positively associated with all key reproductive traits. ‐ Female T. scripta reach sexual maturity at a plastron length of approximately 15–18 cm. ABSTRACT In invasive species, reproductive success may determine invasion outcomes and influence the

Understanding Japanese sardine migrations using acoustic and other aids [PDF]

ICES Journal of Marine Science, 1996
The migration routes of the Japanese sardine in the Kuroshio and Oyashio transition area were investigated using acoustic aids, satellite images, aerial observations, and commercial catch data. Japanese sardine schools were distributed in warm streamers, especially at their heads, where phytoplankton and zooplankton biomass were most heavily ...

Analysis of historical dark data shows multiple regime changes among pelagic migratory fishes around Japan over 120 years

Frontiers in Marine Science
An analysis of long-term (over-100-year) continuous catch data at local to regional scales (tens to hundreds of kilometres) is needed to deepen our understanding of the interaction between regime shifts of multiple fish species and marine environmental ...

Grades of 43 Fish Species in Japan Based on IgE-binding Activity

Allergology International, 2006
Background: Hypersensitivity reactions to fish are a common food allergy, but IgE-binding activity to fish species have not been fully elucidated. The aim of this study was to identify fish with high binding activity to IgE in sera from Japanese fish ...

Endotoxins and Biological Implications—Review

Public Health Challenges, Volume 5, Issue 4, December 2026.
Graphical overview of endotoxin sources, exposure routes, biological effects, detection methods, and routes of elimination. ABSTRACT Endotoxins, also known as lipopolysaccharides (LPSs), are structural components of the outer membrane of Gram‐negative bacteria and some cyanobacteria.

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

Fish and Fisheries, Volume 27, Issue 6, Page 1245-1268, November 2026.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.
