Development of sense organs in the Japanese sardine Sardinops melanostictus
Fisheries Science, 2001: The developmental processes of the olfactory organ, taste buds, lateral line system, and inner ear in the Japanese sardine Sardinops melanostictus were examined in reared and wild specimens. Both the ciliated and microvillous receptor cells in the olfactory organ were found shortly after hatching.

Ecological Modelling, 2009
A two-dimensional individual-based model coupled with fish bioenergetics was developed to simulate migration and growth of Japanese sardine (Sardinops melanostictus) in the western North Pacific. In the model, fish movement is controlled by feeding and spawning migrations with passive transport by simulated ocean current.

The purpose of this study was to clarify the seasonal variation of fatty acid composition and free amino acid content in the Japanese sardine (Sardinops melanostictus) from the sea of Hyuga-Nada, and the relationship between the fatty acid composition of this sardine and that of plankton in the area.

Large schools of Japanese sardines,Sardinops melanostictus, mate in single pair units at night
Environmental Biology of Fishes, 1996We observed the behavior of the spawning group of Japanese sardine,Sardinops melanostictus, in the field at night, and also confirmed the spawning behavior in the darkness in captivity. The chasing and mating were done in a pair of 1 male and 1 female. The 1-to-1 mating was a definite finding irrespective of the group density in the field, the density ...

AbstractNon‐stationary driver‐response relationships are increasingly being recognized by scientists, underlining that a paradigm shift out of conventional stationary relationships is crucial. Japanese sardine (Sardinops melanostictus, Clupeidae) is a typical small pelagic fish in the northwestern Pacific with considerable fluctuations in productivity,

Canadian Journal of Fisheries and Aquatic Sciences, 1999
The relationship between the population size of the Japanese sardine, Sardinops melanostictus, and sea surface temperature (SST) from 1979 to 1994 was studied. Significant positive correlations were found between the natural mortality coefficient during the period from the postlarval stage to age 1 and winter-spring SST in the Kuroshio Extension and ...

This study assessed the stock-recruitment relationship (SRR) for the Japanese sardine Sardinops melanostictus in the North-western Pacific. Of the 20 SRR models investigated, the Akaike information criterion (AIC) was the minimum (AIC=551.2) when the data were separated into two groups (A and B) and the log-normal distribution was applied as the error ...

Regimes and stock-recruitment relationships in Japanese sardine (Sardinops melanostictus), 1951-1995
Canadian Journal of Fisheries and Aquatic Sciences, 1998We used reproductive success, rather than abundance or catch, to identify regimes because reproductive success responds faster to environmental changes. Peak abundance of Japanese sardine during 1951-1995 was about 1000 times higher than minimum abundance.

Marine Biology, 1997
Growth trajectories of individual larvae of Japanese sardine, Sardinops melanostictus, caught in the coastal waters off western Japan were back-calculated from the first feeding stage up to date of capture (approximate size of 20 to 35 mm total length; TL) based on individually determined allometric relationships between otolith daily ring radii and ...

Population decline off the Japanese sardine Sardinops melanostictus owing to recruitment failures
Canadian Journal of Fisheries and Aquatic Sciences, 1995The Japanese sardine Sardinops melanostictus started to decline after 1989. Recruitment to age 1 population was small in four year-classes from 1988 to 1991. The population decline after 1989 resulted from recruitment failures in 4 consecutive years. Egg production was high in the years of poor recruitment.
