Complete mitochondrial DNA sequence of the Japanese sardine Sardinops melanostictus +
Fisheries Science, 2000SUMMARY: We determined the complete nucleotide sequence of the mitochondrial genome for a Japanese sardine, Sardinops melanostictus (Teleostei: Clupeiformes). The entire genome was purified by gene amplification using long polymerase chain reactions (PCR), and the products were subsequently used as templates for PCR with 30 sets of fish-versatile ...

Two female-specific serum proteins (FSSPs) were detected immunologically in estradiol-treated Japanese sardine Sardinops melanostictus. The major FSSP was demonstrated to be a high molecular estradiol-inducible glycolipophosphoprotein with an immunological relation to a major yolk protein, and was suggested to be vitellogenin (VTG).

The spectral absorbance of photoreceptor visual pigments and the opsin gene class of the visual pigments was investigated in Sardinops melanostictus. Microspectrophotometric (MSP) measurements showed that the rod photoreceptors had peak absorbance spectra (λmax) at 502 nm. The spectral sensitivity of single cones was centered at 393 nm.

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,

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.
