Osteological development in the Japanese sardine,Sardinops melanostictus
Ichthyological Research, 1997The development of all osteological elements, except scales, of the Japanese sardine,Sardinops melanostictus, is described from newly-hatched larvae to adult fishes. Newly-hatched larvae lacked osteological elements. Part of the head skeleton began to develop in 53 hour old larvae (4.2 mm in notochord length [NL]). Larvae at the first-feeding stage (77

Time-varying relationships between early growth rate and recruitment in Japanese sardine
Fisheries Research, 2020Abstract Growth is an important factor that regulates survival during early life stages, and growth rates and recruitment are often thought to be positively related. However, environmental conditions generally fluctuate over time, which could lead to temporal changes in growth–recruitment relationships. Here, we investigate whether growth–recruitment

Concentration of Ethyl Icosapentaenoate From Japanese Sardine Oil by Molecular Sieve Column
Fette, Seifen, Anstrichmittel, 1984AbstractThe concentration of icosapentaenoic acid ethyl ester from Japanese sardine oil by the column of molecular sieve 10X was studied. It was found that the molecular sieve column was effective on the concentration of ethyl icosapentaenoate from Japanese sardine oil.

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).

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.

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.

Abstract Coastal-ocean–open-ocean migrations, prey–predator relations and long-term population dynamics of chum salmon (Oncorhynchus keta) and Japanese sardine (Sardinops melanostictus), associated with large-scale climate and oceanographic conditions, are reviewed.

Management of declining Japanese sardine, chub mackerel and walleye pollock fisheries in Japan
Fisheries Research, 2009Abstract Japanese sardine ( Sardinops melanostictus ), chub mackerel ( Scomber japonicus ), and the northern Japan Sea of walleye pollock ( Theragra chalcogramma ) stocks have fallen to very low levels in Japan since the early 1990s. We review existing management measures for these stocks from the view point of an ecosystem approach.

Variations in food abundance for Japanese sardine larvae related to the Kuroshio meander
Fisheries Oceanography, 1994ABSTRACTLong‐term fluctuations of chlorophyll a concentration, and abundance of herbivorous or omnivorous small copepods during the spawning season of the Japanese sardine, Sardinops melanosticta, were examined in relation to the types of Kuroshio meander.
