Trend in catch and current Japanese sardine Sardinops sagax biological status
Fisheries, 2022Nowadays, after a long period of depression, Japanese sardine (Sardinops sagax) is on the rise. At a high stock level, this species expands its range, migrating to high-productivity Northwest Pacific Ocean areas, where it becomes available to Russian fishery. The article analyzes the long-term catches, as well as provides fishery catches data for 2021.

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).

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

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 ...

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.

Selective retention and transfer of long-chain polyunsaturated fatty acids in Japanese sardine
Marine Biology, 2021Essential fatty acids are suggested to be key elements in trophodynamic processes in small pelagic fish. Small pelagic fish generally acquire these fatty acids from phytoplankton and zooplankton lipids; however, little is known about the utilization characteristics of fatty acids.

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.

Deep Sea Research Part II: Topical Studies in Oceanography, 2005
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.

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.
