The effect of temperature on the duration of spawning markers—migratory-nucleus and hydrated oocytes and postovulatory follicles—in the multiple-batch spawner Japanese flounder (Paralichthys olivaceus) [PDF]

open access: yes, 2011
The duration of spawning markers (e.g. signs of previous or imminent spawnings) is essential information for estimating spawning frequency of fish. In this study, the effect of temperature on the duration of spawning markers (i.e., oocytes at early ...

Observations on the reproductive behaviour of Japanese anchovy Engraulis japonica in captivity.

open access: yesNIPPON SUISAN GAKKAISHI, 1989
Behavioural observations of spawning of Japanese anchovy Engraulis japonica in a tank were made during the night using a high-sensitivity TV-system. Some anchovy began vigorously pursuing one after the other 30 min or 1h before spawning. During spawning hours, pursuits were observed in numbers much greater compared with the number of females spawning ...

Polymorphic microsatellite loci for the Japanese anchovy Engraulis japonicus (Engraulidae).

open access: yesGenetics and molecular research : GMR, 2011
We isolated and characterized 14 polymorphic microsatellite loci in the Japanese anchovy (Engraulis japonicus) using a (GT)(13)-enriched genomic library. The numbers of alleles per locus ranged from 6 to 31, with a mean of 17.8. The observed and expected heterozygosities ranged from 0.180 to 0.949 and from 0.172 to 0.966, with means of 0.731 and 0.825,

Genetic Analysis of the Populations of Japanese Anchovy (Engraulidae: Engraulis japonicus) Using Microsatellite DNA [PDF]

open access: yesMarine Biotechnology, 2002
We analyzed the population structure of the Japanese anchovy (Engraulis japonicus), a small pelagic fish, using 6 microsatellite DNA loci. The anchovy is known to have 2 separate spawning populations, one near northeastern Taiwan in the Pacific Ocean and the other near southwestern Taiwan in the Taiwan Strait.

A Review of the South Pacific Tuna Baitfisheries: Small Pelagic Fisheries Associated with Coral-Reefs [PDF]

open access: yes, 1989
A review is given of current information concerning small pelagic fishes exploited for tuna bait in the South Pacific. These fishes are usually caught over or near coral reefs using light attraction and lift nets.

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

open access: yesFrontiers 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 ...

Exploring the Effects of Internal and External Factors on the Early Growth of Anchovy (Engraulis japonicus) in the Yellow Sea Based on Otolith Microstructure

open access: yesProgress in Fishery Sciences
The abundant and widely distributed resources of small pelagic fish in marine ecosystems constitute significant targets for commercial fisheries. The Japanese anchovy (Engraulis japonicus) is a prominent representative of small pelagic fish and is ...
