Fishery Biology of the Japanese Anchovy in the Waters off the Boso Peninsula-II

open access: yesNIPPON SUISAN GAKKAISHI, 1968
In order to observe the process of maturation and the number of eggs to be discharged during the spawning season, 175 specimens of female Japanese anchovy taken off BosoPeninsula during February through July 1966 and April through June 1967 were examined.

Difference in Black-tailed Gull (Larus crassirostris) diet during the breeding season for the last 10 years in the South Sea of Korea [PDF]

open access: yesJournal of Ecology and Environment, 2013
Sea temperature in the South Sea of Korea has been increased over the last decades. Seabirds are sensitive to changes in food availability in marine environment.

De novo transcriptomes of olfactory epithelium reveal the genes and pathways for spawning migration in japanese grenadier anchovy (Coilia nasus). [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: Coilia nasus (Japanese grenadier anchovy) undergoes spawning migration from the ocean to fresh water inland. Previous studies have suggested that anadromous fish use olfactory cues to perform successful migration to spawn.

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 ...

Effect of sea water temperature on egg size of Japanese anchovy.

open access: yesNIPPON SUISAN GAKKAISHI, 1987
Egg size change of Japanese anchovy dependent upon sea water temperature is described. Length of chorion was selected as the representative egg size character based on comparisons with some other characters, and referred to as egg diameter. Egg diameter changed seasonally and geographically.

Swimming angle and target strength of larval Japanese anchovy (Engraulis japonicus) [PDF]

open access: yesFisheries Science, 2011
The swimming angle of larval Japanese anchovy (Engraulis japonicus) was measured in a tank, and target strength (TS) was calculated using a theoretical scattering model. The mean swimming angle was 12.8° (SD ±22.1). Increased speeds of flow led to increased mean swimming angles.

The Niches of the Far Eastern Sardine and Japanese Anchovy

open access: yesAsian Fisheries Science, 1992
The mean spawning seasons and locations and food items in stomachs of the Far Eastern sardine Sardinops melanosticta (Tamminck and Schlegel) and Japanese an­chovy Engraulis japonica (Houttuyn), which were considered as three dimensions of time, habitat and resource of the niches, were examined and compared with those of the chub mackerel Scomber ...
