Daily growth increments in otoliths of Japanese anchovy larvae Engraulis japonica.

open access: yesNIPPON SUISAN GAKKAISHI, 1984
It was verified that daily deposition of increments in otoliths was initiated with the start of feeding in reared Japanese anchovy larvae. The range and the coefficient of variation of counts within age group were 2-5 and 6-10%, respectively and did not vary with age.

Reproductive Relationships of the Pacific Stock of Japanese Anchovy Engraulis japonicus

open access: yesNIPPON SUISAN GAKKAISHI, 2000
カタクチイワシ本州太平洋系群の1978a1994年級の再生産関係を検討した。親の量は太平洋岸の潮岬以東の観測された産卵量, 子の量は子世代が生涯産んだ推定産卵量とした。子の量は潮岬以東の産卵量を過去の研究から推定した体重1gあたりの年間産卵量と年別成魚漁獲量の比率で分割して求めた。その再生産関係は1989年級を境に異なった。1978a1988年級群では親の量は低水準で年々の親と子の量はほぼ同量であったが, 1990a1994年級では親の量は高水準で年々の親と子の量の関係は大きく変動した。

Degeneration of postovulatory follicles in the Iberian sardine Sardina pilchardus: structural changes and factors affecting resorption [PDF]

open access: yes, 2007
Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To
