Abstract:
... This is the first study to investigate the age, growth and reproductive biology of the Atlantic spadefish Chaetodipterus faber in southern Brazil. A total of 625 individuals [total length (TL) ranging from 7 mm to 510 mm] were sampled at the Paranaguá Estuarine Complex (PEC) and adjacent coastal areas over a year (August 2015 to July 2016). Age estimation based on sagittal otolith cross section sh ...

Abstract:
... Concordant with stock increase, Japanese anchovy Engraulis japonicus seems to expand its spawning ground northward from subtropical waters along the Kuroshio Current to subarctic waters affected by the Oyashio Current. However, the description of the northern expansion is still insufficient because quantitative analysis on distribution density of eggs and larvae has not been made and the mechanism ...

Abstract:
... Sablefish Anoplopoma fimbria support a lucrative fishery in the Gulf of Alaska, but their numbers have been declining despite a regulated fishery. Recruitment in A. fimbria is poorly understood due to its unusual early life history relative to many other deep-water fishes. Developmental patterns can identify critical periods during ontogeny that influence foraging and swimming abilities among indi ...
