Description

This paper gives data on the biology of threadfin hakeling (Laemonema longipes) and compares year-class abundance and subarctic water regimes at 149°E for the period 1965-1990. A quasi-seven-year period, caused by the "pole" tide, is present in the variations of threadfin hakeling year-class abundance and the subarctic water regime. It is assumed that high year-class abundance of threadfin hakeling will occur in the late 1990s and early 2000s.
