| 内容記述 | Pacific during February 1991 to December 1992 were examined. Five types of otoliths were observed: type I (no hyaline zone), type II (incomplete hyaline zone along the outer otolith edge), type lI (one complete hyaline zone), typeIV(tw o hyaline zones) and another type. Approximately 80% of the small- and medium-sized fish (<280 mm) exhibited type I otoliths, and 15.8% and 65.4% of the large-sized fish (>280 mm) showed type II and type III otoliths, respectively. Most typeIVotoliths were observed in larger fish(>314 mm). The first hyaline zone in the otoliths of small- and medium-sized fish was estimated to form during winter. Maturity, spawning and ovarian cycle of Pacific saury : The reproductive biology of Pacific saury were studied by using histological observation of gonads, collected during 1991 to 1992 from the western North Pacific (n=606). Pacific saury were multiple spanner with asynchronous oocytes developments. The smallest matured fish was 253 mm and most large-size fish (>280 mm in knob length) were considered to have spawned. Atretic oocytes of yolked and /or late stage cortical alveoli oocytes were observed in the gonad of post-spawning fish. Since, perinucleolus and early stage cortical alveoli oocytes would remain in the gonad of post-spawning fish and their fat condition recovered the same level of immature fish. | |||||||||||
