Reproductive Biology of Female Pacific Halibut (Hippoglossus stenolepis) in the Gulf of Alaska

چکیده
Developing a robust understanding of Pacific halibut reproductive biology is essential to the different components (e.g. maturity) that determine output species and, therefore, for estimating relative female spawning biomass. With these, effective and proactive management strategies can be designed implemented face large-scale environmental changes which high-latitude fish are particularly vulnerable. To date, studies have mainly focused on population or regional scales, leaving specific details organism-level development unexamined. The work described here aimed address information gaps in by conducting detailed histological examination temporal ovarian over an annual cycle with special attention use biological indicators ( e.g. oocyte diameter, gonadosomatic index, hepatosomatic Fulton’s condition factor, somatic fat) characterizing developmental stages phases. Our results provide foundation future directed at improving current maturity estimations assessment explore models test utility predict this important species.

Dispersal and behavior of Pacific halibut Hippoglossus stenolepis in the Bering Sea and Aleutian Islands region
Currently, it is assumed that eastern Pacific halibut Hippoglossus stenolepis belong to a single, fully mixed population extending from California through the Bering Sea, in which adult halibut disperse randomly throughout their range during their lifetime. However, we hypothesize that hali but dispersal is more complex than currently assumed and is not spatially random. To test this hypo thesi...

متن کاملStable isotope variations in otoliths of Pacific halibut (Hippoglossus stenolepis) and indications of the possible 1990 regime shift
Stable oxygen and carbon isotope ratios ( 18O and 13C) from archived otoliths of Pacific halibut, Hippoglossus stenolepis, were measured to examine the most recent regime shifts in British Columbia and the Gulf of Alaska. 18O values of these otoliths ranged from −1.5 to +2.8‰ VPDB, and were consistent with the life stages and migration behavior of halibut. 13C varied from −3.3 to +0.9‰ VPDB, bu...
