An integrated approach to historical population assessment of the great whales: case of the New Zealand southern right whale

Creator:: Jackson, Jennifer A., Carroll, Emma L., Smith, Tim D., Zerbini, Alexandre N., Patenaude, Nathalie J., and Baker, C. Scott
Abstract:: Accurate estimation of historical abundance provides an essential baseline for judging the recovery of the great whales. This is particularly challenging for whales hunted prior to twentieth century modern whaling, as population-level catch records are often incomplete. Assessments of whale recovery using pre-modern exploitation indices are therefore rare, despite the...

Accounting for Transient Dynamics Improves use of Marine Protected Areas as a Reference Point for Fisheries Management

Creator:: Quennessen, Victoria I.
Abstract:: Fisheries management that is based on quantitative assessment has commonly relied on estimating the unfished biomass of a fished stock to compare current and historical population size. Developing predictive models for this requires many years of catch and abundance data. Smaller, new, or mainly recreational fisheries may not have the...

Bias and Precision of Estimates from an Age-Structured Stock Assessment Program in Relation to Stock and Data Characteristics

Creator:: Yin, Yanshui and Sampson, David B.
Abstract:: Assessments for many U.S. Pacific coast groundfish stocks have been developed using the statistical catch-at-age method known as Stock Synthesis. This study used Monte Carlo simulation and a fractional factorial experiment to evaluate the effects of input data errors and stock characteristics on bias and precision in estimates of ending...

Development of a Standardized DNA Database for Chinook Salmon

Creator:: Seeb, L. W., Antonovich, A., Banks, Michael A., Beacham, T. D., Bellinger, M. R., Blankenship, S. M., Campbell, M. R., Decovich, N. A., Garza, J. C., Guthrie III, C. M., Lundrigan, T. A., Moran, P., Narum, S. R., Stephenson, J. J., Supernault, K. J., Teel, D. J., Templin, W. D., Wenburg, J. K., Young, S. F., and Smith, C. T.
Abstract:: An international multi-laboratory project was conducted to develop a standardized DNA database for Chinook salmon (Oncorhynchus tshawytscha). This project was in response to the needs of the Chinook Technical Committee of the Pacific Salmon Commission to identify stock composition of Chinook salmon caught in fisheries during their oceanic migrations. Nine...

A bioenergetics model to evaluate demographic consequences of disturbance in marine mammals applied to gray whales

Creator:: Villegas-Amtmann, S., Schwarz, L. K., Sumich, J. L., and Costa, D. P.
Abstract:: While sophisticated tools are used to monitor behavioral changes of large marine vertebrates, determining whether these changes are meaningful for management and conservation is challenging. The Population Consequences of Disturbance model proposed a bioenergetics model to detect biologically meaningful population responses, where disturbance costs are linked to lost energy. The...
