A proof-of-concept study to evaluate the types of data that can be reliably collected by electronic monitoring (EM) on Class 1-5 purse-seine vessels.E.1.a - Evaluate potential improvement of growth model for bigeye in the EPO based on presumed annuli counts from otoliths of large fish01 Nov 2017 - 01 Nov 2019FundedObjectives:
Evaluate the potential improvement in accuracy of the growth model for bigeye in the EPO resulting from including more age-at-size data for large fishE.2.a - Investigate spatiotemporal variability in the age, growth, maturity, and fecundity of yellowfin tuna in the EPO01 Jun 2017 - 31 May 2022FundedObjectives:
Estimate age, growth, maturity, and fecundity of yellowfin from four distinct areas of the eastern Pacific for use in spatially-structured stock assessment modelsE.2.b - Workshop to evaluate differences in bigeye tuna age estimation methods and resulting growth models utilized in current stock assessments by the IATTC and WCPFC23 Jan 2019 - 25 Jan 2019FundedObjectives:
Resolve concerns about differences in age estimation methods and resulting growth models used in bigeye tuna stock assessments by IATTC and WCPFCE.3.a - Investigate geographic variation in the movements, behavior, and habitat utilization of yellowfin tuna in the EPO01 Jan 2020 - 31 Dec 2021FundedObjectives:
Evaluate geographic variation in movements, behavior, and habitat utilization of yellowfin tuna via analyses of existing archival tag data sets from several discrete areas of the EPO01 Jan 2019 - 31 Dec 2023FundedObjectives:
E.5.a - Evaluate the Pacific-wide population structure of bigeye and skipjack tunas, using genetic analyses01 Jan 2017 - 31 Dec 2020FundedObjectives:
- Obtain data that will contribute to, and reduce uncertainty in, EPO tuna stock assessments, particularly for skipjack tuna;
- Obtain information on the rates of movement, dispersion, and mixing of skipjack, yellowfin, and bigeye tunas in the EPO, and between this region and other adjacent regions of the Pacific basin; and
- Obtain estimates of sex-specific growth, mortality, abundance, selectivity, and exploitation rates for those species of tuna in the EPO
Determine whether bigeye and skipjack tuna from discrete areas of the Pacific Ocean show significant genetic heterogeneity15 Jun 2018 - 15 Jun 2019FundedObjectives:
Assess the spawning ecology of captive yellowfin tuna at the Achotines Laboratory, by estimating the number of females that contribute to single spawning events, and their spawning periodicity and frequency
