چکیده
A comprehensive understanding of the reproductive biology and spawning activity of the tuna is necessary for sound management of this complex and important fishery. Current methods for assessing maturity schedules of tunas is based on the conventional approach of collecting gonads for detailed histological examination. While this method has proven to be accurate and provides valuable information, it is laborintensive, expensive and lethal for the fish. In addition, this conventional approach is completely unsuitable to fishery-dependent assessments, since gonadal samples are often unavailable. The most challenging feature of the histological approach is that it is time consuming, thus making it impractical to evaluate the population annually. As a result, management models are static and fail to reflect ‘real-time’ effects of fishing pressure or environmental perturbations.

1. Purpose of the project and indicative results. The main objective of the project is to provide reliable estimates of delayed mortality and morbidity in sea turtles following interactions with longline fishing gear. To do this, we will deploy pop-up satellite archival tags (PSATs) on incidentally-caught turtles. The tags have a fail-safe/mortality sensor, whereby the tag can be set to jettiso...

1. Purpose of the project: Previous modeling suggests that tuna productivity in the western and central Pacific Ocean is tied to upwelling along the equator in the central and eastern Pacific. This project proposes to test this hypothesis by combining diet analysis, stable isotopic analyses, and food-web modeling to study trophic-level variation and tuna movements in the equatorial Pacific. Our...
