On the reproductive biology of the western Atlantic bluefin tuna, Thunnus thynnus
<p>The Atlantic bluefin tuna, Thunnus thynnus, is a highly migratory species capable of traversing great distances throughout the North Atlantic Ocean, but spawning is known to occur only in the Mediterranean Sea and the Gulf of Mexico/Straits of Florida. The regulatory body charged with managing …

Tracking diet and movement of Atlantic bluefin tuna (Thunnus thynnus) using carbon and nitrogen stable isotopes
<p>Atlantic bluefin tuna (ABFT; Thunnus thynnus) are important top predators in pelagic ecosystems. Understanding their diet and movements is necessary for proper management, but existing methods are costly and logistically challenging. Naturally occurring stable isotopes have been used to study …

Somatic condition, growth and distribution of Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Maine
<p>Atlantic bluefin tuna (Thunnus thynnus), a highly migratory apex predator, utilize temperate feeding grounds to place their tissues into positive lipid balance following reproduction and subsequent migration to northern latitudes. Commercial fishermen target Atlantic bluefin tuna between June …

The implementation of a management procedure approach to set catch limits for the Southern Bluefin Tuna and the Atlantic Bluefin Tuna
… (MP) approach to set catch limits for two bluefin tuna species: Southern bluefin tuna (SBT - Thunnus maccoyii ) and Atlantic bluefin tuna (ABFT - Thunnus thynnus). The thesis reviews possibilities and advances proposals for the implementation of this approach in two international tuna …

The evolution of virulence in Candida auris determined through experimental, ecological and epidemiological approaches
… Patch ocean plastic waste, including C. auris in Atlantic bluefin tuna (Chapter 4). I then examined the genotype of echinocandin refrac- tory clinical isolates, identifying features of heteroresistance and tol- erance associated with polyploidy (Chapter 5). Finally, I update the global genomic …

Behavioural Ecology of Large Tuna
… across 400+ species (Chapter 2). It then uses Atlantic bluefin tuna (Thunnus thynnus, ABT), large migratory apex predators with exceptional physiological capacity, as a model system to examine behavioural responses to stressors operating across contrasting temporal scales. Chapter 3 documents …

Distribution, growth, and transport of larval fishes and implications for population dynamics
… expectation. Chapter 3 presents evidence of tuna spawning inside a large no-take marine protected area, the Phoenix Islands Protected Area (PIPA). Despite variation in temperature and chlorophyll, the larval tuna distributions were similar amongst years, with skipjack (Katsuwonus pelamis) and …
