Illuminating the conditions for global governance to have precipitated the devastating decline of one of the ocean’s most majestic creatures The International Commission for the Conservation of Atlantic Tunas (ICCAT) is the world’s foremost organization for managing and conserving tunas, seabirds, turtles, and sharks traversing international waters. Founded by treaty in 1969, ICCAT stewards what has become under its tenure one of the planet’s most prominent endangered fish: the Atlantic bluefin tuna. Called “red gold” by industry insiders for the exorbitant price her ruby-colored flesh commands in the sushi economy, the giant bluefin tuna has crashed in size and number under ICCAT’s custodianship. With regulations to conserve these sea creatures in place for half a century, why have so many big bluefin tuna vanished from the Atlantic? In Red Gold, Jennifer E. Telesca offers unparalleled access to ICCAT to show that the institution has faithfully executed the task assigned it by international law: to fish as hard as possible to grow national economies. ICCAT manages the bluefin not to protect them but to secure export markets for commodity empires—and, as a result, has become complicit in their extermination. The decades of regulating fish as commodities have had disastrous consequences. Amid the mass extinction of all kinds of life today, Red Gold reacquaints the reader with the splendors of the giant bluefin tuna through vignettes that defy technoscientific and market rationales. Ultimately, this book shows, changing the way people value marine life must come not only from reforming ICCAT but from transforming the dominant culture that consents to this slaughter.

For years bluefin tuna has been the poster child for overfishing and poor management. However, recent improvements in data collection, catch monitoring and international cooperation are providing an opportunity to reverse the perception of a fishery that is doomed to collapse. Stock assessments are conducted routinely to monitor the abundance and productivity of exploited fish stocks so managers can determine how many fish can be sustainably harvested each year. Should a stock be declared overfished or under-going overfishing, the science behind stock assessments also equip managers with the knowledge necessary to make decisions about what short-term and long-term management measures should be taken to help reverse these trends. in that light, the goal of my research has been to use newly available age data to improve the quality and reliability of assessments for Atlantic bluefin tuna by reducing uncertainty about the data and methods used to infer growth and age composition. A secondary goal has been to provide managers with the knowledge necessary to implement effective stock rebuilding programs for Pacific bluefin tuna. Chapter 2 is focused on cohort slicing, a method routinely used in the Atlantic bluefin tuna assessment to estimate catch-at-age from catch-at-size information. This chapter explores how errors in cohort sliced catch-at-age data can bias estimates of total mortality rate derived from catch curve analysis. Recommendations are provided concerning the appropriate mortality estimator and plus group to use depending on the parameters characterizing the stock. Chapter 3 provides updated growth estimates for western Atlantic bluefin tuna, which were adopted in 2017 as the basis for defining growth in the assessment. Chapter 4 provides an overview of the theory behind age-length keys with particular emphasis on the assumptions that govern each method and provides notes of caution concerning their applications to real data. Chapter 5 evaluates through simulation the relative performance of different methods for estimating age composition of western Atlantic bluefin tuna catches and applies the best performing technique, the combined forward-inverse age-length key, to actual western Atlantic bluefin tuna data. Chapter 6 moves over to the Pacific and focuses on evaluating the potential impacts of different minimum size regulations on the stock of Pacific bluefin tuna and explores ways in which to minimize short-term pain to the industry while still achieving long-term yield and conservation goals. Overall, this work has contributed major improvements to the stock assessment process of Atlantic bluefin tuna and implications of this work resonate beyond the bluefin tuna world to other highly migratory species faced with similar problems.

This open access book is an original contribution to the knowledge on fishing and research associated with one of the most enigmatic fish of our seas: bluefin tuna, Thunnus thynnus (L.). Based on available evidence, it reconstructs the possible methods used to catch large spawners in the Strait of Gibraltar thousands of years ago and describes the much more recent overfishing that led to a great reduction in the catches of the trap fishery on the area and the disappearance of the northern European fisheries. It is the first book to relate the overfishing of juvenile fishes in certain areas to the decline of large spawners in other very distant areas, revealing one of the main underlying causes of this decline, which has remained a mystery to the fishing sector and scientists alike for over 50 years. This finding should serve to prevent similar cases from arising in the future.
