Climate Change Impacts on Atlantic Oceanic Island Tuna Fisheries

Frontiers in Marine Science, 2021
Climate change is already affecting the distributions of marine fish, and future change is expected to have a particularly large impact on small islands that are reliant on the sea for much of their income.

Reproduction of Atlantic bluefin tuna

Fish and Fisheries, 2020
AbstractThe reproductive success of fish populations depends on their reproductive potential and offspring survival to maturity. The reproductive potential affects recruitment and hence populations’ resilience and productivity. Extensive research carried out throughout the current century has improved our understanding of the reproductive biology of ...

Optimal Management of the Northern Atlantic Bluefin Tuna [PDF]

Marine Resource Economics, 2002
This paper analyzes the optimal management of the Northern Atlantic bluefin tuna, both eastern and western stocks. The analysis is based on a deterministic multi-gear and age-structured bioeconomic model. In order to assess the importance of the gear structure in this fishery, the model is optimized in two scenarios.

Timing of Increment Formation in Atlantic Bluefin Tuna (Thunnus thynnus) Otoliths

Fishes, 2022
Controversies remain regarding the periodicity, or seasonality, of otolith growth band formation, which directly influences a correct age determination of Atlantic bluefin tuna using this structure.

Culturable microbiota associated with farmed Atlantic bluefin tuna (Thunnus thynnus)

Aquatic Living Resources, 2017
This study examined culturable microbiota associated with farming of Atlantic bluefin tuna (Thunnus thynnus), an economically significant aquacultured fish species, in autumn and late spring. While sea water gave higher heterotroph plate counts than tuna

First attempt to assess the viability of bluefin tuna spawning events in offshore cages located in an a priori favourable larval habitat

Scientia Marina, 2013
Most of the Atlantic bluefin tuna caught by the purse-seine fleet in the Mediterranean Sea are transferred alive into transport cages and towed to coastal facilities where they are fattened.

Comparative assessment of the reproductive status of female Atlantic bluefin tuna from the Gulf of Mexico and the Mediterranean Sea.

PLoS ONE, 2014
Despite attention focused on the population status and rebuilding trajectory of Atlantic bluefin tuna (Thunnus thynnus), the reproduction and spawning biology remains poorly understood, especially in the NW Atlantic.

Age and growth rate of juvenile bluefin tuna Thunnus thynnus from the Mediterranean sea (Sicily, Italy)

Scientia Marina, 2005
The microstructural analysis of the sagittal otoliths of juvenile Atlantic bluefin tuna, Thunnus thynnus, can be used to estimate the age and growth rate of young-of-the-year individuals born in the Mediterranean.

Development of Single-Nucleotide Polymorphism (SNP)-Based Species-Specific Real-Time PCR Assays for Authenticating Five Highly Priced Tuna

Foods
Tuna are economically important as food resources in food markets. However, because tuna is often processed into steaks or fillets, the meat can be difficult to identify through morphological features.
