Natal Homing and Connectivity in Atlantic Bluefin Tuna Populations

Science, 2008
Atlantic bluefin tuna populations are in steep decline, and an improved understanding of connectivity between individuals from eastern (Mediterranean Sea) and western (Gulf of Mexico) spawning areas is needed to manage remaining fisheries. Chemical signatures in the otoliths of yearlings from regional nurseries were distinct and served as natural tags ...

Climate Attribution in Fishery Stock Assessment: Case Studies From the Northeast U.S. Groundfish Stocks

Fish and Fisheries, EarlyView.
ABSTRACT Climate change poses an unprecedented risk to fisheries ecosystems and economies globally. Ocean warming has led to observed geographic shifts and changes in the productivity of fish stocks. Due to the rapid pace of change in many of the world's oceans, there is a critical need to develop and apply scientific knowledge and tools that can help ...

Spawning behaviour and post-spawning migration patterns of atlantic bluefin tuna (Thunnus thynnus) ascertained from satellite archival tags. [PDF]

PLoS ONE, 2013
Spawning behaviour of Atlantic bluefin tuna (Thunnus thynnus) was investigated using electronic satellite tags deployed in the western Mediterranean spawning ground, around the Balearic Islands (years 2009-2011).

A new satellite technology for tracking the movements of Atlantic bluefin tuna [PDF]

Proceedings of the National Academy of Sciences, 1998
The movements of Atlantic bluefin tuna ( Thunnus thynnus thynnus ) have captured the interest of scientists and fishers since the time of Aristotle. This tuna is unique among bony fish for maintaining elevated body temperatures (21°C above ambient) and attaining large size (up to 750 kg). We describe here the use of

Impacts of Ocean Acidification on Reproduction and Early Life Development in Marine Teleost Fish—A Synthesis

Fish and Fisheries, EarlyView.
ABSTRACT Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist.

Study on the catch, bycatch and discard of Chinese pelagic longline fisheries in the Atlantic Ocean

Aquaculture and Fisheries
Catch, bycatch and discard information is important for the assessment and management of fisheries. Using Chinese pelagic tuna longline observer data from 2010 to 2018, we studied the catch composition in the Chinese pelagic tuna longline fisheries in ...

Spatially explicit estimates of stock sizes, structure and biomass of herring and blue whiting, and catch data of bluefin tuna [PDF]

Earth System Science Data, 2015
The North Atlantic is a productive marine region which has supported important commercial fisheries for centuries. Many of these fisheries have exploited the pelagic species, including herring, blue whiting and tuna.

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

Fisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Stable Isotope–Enabled Particle Drift Models Predict Where High‐Resolution Isotope Analyses Can Discriminate Among Larval Trajectories in Atlantic Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...
