Testicular development in migrant and spawning bluefin tuna (Thunnus thynnus (L.)) from the eastern Atlantic and Mediterranean [PDF]

, 2004
Testis histological structure was studied in bluefin tuna (Thunnus thynnus) from the eastern Atlantic and Mediterranean during the reproductive season (from late April to early June).

Development and characterization of tri- and tetra-nucleotide polymorphic microsatellite markers for skipjack tuna (Katsuwonus pelamis) [PDF]

, 2012
Skipjack tuna (katsuwonus pelamis) (SJT) is the largest tuna fishery in all the major oceans around the world, and the largest marine fishery in Sri Lanka. Knowledge of genetic population structure and effective population size of SJT in the Indian Ocean

Migration dynamics of juvenile southern bluefin tuna [PDF]

Scientific Reports, 2018
AbstractLarge scale migrations are a key component of the life history of many marine species. We quantified the annual migration cycle of juvenile southern bluefin tuna (Thunnus maccoyii; SBT) and spatiotemporal variability in this cycle, based on a multi-decadal electronic tagging dataset.

Surgical tagging of Atlantic mackerel (Scomber scombrus): electroanaesthesia and survival in captivity and the field

Journal of Fish Biology, EarlyView.
Abstract Electroanaesthesia using electric fish handling gloves induced rapid and reversible sedation of Atlantic mackerel (Scomber scombrus) during surgical tagging without observable adverse effects on behaviour or tag retention. In the laboratory, survival analyses revealed that longer handling times and smaller body sizes significantly reduced ...

Individual variability in activity patterns in Atlantic halibut (Hippoglossus hippoglossus) revealed using pop‐up satellite tags

Journal of Fish Biology, EarlyView.
Abstract Understanding fish behaviour and activity patterns is essential for interpreting their ecology and the processes that shape population dynamics, yet such information remains limited for wild fishes because observing individuals in situ is challenging.

Tracking Pacific bluefin tuna (Thunnus thynnus orientalis) in the northeastern Pacific with an automated algorithm that estimates latitude by matching sea-surface-temperature data from satellites with temperature data from tags on fish [PDF]

, 2005
Data recovered from 11 popup satellite archival tags and 3 surgically implanted archival tags were used to analyze the movement patterns of juvenile northern bluefin tuna (Thunnus thynnus orientalis) in the eastern Pacific. The light sensors on archival

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

DNA‐based identification of anadromous fishes (Alosa spp., Family Clupeidae) in stomach contents of marine groundfish

Journal of Fish Biology, EarlyView.
Abstract Using DNA techniques for prey identification is an emerging approach for enhancing the precision and accuracy of trophic information. We evaluated the effectiveness of DNA‐based prey identification in conjunction with visual stomach content analysis of commercially important groundfish in the nearshore Gulf of Maine, with a focus on ...

The Story of Pacific Bluefin Tuna [PDF]

, 2013
The story of Pacific bluefin tuna is a tale of extremes. They are pursued by fishermen at every turn but largely ignored by fisheries authorities. They migrate across the world's largest ocean, but spawn in only three distinct areas.

Pacific bluefin tuna (Thunnus orientalis) bycatch in the Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract A large tuna was hooked by a Japanese longline fishery in the high seas near the Republic of Namibia. This fishing ground is mainly utilized for Thunnus albacares, Thunnus obesus and Thunnus alalunga by Japanese tuna longliners. Because the tuna was larger than the common size of these species, the specimen was sampled for genetic species ...
