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 degrees C above ambient) and attaining large size (up to 750 kg). We describe here the use of a pop-off satellite tag, for investigating the Atlantic-wide movements an...

This paper represents a review of different tagging activities carried out on bluefin tuna (Thunnus thynnus) in the eastern Atlantic and Mediterranean Sea. Except in Croatia where tagging has been done on captive specimens, all other tagging campaigns, performed within framework of joint European Tuna Tagging Programme, have been done on bluefin tuna released in the open sea. Besides the taggin...

Tag release and recapture data of bigeye (Thunnus obesus) and yellowfin tuna (T. albacares) from the Hawaii Tuna Tagging Project (HTTP) were analyzed with a bulk transfer model incorporating size-specific attri­ tion to infer population dynamics and transfer rates between various fishery components. For both species, the transfer rate estimates from the offshore handline fishery areas to the lo...

The stomach contents of 68 Atlantic bluefin tuna (Thunnus thynnus) landed in Port Hood and Canso, Nova Scotia, in 2010, were analyzed to characterize the diet of bluefin tuna at the two locations. Of the sampled fish, 54 stomachs had contents. Pelagic schooling fish such as herring (Clupea harengus) and mackerel (Scomber scombrus) dominated the diets in both regions. However, a number of rare s...

The orange-red spectrum of  the skin of  electric yellow (Labidochromis caeruleus) is  one  of  the  idealistic and  necessary  schemas sought  by  aquarists  and commercial producers. In this study, the effect of live foods meal on the skin coloration of juvenile electric yellow was examined. 270 fish with an average living body weight was 0.42 ± 0.11 g, and average total length was 3...

The TUNA Challenge was a set of three shared tasks at REG’08, all of which used data from the TUNA Corpus. The three tasks covered attribute selection for referring expressions (TUNA-AS), realisation (TUNA-R) and end-toend referring expression generation (TUNAREG). 8 teams submitted a total of 33 systems to the three tasks, with an additional submission to the Open Track. The evaluation used a ...

The objective of this study was to examine if individual variation in morphological characters is related to swimming costs in wild and domestic brook charr, and in wild yellow perch. Our results indicate that absolute swimming cost was higher in wild and domestic brook charr individuals having a stout body shape, and these individuals are therefore less efficient swimmers. These results are co...

Large-scale (100s km) distributions of tuna larvae (family Scombridae), particularly of the commercially important genera Thunnus and Katsuwonus, have been extensively investigated because of the need to identify spawning locations and the possibility of estimating spawning stock biomass from surveys of larvae (Strasburg, 1960; Richards, 1976; Scott et al., 1993). Despite this effort, and the a...
