Microconstituents were measured in otoliths of juvenile northern blue®n tuna (Thunnus thynnus) from the Mediterranean Sea and western Paci®c Ocean. Whole otoliths were analyzed by inductively coupled plasma mass spectrometry. Multivariate statistical analysis showed clear separation between the two groups. Na, Mg, Mn, and Zn were most useful in differentiating Mediterranean and Paci®c samples. ...

The world's oceans are governed as a system of over 150 sovereign exclusive economic zones (EEZs, ∼42% of the ocean) and one large high seas (HS) commons (∼58% of ocean) with essentially open access. Many high-valued fish species such as tuna, billfish, and shark migrate around these large oceanic regions, which as a consequence of competition across EEZs and a global race-to-fish on the HS, ha...

This study presents the first data on movement, habitat use and behaviour for yellowfin tuna Thunnus albacares in the Atlantic Basin. Six individuals were tracked in the Gulf of Mexico using pop-up satellite archival tags. Records up to 80 days in length were obtained, providing information on depth and temperature preferences as well as horizontal movements. Thunnus albacares in the Gulf of Me...

High-k dielectric films are of interest as alternative gate insulators for metal-oxide semiconductor devices. Inour previous study, surface morphology and leakage current distribution of high-k dielectric films(HfSixOy andZrO2) have been simultaneously investigated at the nanoscale by tunneling atomic force microscopy (TUNA) [1]. Itwas found that the dominant leakage current pat...

Between 1988 and 1998, annual tuna landings at Buenaventura (Colombian Pacific) are correlated with the sea surface temperature in the central Equatorial Pacific (r=0.78, p<0.05) and the sea level height at Buenaventura (r=0.76, p<0.05) and Balboa (Panama) (r=0.79, p<0.05). Seasonal oceanic upwelling is forced by the Panama wind jet, which may favour oceanic fisheries such as tuna. Here we firs...

The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...

In this document, different scenarios of uncertainties in a multispecies fishery are presented. Uncertainties have been considered in the estimation of the species composition of the tropical tuna catch as well as in the total catch. Although three species (yellofin, skipjack and bigeye) are involved in the tropical tuna fishery, only uncertainties in the bigeye vs skipjack have been taken into...

Tuna and tuna-like fisheries play a vital role in Indonesian livelihood, especially the archipelagic waters. However, despite importance, concern general data collection activities for tuna, i.e., limited, with incomplete scientific knowledge insufficient has hampered assessment. The purpose of this study was to analyse on how fisheries-dependent system could transform quality. For purpose, ana...

Construction and Demolition (C&D) wastes contribute the highest percentage of wastes worldwide (75%). Furthermore, ceramic materials contribute the highest percentage of wastes within the C&D wastes (54%). The current option for disposal of ceramic wastes is landfill. This is due to unavailability of standards, avoidance of risk, lack of knowledge and experience in using ceramic wastes in const...

The study calculates the fork-length to round weight (L-W) relationship and condition index (K) of fattened bluefin tuna for 6-7 months in a tuna farm in western Greece and compares these morphometric parameters with those of wild bluefin tuna using the set of measurements obtained in the context of the EU-funded research projects REPRO-DOTT & SELF-DOTT. The L-W relationship and K values found ...
