The influence of multiple anchored fish aggregating devices (FADs) on the spatial behavior of yellowfin (Thunnus albacares) and bigeye tuna (T. obesus) was investigated by equipping all thirteen FADs surrounding the island of Oahu (HI, USA) with automated sonic receivers (‘‘listening stations’’) and intra-peritoneally implanting individually coded acoustic transmitters in 45 yellowfin and 12 bi...

Objective: 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. Methods: 270 fish with an average living body weight was 0.42 ± 0.11 g, and averag...

a series of two experiments was conducted to study the optimum dietary protein level and protein to energy ratio of lemon fin barb hybrid larvae. in experiment 1, five isocaloric diets (4700 kcal per kg) ranging from 40 to 60% protein in 5% increments were fed to triplicate groups of lemon fin barb hybrid larvae (initial weight: 0.10 ± 0.01 mg per fish) for 21 days. weight gain of fish was prop...

We analyzed the movements of Atlantic tuna (Thunnus thynnus L.) in the Mediterranean Sea using data from 2 archival tags and 37 pop-up satellite archival tags (PAT). Bluefin tuna ranging in size from 12 to 248 kg were tagged on board recreational boats in the western Mediterranean and the Adriatic Sea between May and September during two different periods (2000 to 2001 and 2008 to 2012). Althou...

through PeakForce QNMTM, 3) correlated nanoscale AFM-based conductivity measurements are a powerful technique for nanometer-scale electrical characterization on a wide range of samples. Traditionally, these measurements have been categorized into two classes: Conductive AFM (CAFM), which covers the higher current range (sub-nA up to μA), and Tunneling AFM (TUNA), which covers the lower current ...

BACKGROUND The use of DNA barcodes for the identification of described species is one of the least controversial and most promising applications of barcoding. There is no consensus, however, as to what constitutes an appropriate identification standard and most barcoding efforts simply attempt to pair a query sequence with reference sequences and deem identification successful if it falls withi...

Bigeye tuna (Thunnus obesus Lowe, 1839) are a commercially important species of tuna inhabiting the warm waters of the Atlantic, Indian, and Pacifi c oceans. They are found across the entire Pacifi c between northern Japan and North Island of New Zealand in the west and from 40°N to 30°S in the east (Calkins, 1980; Matsumoto, 1998). Adult bigeye tuna are caught mainly by longlines, but substant...

Behavior of Salmonella and Listeria monocytogenes in raw yellowfin tuna during refrigeration and frozen storage were studied. Growth of Salmonella was inhibited in tuna during refrigerated storage, while L. monocytogenes was able to multiply significantly during refrigerated storage. Populations of Salmonella in tuna were reduced by 1 to 2 log after 12 days of storage at 5-7 °C, regardless leve...
