Bigeye tuna are known for remarkable daytime vertical migrations between deep water, where food is abundant but the water is cold, and the surface, where water is warm but food is relatively scarce. Here we investigate if these dive patterns can be explained by dynamic optimal foraging theory, where the tuna maximizes its energy harvest rate. We assume that foraging efficiency increases with bo...

The transport of live fish is a crucial step to establish fish culture in captivity, and is especially challenging for species that have not been commonly cultured before, therefore transport and handling methods need to be optimized and tailored. This study describes the use of tuna tubes for small-scale transport of medium-sized pelagic fish from the Scombridae family. Tuna tubes are an array...

The main target species of Japanese purse seine operating in the tropical waters of the western Pacific Ocean is skipjack tuna (Katsuwonus pelamis) and yellowfin tuna (Thunnus albacares), which account for nearly 98 % of their total catch in weight and the remaining is bigeye tuna (Thunnus obesus) according to the catch based on logbook data. The recent study of the vertical distribution of the...

introduction: mcp (membrane cofactor protein or cd46) is a complement regulatory proteins (crps), which is present in most of body cell membranes (except erythrocytes), and also in most biologycal body fliuds. due to the important role of this protein in the complement system, specially in fertility, the aim of this study was to determine and isolate this protein in human seminal plasma. materi...

Purpose: We wanted to compare the treatment outcome, safety, efficacy and complications of transurethral resection of the prostate (TURP), interstitial laser coagulation (ILC), transurethral needle ablation (TUNA) and transurethral ethanol ablation of the prostate (TEAP) for the treatment of benign prostatic hyperplasia (BPH). Materials and Methods: In this prospective, randomized study, a tota...

The bluefin tuna heart remains at ambient water temperature (Ta) but must supply blood to warm regions of the body served by countercurrent vascular heat exchangers. Despite this unusual physiology, inherent difficulties have precluded an understanding of the cardiovascular responses to Ta in free-swimming bluefin tunas. We measured the heart rate (f(H)) responses of two captive Pacific bluefin...

OBJECTIVES Much of the tuna harvested in South Australia since 1990 has involved "farming" techniques requiring the use of divers. From 1993 to 1995, 17 divers from this industry were treated for decompression illness (DCI). In response, the State Government introduced corrective strategies. A decrease in the number of divers presenting for treatment was subsequently recorded. Consequently, the...

Atlantic bluefin tuna (ABFT) are highly valued and heavily exploited, and critical uncertainties regarding their population structure hinder effective management. Evidence supports the existence of two breeding populations of ABFT; a western population in the Gulf of Mexico and an eastern population in the Mediterranean Sea; both of which migrate and mix in the North Atlantic. Conventional tagg...

Long-term reduction of serum urate levels is vital in the treatment of gout. However, it is difficult to convince gout-free individuals of the necessity of treatment as few appropriate over-the-counter remedies and dietary supplements are available. Therefore, the present study aimed to investigate the antihyperuricemic efficacy and safety of a tuna extract containing the imidazole compounds to...
