There has been considerable interest during recent years in evaluating the directed commercial halibut fi shery catch-rates and comparing them with observations from the IPHC’s annual setline survey. Further, it has been more than a decade since there has been a review of the IPHC’s current method for standardizing annual fi shery logbook observations for use in the stock assessment (Clark 2002...

Administration of flumequine and oxolinic acid to halibut Hippoglossus hippoglossus by bath resulted in significant tissue levels of both the antibactenals. Bath treatment using 150 mg 1-' of flumequine and 200 mg 1-' of oxolinic acid for 72 h resulted in flunlequine concentrations of 14.2 pg g-' in muscle and 85.4 pg g-' in abdominal organ homogenate and oxolinic acid concentrations of 9.4 pg ...

We identified visual opsin genes for three flounder species, including the spotted halibut (Verasper variegatus), slime flounder (Microstomus achne), and Japanese flounder (Paralichthys olivaceus). Structure and function of opsins for the three species were characterized together with those of the barfin flounder (V. moseri) that we previously reported. All four flounder species possessed five ...

Current worldwide discussions about management regimes for natural resources are increasingly focusing on forms of knowledge: for example on the discussion on scientific knowledge versus ‘other’ forms of knowledge (Inglis 1993; Scott 1996; Kalland this issue), be it ‘local’, ‘indigenous’, aboriginal, or users’ knowledge. Many of these discussions have been highly politicised interactions betwee...

In complex ecosystem models, relationships between species include a large number of direct interactions and indirect effects. In order to unveil some simple and better understandable relationships, it is useful to study the asymmetry of inter-specific effects. We present a simple approach for this based on stochastic food web simulations from previous studies. We refer to the Prince William So...

Electronics industry is one of the fastest growing industries in the world. In India also, there are high turnovers and growing demand of electronics product especially after post liberalization in early nineties. These products generate e-waste which has become big environmental issue. Industries can handle these e-waste and product returns efficiently by developing reverse logistics (RL) syst...

Ninety-three samples of fresh and canned fish (edible part) collected from Lower Austria, Burgenland and from Viennese retail operations were analysed for mercury, lead and cadmium. The mercury contents ranged from <0,01 (limit of determination) to 0,89 mg/kg with a mean value of 0,14 mg/kg. The highest mercury contents were measured in Escolar (mean value of 0,63 mg/kg), followed by Swordfish ...

Recent EU directives and regulations for quality control and authentication of food products have prompted the development of new methods for large-scale tests to ensure the protection of consumers. In view of this, an innovative method based on MALDI-TOF mass spectrometry has been developed and successfully applied to fish authentication. Highly specific mass spectrometric profiles from 25 dif...

In this paper we introduce a class of Markov decision processes that arise as a natural model for many renewable resource allocation problems. Upon extending results from the inventory control literature, we prove that they admit a closed form solution and we show how to exploit this structure to speed up its computation. We consider the application of the proposed framework to several problems...

background: stroke is a heterogeneous disease with several risk factors. high sensitivity c-reactive protein (hscrp) is a marker for cardiovascular and cerebrovascular diseases. recent studies have shown that high hscrp level is a risk factor for ischemic stroke. the objective of our study was to investigate the association of high hscrp (> 3 mg/l) levels with ischemic stroke and its subtypes i...
