Production of trimethylamine-N-oxide (TMAO) via the gut microbiota has recently been proposed as an important pathophysiological mechanism linking ingestion of 'unhealthy foods', such as beef (containing carnitine) and eggs (containing choline), and the development of atherosclerosis. Hence, TMAO has gained attention as a novel biomarker for cardiovascular disease. However, fish and seafood con...

Abstract Climate change and deoxygenation are affecting fish stocks on a global scale, but disentangling the impacts of these stressors from effects overfishing is challenge. This study was conducted to distinguish between climate mismanagement as possible causes for drastic decline in spawning stock size reproductive success cod ( Gadus morhua ) herring Clupea harengus Western Baltic Sea, when...

Pacific herring (Clupea pallasi) are an abundant and important component of the coastal ecosystems for the west coast of North America. Current Canadian federal herring management assumes five regional herring populations in British Columbia with a high degree of exchange between units, and few distinct local populations within them. Indigenous traditional knowledge and historic sources, howeve...

Different populations of Atlantic herring are regarded as forming a metapopulation, but we know little about the dynamics of the connectivity and degree of interbreeding between the populations. Based on data from three periods between 1962 and 2011, we identified the presence of two components of herring in a small semi-enclosed coastal marine ecosystem based on different somatic growth patter...

Atlantic salmon (Salmo salar L.) populations exist in about 80 rivers draining to the Baltic Sea. Salmon reproduction has ceased in many rivers due to anthropological changes in river conditions and in some cases salmon stocks have been lost due to overfishing. To compensate for losses in smolt production, large-scale smolt releases into rivers have been carried out since the 1950s in the Balti...

Received 24 October 1996 Revised version accepted for publication 30 January 1997 Abstract Recently, a deletion of chromosome 4pter was found in three patients with PittRogers-Danks syndrome. We investigated two of these patients, by means of DNA and FISH studies, together with two additional patients with Pitt-Rogers-Danks syndrome, to determine the critical region of the deletion in these pat...

Viral haemorrhagic septicaemia virus (VHSV) has, in recent decades, been isolated from an increasing number of free-living marine fish species. So far, it has been isolated from at least 48 fish species from the northern hemisphere, including North America, Asia and Europe, and fifteen different species including herring, sprat, cod, Norway pout and flatfish from northern European waters. The h...

Biodiesel is a non-petroleum fuel designed to run in a diesel engine. It can be made from a variety of different feedstocks, including virgin vegetable oil, waste cooking oil, and animal fats. The aim of this research was to compare and contrast biodiesel made from fish oil to other more traditional sources. In this paper I examined traditional biodiesel feedstocks available in coastal Alaska. ...
