The more frequent occurrence of both marine and freshwater toxic algal blooms and recent problems with new toxic events have increased the risk for illness and negatively impacted sustainable public access to safe shellfish and recreational waters in Washington State. Marine toxins that affect safe ...
Vibrio parahaemolyticus is a marine microorganism that can cause seafood-borne gastroenteritis in humans. The infection can be spread and has become a pandemic through the international trade of contaminated seafood. Strains carrying the tdh gene encoding the thermostable direct hemolysin (TDH) and/or ...
The vertebrate genome is a result of two rapid and successive rounds of whole genome duplication, referred to as 1R and 2R. Furthermore, teleost fish have undergone a third whole genome duplication (3R) specific to their lineage, resulting in the retention of multiple gene paralogs. The more recent ...
Background Aflatoxin B1 (AFB1) is a mycotoxin produced by Aspergillus spec. The latter are worldwide contaminants of food with mutagenic and carcinogenic activities in animals and humans. AFB1 was shown to have deleterious effects on metabolism of eukaryotes in many model systems, including the ability ...
A method for reducing parasites in aquatic animals is provided. The method includes reducing a plurality of parasites infecting an aquatic animal by administrating to the aquatic animal a compound comprising propyl propane thiosulfonate (PTSO) having the formula R-SOa-S-R, where R represents n-propyl ...
Described are engineered strains of the oleaginous yeast Yarrowia lipolytica capable of producing an oil comprising greater than 50 weight percent of eicosapentaenoic acid [""EPA""], an ω-3 polyunsaturated fatty acid, measured as a weight percent of total fatty acids [""% TFAs""] and having a ratio ...
Device for automatic head/tail fin orientation of fish, where flow of fish with random head/tail fin orientation obtain a uniform orientation. The device comprises a roll (1) which rotates with a flow of fish (3) guided onto the roll prior to or at the uppermost poit (A), and a receiving system (2) ...
End plate (30) for an electric machine (1), comprising: a bearing receptacle (40) in which a magnetic bearing which is configured for rotatably mounting a rotor (20) of the electric machine (1) can be accommodated; and a radially outwardly pointing circumferential contour (50) on which a number of at ...
It is proposed a wing releasing system for releasing at least one wing (12c) of a set of wing or wings of a navigation control device (40), the navigation control device being adapted for controlling the depth and/or the lateral position of a towed acoustic linear antenna (20a) and comprising a body ...
It is proposed an operation managing system for managing the operation of a navigation control device (40). The navigation control device is adapted for controlling the depth and/or the lateral position of a towed acoustic linear antenna (20a) and comprising a body (11) to which is attached a set of ...
An increase in ocean noise levels could interfere with acoustic communication of marine mammals. In this study we explored the effects of anthropogenic and natural noise on the acoustic properties of a dolphin communication signal, the whistle. A towed array with four elements was used to record environmental ...
Aquaculture is currently one of the fastest growing food-producing sectors, accounting for around 50% of the world's food fish. Limited resources, together with climatic change, have stimulated the search for solutions to support and sustain the production of fish as a nutritious food. The integration ...
The Venus clam, Cyclina sinensis, is one of the most important bivalves in China. In recent years, increasing expansive morbidity has occurred in breeding areas, imposing significant losses on the national economy. To understand the molecular mechanisms of immune-related genes, we analyzed and sequenced ...
Emerging infectious diseases are a key threat to wildlife. Several fungal skin pathogens have recently emerged and caused widespread mortality in several vertebrate groups, including amphibians, bats, rattlesnakes and humans. White-nose syndrome, caused by the fungal skin pathogen Pseudogymnoascus destructans, ...
Background The growing concern regarding the use of agricultural land for the production of biomass for food/feed or energy is dictating the search for alternative biomass sources. Photosynthetic microorganisms grown on marginal or deserted land present a promising alternative to the cultivation of ...
Background This batch study deals with the relation between lipid as well as triglyceride contents in Nannochloropsis salina and variation in culture conditions such as nitrogen concentration and temperature. Results The tested parameters caused reduction in growth expressed as cell count, optical ...
Nannochloropsis oculata is a marine-water microalgae that is considered to be a good source of omega-3 fatty acids, specifically eicosapentaenoic acid (EPA), utilized in the production of an omega-3 oil for use as a dietary supplement. This study investigates the safety of N. oculata in male and female ...
Unlike migratory seabirds with wide foraging ranges, resident seabirds forage in a relatively small range year-round and are thus particularly vulnerable to local shifts in prey availability. In order to manage their populations effectively, it is necessary to identify their key prey across and within ...
As coastal species experience increasing anthropogenic pressures there is a growing need to characterise the ecological drivers of their abundance and habitat use, and understand how they may respond to changes in their environment. Accordingly, fishery-independent surveys were undertaken to investigate ...
Bottlenose dolphin stock structure in the northeast Atlantic remains poorly understood. However, fine scale photo-id data have shown that populations can comprise multiple overlapping social communities. These social communities form structural elements of bottlenose dolphin (Tursiops truncatus) populations, ...
