Abstract The scale of current marine stakeholder activity in the North Sea is such that considerable effort is required to minimise the impact of operations conducted adjacent to one another. Impacts are typically spatial - vessels wanting to work in the same physical space at the same time, or acoustic ...
The Outer Membrane Protein (OMP) of Vibrio alginolyticus cell wall was administered intramuscularly (IM) to the tiger shrimp (Penaeus monodon Fab.) at 10, 20, 30 μg/kg bw. After 14 days infection, the tiger shrimps were challenged with 107 bacterial density of Vibrio harveyi for 24 hours. The total ...
Little is known about effects of large storm systems on mesophotic reefs. This study reports on how Typhoon 17 (Jelawat) affected Ryugu Reef on Okinawa-jima, Japan in September 2012. Benthic communities were surveyed before and after the typhoon using line intercept transect method. Comparison of the ...
Genes encoding the major histocompatibility complex (MHC) have been thought to play a vital role in the adaptive immune system in all vertebrates. The discovery that Atlantic cod (Gadus morhua) has lost important components of the MHC II pathway, accompanied by an unusually high number of MHC I genes, ...
Ghrelin is a peptide hormone that is acylated with a fatty acid, usually n-octanoic acid, at the third amino acid (aa) residue (usually a serine or threonine), and this acylation is known to be essential for ghrelin activity not only in mammals but also in non-mammals, such as fish. However, the modification ...
Teleost fishes exhibit wide and temporally stable inter-individual variation in a suite of aerobic and anaerobic locomotor traits. One mechanism that could allow such variation to persist within populations is the presence of tradeoffs between aerobic and anaerobic performance, such that individuals ...
The odorant partition coefficient is a physicochemical property that has been shown to dramatically influence odorant deposition patterns in the mammalian nose, leading to a chromatographic separation of odorants along the sensory epithelium. It is unknown whether a similar phenomenon occurs in fish. ...
Background Arrays of passive receivers are a widely used tool for tracking the movements of acoustically-tagged fish in marine ecosystems; however, the spatial and temporal heterogeneity of coral reef environments pose challenges for the interpretation of tag detection data. To improve this situation ...
Divers work in dangerous environments that place severe constraints on the types of activities that divers can accomplish. The development of a underwater robotic assistant may help a human diver accomplish tasks more efficiently and safer. However, before Underwater Human-Robot Interaction (UHRI) can ...
A novel application for Autonomous Underwater Vehicles (AUVs) is considered here: a robotic diver assistant that enables close-quarters robotic operations with human divers. A robotic diver assistant has the potential to improve the efficiency, effectiveness and safety of diver operations. The robot ...
The history of science shows a shift from single-investigator ‘little science’ to increasingly large, expensive, multinational, interdisciplinary and interdependent ‘big science’. In physics and allied fields this shift has been well documented, but the rise of collaboration in the life sciences and ...
Ocean observatories introduce demanding requirements and a variety of new complexities in the commissioning phase of a program. For the National Science Foundation's Ocean Observatories Initiative's Regional Scale Nodes (RSN) observatory program, the backbone telecommunication cables were first installed ...
Commercial shipping has been recognized as the primary vector for the introduction of nonindigenous species (NIS) into coastal environments in California, North America, and across the globe. These shipping-mediated introductions occur primarily through two mechanisms, ballast water and vessel biofouling ...
An array of 8 moorings has been deployed on the continental shelf along the coast of southeastern Australia as part of the New South Wales node of Australia's Integrated Marine Observing System. The array which was first deployed in 2008, was designed to capture the key continental shelf processes associated ...
Crayfish, lobster, and sea-water samples collected from five fishing islands on the Atlantic coast–Bight of Biafra (Bonny)–belonging to Ibaka Local Government Area of Akwa-Ibom State of Nigeria were bacteriologically evaluated on thiosulphate citrate bile-salt sucrose (TCBS) agar for Vibrio load and ...
Underground forums enable technical innovation among criminals as well as allow for specialization, thereby making cybercrime economically efficient. The success of these forums is contingent on collective action twixt a variety of stakeholders. What distinguishes sustainable forums from those that ...
Today's professionals in the maritime sectors of industry, government, and non-governmental organizations are expected to develop policy and planning options, while managing both living and non-living marine resources based upon the best available science and technology. Similarly, technologists, engineers, ...
The study examined the influence of fish oil (FO) supplementation on serum 8-hydroxy-2’-deoxyguanosine (8-OHdG) levels as indicated by DNA damage markers and total antioxidant capacity (TAC) among male cigarette smokers. This double-blind, placebo-controlled randomized study was conducted among healthy ...
Carbon dioxide (CO2) levels in the atmosphere and surface ocean are rising at an unprecedented rate due to sustained and accelerating anthropogenic CO2 emissions. Previous studies have documented that exposure to elevated CO2 causes impaired antipredator behavior by coral reef fish in response to chemical ...
“See-through” strains of medaka are unique tools for experiments: their skin is transparent, and their internal organs can be externally monitored throughout life. However, see-through fish are less vital than normally pigmented wild-type fish, which allows only skilled researchers to make the most ...
