Seven species of teleost fishes comprising major prey of northwest Atlantic harbor seals were analyzed for polybrominated diphenyl ethers (PBDEs). PBDE concentrations in whole fish samples (n=87) were compared with those measured previously in harbor seal blubber to evaluate the transfer of PBDEs from prey to predator. Hexabromocyclododecane (HBCD) concentrations were measured in three fish spe...

The primary aim of the trial was to investigate the influence of menopause on the incorporation of marine n-3 PUFA into platelets and adipose tissue. A secondary aim was to evaluate whether marine n-3 PUFA may change levels of circulating oestrogens in women. Ninety-two pre- and postmenopausal women were randomly assigned to consume 2.2 g of marine n-3 PUFA or control oil daily for 12 weeks. Ad...

Total Petroleum Hydrocarbon ( TPH ) are environmental contaminants that are released into the marine environment through oil spills, industrial and domestic activities. TPH are readily transformed into more hydrophilic metabolites, which are accumulated in bile. Thus fish bile can be used as a biomarker of exposure of fish to TPH in the marine environment. in this study several stations were se...

Marine biomass including fishery products are precious protein resources for human foods and are an alternative to livestock animals in order to reduce the virtual water problem. However, a large amount of marine waste can be generated from fishery products and it is not currently recycled. We evaluated the metabolism of digested marine waste using integrated analytical methods, under anaerobic...

Introduction Photobacterium damselae is a marine gram-negative bacterium of the family Vibrionaceae, widespread in marine environments, that includes strains classified into two distinct subspecies, namely subsp. piscicida and subsp. damselae. P. damselae subsp. piscicida is the causative agent of pasteurellosis, a disease affecting a number of fish species in marine aquaculture systems worldwi...

BACKGROUND Marine stings and envenomation are fairly common in Malaysia. Possible contact to various marine life occurs during diving, fishing and food handling. Even though majority of fish stings are benign, there are several venomous species such as puffer fish, scorpion fish, lionfish, stingray and stonefish that require urgent medical treatment. Stonefish is one of the most venomous fish i...

The Holocene evolution of eight South African coastal lakes and lagoons is examined and related to changes in fish composition over that period. Historical and current connectivity with riverine and marine environments are the primary determinants of present-day fish assemblages in these systems. A small and remarkably consistent group of relict estuarine species have persisted in these coastal...

Aquaculture has been a fast-growing industry because of significant increases in demand for fish and seafood throughout the world. Its economic importance is increasing economically. Aquaculture -also known as fish or shellfish farming -refers to the breeding, rearing, and harvesting of plants and animals in all types of water environments including ponds, rivers, lakes, and the ocean. Research...

We performed a global assessment of how fish biomass has changed over the last 100 yr, applying a previously developed methodology using ecological modeling. Our assessment built on more than 200 food web models representing marine ecosystems throughout the world covering the period from 1880 to 2007. All models were constructed based on the same approach, and have been previously documented. W...

The stable nitrogen and carbon isotope ratios of bone collagen prepared from more than 100 animals representing 66 species of birds, fish, and mammals are presented. The b15N values of bone collagen from animals that fed exclusively in the marine environment are, on average, 9% more positive than those from animals that fed exclusively in the terrestrial environment; ranges for the two groups o...
