  • Drying Sardine Fishes by Microwave Drying Machine

    1. Why Fresh Sardine Fishes Need to Be Dried by Microwave Drying Machine? Sardine fish is an important source of high-quality protein required in human diet, but it has not yet been fully utilized, due to the limited storage period and, sometimes, their strong fishy odor. Fresh sardine fish ...

  • Nets That Save Fish - Ocean bycatch isn’t inevitable — it’s a design challenge.

    Six years ago, the Norwegian coast guard filmed a Scottish fishing vessel riding gray swells, dumping 5 metric tons of dead fish back into the North Sea. Over the European Union catch quota, and so unable to keep all the fish they’d caught, the fishermen had to ditch some. To the Norwegians, who aren’t ...

  • Trophic dynamics of hexabromocyclododecane diastereomers and enantiomers in fish in a laboratory feeding study

    The in laboratory trophic transfer of hexabromocyclododecanes (HBCDs) was studied using predatory (oscar) fish and a prey species (tiger barb) exposed to a technical HBCD. Gut absorption, dynamic changes of diastereomer pattern and enantiomer fractions (EFs), and potential metabolism of HBCDs were examined. Compared to β‐ or γ‐HBCD, α‐HBCD showed lower absorption efficiency in oscar gut. A ...

  • Application of mercury isotopes for tracing trophic transfer and internal distribution of mercury in marine fish feeding experiments

    We performed feeding experiments to investigate mercury (Hg) isotope fractionation during trophic transfer and internal distribution of total Hg (THg) in marine fish upon exposure to natural seafood. Young‐of‐the‐year amberjack (Seriola dumerili) were fed with either blackfin tuna (Thunnus atlanticus) (2647 ng/g THg) or brown shrimp (Farfantepenaeus aztecus) (25.1 ng/g THg) for 80 and 50‐days, ...

  • Bioavailability of purified subcellular metals to a marine fish

    In this study, we took advantages of the supply of naturally contaminated oysters and investigated how the subcellular metal distribution and the metal burden in prey affected the transfer of metals to a marine fish, the grunt Terapon jarbua. The oysters Crassostrea hongkongensis with different contaminated histories were collected and separated into three subcellular fractions (metal‐rich ...

  • Tissue accumulation and species‐specific metabolism of technical pentabrominated diphenyl ether (DE‐71) in two predator fish

    The tissue‐specific accumulation and species‐specific metabolism of polybrominated diphenyl ethers (PBDEs) in two predator fish species (redtail catfish and oscar fish) feeding on the same prey (tiger barb) that was exposed to technical pentabrominated diphenyl ether (DE‐71) in the laboratory were investigated. The trends in the wet‐weight tissue concentration of PBDEs in two predatory fish ...

  • Evidence of impaired health in yellow perch (Perca flavescens) from a biological mercury hotspot in northeastern North America

    Few studies have investigated the effects of Hg on wild fish from remote areas, even though these fish can have high total Hg concentrations. In Kejimkujik National Park and National Historic Site (KNPNHS), Nova Scotia, Canada, concentrations of total Hg in many yellow perch (Perca flavescens) currently exceed the estimated threshold level for adverse effects in fish (0.2 µg Hg g−1 (wet wt), ...

  • Malaysia: Strong demand for ornamentals - Case Study

    The ornamental fish cultured at this Malaysian farm are exported primarily to the U.S.A. The average stocking rate in the 100 ponds of varying size is 10,000 pieces. Survival is 70 to 80 percent. Factors such as size, color and species set the ornamental’s value. Colorful males are worth more money and in greater demand. This farmer depends on the AIRE-O2® aerator’s good oxygen ...

  • Communities, knowledge and fisheries of the future

    The 'human dimension' in fisheries management has historically been incorporated via a specific economic understanding of fisheries wedded to a single-species approach. Meeting the challenge of fisheries, however, will require a broadening of fisheries science towards an ecosystems-based approach. There is also the need for a parallel shift in social science understandings of fishing towards ...

  • Recovering from overexploitation: the European fisheries of the North Sea

    In the last two decades, the fisheries of the North Sea have experienced substantial declines in the population of a number of commercially harvested species. The fisheries have also experienced the development of considerable overcapacity as a result of ineffective management and subsidies. Management of the fishery is complicated by the existence not only of multiple species and gears, but also ...

  • Open access in a spatially delineated artisanal fishery: the case of Minahasa, Indonesia

    The effects of economic development on the exploitation of renewable resources are investigated in settings where property rights are ill defined or not enforced. This paper explores potential conservation implications from labor and product market developments, such as enhanced transportation infrastructure. A model is developed hat predicts individual fish catch per unit effort based on ...

  • Molecular evolution of haemoglobins of polar fishes

    The Arctic and the Antarctic differ by age and isolation of the respective marine faunas. Antarctic fish are highly stenothermal, in response to stable water temperatures, whereas the Arctic ones are exposed to seasonal and latitudinal temperature variations. The knowledge of the mechanisms of phenotypic response to cold exposure in species of both polar habitats offers fundamental insights into ...

  • Qualitative algal analysis from the fish-gut: Tested in the rice fish cropping system

    Abstract: Algae constitute a major proportion of fish food in rice-fish culture system. Study of algal preferences and their availability in the natural environment might be important for developing natural fish feed. Preparation of formulated feeds using under-exploited materials such as algae not only reduces production costs, but also increases procurement accessibility of locally available ...

  • In Situ Avoidance Response Of Adult Atlantic Salmon To Waste From The Wood Pulp Industry

    An accidental release of non-toxic waste from decommissioned wood pulp industry in the River Numedalslågen, Southern Norway, occurred in the upper part of the accessible stretches for anadromous fish during a study of migration behaviour of radio tagged Atlantic salmon (Salmo salar, n=32, body length 51–99 cm). The fish had completed the migration phase and initiated the resident phase ...
