  • Samson Pumps match the strict demands of the fishing industry - Case Study

    "Samson pumps are far more robust and reliable than other pumps on the market. This is particularly important for the fishing industry," says Søren Toft Sørensen from Beva Special Svejs ApS, which specialises in the repair and servicing of large fishing vessels "It is a solid product. A really solid product, actually. The more I see what else there is on the pump market, the more ...

  • Toxicokinetics of perfluorooctane sulfonate (PFOS) in rainbow trout (Oncorhynchus mykiss)

    Rainbow trout (Oncorhynchus mykiss) confined to respirometer‐metabolism chambers were dosed with perfluorooctane sulfonate (PFOS) by intra‐arterial injection and sampled to obtain concentration time‐course data for plasma, and either urine or expired water. The data were then analyzed using a two‐compartment clearance‐volume model. Renal and branchial clearance rates (CLR and CLB; mL/d/kg) ...

  • Modeling fish production for Southern California's petroleum platforms

    California's oil platforms are nearing the end of their productive lives, and therefore will be decommissioned in the near future. These structures have been shown to be important habitat for both settlement and growth for reef fishes. Important information on the biological effects (i.e. loss of biomass and production) of different decommissioning options has not yet been explored in detail. ...

  • Bisphenol A reduces fertilizing ability and motility by compromising mitochondrial function of sperm

    Bisphenol A acts as an endocrine disruptor, affects animal reproductive success in vivo, and affects sperm functions in vitro at environmentally relevant concentrations leading to reduction in sperm motility and fertilizing ability in fish. The effect of in vitro BPA on avian sperm functions has not been explored. We tested the effect of environmentally relevant concentrations of BPA (0, 0.18, ...

  • Stop and Smell the Coral

    Marine protected areas are a popular way to try and combat the massive decline of coral reefs around the world, in part due to overfishing. But, what if, once damaged, the fish and coral you need to make the area healthy again don’t want to move back in? Turns out you might be left with a seaweed protected area. In a study published today in ...

  • The disappearing rivers of Bangladesh

    Bangladesh is a land of rivers, but changing climate has caused a third of the country’s more than 300 large rivers to disappear. The rivers are drying out as a result of barriers built upstream to divert water and protect people from floods that have become more frequent as the weather becomes more ...

  • Moving Up the Food Chain

    For most of the time that human beings have walked the earth, we lived as hunter-gatherers. The share of the human diet that came from hunting versus gathering varied with geographic location, hunting skills, and the season of the year. During the northern hemisphere winter, for instance, when there was little food to gather, people there depended heavily on hunting for survival. Our long history ...

  • 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, ...

  • Nets, nature and national parks

    Invitation to Bohuslän by Evert Taube Like blue-grey swell the Bohus mountains roll in desolate majesty against the rim of the Sea. But between its ancient bare hills is fertile land and ancient pastures. Here penetrates the Skagerrak with blue wedges and strong currents flow clear as crystal. And birch and willow stand lush and ash and oak by the barn and stables. Come, ...

  • Invasive dreissenid mussels and round gobies: A benthic pathway for the trophic transfer of microcystin

    In this preliminary study, we identify two pathways through which invasive dreissenid mussels can transfer microcystin to higher trophic levels: either directly, through consumption by benthivorous fish such as the round goby; or indirectly, through their biodeposits which are an important food source for benthic invertebrates. Our results suggest that dreissenid mussels represent a ...

  • 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 ...

  • Elite capture in local fishery management - experiences from post–socialist Albania

    Local governance based on institutions for collective action can help overcome social dilemmas in natural and agricultural resource management. A common path towards local governance is decentralisation, and within this context, a transfer of property rights from central government to local resource users. Yet, despite the successes of many decentralisation policies, the phenomenon of elite ...

  • Mercury concentrations of a resident freshwater forage fish at Adak Island, Aleutian Archipelago, Alaska

    The Aleutian Archipelago is an isolated arc of over 300 volcanic islands stretching 1,600 km across the interface of the Bering Sea and North Pacific Ocean. Although remote, some Aleutian Islands were heavily impacted by military activities from World War II until recently and were exposed to anthropogenic contaminants, including mercury (Hg). Mercury is also delivered to these islands via ...

  • Old and new knowledge combine to protect Fiji`s fish

    Efforts to protect precious marine biodiversity by combining science and local knowledge are difficult but can work, reports Naomi Antony. Along the coastline of Fiji, threatened fishing communities have been combining the ancient and the new in their fight to conserve precious marine resources. Together with traditions remembered from centuries ago and community approaches ...
