  • Is the chronic Tier‐1 effect assessment approach for insecticides protective for aquatic ecosystems?

    We investigated the appropriateness of several methods, including those recommended in the Aquatic Guidance Document of the European Food Safety Authority (EFSA), for the derivation of chronic Tier‐1 Regulatory Acceptable Concentrations (RACs) for insecticides and aquatic organisms. The insecticides represented different chemical classes (organophosphates, pyrethroids, benzoylureas, insect ...

  • Effects of different management regimes on mangrove ecosystem services in Java, Indonesia

    This new report, published by Wageningen University and Wetlands International, seeks to fill a significant gap in mangrove ecosystem service estimates. While several studies have sought to measure and value the ecosystem services provided by mangrove ecosystems in general, this new piece of research has for the first time conducted separate evaluations for zones that are characterised by ...

  • Implication of microRNA deregulation in the response of vertebrates to endocrine disrupting chemicals

    MicroRNAs are recently discovered small regulatory molecules that control messenger RNA (mRNA) translation in plants and animals and have been implicated in a variety of hormone‐related physiological pathways. Estrogens, thyroid hormones, and gonadotropins all are known to act on miRNA abundance to cause major shifts in cellular activity, physiology, and homeostatic control mechanisms. ...

  • Benzoylurea pesticides used as veterinary medicines in aquaculture: Risks and developmental effects on non‐target crustaceans

    Diflubenzuron and teflubenzuron are benzoylureas that are used in aquaculture to control sea lice. Flubenzurons have low toxicity to many marine species such as fish and algae, but by their nature are likely to have significant adverse effects on non‐target species such as crustaceans and amphipods. Although the exact mechanism of toxicity is not known, these compounds are thought to inhibit ...

  • Measurement of the amount of DissolvedOxygen

    Dissolved Oxygen (DO) is the term used for the measurement of the amount of oxygen dissolved in a unit volume of water. In water quality applications, such as aquaculture (including fish farming) and waste water treatment, the level of DO must be kept high. For aquaculture if the DO level falls too low the fish will suffocate. In sewage treatment, bacteria decompose the solids. If the DO ...

  • FATE AND EFFECTS OF POLY‐ AND PERFLUOROALKYL SUBSTANCES IN THE AQUATIC ENVIRONMENT – A REVIEW

    Poly‐ and perfluoroalkyl substances (PFASs) are distributed ubiquitously in the aquatic environment which raises concern for the flora and fauna in hydrosystems. This critical review focuses on the fate and adverse effects of PFASs in the aquatic environment. PFASs are continuously emitted into the environment from point and nonpoint sources such as sewage treatment plants (STPs) and ...

  • Carbon footprint of aquaculture in eastern India

    The present study was conducted to determine the carbon (C) footprint of different aquaculture production systems in India. The total input (kg CE/ha) in different cultures, respectively, was 1,811 to 4,144 for scampi, 4,417 to 5,913 for polyculture, 4,090 to 8,873 for shrimp and 2,417 to 2,786 for carp. Of the total inputs, feed accounts for around 90% of carbon equivalent (CE), in all ...

  • Augmenting aquatic species sensitivity distributions with interspecies toxicity estimation models

    Species sensitivity distributions (SSD) are cumulative distribution functions of species toxicity values. The SSD approach is increasingly being used in ecological risk assessment, but is often limited by available toxicity data necessary for diverse species representation. In this study we evaluate augmenting aquatic species databases limited to standard test species with toxicity values ...

  • The relative sensitivity of macrophyte and algal species to herbicides and fungicides: An analysis using species sensitivity distributions

    Lemna spp. are the standard test species representing aquatic macrophytes in the current risk assessment schemes for herbicides and plant growth regulators in the European Union and North America. At a Society of Environmental Toxicology and Chemistry (SETAC) workshop on Aquatic Macrophyte Risk Assessment for Pesticides (AMRAP), a Species Sensitivity Distribution (SSD) working group was formed ...

  • Hexabromocyclododecane in consumer fish from South China: Implications for human exposure via dietary intake

    Levels of hexabromocyclododecane (HBCD) were determined in 12 consumer fish species from South China. The concentrations of the sum of HBCD diastereoisomers (ΣHBCD) ranged from nondetectable to 194 pg/g wet weight, with a detectable frequency of 70%. This was at the low end of the concentration range globally observed. Carnivorous fish species contained higher HBCD concentrations than herbivorous ...

  • Assessment of aquatic habitat effect by artificial change of streambed topography

    As interest in ecosystems and the environment has recently increased, efforts for the preservation and restoration of river ecosystems have increased. The purpose of this study is to estimate the fish physical habitat by artificial change of streambed topography applying two-dimensional simulation model, River2D. A total reach length of 130 m along the Je stream located within the Geum River ...

  • Shellfish culture in Chile

    The present situation and future projections regarding shellfish culture in Chile are analysed. Production has increased exponentially, mainly of the 'Chilean mussel' Mytilus chilensis (Hupe) and the 'northern scallop' Argopecten purpuratus (Lamarck). At present, seven species are cultured, two of which were introduced. The total invertebrate production corresponding to cultures has increased ...

  • Estimating preferences for non-market attributes of aquaculture and sustainable seafood production: methods and empirical applications

    If aquaculture is to promote sustainable seafood production, the public must be willing to accept associated tradeoffs. Tradeoffs may include impacts on a variety of environmental and social attributes. Public preferences for aquaculture may differ according to type of operation, species, region, and other factors. Stated preference methods can assist policymakers in designing balanced, ...

  • Aquaculture Facilities As A Potential Source Of Antibiotic Resistance To The Aquatic Environment

    The development and proliferation of antibiotic resistance in pathogenic, commensal, and environmental microorganisms is a major public health concern. The extent to which human activities contribute to the maintenance of environmental reservoirs of antibiotic resistance is poorly understood. Aquaculture facilities are one possible source of resistance to the environment because of their ...
