  • Monitoring Ozone (in the air) in Hatchery & Fish Farm Ozone Injection Systems

    Hatcheries, fish farms and such in the aquaculture industry require clean water to maintain a high survival rate while rearing aquatic animals. Contaminated water increases the risk of infection which in turn can compromise production. A common way to disinfect water is by generating ozone on-site with an ozone generator, which is commonly inside an ozone generator room. For human safety, ...

  • Embryotoxicity of maternally‐transferred methylmercury to fathead minnows (Pimephales promelas)

    Mercury is a ubiquitous environmental contaminant and potent neurotoxin. In aquatic environments, mercury can be transformed into methylmercury (MeHg), which bioaccumulates in aquatic food webs, including fish. MeHg has been shown to transfer from female fish to developing eggs; however, relatively little is known regarding effects of maternally‐transferred MeHg on fish embryos. Here, we ...

  • Assessment of interactive effects of elevated salinity and three pesticides on life history and behavior of southern toad (Anaxyrus terrestris) tadpoles

    Because habitats are increasingly exposed to multiple stressors simultaneously, assessing the interactive effects of stressors is crucial for understanding how populations respond to human‐altered habitats. Salinization of freshwater habitats is increasing and has the potential to interact with other stressors. Chemical pollutants also contribute to habitat degradation in freshwater ...

  • Effects of pesticide exposure and the amphibian chytrid fungus on gray treefrog (Hyla chrysoscelis) metamorphosis

    Pesticides are detectable in most aquatic habitats and have the potential to alter hostpathogen interactions. The amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), has been associated with amphibian declines around the world. However, Bd‐associated declines are more prominent in some areas, despite nearly global distribution of Bd, suggesting other factors contribute to disease ...

  • Evaluating exposure and potential effects on honeybee brood (Apis mellifera) development using glyphosate as an example

    This study aimed to develop an approach to evaluate potential effects of plant protection products on honeybee brood with colonies at realistic worst‐case exposure rates. The approach comprised two stages. In the first stage, honeybee colonies were exposed to a commercial formulation of glyphosate applied to flowering Phacelia tanacetifolia with glyphosate residues quantified in relevant ...

  • Less Than 3 Percent of Oceans in Marine Parks Despite Recent Growth

    In May 1975, rising concerns about overfishing and deteriorating ocean health prompted scientists and officials from 33 countries to meet in Tokyo for the first global conference on marine parks and reserves. Noting the need for swift action to safeguard more of the sea, the delegates were unanimous in calling for the creation of a global system of marine protected areas (MPAs)—zones ...

  • Embryonic exposure to 2,3,7,8‐TCDD impairs prey capture by zebrafish larvae

    2,3,7,8‐TCDD remains a ubiquitous, persistent environmental contaminant with the potential for causing lethal deformities in larval fishes. Few studies have examined its impacts on larval growth and craniofacial development in conjunction with feeding capability. Here we use morphological and behavioral assessments to demonstrate that feeding capability of larvae is impaired even when ...

  • Effects of chronic copper exposure on development and survival in the southern leopard frog (Lithobates [Rana] sphenocephalus)

    Exposure to environmental contaminants contributes to the global decline of amphibian populations. The impacts of organic contaminants on amphibians are well documented. However, substantially less is known concerning the potential effects of metals on amphibian populations. Copper (Cu) is an essential element, but it can be toxic at concentrations only slightly higher than the normal ...

  • Clonal variation in reproductive response to temperature by a potential bulking control agent, Lecane inermis (Rotifera)

    The novel idea of using rotifers Lecane inermis (Rotifera, Monogononta) as a tool to overcome activated sludge bulking generates an on-going need to study rotifer biology. The results of biological research on rotifers can serve to improve the method so that it can be most effective when applied in treatment plants. The aim of this study was to test the effect of temperature on four selected ...

  • The Use of Ozone as a Disinfectant in Fish Hatcheries and Fish Farms

    The ever increasing load on the environment calls for more intensive measures to maintain the natural equilibrium. This is especially the case when it comes to the different life forms in rivers and lakes. In order to maintain indigenous fish populations it has become necessary in many countries to introduce stocking programs for coarse fish in addition to the ever increasing activities involving ...

  • The Herbivore Assemblage, Herbivory and Leaf Chemistry of the Mangrove Kandelia obovata in Two Contrasting Forests in Hong Kong

    Abstract  The herbivore assemblage, intensity of herbivory and factors determining herbivory levels on the mangrove Kandelia obovata (previously K. candel, Rhizophoraceae) were studied over a 13-month period at two forests with contrasting growing conditions in Hong Kong. Mai Po was part of an eutrophic embayment in the Pearl River estuary and generally offered more favourable conditions ...
