  • Case study - Viet-Uc, Vietnam

    One of the best known growth stories in Vietnamese aquaculture is shrimp producing company Viet-Uc. The business, run by entrepreneur Van Thanh Luong, has set up the world’s largest shrimp hatchery producing 15 billion of postlarvae annually. Applying hatchery management principles – controlling conditions from start to finish – to the nursery and grow-out stages, Viet-Uc is ...

  • Case study - Boonsawang, Thailand

    While shrimp and prawn production still represent the highest volumes in Thailand, an increasing number of farms started to diversify into other species. Private hatcheries and nurseries now supply the market with weaned fry for species such as barramundi and sea bass. Boonsawang Co. in Chonburi, owned by Suthi Mahalao, also exports fry to Vietnam, Malaysia, Singapore, Taiwan, Australia and ...

  • Case study - Nordic Halibut, Norway

    The Nordic Halibut company in Norway – world leader in Atlantic halibut production – worked closely with colleagues, competitors and even the local government to install a 360° quality control system including environmental studies, water quality monitoring and automated feeding technologies. The result is a highly productive farming system that is now finally reaching ...

  • Case study - Peixe Vivo, Brazil

    Seeing the rapid surge of tilapia farming in the Santa Fé do Sul region in Brazil, Emerson Esteves recognized the need to produce high quality PL to support business activity in the area. He founded Peixe Vivo: a medium-scale hatchery specialized in tilapia. A close eye for detail, controlled hygiene and temperature conditions and a thorough perfection of feeding technologies led him to ...

  • Case study - Fitmar, Mexico

    Coming from a long line of professional fisherman, the Fitmar family business made a switch from fishery to aquaculture. Seeing aquaculture as a more future proof way of supplying seafood to the local market, this was a very deliberate choice. In order to establish a professional and economically viable model, Fitmar decided to invest a lot of time and effort in optimized hatchery and nursery ...

  • Multiple stressor effects of predation by rotifers and herbicide pollution on different Chlamydomonas strains and potential impacts on population dynamics

    Environmental factors can interact with the effects of chemical pollutants on natural systems by inducing multiple stressor effects in individual organisms as well as by altering selection pressure on tolerant strains in heterogeneous populations. Predation is a stressful environmental factor relevant for many species. Therefore, the impact of predation by the rotifer Brachionus calyciflorus on ...

  • 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 ...

  • Biological diversity of peatlands in Canada

    Abstract.  Knowledge about the biodiversity of Canada’s vast peatlands is poor largely because peatlands have not been routinely differentiated from other types of habitats. Plants are better known than the animals. Systematic surveys of peatland plants began in the late 1800s, but did not begin in earnest until the 1950s. With the exception of a few marshes, peatlands are classified into ...

  • Planktonic microbial assemblages and the potential effects of metazooplankton predation on the food web of lakes from the maritime Antarctica and sub-Antarctic islands

    Antarctica is the continent with the harshest climate on the Earth. Antarctic lakes, however, usually presents liquid water, at least during part of the year or below the ice cover, especially those from the sub-Antarctic islandsand the maritime Antarctic region where climatic conditions are less extreme. Planktonic communities in these lakes are mostly dominated by microorganisms, including ...

  • Comparative Toxicokinetics of Cadmium in Artemia

    Abstract  The toxicokinetics of cadmium was determined for five populations belonging to four species of Artemia (A. salina, A. parthenogenetica, A. franciscana, and A. persimilis) using a bicompartmental model. The effects of sublethal cadmium concentration on the kinetic parameters in A. parthenogenetica were determined. The BCF values are inversely related to the concentration, as is the ...
