  • What are the uses of analyzing fish?

    Fish, which share many physiological properties with mammals, are a highly visible part of most aquatic habitats with over 775 species in North America alone. Critical to many natural food chains, they are a source of food, recreation and economic growth and affect the plankton, macrophytes and other aquatic organisms with whom they coexist. Fish often are one of the first indicators of change ...

  • Use of sea water and hydraulic conditions. Potential cause of Mortality by Metals and Hydrogen Sulfide in Recirculation Fisheries

    The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a ...

  • Global transcriptomic profiling in barramundi Lates calcarcifer from rivers impacted by differing agricultural land‐uses

    Most catchments discharging into the Great Barrier Reef (GBR) lagoon have elevated loads of suspended sediment, nutrients, and pesticides, including photosystem II inhibiting herbicides, associated with upstream agricultural land use. To investigate potential impacts of declining water quality on fish physiology, RNASeq was used to characterize and compare the hepatic transcriptomes of ...

  • Ecological impacts of fluridone and copper sulphate in catfish aquaculture ponds

    Fluridone and copper sulphate are often used for controlling macrophytes and algae in aquaculture ponds. The present study examined the ecological effects of these chemicals on macrophyte, phytoplankton, and zooplankton biomass, plankton community structure, water quality parameters, and fish survival and yield in catfish culture ponds using a randomized complete block design. The estimated ...

  • 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. ...

  • Forecasting fish biomasses, densities, productions, and bioaccumulation potentials of Mid‐Atlantic wadeable streams

    Regional fishery conditions of Mid‐Atlantic wadeable streams in the eastern United States are estimated using the BASS bioaccumulation and fish community model and data collected by the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP). Average annual biomasses and population densities and annual productions are estimated for 352 randomly selected ...

  • Modifications of macrobenthos assemblages on land–based fish farm phytotreatment basins in the Orbetello lagoon

    In the Orbetello lagoon basin there are some intensive land–based fish–farming facilities which contribute to cause a significant cyclic development of the opportunistic chorophycea Ulva laetevirens, and consequent serious decay events in spring and summer. To minimise the nutrients' impact, fish farming was supplied with phytotreatment system. The purpose of this study was to ...

  • Synthetic estrogen directly affects fish biomass and may indirectly disrupt aquatic food webs

    Endocrine‐disrupting chemicals are known to alter the fitness of individual organisms via changes in growth, behavior, and reproduction. It is largely unknown, however, whether these effects cascade through the food web and indirectly affect other, less sensitive organisms. The authors present results from a mesocosm experiment whereby the effects of the synthetic estrogen 17α‐ethinylestradiol ...
