  • Fish Farms - Inspections below the surface

    Fish farms are tackling the increased demand for aquatic food, while underwater drones are tackling regular and ongoing inspections to ensure fish health and the integrity of the enclosures. According to the Food and Agriculture Organization of the United Nations, by the year 2050, there will be nearly 2 billion more humans populating the earth. Meaning that we will need to produce ...

  • Biological water treatment in aquaculture by means of “Mutag BioChip™ RAS Process“

    Aquaculture or fish farming means the artificial breeding and raising of aquatic creatures. They include fish as well as crustaceans and shellfish, which are raised and stocked under controlled conditions by using techniques and technologies offering an increased level of productivity which cannot be realized under natural conditions. Due to the increased demand for freshly caught fish and ...

  • The characteristics of immobilized granular sludge in the laboratory-scale stable partial nitrification-Anammox aquaculture water reactors

    Immobilized granular sludge is of key importance for highly effective operation of partial nitrification and anaerobic ammonium oxidation (PN-Anammox) reactors. An observation and analysis on the composition of immobilized granular sludge in each reactor was conducted by using scanning electron microscopy (SEM) and fluorescence in situ hybridization. It was indicated that the diversity of ...

  • 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. ...

  • CO2 Removal and Stripping Column Ventilation Rate at Bell Aquaculture

    Monitoring and controlling CO2 level in Recirculating Aquaculture Systems (RAS) is crucial not only for fish health but it is used increasingly for efficient management. Under supervision of Steve Summerfelt, a joint project has studied costs savings with optimizing ventilation based on CO2 continuous monitoring. The CO2 probe used in that project came from ...

  • 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 ...

  • 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, ...

  • 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 ...

  • Animation: restoring eroded coast Java by Building with Nature

    Northern Java's coasts suffer from severe erosion. In one decade, some coastal areas have retreated by three kilometres. Developmnet of coastal infrastructure and aquaculture went hand in hand with the removal of protective mangrove forests and the disturbance of sediment flows towards the coast and floodplains. Replanting of mangroves has not been successful, as the sediment balance is too ...

  • 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 ...

  • State of the Art Information on Mangrove Ecosystems in Indonesia

    Status and Trends of Mangroves in Indonesia GENERAL CONDITION OF MANGROVES IN INDONESIA Indonesia is a tropical archipelago with coastlines measuring a total length of 95,181 km, making it the country with the fourth longest coastline in the world (EarthTrends WRI, 2003, and Rompas, RM.2009). All along the coast are the estuaries of ...

  • 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 ...

  • 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 ...

  • Open sea-based Aquaculture case study

    Salmon farming is a multi-billion dollar global industry facing considerable difficulties posed by growing pressure from environmental regulatory bodies. Because marine organisms grow on and “foul” synthetic nets, oxygen available to fish is reduced and infectious diseases and parasites can spread among the fish. A test to study the reduction of fouling formation on netting of fish ...

  • Performance of an in-situ rotating biological contactor in a recirculating aquaculture system

    The start-up and activation of a nitrifying rotating biological contactor (RBC) and its performance inside a culture tank of rainbow trout were studied. First, in a lab-scale operation, the system was fed with a synthetic medium containing a high ammonia concentration (567 mg NH4+-N L−1) and operated at a high hydraulic retention time (HRT) (6.5 days) to minimize the wash-out of the biomass and ...
