Antimicrobials used in salmon aquaculture pass into the marine environment. This could have negative impacts on marine environmental biodiversity, and on terrestrial animal and human health as a result of selection for bacteria containing antimicrobial resistance genes. We therefore measured the numbers of culturable bacteria and antimicrobial-resistant bacteria in marine sediments in the Calbu...

A bioflocculant-producing bacterium, Bacillus megaterium SP1, was isolated from biofloc in pond water and identified by using both 16S rDNA sequencing analysis and a Biolog GEN III MicroStation System. The optimal carbon and nitrogen sources for Bacillus megaterium SP1 were 20 g L-1 of glucose and 0.5 g L-1 of beef extract at 30°C and pH 7. The bioflocculant produced by strain SP1 under optimal...

Combining GIS with neuro-fuzzy modeling has the advantage that expert scientific knowledge in coastal aquaculture activities can be incorporated into a geospatial model to classify areas particularly vulnerable to pollutants. Data on the physical environment and its suitability for aquaculture in an Irish fjard, which is host to a number of different aquaculture activities, were derived from a ...

Aquaculture is equated with the reduction of poverty in discourse advanced by intergovernmental agencies such as FAO. This discourse demands support for the promotion small-scale aquaculture through project-based interventions. There is a lack of convincing empirical evidence to support the efficacy of development interventions of this type however. Meanwhile, huge increases in cultured freshwa...

Consumer demand for affordable fish drives the ever-growing global aquaculture industry. The intensification and expansion of culture conditions in the production of several finfish species has been coupled with an increase in bacterial fish disease and the need for treatment with antimicrobials. Understanding the molecular mechanisms of antimicrobial resistance prevalent in aquaculture environ...

use of wastewater treatment methods in aquaculture is one of the main ways for decreasing the environmental effects of this industry and applies the best management practices (bmps). anionic compounds are the main pollutants in recirculation aquaculture systems. ion exchangers such as clays are vastly applied in waste water industry but in aquaculture systems at yet there isn't any report ...

The present study was conducted to examine the development and validation of sustainable indicators related to aquaculture as a social-ecological system. By reviewing the literature, it was found about 148 indicators related to sustainable aquaculture in economic (market-oriented and responsive aquaculture, capability of risk assessment and crisis management, and financial management in aquacul...

An overview of the current scientific knowledge available on climate change implications for fisheries and aquaculture is provided through three technical papers that were presented and discussed during the Expert Workshop on Climate Change Implications for Fisheries and Aquaculture (Rome, 7–9 April 2008). A summary of the workshop outcomes as well as key messages on impacts of climate change o...
