Mathematical modeling for the management of the carrying capacity of aquaculture enterprises in lakes and reservoirs
(2017-01-01)
Flooded areas of reservoirs and artificial lakes have been increasingly used for fish production; however, the waste generated by aquaculture has become a concern for the sustainable development of this activity. One of ...
Selection of sites for establishing aquaculture parks, and estimation of fish production carrying capacity, for a tropical reservoir in South America
(2017-06-01)
Actions facilitating the reconciliation of multiple uses of a reservoir with electric power generation should be implemented so as to avoid conflicts and support the best development of the water resource. In view of the ...
Effect of the carbon source on nitrifying in an activated sludge system treating aquaculture wastewater
(2015)
The nitrogen in the aquaculture wastewater can have significant effects on receiving water bodies like eutrophication and ammonia toxicity to fish communities. Removing nitrogen by nitrification-denitrification can reduce ...
Impacto das atividades de aqüicultura e sistemas de tratamento de efluentes com macrófitas aquáticas – relato de caso
(Inst Pesca, 2008-01-01)
Aquaculture effluents are enriched by nitrogen, phosphorus and organic matter and contribute to increase eutrophication of the receiving water bodies and reduction or change in biodiversity. To reduce effluent loading is ...

Transforming open mining pits into fish farms: Moving towards sustainability
(2004-08-01)
The legacy of mining activities has typically been land 'returned to wildlife', or, at some sites, degraded to such an extent that it is unsuitable for any alternate use. Progress towards sustainability is made when value ...

Microorganisms from Patagonian aquatic environments for use in aquaculture
(Springer, 2016)
Patagonian cold aquatic environments as well as their fauna harbor a scarcely explored microbial diversity with interesting characteristics for application in aquaculture. This Chapter presents the importance of microorganisms ...
Antimicrobial activity of bacteriocin-producing Carnobacterium spp. isolated from healthy Patagonian trout and their potential for use in aquaculture
(Wiley Blackwell Publishing, Inc, 2020-11)
In this study, bacteria from the intestines of Patagonian trout displaying fish pathogen antimicrobial activity were isolated and characterized. Isolates T4, T15 and M5 showed extracellular antimicrobial activity against ...
