(2019-03-15)
Sludges from Submerged Biofilter (SBF) and Aerobic Three Phase Airlift Fluidized Bed Reactor with Circulation in Concentric Tubes (AAFBR-CT) wastewater treatment of recirculating aquaculture systems (RAS) were evaluated ...
Modeling optimum levels of balanced digestible protein for adult pacu (Piaractus mesopotamicus) and the development of an economic optimization procedure for different marketing strategies of the final yield
(2020-09-15)
Marketing strategies and feeding costs are key factors affecting the sustainability of intensive aquaculture systems. The present 44-day feeding trial aimed to model the optimum levels of balanced digestible protein (BDP) ...
Determinación del flujo de agua para la biorremediación en sistemas acuícolas recirculados utilizando tapetes microbianos construidos
(2015-09-01)

Eficiência na remoção de NAT, DBO e DQO utilizando reator aeróbio de leito fluidizado com circulação em tubos concêntricos associado ao decantador de coluna em uma produção intensiva de tilápia
(2016-07-01)
The development of intensive aquaculture is accompanied by an increasing environmental impact produced by the wastewater generated. The recirculating aquaculture systems (RAS) are a compact alternative and manage high ...
A comparison of larval production of the northern scallop, argopecten purpuratus, in closed and recirculating culture systems
(ELSEVIER SCI LTD, 2009)
Northern scallop Argopecten purpuratus aquaculture relies on an efficient all year-round larval supply. Larvae are generally produced in closed aquaculture systems (CAS) using the batch techniques with periodical water ...
