Efficiency of aquatic macrophytes to treat Nile tilapia pond effluents
The effluents from fish farming can increase the quantity of suspended solids and promote the enrichment of nitrogen and phosphorus in aquatic ecosystems. In this context, the aim of this work was toExpand
Population structure of the bivalve Anomalocardia brasiliana, (Gmelin, 1791) in the semi-arid estuarine region of northeastern Brazil.
For several decades, the bivalve mollusk Anomalocardia brasiliana has been extracted in estuarine areas in the semi-arid region of northeastern Brazil. However, information on both dynamics andExpand

Polyculture of Nile tilapia and shrimp at different stocking densities
This study aimed to evaluate the productivity, growth performance and economic feasibility of polyculture of Nile tilapia Oreochromis niloticus and shrimp Litopenaeus vannamei at different stockingExpand
Sustainability of Nile tilapia net-cage culture in a reservoir in a semi-arid region
Abstract Among the tools used to measure sustainability in aquaculture, sets of indicators allow a holistic view of a system in its social, environmental, and economic dimensions. Approaches thatExpand
Emission and absorption of greenhouse gases generated from marine shrimp production (Litopeneaus vannamei) in high salinity
Abstract This study aimed at identifying and quantifying greenhouse gas fluxes (CH4, CO2, and N2O) in Litopenaeus vannamei shrimp nurseries submitted to different culturing conditions. The experimentExpand
Integrated multi-trophic culture of Nile tilapia (Oreochromis niloticus) and Amazon river prawn (Macrobrachium amazonicum) in brackish water
The aim of this study was to assess the feasibility of integrated multi-trophic culture of Nile tilapia (Oreochromis niloticus) and Amazon River prawn (Macrobrachium amazonicum) in brackish water byExpand
Influence of aquaculture effluents on the growth of Salvinia molesta
OBJECTIVE: Aquaculture generates social and economic benefits, but also causes impacts on the environment. One of the major impacts is the release of untreated effluents into rivers, reservoirs, andExpand
