Bivalve culture is of considerable economic and social interest in northeastern (NE) Brazil. The polyculture is an alternative approach to traditional monoculture for reducing the environmental impact of shrimp farming and improving oyster culture. Perkinsus marinus and Perkinsus olseni were found infecting oysters in NE Brazil and can threaten oyster production. This study evaluated Perkinsus ...

Numerous studies show that semi-natural habitats within agricultural landscapes benefit native pollinating insects and increase resultant crop pollination services. More recently, evidence is emerging diversification techniques on farms, as well increased compositional configurational heterogeneity the cropped portion of landscapes, enhance pollinator communities. However, to date, only a few h...

Plankton population of shrimp and shrimp-GIFT (Genetically Improved Farmed Tilapia) culture ponds were studied. The present study was carried out to estimate phytoplankton zooplankton abundance diversity in mono polyculture systems. A total 13 genera cyanophyceae, chlorophyceae, bacillariophyceae, euglenophyceae, rhodophyceae dinophyceae recorded from the monoculture while 12 measured shrimp-ti...
