Phytoplankton community dynamics as a metrics of shrimp healthy farming under intensive cultivation

In this study, the composition and temporal dynamics of phytoplankton communities were tracked in shrimp ponds of two crops with different health status (healthy or diseased) to explore the potential relationship between phytoplankton community dynamics and/or stability and shrimp health status. Dif...
