[...]the importance of farmed shrimp as a source of food, employment, and economic development is indisputable. [...]imbalance of the microbial population and toxic N-compounds issues were commonly observed, as well as the excessive concentration of suspended solids (Ray et al., 2010), poor alkalinity (Furtado et al., 2015), and C: In terms of shrimp performance, water quality parameters in optimal levels, proper feed management, and desirable microbial profile of the water are key points in BFT. [...]the use of high-quality diets associated with automatic feeders (promoting better spatial and temporal feed distribution) has improved growth and uniformity. [...]several nursery facilities were abandoned, unsatisfactory growth performance was observed, and most farmers switched to “green water” earthen pond-based nurseries (Ching et al., 2020).
