White shrimp study compares commercial feed attractants

Microbial flocs spare protein in white shrimp diets

The authors conducted a study to determine how reducing the protein content of a diet would affect the growth performance of L. vannamei reared in an experimental microbial floc culture system. 


Mutton snappers grow well on plant-based diets
