Genetics key to maximum growth rate for shrimp

Realizing higher growth rates in commercially cultured shrimp has many important benefits, including reducing various risks, cutting costs and increasing economic opportunities. Shrimp genetics primarily determines the amount of additional growth that can be achieved, as shrimp typically reflect their 


The Bottom Line: Feeds and water quality revisited

Uneaten or undigested feed and their metabolic byproducts contribute to declines of water quality in aquaculture systems. Accordingly, feed and feeding techniques require continuous review. Reducing overfeeding is an important opportunity for improving feed conversion ratios. 


Feed trays: The good, the bad, the ugly

Feed trays are typically used to avoid overfeeding in aquaculture production systems. They are sometimes used to deliver 100 percent of the feed that is fed, and other times a small number of trays are used as a guide to
