News features and technical articles about the evolution of aquaculture, one of the world’s fastest growing industries.



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. 


Changing the aquafeed paradigm

Change the aquafeed paradigm by viewing feed as an investment, instead of simply as a cost. This can result in greater profitability.

Fishmeal-free feeds for hybrid tilapia

A series of experiments showed that fishmeal is not an essential ingredient in hybrid tilapia feeds and that plant protein-based diets can yield results similar to those obtained with diets containing 10 percent fishmeal. 


Moving toward sustainable fish feeds

The aquaculture industry has significantly reduced fishmeal levels in feeds for major farmed species. To further reduce fishmeal use, new research approaches are essential.
