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.
Change the aquafeed paradigm by viewing feed as an investment, instead of simply as a cost. This can result in greater profitability.
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.
The authors designed changes for single- and twin-screw extruders that streamlined the extrusion process to achieve higher output rates for small-diameter aquafeeds.
