Average energy use for all species considered in the LCA studies was roughly 26 GJ/ton of production of live ﬁsh. 56 EJ. 4 EJ in 2008; this estimate was based primarily on energy used for producing and delivering feeds. 8% of total energy use for aquaculture calculated from the LCA studies mentioned above. Of course, aquaculture conducted without feeding represents a large fraction (probably about 67%) of total production, and feeds make up a greater percentage of total energy use of feed-based production than they do of the average value estimated above.

Store feeds in a cool, dry place to avoid spoilage and use before expiration date suggested by manufacturer. Do not apply more feed than the culture species will consume to minimize the amount of uneaten feed. Quite often providing a ration that is in slight restriction relative to the amount considered necessary for maximum growth will reduce wasted feed and improve overall feed utilization. Do not practice water exchange in culture systems, or reduce water exchange to the lowest amount necessary.
