World Aquaculture Magazine -December 2021

56 DECEMBER 2021 • WORLD AQUACULTURE • WWW.WA S .ORG Validating our lab results in the field is paramount because unpredictable but not rare thermal fluctuation is a reality in subtropical regions and adequate lipid nutrition has proven to be—at least in controlled conditions and constant 22 Cwater temperature—an important tool to help Nile tilapia to cope with temperature and metabolism decrease.
