Length-weight determination of fish in the aquaponics tank at Njala Univeristy

At one of our Living Labs,  length-weight determination of fish in the aquaponics tank is used for the estimation of either allometric or isometric growth and condition factors. Living lab practitioners are able to study the physiology, morphology, and life cycles of the fish giving them stable and reliable information for farming. Bi-weekly tracking has revealed a consistent weight gain indicating steady progress. The feeding protocol in the aquaponics system was optimized to correspond to 5% of the fish’s body weight. This approach reduces the need for daily weight measurements, offering a practical solution for monitoring progress. These findings not only provide essential information regarding fish growth, and serve as indicators of the system’s overall health and sustainability.
