Recent paper published on the growth and energetic requirements of yellowtail kingfish

27-Oct-2020 (written by Callum Donohue)

We are happy to announce that research led by Callum Donohue and Ana Sequeira has been published in the journal Aquaculture. This research, Bioenergetic growth model for the yellowtail kingfish (Seriola lalandi), provides a mathematical model to predict the energetic requirements and biochemical flux of yellowtail kingfish (Seriola lalandi), a highly valued aquaculture species. This research was conducted during Callum’s placement as a research assistant in the Sequeira lab under the Aquaspace project funded by the European Commission under the H2020 framework.

Our model predicts how fish diet can affect variables of interest to aquaculture farmers such as, food conversion ratio, protein retention and energy retention. Importantly, we show how these variables can be improved by manipulating diet composition as the fish grows. This model provides a valuable addition to the aquaculture field as it can easily be used to test how different scenarios (i.e. diet type or environmental temperature) effects yellowtail kingfish production and the excretion or consumption of nitrogen and oxygen.
