A preliminary study of physical energy distribution model of Sciaenops ocellatus under swimming conditions
This study focused on Sciaenops ocellatus in deep-water cage culture studying the changes of the main energy substances and metabolites during swimming. Based on our results, a physical energy distribution model was constructed. The main conclusions were as follows: (1) A power function relationship...
