Abstract:
Aquaculture has been recognized as a vital supply of protein to meet the rising global demand; therefore, the stock quality of farmed fish is crucially important to deliver necessary nutrients to the consumer. Aggression among farmed fish is a known issue linked to poor stock quality and welfare. To investigate this issue, we develop a novel swarming model that introduces aggressive interactions among fish to simulate conditions that better approximate the aquaculture environment. We find that a new phase transition emerges, revealing new swarming structures and events not found in the classical homogeneous swarms. The new swarm dynamics cause an overall rise in fish lactic acid that depends nonlinearly on fish density. This, by proxy, signifies reduced flesh quality and increased exhaustion.
