  • The cost of feed in aquaculture production is high, but efficient feeding  is expected to reduce the cost.

    Currently, we are working on simulating the feeding behavior of fish and their growth by coupling the fish school behavior model (Boid model, see separate section) and the growth model.

    Here, the differences in growth between the following two types (A: wide-range feeding, B: narrow-range feeding) are compared by simulation.

    The final growth results are shown below. Feeding over a wide range (feeding condition A) resulted in less variation.

    We plan to use this simulation to identify the most profitable feeding method in the future.
