[AOS09-17] A simulation model for the neon flying squid (Ommastrephes bartramii) distribution in the Kuroshio-Oyashio transition region

However, they do not know whether the eddy always attracts the squid or not, and whether the eddy is always the best fishing grounds in the Kuroshio-Oyashio region or not. This is because, fishermen operate only near the eddy as long as the eddy exists.
If we get more knowledge about the squid distribution in the Kuroshio-Oyashio transition region, it is helpful to find the best fishing grounds.
We developed an individual based model for the neon flying squid to simulate its distribution in the Kuroshio-Oyashio transition region. The individual based model used an Eulerian-Lagrangian approach. The squid movements are governed by a passive transport process and the active swimming process based on a search for a local optimal habitat, which was estimated by the spatial distribution of growth rate of a bioenergetics sub-model.
In the simulation, squid do a diurnal vertical migration between surface layer and subsurface layer, which is an important ecological characteristic.
We’ll report the impacts of horizontal and vertical movements of squid on the growth, and the distribution patterns in the Kuroshio-Oyashio transition region.
