Sea-scale agent-based simulator of Solea solea in the adriatic sea

DISPASisanagent-basedsimulatorforfishstockassessment developed as a decision making support for the sustainable management of fishery. In this work we enlarge the underlying model of DISPAS al- lowing it to model and simulate a multi-scale scenario. We retain the cur- rently available spatial scale, able to represent a limited average region of the sea, and we introduce a new spatial macro-scale, able to represent the whole sea. At the macro-scale a single agent represents an area of five square nautical miles and manages groups of fish in different age classes. The interactions among the macro agents permit the exchange of indi- viduals of each class among neighbor areas. A case study regarding the Solea solea (Linnaeus, 1758; Soleidae) stock of the northern Adriatic Sea is used to show the intended approach, taking into account the available data, coming from fishery independent scientific surveys.
