متن کاملAn Individual-based Probabilistic Model for Fish Stock Simulation
We define an individual-based probabilistic model of a sole (Solea solea) behaviour. The individual model is given in terms of an Extended Probabilistic Discrete Timed Automaton (EPDTA), a new formalism that is introduced in the paper and that is shown to be interpretable as a Markov decision process. A given EPDTA model can be probabilistically model-checked by giving a suitable translation in...
متن کاملRestoring a Fish Stock: A Dynamic Bankruptcy Problem
Total Allowable Catch (TAC)-regulating schemes have been introduced in most fisheries. TAC distribution following the Proportional Rule, based on historical catches, implies that harvesters or vessel groups that have captured more in the past and contributed to overfishing are getting larger quotas than groups that have contributed less to overfishing. In contrast to this rule, a more egalitari...

Analyses of global fish stocks paint a mixed picture of success, with some holding fishery management responsible for the poor status of many stocks [1-3] or predicting widespread collapse [1, 4]. Some suggest a stable [5] or improving situation [6] in certain jurisdictions. The debate is particularly polarized in the European Union, where the Common Fisheries Policy (CFP) has been criticized f...
