Blue swimming crab fisheries in Indonesia have been under high pressure for several years: quasi-open access, weak management and weak enforcement are some of the key reasons explaining the recent a stark increase in catch jeopardizing the sustainability of the resource. In January 2015, a multi stakeholder workshop was organized in Semarang to discuss potential management measures. A bioeconomic model was developed specifically for the workshop to be used during discussions, allowing direct feedback on the potential effect of various management measure mixes proposed by stakeholders. This paper presents the model developed for the workshop and how it was used to inform the discussions among stakeholders. The model describes a crab fishery in the Demak area (central Java) targeted by three gear-types (net, trap, trawl) and includes seven types of management measures that can be combined to create a pool of rules. The principal management measure mixes that were discussed during the workshop are presented and compared, notably in terms of potential short-term losses, which in the Indonesian context are strong drivers for weak compliance with new rules. Measure mixes need to be carefully phased to exert maximum effect. Since this workshop, several regulatory changes have been introduced by the Indonesian administration, notably the introduction of a minimum landing size, a ban on landing berried female and a ban on trawling. This paper also explores the potential need for further regulatory changes to reach a sustainable level of exploitation, notably the added value of a spatial approach.
