Participatory Modeling of an Integrated Ecosystem-based Management Regime for Invasive Crabs (PICO)

The primary objective of PICO is to bring these diverse stakeholders together to co-create new knowledge through participatory bioeconomic modelling and to design integrated ecosystem-based management (EBM) regimes for Red King crab (RKC) and Snow crab (SC) in the Barents Sea. The secondary objectives of PICO are to: 1. Assess risk perceptions of RKC/SC on different marine ESs among relevant interest groups in order to capture uncertainty and parameterize bioeconomic models on management of RKC/SC; 2. Co-develop stated preference surveys for estimation of trade-offs in maintenance of sustainable populations of RKC/SC and marine ESs among general public allowing for the inclusion of non-use values in bioeconomic models; 3. Engage relevant interest groups in co-developing conceptual and applied bioeconomic models to inform EBM of RKC/SC in the Barents Sea; 4. Evaluate existing management regimes to identify types of regulatory instruments required and quantitatively estimate the desired.

PICO项目的核心目标是汇聚各类多元利益相关方，通过参与式生物经济建模协同创造新知识，并为巴伦支海的红王蟹（Red King Crab, RKC）与雪蟹（Snow Crab, SC）制定基于生态系统的综合管理（Ecosystem-based Management, EBM）机制。PICO项目的次要目标包括：1. 评估相关利益群体中红王蟹/雪蟹对不同海洋生态系统服务（Marine Ecosystem Services, ESs）的风险认知，以捕捉不确定性，并为红王蟹与雪蟹的管理相关生物经济模型设置参数；2. 协同开发陈述偏好调查（Stated Preference Surveys），用于估算普通公众在维持红王蟹、雪蟹可持续种群与海洋生态系统服务之间的权衡关系，从而将非使用价值（non-use values）纳入生物经济模型；3. 邀请相关利益群体共同构建概念性与应用型生物经济模型，为巴伦支海红王蟹与雪蟹的基于生态系统的综合管理提供决策支撑；4. 评估现有管理机制，明确所需的监管工具类型，并定量估算理想的管理方案。
