Description:China's 13th Five-Year Plan elevated the national mandate for environmental sustainability. Chinese fisheries are characterized by full retention of high diversity catch harvested using unselective gears, creating ecological risks. Therefore, China launched pilot projects in management by Total Allowable Catch (TAC) in five coastal provinces in 2017 and 2018 to build experience with output controls. Fujian province launched an important pilot in its swimming crab fishery, the first to adopt a multispecies approach. To guide Fujian and other provinces in multispecies management, a workshop in April 2018 shared international experience. The workshop considered 13 case studies spanning a wide range of underlying scientific models and types of harvest controls. Multispecies harvest controls based on simple survey- or index-based models that aggregate trends for many species are typically operationally easier for managers and fishers. However, inadequate management can cause declines of individual species, sometimes leading to adoption of species-specific models and then species-specific harvest controls. This transition often incurs economic costs through scientific and management demands, and constraints on harvest of co-occurring species. The lessons revealed by the case studies suggest multispecies TACs might be effective in the Fujian swimming crab fishery given the modest number of species with similar and productive life history traits, and the market demand for all species. Continued experimentation with different management approaches through pilot projects can enable China to maintain progress toward sustainable fisheries goals under the 14th Five-Year Plan.
