Management
Management unit: Yes
• Management plan title: Fishery Management Plan.
• Main problems the plan intends to solve: Achieve MCS certification.
• Management actions taken: In Zanzibar - a 3 month/year (Nov-Jan) closure. Management Plan developed in cooperation with NEPAD. The Octopus fishery is under the process of certification by the MSC. The process started in 2010, and good progress has been achieved in 2015 and 2016, with the conclusion of stock assessment studies by TAFIRI. These still need to be peer reviewed. Currently, other activities are being prepared related to traceability and spatial and temporal evaluation of octopus catches.
• Year start of progress: 2012.
• Results obtained: Progress towards certification of the fisheries.
• Difficulties/constraints encountered: Catch size limit.
• Current status: The stock is declining. There is a high market demand for octopus, which drives fishers to target juveniles.
