IMA is an extensive food production system - meaning low yields of shrimp despite occupying large areas. Small increases in intensification could therefore generate lots of space for mangrove restoration while increasing shrimp production. (4/10)
Large areas that were formerly mangroves are now occupied by low yielding shrimp ponds

This is mainly because pond walls isolate IMA mangroves from surrounding areas - preventing species moving into and out of the mangroves. Regular pond dredging also disturbs carbon stocks in sediments. (3/10)

We argue that IMA provide biodiversity and ecosystem functions and services that are, at best, compromised. Especially when compared to intact mangrove forests. (2/10)

New perspective paper: Is Integrated Mangrove Aquaculture (IMA) — aquaculture where mangroves are planted in or alongside shrimp ponds — good for mangrove conservation? 🧵👇 (1/10) doi.org/10.3389/ffgc.2023.10…

This focus on locally-appropriate management is crucial for balancing the needs of people and nature when implementing new global conservation targets (e.g. 30% by 2030). #30x30 (8/9)

Overall, we conclude that MPAs which allow fishing can offer more equitable pathways for biodiversity conservation — that can generate benefits for nature — than an exclusive focus on no-take MPAs. #NaturePositive #ProtectBlueNature (7/9)
Partially protected MPAs can offer effective and equitable pathways for conservation. Using partial protection widens the conservation toolbox enabling more potential for tailoring MPAs to local context. Image shows a diverse coral reef with a fisher in a boat catching a fish.

Fourth, MPAs governed by national governments can use highly tailored fisheries regulations to increase equity in access for communities – often achieved through intensive consultation or co-management with local communities. (6/9)
4. State-governed MPAs can use highly tailored fisheries restrictions to increase equity in access. Image shows a large government-owned building, and an adjacent MPA. The MPA shows zonation with some zones under customary management and other zones as no-take areas.

Third, chosen fisheries restrictions are often different when MPAs are governed by local communities compared to national governments. With many communities choosing rotating fisheries closures alongside other stronger forms of protection. (5/9)
3. Devolving resource management rights to communities influences the chosen fisheries restrictions. Image shows community group advocating for temporary fisheries closures within an MPA. The MPAs then shows a range of fisheries regulations being implemented, including a three year fisheries closure zone, a managed fisheries zone, and a no-take zone.

Second, MPAs that allowed fisheries were often used to address gaps in regional fisheries management. This is especially true in places that have histories of open access fisheries resources and limited regional management. (4/9)
2. Partially protected areas can address gaps in regional fisheries management. Image shows MPA with some — but not all — fishing gears prohibited, while the adjacent areas under regional fisheries management have fewer fishing gear restrictions.

First, we found MPAs used a wide range of approaches to manage fisheries. With 74 unique combinations of fisheries regulations across the 172 MPAs analyzed. (3/9)
1. MPAs use highly diverse approaches to regulate fisheries. Image shows: We grouped regulations based on: Where to fish (e.g., zonation), When fishing is allowed (e.g., fisheries closures), Who is allowed to fish (e.g., requiring permits), What can be caught (e.g., minimum catch size), How fish can be caught (e.g., gears restrictions), and No-take (complete prohibition on all fishing).

We analyzed fisheries regulations from 172 MPAs globally & 9 case studies. Using findings to illustrate locally-appropriate managements options that may support benefits for people and nature (2/9)
We used nine case studies to understand fisheries management, restrictions, and outcomes from a diversity of MPAs. Case studies were from: Hawaii, Belize, Madagascar, Cambodia, Australia, Indonesia, Federated States of Micronesia, Solomon Islands, and Fiji. Image shows map with case study locations identified.

New paper! We discuss how #MarineProtectedAreas (#MPAs) with diverse fishing restrictions achieve gains for nature. We recommend that countries blend locally-appropriate protection levels — from full to partial protection — to achieve conservation goals. cc to #IMPAC5 👇🧵(1/9)
