A good study from last year by IDDRI analysed the advances on the important issue, that itself is one of the key issues in fisheries this days as more and more activities take place in ABNJ (Areas Beyond National Jurisdiction)
The study goes over the steps around a new agreement on High Seas Biodiversity since states are currently discussing the development of a new international legally binding instrument (ILBI) on the conservation and sustainable use of marine biological diversity of ABNJ.
It is a good read as it discusses valid points
Should fisheries be in or out?
It is widely acknowledged that fishing is currently the activity with the largest impact on biodiversity in ABNJ. There is a growing consensus that a new agreement should include fisheries, though it is unclear how this can be achieved. Some States continue to argue that fisheries are adequately covered by existing frameworks.
What role should have fisheries?
Fisheries are closely linked to all elements of the package of issues under discussion, particularly area-based management tools (ABMTs), including marine protected areas (MPAs) and environmental impact assessments (EIAs). Fisheries management bodies will therefore likely play a role in the implementation of various aspects of a new agreement.
The need to strengthen fisheries management
A new agreement can also complement and enhance existing fisheries management frameworks and contribute to advancing an integrated approach to ocean governance. An ILBI could improve integration and place complementary obligations on States, as well as provide overarching principles to improve coherence of the global system of ocean governance.
The topic for non lawyer like me is dry as bone, but yet I make an effort to grasp it, as law is at the basis if IUU fishing, and while it may be easier to identify IUU activities, prosecute them is a totally different topic.
