CIMSEC has what I believe could be a significant proposal for how the Americas could respond to the large fleets of fishing vessels that present a threat of Illegal, Unregulated, Unreported fishing that can overwhelm the resources of the individual nations. The US Coast Guard recently assisted Ecuador in monitoring one of these fleets.
The author suggests that collective action could be taken under the Inter-American Treaty of Reciprocal Assistance (commonly known as the Rio Treaty, the Rio Pact, the Treaty of Reciprocal Assistance, or by the Spanish language acronym TIAR from Tratado Interamericano de Asistencia Recíproca), perhaps modified as necessary, but he also notes that it already includes this provision,
“…Article 11 mentions how “the High Contracting Parties recognize that, for the maintenance of peace and security in the Hemisphere, collective economic security for the development of the Member States of the Organization of American States must also be guaranteed.” It goes without saying that economic security for coastal nations includes the fishing industry.
What typically happens is that a huge international fleet will follow the fishery. Most will be in international waters, but at least some may be tempted to enter the EEZ of coastal states. This year we have seen them move from off Ecuador, past Peru, down to Chile, and they are expected to transit to waters off Argentina. The size of the fishing fleet may successively overwhelm fisheries enforcement resources of these individual countries, but a collaborative approach could allow more effective enforcement.
The author refers to the US Coast Guard Shiprider Program as a model of how cooperative enforcement might work. Enforcement operations could be conducted under the authority of a representative of the nation whose resources are under threat.
Since the threat is primarily to violations of the Exclusive Economic Zone there would be no need for these collaborating units to even enter the territorial sea of the country under threat.
If such a collaborative operation is successful in the Americas, it could serve as a model for enforcement off Africa and Southeast Asia, leading perhaps to regional Combined Maritime Security Task Forces.
