Since September 2000, Israel has tightened restrictions on Palestinian access to the sea and to land located near the fence with Israel – Access Restricted Areas – citing security concerns. These restrictions have been enforced through the firing of live ammunition, destruction of property, arrests, and the confiscation of equipment. While sea restrictions have varied, for the most part since 2006 fishermen have been allowed to access less than one third of the fishing areas allocated to them under the Oslo Accords: six out of 20 nautical miles (NM). Fish, particularly sardines, is a major source of protein, micronutrients and essential Omega 3 fatty acids for Palestinians in Gaza and contributes to nutritional diversity The fish available in the six NM area tend to be smaller in size, limiting the type of nets that can be used, reducing the value of the catch and undermining the sustainability of marine resources. Over 35,000 Palestinians depend on this industry for their livelihoods.
