Fish trading opportunities in the arab region

Creator:: Feidi, Izzat H.
Abstract:: All the Arab countries are producers of fish from marine, inland and aquaculture sources. Total fish production in 1994, as reported by FAO, reached 1.67 million tons. The estimated resource potential is in the range of 3-4 million tons. Trade in fish and fishery products in most countries is considerable...

Abstract:: Factors influencing the emergence of collective action are studied using survey data from individual boat owners from Barka, Masn’a and Suwaiq. Fishermen who adopt a cooperative strategy tend to be more risk averse and have high economic dependence on the common property resources. Social identity as a fisherman also appears...
