Abstract: This study was conducted for 6 months from July to December, 2012 under Livestock Research Diroctate, National Center for Agricultural Research and Extension (NCARE), these governorates are Al Karak, Irbid, Ajloun and Balqa, situated in the Northern, moderate and Southern parts of Jordan to investigate constraints to successful Carp fish farming. The study area was stratified into clans with a frame survey and a random sampling method employed to select 106 fish farms with each designated farming units-from where the data were collected. Information was collected with the use of questionnaires and personal interview, transformed into data and computed with simple percentages for this research. It was discovered that despite the abundant aquaculture potentials of the study area in terms of land, local feedstuffs, good climate, lack of feasibility study on sites selection, poor fish culture management methods, poor pond construction amongst others were some of the major constraints of fish farming in the study area. However, proper feasibility study on fish farm project, site selection, knowledge of fish farm management practices, fingerling transportation from the hatchery and a running capital are some of the measures that would remove the constraints. As the results gives a summary of the constraints to successful fish farming in Jordan. Based on the outcome of the in-depth interview with key informants. Response analyses of the sub-constraints led to the identification of 6 major mutually exclusive groups of constraints: Production, environmental, socio-cultural, institutional, technological and marketing.
