| Abstract | The study was conducted to evaluate the reasons for shrimp pond abandonment and to describe the socio-economic condition of those farmers in Pak Phanang River Basin. The study also evaluated the cost-benefits of the farmer strategies for reuse and renovating abandoned shrimp ponds and examined the institutional supp01t for farmers to reuse and renovate abandoned shrimp ponds. This study was conducted in Pak Phanang River Basin from October to November 2010 by interviewing 110 farmers, reviewing literature, and conducting field observations. The farm survey was focused on three strategies namely, Nypa planting, Nile tilapia and climbing perch culture which has been practiced by many farmers in that area. The study showed that slu·imp disease outbreak was the main reason for shrimp pond abandonment (77 households), Water zoning (49 households), environmental degradation (48 households), and low price of slu·imp product combined with high investment (25 households) were also mentioned as the other reasons for abandoning slu·imp pond. Among the tlu·ee identified strategies, Nypa planting and Nile tilapia culture strategies were in practice since 2000 while climbing perch culture strategy was introduced in the year 2002. In the study area total 121.48 hectares of abandoned slu·imp ponds are currently reused by 110 households using the tlu·ee strategies. All households culturing Nile tilapia and climbing perch have already recovered their investment while only 11 households of Nypa planting strategy group have already recovered their investment. Climbing perch culture provided very high benefit but it also required very high operation cost. Benefit-Cost Ratio values of all strategies were greater than one; it means that all strategies were acceptable. Nile tilapia culture received more institutional support than others due to the government policy. The cooperation among Nile tilapia culture households has provided more institutional supp01t to the households. This study also revealed that most of the households in the study area were faced marketing and environmental problems which are considered as the major weaknesses and threats of the strategies. |
