  Citation × Citation Citation Abstract Copy Title: Socio-economic Status of the Post-Tsunami Cage Aquaculture Farmers along Andaman Sea Coast, Thailand Author: Songrak, Apirak, Sangchan, Suchat, Tanyaros, Suwat, Anantasuk, Rattanaporn This study focused on analysis of the influences of the Post-Tsunami Rehabilitation Programs on the socio-economic status of cage aquaculture farmers along Andaman sea coast, Thailand. The study also emphasized on the enhancement of the livelihood of the farmers. Data was collected by interviewing 164 farmers, who reside in the affected-tsunami areas. The study showed that a large number of farmers were engaged in fish cage culture and small-scale fisheries as main occupations. However, the income from these economic activities could not provide enough for their basic expense, this caused by the effects of tsunami on cage culture. Therefore many farmers have to work as labors. A Post-Tsunami Rehabilitation Program since year 2005 has been trying to help and support farmers a fund to improve the materials of aquacultural cages and fishing gears. The analyses showed that the quality and quantity of equipment, seeds and feeds invested in aquaculture farms were increased (P<0.01) comparison to pre-recovery period. Importantly, the farm area, growth rate, amount of product and revenue were improved (P<0.05) during the post-tsunami rehabilitation period. Additionally, the area and quality of house, household consumption, household infrastructures, health care and education were also improved (P<0.01). The satisfaction of farmers regard to the recovery programs was quite high (WAI=3.88). However, their expectation was to have more support of fund and knowledge/technology transfer. In this study, we also found that the knowledge on fish marketing and culture techniques were poor. Lack of alternative income generation would threat on cage culture and small-scale fisheries. Henceforth, the rehabilitation program should be more paid attention on these findings. Capacity building for community strengthening was also important for sustainable post-tsunami aquaculture and small-scale fisheries in this area.

  Citation × Citation Citation Abstract Copy Title: An Examination of Productivity Potential of Aquaculture Farms in Alleviating Household Poverty: Estimation and Policy Implications from Nigeria Author: Ogundari, Kolawole This study examines income generation potential and resource- use efficiency of aquaculture farms in Nigeria. A total of 120 aquaculture farms were sampled. Using gross margin (GM) analysis, the result shows that, all the sampled farms were able to cover their total operating expenses with an average GM > 200,000 naira per annum. The assessed parameters of resource use-efficiency of the farms with stochastic frontier models (SFM) revealed that, elasticities of inputs, such as: pond size, feeds, fingerlings, and other costs were significantly different from zero. While returns to scale of 1.16 obtained from the analysis suggests that, an average farm from the study, exhibits increasing returns to scale. The estimated efficiency score revealed a significant level of inefficiency with an average technical efficiency of about 81%. This suggests that about 19% potential yield are forgone due to inefficiency from the study. The result of sources of technical efficiency shows that; extension, education, stocking density, and credit significantly influenced efficiency of the farms. Similarly, the result of the simulated marginal effects of the inefficiency variables shows that, extension has the highest marginal effects on the efficiency score follows by credit, education, and stocking density. The implications of these findings, therefore, suggest that, aquaculture will provide potential channel of income generation for households in the country considering the size of the profit obtained from the analysis. However, as matter of policy concern, extension with the highest simulated marginal effects on the efficiency score is expected to generate a large increase in the overall performance of the sector if strengthen for sustainable fish production in Nigeria.

  Citation × Citation Citation Abstract Copy Title: Aquaculture and Happiness in Vietnam - A Microeconometric Analysis Author: Hite, Diane, Nguyen, Minh Duc, Kinnucan, Henry The contribution of aquaculture development to the Vietnamese national economy and to farmers’ incomes has been documented in various government reports as well as working papers produced by development projects. However, the role of aquaculture in the life satisfaction of poor farmers has not been considered rigorously. In particular, it is very difficult to find any literature relating aquaculture adoption to job or life satisfaction of the adopters. Due to the controversial role of income in creating happiness and the increased contribution of fish production in the livelihoods of small scale farmers, there exists a question of whether income increases from adoption of aquaculture would raise happiness of farmers. This study identifies some determinants of job satisfaction and subjective well-being of small scale fish farmers in Vietnam and examines the role of earnings from fish production in generating their happiness. Cumulative logistic models with data from a 2001 survey in Southern Vietnam show that relative income, not absolute income, from aquaculture raises their job satisfaction. Higher satisfaction is also associated with involvement in extension services, a larger relative pond surface and a higher expectation level on earnings from aquaculture. The role of income per capita in job satisfaction or happiness is not confirmed. Happiness of the farmers increases with cash earnings from fish farming and income from wild fish relative to total household income.
