碩士 / 國立屏東科技大學 / 水產養殖系所 / 99 / The present main threat for global shrimp industry is still the hazard of viral disease. The immunity of shrimp is just with a non-specific innate immune system. It cannot protect the shrimp against the attack by most of the viruses. It always makes a serious loss of farmers whenever the virus invaded into the shrimp farm. Taiwan’s shrimp aquaculture has been fallen down dramatically by the attack of viruses since 1987, not only the production decline severely, but also the whole industry is damaged and hard to restore its brilliant times until now. Since 2000, more and more countries began buying Specific Pathogen Free (SPF) L. vannamei broodstock, which is developed by Hawaii Oceanic Institute, and develop white shrimp aquaculture industry. These SPF broodstock are highly selected from the domesticated strains and free from most of the identified viruses. Stocking SPF PL and improving the general farming technology and management systems access to a great success globally. Currently, some of the Taiwan shrimp farmers would like to buy SPF white shrimp Post-larvae (PL) and enhance their biosecurity system. They hope not only to increase their shrimp production, but also get back the reputation of Taiwan in shrimp industry. Contingent Valuation Method (CVM) is used to study the collected data. Questionnaire is designed to understand the wish of buying SPF PL and the willingness-to-pay (WTP) for the shrimp farmers. Data is analyzed by linear regression. There are 16 independent parameters in the questionnaire, which include respondents’ background and their farming experience and knowledge on the SPF white shrimp. The result showed that the average WTP for the SPF white shrimp PL by the farmers is NTD454 per 10,000 pcs. Only educational attainment of the respondents and the question on “SPF white shrimp fry is enough to solve the Taiwan shrimp industry or not?” have significant difference. For the respondents who acquire the degree of or above university (college) are willing to pay NTD321.77 per 10,000 pcs for the SPF white shrimp PL than the ones whose educational background under university (or college). In addition, the respondents who agree SPF white shrimp PL is sufficient to resolve the difficulties and problems of shrimp industry in Taiwan are willing to pay NTD354.61 per 10,000 pcs for SPF white shrimp PL than the ones who are not agree.
