Análise da Preferência do Pescador Artesanal do Município de Pentecoste (CE) por Programas de Peixamento

Abstract: The continental fishing has an important role to the livelihood and income of the rural families of the Northeastern region in Brazil. Aiming to increase the catch level of the continental fishing, the National Department of Drought Works (DNOCS) has created the fish stocking program of the public dams. This research aims to reveal the fishers’ preference that live in the municipality of Pentecoste (Ceará State) towards the fish stocking program having as basis their willingness to pay (WTP) for fishing scenarios. To do that, we estimate the willingness to pay for attributes which affect the fisher’s choice for reservoir by the method of environmental valuation, called Choice Experiment. Based upon a sample of 100 fishers, the willingness to pay was estimated according to the conditional and mix logit models. The fisher’s mean WTP to fish at a stocked dam was 50,00 BRL/day that shows the increased fisher’s wellbeing due to the DNOCS’s fishing stocking program. The fisher’s mean WTP to substitute the current fishing experience (status quo) by any other proposed scenario was 89,00 BRL/day, revealing the opportunities of improving the fishing at dams of the semiarid Northeastern region.

摘要：内陆捕捞对于巴西东北部地区农村家庭的生计与收入具有重要意义。为提升内陆捕捞产量，国家抗旱工程局（National Department of Drought Works, DNOCS）牵头设立了公共水库鱼类放养项目。本研究旨在探析居住在塞阿拉州彭特科斯特（Pentecoste）市镇的渔民对于该鱼类放养项目的偏好，研究以渔民对不同捕捞场景的支付意愿（willingness to pay, WTP）为分析基础。为此，本研究采用环境价值评估方法中的选择实验法（Choice Experiment），估算影响渔民水库捕捞选择的各类属性对应的支付意愿。本研究基于100名渔民的调研样本，采用条件Logit模型与混合Logit模型估算了渔民的支付意愿。渔民在已放养鱼类的水库开展捕捞的平均支付意愿为50雷亚尔/日，这一结果表明国家抗旱工程局的鱼类放养项目有效提升了渔民的福祉水平。渔民将当前捕捞体验（现状）替换为任一其他预设场景的平均支付意愿为89雷亚尔/日，这一结果揭示了巴西东北部半干旱地区水库捕捞业的优化空间。
