A nationwide recreational fishing survey in Sweden was used to estimate the benefits of recreational fishing in Sweden. The survey targeted the Swedish population and, consequently, the sample contained a large fraction of zero fishing days. To consider this, a zero-inflated Poisson model was used in the estimations. Swedes fished about 15.6 million days in 2013, of which two-thirds were spent on inland fishing, and one-third on marine and coastal fishing. Expected consumer surplus per fishing day varied with the season; SEK 193 for winter fishing, SEK 787 for summer fishing and SEK 95 for autumn fishing. Although about 70 per cent of total fishing days were spent on inland fishing, the weighted consumer surplus per fishing day in marine and coastal areas were higher. The results also demonstrated strong positive effects of increases in expected catch per day on number of fishing days demanded and consumer surplus, which have important implications for fishery policies directed at recreational fishing.

瑞典休闲垂钓的价值——基于全国调查的估计

瑞典的一项全国性休闲钓鱼调查被用来评估瑞典休闲钓鱼的好处。该调查针对瑞典人口，因此，样本包含很大一部分零捕鱼日。考虑到这一点，在估计中使用了零膨胀泊松模型。瑞典人在 2013 年的捕鱼天数约为 1560 万天，其中三分之二用于内陆捕鱼，三分之一用于海洋和沿海捕鱼。每个捕捞日的预期消费者剩余随季节变化；冬季钓鱼 193 瑞典克朗，夏季钓鱼 787 瑞典克朗，秋季钓鱼 95 瑞典克朗。尽管大约 70% 的总捕捞天数用于内陆捕捞，但海洋和沿海地区每个捕捞日的加权消费者剩余更高。
