Growing evidence shows that conservation strategies such as fishing bans may adversely affect the livelihoods of low-income communities, which often encourages community members to fish illegally. In this study, we determined the underlying factors that influenced fishermen to engage in illegal fishing during the closed season in the largest lake of Bangladesh, Kaptai Lake. Out of 231 fishermen interviewed, 46.8% were engaged in illegal fishing during the closed season. Engagement in illegal fishing was positively related to receipt of a financial loan and negatively related to receipt of a government subsidy and secondary occupation of the fishermen. Financial gain by selling the fish was the prime motive for illegal fishing. Surprisingly, fishermen received a 36% lower price for illegally harvested fish during the closed season (mean price ± SD, BDT 95.8 ± 64.9), when compared to that during the open fishing season (BDT 151.5 ± 64.9). Mid-level actors secured 99%–154% more profit during the closed season. This study shows that multiple factors are important for the engagement of fishermen in illegal fishing, and therefore, an integrated conservation policy considering all causative factors should be employed to achieve more effective conservation in the region's inland waters.

孟加拉国卡普泰湖季节性渔业关闭期间非法捕鱼原因的案例研究

越来越多的证据表明,禁止捕鱼等保护策略可能会对低收入社区的生计产生不利影响,这往往会鼓励社区成员非法捕鱼。在这项研究中,我们确定了影响渔民在孟加拉国最大的湖泊卡普泰湖的封闭季节从事非法捕鱼的潜在因素。在接受采访的 231 名渔民中,46.8% 的渔民在休渔期从事非法捕鱼活动。从事非法捕捞与获得金融贷款呈正相关,与获得政府补贴和渔民二次职业呈负相关。卖鱼的经济利益是非法捕鱼的主要动机。令人惊讶的是,渔民在休渔期收到的非法捕捞鱼的价格降低了 36%(平均价格 ± SD,BDT 95.8 ± 64.9),与开放捕鱼季节 (BDT 151.5 ± 64.9) 相比。中层演员在休赛期获得的利润增加了 99%–154%。本研究表明,多种因素对于渔民参与非法捕鱼很重要,因此,应采用综合保护政策考虑所有成因,以实现对该地区内陆水域的更有效保护。
