  1. Although it is sometimes difficult for researchers to ensure that their work is used by resource managers to make informed decisions, an example where this knowledge–action gap has been breached is in research published in Aquatic Conservation: Marine and Freshwater Ecosystems (AQC) – among other journals – that has assisted fisheries managers in identifying strategies for reducing freshwater turtle bycatch in commercial hoop net fisheries in Ontario, Canada.
  2. Research published in AQC has provided evidence towards a simple and effective method for preventing turtle bycatch mortality in hoop nets, which could be adopted by the fishers. Other research published in AQC evaluated the effect of bycatch mortality on the probability of persistence of turtle populations with population viability analyses, and outlined the need to minimize bycatch mortality to prevent local extirpation. Nine other papers have been published on freshwater turtle bycatch in Ontario, furthering our knowledge on this issue including seasonality and temperature effects on catches, other net modifications, post‐release effects and assisted recovery, and the perspectives of fishers.
  3. The research results were presented to local resource managers with further discussions involving industry and stakeholders to minimize turtle bycatch mortality. Over several years, researchers have provided information to resource managers; however, when an incident of high turtle mortality caught the public eye, the research was readily available and changes in regulations were quick to occur.
  4. Reasonably good communication among researchers, resource managers, industry, stakeholders, and the broader public allowed the rapid implementation of regulations to mitigate freshwater turtle bycatch mortality and bridged the knowledge–action gap between researchers and resource managers.
  5. Both articles published in AQC had practical conservation impacts and were influential in providing local resource managers with feasible solutions, and the impetus to change regulations. These impacts extended to other jurisdictions and their monitoring programmes, where methods to reduce turtle bycatch mortality were also implemented.

淡水龟兼捕研究支持基于科学的渔业管理

  1. 尽管研究人员有时很难确保资源经理使用他们的工作来做出明智的决定,但在《水生保护:海洋和淡水生态系统》(AQC)中发表的一项研究中,这种知识-行动差距已被打破的例子。其他期刊–协助渔业经理确定了减少加拿大安大略省商业圈网捕捞中淡水龟副渔获物的策略。
  2. AQC上发表的研究提供了一种证据,证明了一种简单有效的方法可以防止网箱中乌龟兼捕的死亡率,这可供渔民采用。在AQC上发表的其他研究通过种群生存力分析评估了兼捕死亡率对乌龟种群持续存在的可能性的影响,并概述了将兼捕死亡率降至最低以防止局部灭绝的必要性。关于安大略省淡水龟副渔获物的其他9篇论文已经发表,进一步增进了我们对这一问题的认识,包括渔获物的季节和温度影响,其他净变化,释放后的影响和辅助恢复以及渔民的观点。
  3. 研究结果已提交给当地资源管理者,并与业界和利益相关者进行了进一步讨论,以最大程度地降低海龟兼捕的死亡率。几年来,研究人员向资源管理者提供了信息。但是,当海龟死​​亡率高的事件引起公众的注意时,这项研究就很容易获得,并且法规也很快发生变化。
  4. 研究人员,资源管理人员,行业,利益相关者以及广大公众之间的合理良好沟通,使法规得以快速实施,以减轻淡水龟兼捕的死亡率,并弥合了研究人​​员与资源管理人员之间的知识行动差距。
  5. 在AQC上发表的这两篇文章都对保护工作产生了实际影响,并且在为当地资源管理者提供可行的解决方案以及改变法规的动力方面具有影响力。这些影响扩展到其他辖区及其监测计划,在这些辖区还实施了降低龟副渔获物死亡率的方法。
