Abstract

In recent decades, the golden jackal Canis aureus has experienced a population increase in many European countries, including Croatia. As a result, human-jackal conflicts (e.g., damage to livestock and wildlife, general nuisance in (sub)urban areas) have increased dramatically, and there is an urgent need to develop and use a range of mitigation tools that also aim to control population growth. Hunting is one of the well-known tools for population control; therefore, the aim of this study was to determine the effects of habitat type and weather conditions on jackal hunting success. From 2019 to 2023, a total of 217 jackals were culled during 106 hunting events in an approximately 10,500 ha lowland habitat along the Sava River in central Croatia. All jackals (56% males and 44% females) were culled using small calibre rifle (222 Remington) with night vision scope. Based on age structure, 16% juveniles and 84% adults were shot, and the average catch per unit effort (CPUE) was 2.0 animals/day. The best hunting success was obtained by attracting jackals with a calling method, i.e., by playing the sound of a wounded hare. Regarding the type of habitat, 56% of the culls were in cultivated, non-forested areas. It was confirmed that weather conditions, i.e., daily temperature and precipitation, influence hunting success, especially for males. Hunting success of adult males was lower on days with higher temperatures and on days with more precipitation. We can state that individual hunting with using calling method is an effective tool for successful golden jackals harvesting; moreover, jackal hunting can minimize the conflict with gamekeepers and farmers and would help to improve public perception of jackals.

影响金豺狩猎效率的因素

摘要近几十年来，包括克罗地亚在内的许多欧洲国家的金豺数量都在增加。因此，人与豺的冲突（如对牲畜和野生动物造成的损害、在（次）城市地区造成的普遍滋扰）急剧增加，迫切需要开发和使用一系列旨在控制种群增长的缓解工具。狩猎是众所周知的种群控制手段之一；因此，本研究旨在确定栖息地类型和天气条件对豺狩猎成功率的影响。从 2019 年到 2023 年，在克罗地亚中部萨瓦河沿岸约 10,500 公顷的低地栖息地进行了 106 次狩猎活动，共捕杀了 217 头豺。所有豺（56% 为雄性，44% 为雌性）均使用配备夜视镜的小口径步枪（222 雷明顿）猎杀。根据年龄结构，16% 的幼豺和 84% 的成豺被猎杀，平均单位努力捕获量（CPUE）为 2.0 头/天。狩猎成功率最高的方法是用叫声吸引豺，即播放受伤野兔的声音。在栖息地类型方面，56%的狩猎地点是在非森林种植区。研究证实，天气条件（即日气温和降水量）会影响狩猎成功率，尤其是雄性狩猎成功率。在气温较高和降水较多的日子里，成年雄性的狩猎成功率较低。我们可以说，使用呼叫法进行个体狩猎是成功捕获金豺的有效工具；此外，狩猎金豺可以最大限度地减少与猎场管理员和农民之间的冲突，并有助于改善公众对金豺的看法。

期刊介绍： European Journal of Wildlife Research focuses on all aspects of wildlife biology. Main areas are: applied wildlife ecology; diseases affecting wildlife population dynamics, conservation, economy or public health; ecotoxicology; management for conservation, hunting or pest control; population genetics; and the sustainable use of wildlife as a natural resource. Contributions to socio-cultural aspects of human-wildlife relationships and to the history and sociology of hunting will also be considered.
