摘要

偷猎和不受管制的业余捕鱼导致了里夫纳州的贫困,在某些地方,工业上有价值的鱼类种群完全灭绝,因此,特殊商业渔业的活动确保了鱼类资源的保护。这项研究的目的是分析里弗纳州的水基金状况、这些水库鱼类资源的使用情况,特别是特别商业渔业、工业和业余捕鱼活动的结果以及水生生物资源。根据里夫纳州土地复垦和渔业局的说法,在过去的二十年里,有一种趋势,即捕捞和引入自然和人工水库的鱼的数量减少。自2010年以来,由于盈利能力低下,渔业组织的活动已经完全停止,尽管以前在大型水体上进行水生生物资源的商业捕捞,特别是在河流(Horyn, Ikva, Styr),湖泊(Nobel, Putylivske),水库(mlynivke, Khrinnytske)。如今,除了特殊的商业渔业活动外,主要的捕鱼方法是无组织的业余捕鱼。业余渔民的专门公共组织联合了8至15 000名业余渔民和运动员,进行有组织的业余捕鱼,并将鱼类资源引入该地区的水体(鲤鱼、草食性鱼类、梭子鱼和鲫鱼)。鲤鱼和鲫鱼占渔民渔获量的最大份额;梭子鱼、鲈鱼、鲢鱼、蟑螂和陆克文则不太常见。在过去十年里,里弗纳州特殊商业渔业的渔业管理状况没有改变。截至2021年,该地区只剩下11个,按租赁条款工作;还有一些私营企业,它们在全系统和非系统养殖场中种植商品鱼。与2015年相比,进入几乎所有养殖场的幼鱼数量增加了两倍,而捕鱼量略有增加。分析小型水库鱼类资源利用状况,对进一步合理开采和恢复河州小型水库鱼类资源具有重要意义

The state of use of fish resources in small reservoirs of the Rivne Oblast
Poaching and unregulated amateur fishing have led to impoverishment and, in some places, complete extermination of populations of industrially valuable fish species in Rivne Oblast, so the activities of special commercial fisheries ensure the preservation of fish resources. The purpose of the study is to analyse the state of the water fund of the Rivne Oblast, the use of fish resources of these reservoirs, in particular, the results of the activities of special commercial fisheries, industrial and amateur fishing, and aquatic bioresources. According to the State Agency of land reclamation and fisheries in Rivne Oblast, over the past twenty years, there has been a tendency to reduce the volume of fish caught and introduced into natural and artificial reservoirs. Since 2010, due to low profitability, the activities of fishing organisations have been completely stopped, although previously commercial fishing of aquatic living resources took place on large water bodies, in particular in Rivers (Horyn, Ikva, Styr), lakes (Nobel, Putylivske), reservoirs (Mlynivske, Khrinnytske). Nowadays, the main method of fishing, in addition to the activities of special commercial fisheries, is unorganised amateur fishing. Specialised public organisations of amateur fishermen unite from 8 to 15 thousand amateur fishermen and sportsmen, carry out organised amateur fishing, are engaged in the introduction of fish resources into the water bodies of the region (carp, herbivorous fish, common pike, and silver crucian carp). Carp and crucian carp make up the largest share of fishermen’s catches; pike, common perch, silver carp, roach and rudd are less common. The state of fishery management in special commercial fisheries of the Rivne Oblast has not changed over the past 10 years. As of 2021, there were only 11 of them left in the region, working on lease terms; and several private enterprises where commercial fish is grown in full-system and non-system farms. The volume of young fish entering almost all farms has tripled compared to 2015, while the volume of fish caught has slightly increased. Analysis of the state of use of fish resources in small reservoirs is necessary for further rational extraction and restoration of fish resources in small reservoirs of the Rivne Oblast
