项目摘要
In the present study, the changes of life-history characteristics and genefrequency in anadromous after construction of dams or weirs in the course of rivers were investigated as a model study to estimate the degree of damage to diadromous fishes according to the artificial changes of environments in rivers. In detail, the rivers where weir was constructed were selected for this research. In the rivers, the land-locked populations of white-spotted charr (Salvelinus leucomaenis) and threespine stickleback (Gasterosteus aculeatus) inhabited upstream form the weir were compared with the downstream anadromous populations of each species for life-history characters, gene frequency and genetic variability, in order to estimate the biological effects on the populations.Firstly, the fluvial populations were found to be distributed in the upstream reaches from the weir, suggesting the artificial formation of land-locked populations. The fluvial stickleback population from the NIshikitappu River showen low genetic valiability, prolongation of longevity, small body size at sexual maturity, wide reproductive season and small clutch size, compared with those of anadromous population. Similar results were obtained for white-spotted charrs in the rivers of Rebun Island.As many biological depressions were detected in the land-locked populations of two anadromous species which had been already formed after construction of weirs, it is necessary to reconsider the merits and demerits of weir construction in natural rivers from the view points of conservation of biodiversity.
本研究以人工筑坝或筑坝后溯河产卵鱼类的生活史特征和遗传多样性变化为研究对象,探讨人工改变河流环境对溯河产卵鱼类的危害程度。具体而言,本研究选取有堰建的河流作为研究对象。在河流中,生活在内陆的白斑红点鲑(Salvelinus leucomaenis)和三棘鱼(Gasterosteus aculeatus)与下游溯河产卵种群的生活史特征、基因频率和遗传变异进行了比较,以评估其对种群的生物学效应。河流种群分布在堰的上游,表明人为形成的内陆种群。与溯河产卵种群相比,西北浦河流域棘鱼种群的遗传稳定性较低,寿命较长,性成熟时个体较小,繁殖季节较宽,窝卵数较小。在礼文岛的河流中也发现了类似的结果。由于在建造堰后已经形成的两种溯河产卵物种的内陆种群中发现了许多生物洼地,因此有必要从生物多样性保护的角度重新考虑在天然河流中建造堰的利弊。
