摘要

含有大量悬沙(SS)的泄洪会导致大坝下游的总溶解气(TDG)过饱和。鱼类的游动能力可能受到TDG过饱和和SS过量的影响,但以往的研究只关注TDG和SS的单独作用,忽略了它们的共同作用。本研究以石鲤和草鱼幼鱼为研究对象,研究TDG和SS对鱼体游泳能力的交互作用。全交叉两因子设计(6个TDG水平:100%、115%、120%、125%、130%和135%;设置SS浓度0、50、100、150 mg/L,测定临界游动速度(Ucrit)和爆发游动速度(Uburst)。结果表明,两种鱼类的游泳能力(Ucrit和Uburst)均随TDG和SS浓度的增加而降低。单独暴露于TDG显著降低了两种鱼类的游泳能力,而单独暴露于SS仅降低了草鱼幼鱼的游泳能力。在TDG -过饱和水中,石鲤幼鱼的游泳能力弱于草鱼幼鱼。此外,与单独作用相比,TDG和SS的交互作用降低了石鲤和草鱼幼鱼的游泳能力,但这种降低仅对草鱼幼鱼的游泳能力有显著影响。本研究表明,含SS的TDG -过饱和水在淹水过程中可能导致鱼类通过鱼道死亡。

Interactive effects of total dissolved gas supersaturation and suspended sediment on the swimming abilities of two fish species

Discharged floods containing a large amount of suspended sediment (SS) can lead to total dissolved gas (TDG) supersaturation downstream of dams. The swimming ability of fish may be affected by TDG supersaturation and excessive SS. However, previous studies focused only on the separate effects of TDG and SS, ignoring their combined effects. In this study, juvenile rock carp and grass carp were selected to assess the interactive effects of TDG and SS on fish swimming ability. A totally crossed two-factorial design (six TDG levels: 100%, 115%, 120%, 125%, 130% and 135%; four SS concentrations: 0, 50, 100 and 150 mg/L) was set, and the critical swimming speed (Ucrit) and the burst swimming speed (Uburst) were measured. The findings indicated that the swimming abilities (Ucrit and Uburst) of both fish species decreased with increasing TDG levels and SS concentrations. Separate exposure to TDG significantly decreased the swimming abilities of the two fish species, whereas separate exposure to SS decreased only the swimming abilities of juvenile grass carp. Juvenile rock carp exhibited weaker swimming abilities than juvenile grass carp in TDG-supersaturated water. Additionally, the interaction between TDG and SS reduced the swimming abilities of juvenile rock carp and grass carp compared with a separate effect, but this reduction was significant only for the Ucrit of juvenile grass carp. This study demonstrates that TDG-supersaturated water containing SS during flooding may result in fish failure through fishways.

期刊介绍: Ecology of Freshwater Fish publishes original contributions on all aspects of fish ecology in freshwater environments, including lakes, reservoirs, rivers, and streams. Manuscripts involving ecologically-oriented studies of behavior, conservation, development, genetics, life history, physiology, and host-parasite interactions are welcomed. Studies involving population ecology and community ecology are also of interest, as are evolutionary approaches including studies of population biology, evolutionary ecology, behavioral ecology, and historical ecology. Papers addressing the life stages of anadromous and catadromous species in estuaries and inshore coastal zones are considered if they contribute to the general understanding of freshwater fish ecology. Theoretical and modeling studies are suitable if they generate testable hypotheses, as are those with implications for fisheries. Manuscripts presenting analyses of published data are considered if they produce novel conclusions or syntheses. The journal publishes articles, fresh perspectives, and reviews and, occasionally, the proceedings of conferences and symposia.
