摘要

到2050年,位于美国东北部的缅因州的平均气温预计将上升近1°C,这可能直接影响本地冷水鲑鱼的行为,并增加与温水小嘴鲈鱼的竞争。为了研究濒危大西洋鲑鱼幼鱼在18°C和21°C两种温度下,在存在和不存在非本地小嘴鲈鱼(Micropterus dolomieu)的情况下的摄食和激食行为,我们进行了一项微观实验。通过视觉上回顾鱼缸中鱼类竞争的镜头,我们量化了喂养和竞争相互作用。我们预测,在21°C时,鲑鱼的摄食活性将低于鲈鱼,两种物种之间的拮抗作用将随着变暖而增加。我们发现,小口鲈鱼的存在降低了鲑鱼的摄食活性,这种影响在21°C时更为强烈。我们还发现,当鲑鱼存在时,小嘴鲈鱼的攻击性在21°C时最强。最后,这两个物种的摄食活动和攻击行为都随着食物供应的变化而变化。这些发现表明,入侵的温水物种有可能与本地鲑鱼竞争资源,特别是在气候变化情景预测的更温暖的条件下。

Smallmouth bass (Micropterus dolomieu) suppress Atlantic salmon (Salmo salar) feeding activity and increase aggressive behaviours at warmer temperatures

By 2050, mean temperature in the state of Maine, located in the Northeastern USA, is expected to increase nearly 1°C, which could directly affect native coldwater salmonid behaviour and increase competition with warmwater smallmouth bass. We conducted a microcosm experiment to examine the feeding and agonistic behaviour of endangered juvenile Atlantic Salmon (Salmo salar) at two temperatures (18 and 21°C) in the presence and absence of non-native Smallmouth Bass (Micropterus dolomieu). By visually reviewing footage of fish competition in our tanks, we quantified feeding and agonistic interactions. We predicted salmon would exhibit lower feeding activity than bass at 21°C and antagonistic interactions between the two species would increase with warming. We found salmon feeding activity was reduced by smallmouth bass presence and this effect was stronger at 21°C. We also found smallmouth bass aggression was strongest at 21°C when salmon were present. Lastly, feeding activity and aggression in both species changed with food availability. These findings illustrate the potential for invasive warmwater species to outcompete native salmonids for resources, especially under the warmer conditions predicted by climate change scenarios.

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.
