Abstract

Global climate change is impacting the ecology and biogeography of marine fish populations and will continue to do so in the future. Here, I review recent records of unusual marine fish distributions from different regions of the world, and discuss the relevance of such observations to climate changes. In conclusion, I suggest that first records of fish in unusual habitats may aid as an indicator of climate changes, provided each record is critically assessed and combined with recent records of fish population parameters, population dynamics, marine habitat assessments and abiotic data such as sea bottom, middle and surface temperatures.
