Abstract |
- In the past 100 years since the birth of fisheries oceanography, research
on the early life history of fishes, particularly the larval stage, has been extensive, and
much progress has been made in identifying the mechanisms by which factors such
as feeding success, predation, or dispersal can influence larval survival. However, in
recent years, the study of fish early life history has undergone a major and, arguably,
necessary shift, resulting in a growing body of research aimed at understanding the
consequences of climate change and other anthropogenically induced stressors. Here,
we review these efforts, focusing on the ways in which fish early life stages are directly
and indirectly affected by increasing temperature; increasing CO₂ concentrations, and
ocean acidification; spatial, temporal, and magnitude changes in secondary production
and spawning; and the synergistic effects of fishing and climate change. We highlight
how these and other factors affect not only larval survivorship, but also the dispersal
of planktonic eggs and larvae, and thus the connectivity and replenishment of fish
subpopulations. While much of this work is in its infancy and many consequences are
speculative or entirely unknown, new modeling approaches are proving to be insightful
by predicting how early life stage survival may change in the future and how such
changes will impact economically and ecologically important fish populations.
