Marine ecology

Spring algal bloom and larval fish survival

Abstract

The different factors that influence the prevalent decline in fish stocks are currently subject to urgent and intense scrutiny. Here we combine the use of remote-sensing satellite data with a long-term data set of haddock recruitment off the eastern continental shelf of Nova Scotia, Canada, to show that the survival of the larval fish depends on the timing of the local spring bloom of phytoplankton. This link has been suspected for more than 100 years, but its verification has had to wait for technology with sufficient spatial and temporal resolution.
