Water temperature was the natural phenomenon that may be responsible for poor egg hatching. Human causes such as increased UV radiation from depleted ozone and bottom trawling disturbance were considered. Trawling disturbance had the worst effect while the other factors were questionable.

The recent developments of Atlantic cod and squid are discussed in more detail to provide a pattern that may lead to empty oceans in the future. Accounting for fish in the ocean.
