South Africa: New study proves penguins are key indicators of ocean health By News24

The three-year study looked at a colony on Robben Island during a period when the area was closed to commercial fishing and monitored the health of the birds as well as the effects on the surrounding fish populations.

The study found a direct link between the abundance of anchovy and sardine, and the penguins’ foraging behaviour and the condition of their offspring. Co-author Katta Ludynia told News24 the results clearly show the birds benefit when there’s more fish around.“If there’s a lot of fish around an island, it doesn’t mean that the birds actually have access to the fish because the fish might be taken out by the fisheries.”

Ludynia added that the study is highly relevant at the moment as the endangered African penguin continues to decline, with 2018 seeing the lowest ever recorded numbers of breeding pairs in South Africa.
