Port River dolphin numbers on the rise

Findings to be published in a forthcoming report show that the number of dolphins living in Adelaide's Port River have increased threefold in the last two decades.

Dolphin shot in Australian sanctuary

There have been calls for more rangers to patrol the area around the Adelaide’s Port River dolphin sanctuary following the discovery of a shotgun pellet in a young dolphin found dead in the areas outer harbour.

Three other dolphins have been found dead in the sanctuary in recent weeks and WDC believes that the deaths could be partly due to the lack of rangers and patrols in the region, and that
