What happened

A virus previously linked to devastating sardine die-offs in Australia and New Zealand has been detected in every sardine tested in the latest South African mortality event, deepening the mystery over what is killing the fish.

Why it matters

The department of forestry, fisheries and the environment (DFFE) has confirmed the presence of Pilchard Herpesvirus (PHV) in all the sardines tested so far — including fish that appeared healthy.

Common ground

But fisheries scientists are cautioning against jumping to the conclusion that the virus is responsible for the latest mass sardine deaths at several places on the Western Cape coast from Saldanha Bay to Gansbaai.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
