Brace yourself, KZN, you’re about to be ‘dined!

June 30, 2010

Great news! We’ve had numerous reports of solid dolphin (both common & bottlenose) and gannet feeding activity off Red Sands, Wild Coast. This is a mere 20 km south of Port Edward. Fishermen confirmed the presence of sardine in the stomachs of gamefish landed in this region. We can expect the advance shoals to reach Port Edward by the weekend, and if these shoals get squashed shorewards by warm water, then we can expect to be thrilled.

The arrival of these fish follows a period of cooling of shelf waters to within sardine’s preferred temperature range (compare the above SST image with that from the 21st June). In the image from the 26thJune, there is a clearly visible strip of 20 °C water reaching up to KZN. While these do not represent the epic conditions of 2004 (see below, but note the different temperature scales used), they should be sufficient to allow sardines to reach KZN.  Once again, the importance of temperature in regulating the movement of these fish is manifest as circumstantial evidence.

We’ll be heading back down to Port St Johns on Sunday, where we will hopefully be able to conclude our shark tagging data collection.

    No news of them yesterday, but with that westerly the fish may have been lying low. We’ll see what happens today!! Will post any news that I get.
