Hi there. the local shop in kei mouth will only sell the basic squid and pilchards.. for more options like yellowtail and mackerel etc then Bilimoria in East London is you best bet. scratching around the reefs near the river mouth can be good for kob.. We go to kei mouth quite a bit during the winter for sharks.. there are two main places, duckpond and high rocks..however looking at the weather forecast I would recommend staying away from duckpond as it is an incredibly dangerous spot. High rocks is below the lighthouse towards morgan bay.
