A couple of months ago a fishing friend and I were catching kob early morning from the reefs. About an hour after the tide turn, the kob came on the bite, but two seals also entered the scene and actively hunted in exactly the same spot we casted.
They caught two smallish kob and a skaamhaai while we were watching. During that feeding spree the kob kept on biting, albeit quite tentatively. The seals pushed them very close to the edge of the reef and we ended up casting less than twenty metres from where we stood.
