As a Saffa, I am really concerned that no one here is talking about this and perhaps it is necessary for us to be given a much needed wake up call. The decline in coastal shark populations needs to be addressed and one way is for the dive industry here to start looking beyond narrow self-interest and become serious about it's role in the broader economy and the local communites in which they operate. The other vital point, to which you allude, is the continued use of Shark Nets - this simply has to stop. Additionally, each of us whether in South Africa or beyond can start talking about this and lobbying the appropriate structures to ensure that the decimation of our oceans is restricted and those restrictions are policed.The scarcity of Tigers on the shoal is not just as a result of illegal fishing. Increasing water temperatures seem to be linked to both the the decline in Tigers and the increase in the numbers of Black-tips. The warmer oceans are also negatively impacting on the Sardine Run, which can't help the Tigers either.I'm going down to Aliwal tomorrow (for the first time in about a year) and I'll be interested in both what I see on the shoal and the opinions of those that dive these sites regularly. Oh, BTW - I guess there are different ways to raise issues, and maybe in the culture of whichever faraway country you inhabit being rude and 'politically incorrect' achieves results, but if you do want to positively impact on the way we do things here, please learn what constitutes an acceptable way of interacting and raising issues.
