Robbo what we're all struggling to understand is how to save our sport, and we're not finding an agreement on the best strategy.
This discussion is becoming like a table tennis game. You keep on asking me how comps might benefit the image of spearfishing, while I keep asking you how attacking competitions may benefit spearfishing. None is answering each other's question.
That's why I decided to answer my own question to make my thought clear. The answer is:
NO, attacking competitions won't help the public image of spearfishing in general. Because if we admit that comps have a potential heavy impact on fish, we admit that recreational spearfishing too has the same destructive potential, or even more.
First, you have to know this.
In my country, for recreational spearing, a single spearo has a legal total harvest limit of 5 kilograms per day. This limit doesn't apply to competitions: comps do have size and per species limits, but the harvest is virtually unlimited in terms of total weight. So, in theory, competitions are more destructive than recreational spearfishing. But this is not necessarily true.
Let's see if mathematics help a bit:
Comps: At the 2006 italian national championship for teams, sixty (60) of the most skilled spearos of the country took part to the comp. At the end of the day, the total harvest of the championship was about 35 kilograms of fish. Definitely, it wasn't a fishy day: it was not 35 kg individual, it was 35 kg TOTAL. And the average of the other comps is not much higher than this.
Recreational: put together seven recreational spearos for a group dive. On a lucky day, they all reach the harvest limit of 5 kilograms. How much is 7x5? It's 35. Now you see that just 7 recreational spearos can be, virtually but possibly and legally, as "destructive" as the whole lot of competitors of a National Championship. With a big differnce: the national chanmps are just an annual event, it occurs once in a year. While the recreational guys can dive and hunt every god blessed day: how much fish can they potentially take off the sea compared to the competition guys?
To resume: Numbers, even virtual and theoretical numbers like those I gave, could be used against us if we say that comps are heavy impact, because the same numbers show that recreational spearfishing has a bigger impact, potentially and substantially.

ALL we have to say to those ladies and gents is: NO, spearfishing has no serious impact on fish stocks in any form, competitive or recreational, and there is no ground at all to push for a ban of spearfishing AT ALL. We must be united in saying this loud.
