Irrespective, they must be of course and unlike the majority of other factors such as habitat loss, pollutants, and nutrient run off, nets are easily addressable.
Whilst recreational impacts must also be a factor, it is quite apparent that fish populations are not depleted by recs when under an appropriate management structure of bag and size limits. This is demonstrated by the recovery of fish populations following net bans in specific regions - Lakes Macquarie and Illawarra being classic examples along with Sydney Hbr. Even when the rec take is substantially higher than that of commercial. There are good and identifiable reasons why this is so - namely because nets displace species from their spawning and feeding grounds with impacts on recruitment - an impact that recs do not have.
It may be perceived that to close areas to commercial netting will reduce the supply of locally caught seafood, but quite the opposite in actuality is what occurs. NSW, for example, saw an increase in commercial yields following implementation of 30 net free regions and the buy back of 300 inshore commercial net licences in 2001. While this may seem counterintuitive, it is actually to be expected if one understands the dynamics of fish that are targeted by commercial nets.
So, we can ponder all of the factors that Mod 2 has nominated for as long as we like and do nothing about any of them because it's too hard or expensive, or we can address our netting problem.
