We have a little to do going on in the reports section, but with that debate having very few facts, I thought I best throw up a cut and paste snippet from the latest fisheries east coast fin fisheries doccument I have,
King threadfin are similar to barramundi in their
biological characteristics. They change sex from
male to female at approximately 115 cm, while
males mature at approximately 30 cm.
A 60 cm limit will protect the smaller males and
give more males an opportunity to reach the
size necessary to change sex.
A bag limit of five recognises the larger size of
king threadfin compared to blue threadfin and
also limits the catch to ensure fish are able to
change sex.
Further from memory (so don't quote me) they have a life span of app 4 years.
While I have defended peoples rights to keep fish within the legal limits on this board before I think this is a different case because this species was almost unknown in the river prior to the last few years. In fact (again from memory) I think it was young blokes like Matt that put in the hard yards and started posting about threadies that made everyone aware they were even around.
This new population of salmon is well outside its previously recognised range and to say in the last 6 months it has been getting targeted and hammered is an understatement. Common sense would suggest this population should be treated with kid gloves till such time as it is shown to be strongly established.
This population may not even be sustainable if left alone, much less without its larger specimens being removed but it would be nice to give them a chance to become strongly established if it is possible.
