Question in regards to Swim Bladders on Red Steenbras (Agulhas Banks or Transkei Coast):
Once you have caught your 1 or 2 legal limit of Red Steeenbras, do you as a conservationist stop fishing that area or continue to fish other species.
The problem I see comes while fishing for other species in the same spot is that you may inadvertently catch another Red Steenbras and how many of those fish survive due to the swim bladder sticking out the fishes mouth. In the video link provided you will notice that someone answered as follows "The few we caught were put back as this was obviously not the chosen species , we were after the silver fish and yellow tail.you cannot choose what takes the line , but at least we gave them a chance of survival"
While I accept the answer my feelings is that more experienced anglers know that for instance on the Agulhas Banks like the 45 Mile Bank, the 72 Mile Bank, the Alphard Bank and behind the 12 Mile Bank which are all known places where you can catch Red Steenbras is that this species swims near the sea bottom and are caught in and around the 30 fathom mark, which means that when the Red Steenbras is brought to the surface it will have a swollen swim bladder sometimes protruding partially or completely out its mouth.
As I have never fished along the Eastern Cape or Transkei coastline for Red Steenbras I am unaware as to what depth Red Steenbras are caught there.
In False Bay the Red Steenbras are quite small usually undersize and are caught at much shallower depths, so releasing them should not usually pose a problem.
However there is always a risk that a hook could be lodged in a place where its irretrievable or in the fishes gills, so looking at it from another perspective this species should be avoided unless you need to catch your legal quota.
Trying to avoid catching Red Steenbras would be quite difficult if you are within their known areas in my opinion as they are also known to shoal in large numbers as was the case in past years on the 45 Mile Bank.
