someone mentioned to me that the NZ fur seal population has grown significantly. maybe part of the problem.
the sunday times expert says that the breeding problems of a gws is a myth. they give birth to a 1.5m long pup. after two years its 2.5m long. if it survives two years then theres no real natural enemy for it. top of the food chain.
I'm not an expert on Great Whites or the overfishing claims, but a bit of google-fu has given some food for thought.
From the wiki article on Great Whites;
So, if there are heaps of seals, why isn't there a huge population of GWS to suit?
Because GWS bread so slowly. That's is the big issue.
You would think that the population of seals would be kept in check by their predators and the available food sources.
That would make sense if shark numbers could keep up but they can't. Not all animals bread at the same rate.
Whales dying from malnutrition? Really? Are you sure? The animals they eat aren't changing, so how are they getting malnourished?
Yes im sure. Reports are popping up daily if you watch the correct sites.
Seals eat about 100kgs of fish a day? Why 100kgs? If this is/were true, and fish stocks reduced, wouldn't the seal numbers also reduce?
Why do they eat that much i don't know. I guess there hungry. Yes eventually they will run out of food. But it will take some time for that to happen. But in the mean while you have a out of balance. In SA NZ fur seals are now killing of all the penguins. In fact SA fisheries are already trying to solve that problem. Visited the back side of Rottnest lately. Seen the seen population and its growth in the last 2 years? Eagle bay was a family haunt for me for over 20 years but i will no longer even swim there.
Have you seen more seals in the water surfing?
Would be nice for a level headed fisheries fella to comment on this(you know who you are), knowing history, breeding, movement and increase in numbers etc etc.
So i have been told if GWS has a big feed very unlikely to surface again anytime soon and could be weeks for its eats again, therefore chances of killing the offender=almost immposible and they eat whatever they can.
Definitely out of control. A full on cull to push them right back to the brink of extinction would be ideal. I honestly can't see anyone missing them. It's not like people would go: "Gee remember the good old days when people got killed by sharks?" No, no one would miss them. Should be open season for every boat angler with a bounty.
Just start a rumor in Japan that ground GWS tooth powder give you a big dirk and you will see all the whalers live the whales alone and fish for shark, the powder will fetch a gigantiganonus price per gram...... problem solved![}:)]
There was a Large whale washed up at Wedge Island winter last year or was it the year before,
I know it was not removed and wobbled / broke down into the sand just north of the island.......it was posted as a topic
Factor for GWS wanting to visit the area
Listened to the fisheries head man answer sterero type questions and opinions from a female interviewer/ reporter on the 24 hour ABC channel this morning.
Bumble bumble and some more political bumble to the situation
Listen people, I can not applaud your intelligence enough. The support for a cull is fantastic! This is our opportunity. I don't believe there has been a more serious topic ever discussed on these forums. In the past we've had people writing letters to politicians to condemn / support a shark cull. This is our chance to make ourselves heard. I've written to Colin Barnett twice before but I think this time we might have more support. Make sure your voice is heard.
In my letters to the premier, I have outlined:
1) The Australian lifestyle is at risk (water sports and beach time)
2) The value of human life and how much we care about our family
Make sure you state how proud you are to be Australian and how much this beautiful country means to you. State how much our way of life should be preserved and protected and the value of our loved ones.
I'll try to get the contact details and drum up more support.
Actually. Colin Barnett said on Radio National soon after a previous attack that he was all for catching the shark and getting rid of it. He sounded very matter of fact and logical, as he often is.
Unfortunately though, not in this case. A day or two later he had completely changed his tune and was back to the old throwing tax money at the problem to study it more. Lots of "unanswered questions" and all that.
Very poor effort Col.
Largely as a consequence of that iinappropriate action we now have yet another water user turn into fish food.
