watupg Posted July 8, 2009 Report Share Posted July 8, 2009 Hi I live in Auckland CBD and want to add a koura (fresh water crayfish), some freshwater shrimps and possibly a fresh water crab to my fish tank. After doing a bit of research the best way I can see of getting them is to get out and catch them myself. Does anyone know any good spots to catch them in or just outside Auckland? And any tips on how to catch them? Thanks Quote Link to comment Share on other sites More sharing options...
Aquila Posted July 8, 2009 Report Share Posted July 8, 2009 Koura are nationally threatened...maybe you should reconsider taking them from the wild. Maybe you get get a farmed one, like this place: http://www.clearwatercrayfish.co.nz/koura.html Quote Link to comment Share on other sites More sharing options...
purplecatfish Posted July 10, 2009 Report Share Posted July 10, 2009 Catching shrimps is quite easy really. Find a beach with a small stream. Find some over hanging vegetation e.g. some grass hanging into the water. Use a net and drag it along the underside of the vegetation. If there's no shrimp then you probably wouldn't want to catch anything from that area anyway as there might be a pollution problem. Quote Link to comment Share on other sites More sharing options...

purplecatfish Posted July 10, 2009 Report Share Posted July 10, 2009 I've found them at every beach that I've tried in the Manukau Harbour Quote Link to comment Share on other sites More sharing options...
A-town... Posted July 10, 2009 Report Share Posted July 10, 2009 and they survive in freshwater or the prefer a bit of salt? Quote Link to comment Share on other sites More sharing options...
purplecatfish Posted July 10, 2009 Report Share Posted July 10, 2009 They're fine in totally fresh water. But apparently they need a bit of salt to make them breed. Having said that there used to be someone on trademe who had them breeding in her pond without salt. Quote Link to comment Share on other sites More sharing options...
watupg Posted July 17, 2009 Author Report Share Posted July 17, 2009 Thanks, I've given up on the koura idea after seeing how big they are in the shop. The ones I had seen in Lake Taupo before must have been babies as they where much smaller. If we have some good weather this weekend I'll try catching some fw shrimp and post back if I have sucess. Any idea how many would fit in a tank?? Quote Link to comment Share on other sites More sharing options...
LYNDYLOO Posted July 17, 2009 Report Share Posted July 17, 2009 Are you wanting to add these to your 22 Ltr Tank I would go there, You have to many Fish in the Tank already. Really should be cutting down on what you already have rather than adding more. Lots to learn about Keeping Fish, I've kept Fish for more than 10 years now, and still learn something new everyday. Good Luck Quote Link to comment Share on other sites More sharing options...
watupg Posted July 17, 2009 Author Report Share Posted July 17, 2009 haha thanks It was more of a scouting mission. I didn't know fw shrimp existed. After getting a fish tank it started making me curious about our natural water environment. If I can find any I'll place them back. It would not be safe to add them to my tank at the moment. Though I am considering buying a bigger tank. Most likely it will rain this weekend anyway... Quote Link to comment Share on other sites More sharing options...
