lamnidae Posted March 6, 2007 Report Share Posted March 6, 2007 I am interested on any infomation about breeding in captivity..Yes i realise they are amphidromous .Alot of my own research has discovered contrasting claims....for example a NIWA site claims that eggs have never been discovered ,but i have (from a very reliable source)been told of sucessful hatching from wild collected eggs so...confused!!!! http://www.niwascience.co.nz/rc/freshwa ... ant_kokopu any one out there been there done that i would very much appreciate any information.. ps land locked populations exist so they dont need the marine stage to repoduce..

Alan Posted March 6, 2007 Report Share Posted March 6, 2007 lamnidae, apparently they come down stream at a very high tide, spawn in the long grasses on the bank, then in a months time, the next equivalent tide pick up the fish for their marine experience then it's back home as whitebait up their original river/stream that they cam from and head upstream to continue their life. If they get passed the nets of course. The time line I do not know tho. Quote Link to comment Share on other sites More sharing options...
lamnidae Posted March 7, 2007 Author Report Share Posted March 7, 2007 yes all realised "but"gaint kokopu spawn later so the juviniles are not a usual catch in white baiters nets.Most of there catch are young inanga. This stage can be bipassed as land locked populations exist ,lake Brunner for example.Thanks for your reply. Quote Link to comment Share on other sites More sharing options...
lamnidae Posted March 7, 2007 Author Report Share Posted March 7, 2007 About half of New Zealand’s native freshwater fish species are diadromous. That is, they spend part of their life cycle at sea and migrate to fresh water for the remainder of the cycle.But some species it is possable to hatch and raise soley in fresh water... ahhh thats what i was tring to say...hahaha.

alextret Posted March 7, 2007 Report Share Posted March 7, 2007 Who would know, which of NZ species were bred in captivity? Apart from crays. Quote Link to comment Share on other sites More sharing options...
fishy_t Posted March 7, 2007 Report Share Posted March 7, 2007 Did you know that the NZ Torrent Fish's closet reletive is the Blue Cod?! (Apparently) so yeah - our freshwater fish are VERY related to our marines as well as many having a diadromous life cycle... Quote Link to comment Share on other sites More sharing options...
HandS Posted March 7, 2007 Report Share Posted March 7, 2007 The Waikato Aquarium Society visited Charles Mitchell's place some time last year(or maybe the year before) Unfortunately i missed the trip, but others enjoyed it. From memory there a quite a few native species that he breeds. http://www.rsnz.org/publish/nzjmfr/1991/22.php http://www.nzherald.co.nz/category/stor ...

fishboi Posted March 7, 2007 Report Share Posted March 7, 2007 i've had inanga breed in my ponds and indoor tanks before. didnt take any encouragement at all they just did it. was interesting to see they sort of shoot the eggs just above the water line.

fishy_t Posted March 7, 2007 Report Share Posted March 7, 2007 Cool! That would be interesting to watch... did any of the young survive? Quote Link to comment Share on other sites More sharing options...
fishboi Posted March 7, 2007 Report Share Posted March 7, 2007 Cool! That would be interesting to watch... did any of the young survive? yeah hundreds, i am sure u'll get thousands if u scrap the eggs off and give them their own tank.

Stella Posted March 25, 2007 Report Share Posted March 25, 2007 I have four giant kokopu and three bandeds from Charles Mitchell (along with inanga, crays and assorted bullies I caught myself). Really intersting guy, I hope to meet him some time. They are all this year's whitebait and starting to look really beautiful as they take on the adult form. What are you wanting to breed them in captivity for? Stella, obsessed with native fish Quote Link to comment Share on other sites More sharing options...

Ok then, how's this? ;P http://picasaweb.google.com/stellamcq/NZNativeFish (yes I have two web albums, am going to favour the picasa one and get rid of the other soon) Stella PS thanks Fishboi, I don't mind you posting the photo at all.

davidb Posted March 27, 2007 Report Share Posted March 27, 2007 hey stella I believe the unidentified bully in your photo album is the Tarndale Bully Gobiomorphus alpinus. Nice photos by the way Quote Link to comment Share on other sites More sharing options...
Stella Posted March 27, 2007 Report Share Posted March 27, 2007 Thanks DavidB, but it was caught in the manawatu (place called Horseshoe Bend near Tokomaru, no idea what the river is...), perhaps a tad far from the south island... I think it is probably a cran's or common. I lean toward cran's, but haven't really looked closely and got the books out yet. I have a couple of massey freshwater biology experty people coming over tomorrow night, hopefully will get a proper id then. (Am writing a book on keeping natives is aquaria and they are going to check out my fish and my book! exciting Thanks for the compliment on the photos. I seem to be having good luck taking photos of my fish (or maybe it is chance: take enough photos...). I even was asked for a couple of crayfish photos that were used in a display at Otari (wgtn) in the weekend! I didnt get to see it, but am kinda buzzing aobut that.

davidb Posted March 27, 2007 Report Share Posted March 27, 2007 yeah could actually be crans. haven't seen a common that light but i could be wrong... do you keep your bullys with your cray? I keep kray with kokupu and then in the other tank inaga with bullys Quote Link to comment Share on other sites More sharing options...
Stella Posted March 27, 2007 Report Share Posted March 27, 2007 yeah I have two crayfish in two tanks. My first cray was huge, well, 10cm, and became bit of a menace. I lost three of my four uplands (the only bullies I had at the time) over two months. THing is I think I lost all the males, and it was geting into spring, so I think they were nesting and easier for him to pick off. Still gutted, they were becoming rather pretty fish. Then he decided to climb out on a hot day.... Then I got a smaller cray.... am guessing 7cm at the most. And now have a teeny tiny cray, perhaps an inch long. He is so cute! They are a risk, particularly after they catch their first fish... A deep tank makes them a bit safer. Do you have pics of your tank? I always love seeing other native tanks!
