Guest Posted August 8, 2008 Report Share Posted August 8, 2008 Hi guys, I was just wondering if there are fresh water shrimp on NZ? Quote Link to comment Share on other sites More sharing options...
Stella Posted August 8, 2008 Report Share Posted August 8, 2008 yes, one species, it is very cool. Starts off as a fertile male then grows up to be a fertile female! Only shrimp species in the world that does this. There are a few discussions about them here, do an archive search. They can be kept in aquaria but in COLD water, not tropical. (people do, but it is not fair on the shrimp!) Quote Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2008 Report Share Posted August 8, 2008 I found some on "the auction site" but I don't know if I'm alowed to post the auction site on here am I? Quote Link to comment Share on other sites More sharing options...

Guest Posted August 8, 2008 Report Share Posted August 8, 2008 Whoops sorry :oops: . I've seen them in my creek (atleast I think it was them). Do you think they'd be in my creek in Lower Hutt? They were either FW shrimp or baby koura (sp). Are baby koura (those FW crayfish) small and clear? How big do the FW shrimp get? Quote Link to comment Share on other sites More sharing options...
Stella Posted August 8, 2008 Report Share Posted August 8, 2008 They could easily be there, they are more readily found near the sea (I have only seen one here in Palmy, too inland really). Baby crayfish look exactly like big crayfish, and are probably opaque. Shrimp get to about 3cm. Quote Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2008 Report Share Posted August 8, 2008 So if they're clear and small they're most probably FW shrimp. They may have got washed away in when it rained (the creek got really really fast). Quote Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2008 Report Share Posted August 8, 2008 Does anyone have any info on them or a link with info? I can't find any. I just want to know what size tank they need, any special setup, what they eat and all that. I'll go look for some tomorrow and hopefully I'll find some. I also saw the person who was selling them said they breed really easily and can lay around 1000 eggs a day (or a week I can't remember :lol: ) is this true? Do the babys (what do you call a baby shrimp) survive? Quote Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2008 Report Share Posted August 8, 2008 Or even what their real name is instead of "fresh water shrimp" :lol: :lol: Quote Link to comment Share on other sites More sharing options...
Ant N Posted August 8, 2008 Report Share Posted August 8, 2008 I had some in with White Cloud Mountain Minnows, lasted ages, came from around the Waikato. The ones with the goldfish got picked off though. Quote Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2008 Report Share Posted August 8, 2008 What sort of filter was in there? just an airstone? I could add salt to the tank if they like to have salty water. Anyone know what they're called? Are they ghost / glass shrimp? Quote Link to comment Share on other sites More sharing options...
Silvia-15 Posted August 8, 2008 Report Share Posted August 8, 2008 had heaps in a sump tank for live food :roll: very high in protein, and low in fat. caught in a little creek across the shore Quote Link to comment Share on other sites More sharing options...
Luke* Posted August 8, 2008 Report Share Posted August 8, 2008 mint a new high protein food source and if you can breed them: free. do they eat algae like amano shrimp? they are used extensively in aquascaping comps i notice Quote Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2008 Report Share Posted August 8, 2008 I read that they were glass shrimp and someone said they were Paratya curvirostris (I'm guessing this is thir scientific name). I got a pic of a Paratya curvirostris/ glass shrimp and was just wondering if this is it Quote Link to comment Share on other sites More sharing options...
Stella Posted August 8, 2008 Report Share Posted August 8, 2008 They are just freshwater shrimp, can't remember the scientific name off hand. They eat algae and biofilms. They don't lay eggs. Well, they do but they hold them under their tails till they have hatched and moulted a few times, like freshwater crayfish and crabs. I don't know if it is ok to say, I get confused with with what is ok or not with trademe, but I do not think they are actually freshwater shrimp for sale, by the tiny pic they look like mysis shrimp, hence possibly the claim that they lay 1000 eggs per day. Thus take anything said on the site they link to with a little caution if you are looking at actual freshwater shrimp. Just remembered, the freshwater shrimp are not entirely freshwater, I think they need brackish to breed. No idea how to do it or if it has been done.

Guest Posted August 8, 2008 Report Share Posted August 8, 2008 Thats sooo cool how they breed. I can add some salt to it if that would make them healthier/happier. I found a few sites about them and it only says when breeding to put a few adult females together (I thought a male would have helped them breed :lol: ). Do you know if that pics what they look like?

Stella Posted August 8, 2008 Report Share Posted August 8, 2008 Cam, that's the one! I have no idea what defines a glass shrimp. There may be a lot of things called that. Paratya curvirostris is definitely the name of the native freshwater shrimp (which is kinda technically brackish water also) Quote Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2008 Report Share Posted August 8, 2008 So how would you make the tank brackish (like how many table spoons of salt to each litre?) I think it was you who posted that they were called that in an old post Quote Link to comment Share on other sites More sharing options...
Stella Posted August 8, 2008 Report Share Posted August 8, 2008 males are smaller than females since they become females when they are older. THough quite what is happening during the crossover stage (fertile or infertile? hermaphroditic or what?) Yeah, apparently having both sexes together is useful when trying to breed things Big ones get to about 3.5cm. Quote Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2008 Report Share Posted August 8, 2008 So has anyone breed theirs. Did you have lots Silvia-15 or did they breed? Quote Link to comment Share on other sites More sharing options...
Stella Posted August 8, 2008 Report Share Posted August 8, 2008 Compare your photo with this one of mine, who was a large female with a huge horde of babies or eggs under her tail. She has more pigment because she is big. Sadly she died soon after... with her legs nibbled off! I hope it wasn't the babies.... Quote Link to comment Share on other sites More sharing options...
Silvia-15 Posted August 8, 2008 Report Share Posted August 8, 2008 nope, had no idea why, i caught heaps with eggs already attached to them. but they disappear, then they get new clusters, then they disappear also. im assuming they are tiny and get sucked through the pump into the main tank where they get devoured... but they DEFINATELY got new clusters after they went in my tank. not brackish if thats what you are wondering. but no new shrimps either, no need to feed, pickes out the little bits of stuff in the water Quote Link to comment Share on other sites More sharing options...
Cheesejawa Posted August 8, 2008 Report Share Posted August 8, 2008 Amazing that you got them to breed. They are one fine looking shrimp and the only ones we can get in NZ. Quote Link to comment Share on other sites More sharing options...
Dixon1990 Posted August 8, 2008 Report Share Posted August 8, 2008 I usually have shrimp in my Axy tank all year from waitbaiting season when we get heaps, but my Axys must of got a bit faster :lol: Quote Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2008 Report Share Posted August 8, 2008 So if I put them in a tank of their own and manage to find a group of them do you think they'll breed. I'll add salt to the tank but I don't know how much to add. Would it be a teaspoon for every litre? Thye first pic looks more like your one (thats not the glass shrimp). the 2nd ones more clear.
