Guest Anonymous Posted March 17, 2008 Report Share Posted March 17, 2008 Ok. Any of you with contacts I am after some proof that New Zealand has already present a Calanoid copepod "Acartia tonsa" (Dana). This is a highly beneficial marine copepod for fish breeding. If I am find this I am able to get some eggs imported from an overseas source. But ERMA (Environmental Risk Management Authority) don't have it down as a known organism, so I need to find research papers etc with it. Anyone can help? Drop me a PM or reply. Scott / Zaita.

wasp Posted March 17, 2008 Report Share Posted March 17, 2008 Hmmm.. Hate to tell you but somebody's been down this road already. But good luck, maybe there will be some more information out there. Would be great if you could do this. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 17, 2008 Report Share Posted March 17, 2008 Funny enough i was reading a paper on all Zooplankton species available in NZL waters this morning. So I sent an email to the website asking if they could give me a list of the species. Further trawling through the site I found the author of the paper works with me So I will try and catch up with her today (if she isn't at sea) to see if she has the list Will try and do the same for Phytoplankton too Quote Link to comment Share on other sites More sharing options...
wasp Posted March 17, 2008 Report Share Posted March 17, 2008 Well be great if you could keep us updated Zaita. I had a good try at this a few years ago but in the end was defeated by beaurocracy. Does your co-worker have any info on rotifers in NZ? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 17, 2008 Report Share Posted March 17, 2008 Ya know, i was just thinking about that too. I have also contacted a 2nd person at work who wrote an article about Phytoplankton in NZL. Hoping to get complete species list for that too. Rotifers should come under Zooplankton. But if I don't see any in the list I will ask around. Handy working with so many marine biologists Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 17, 2008 Report Share Posted March 17, 2008 Not found in NZL waters :'( However. After speaking to a Zooplankton specialist today (great when you can!) I have some other avenues to try out. Quote Link to comment Share on other sites More sharing options...
Scuba Sam Posted March 18, 2008 Report Share Posted March 18, 2008 I'm not too up with the play in these little creatures, but I do know that Rotifers are bred in large numbers to be used as feed in the marine farming industryin NZ. At Ruakaka, Whangarei, there is a large fish farm breeding Mussels, paua, snapper, kingfish, etc etc, and Rotifers are used as a food source. They are grown in the lab. Tanks and tanks of them. Not sure that that helps with your problem though... Quote Link to comment Share on other sites More sharing options...

Not sure that that helps with your problem though... Very valid response actually. Rotifers are available to us in the hobby, and they are very beneficial in breeding a lot of commonly bred species (e.g clowns, bangaiis, gobies). But for species that are harder to breed, or have yet to be breed Wild Zooplankton (Copepod Nauplii mostly) has been providing the most success. You can also culture them on yeast, while Rotifers require you to have quite a significant source of Phytoplankton. This is why I am keen to get a source of Zooplankton (Copepods, Isopods and Amphipods) for people to. 1) Feed Fish (like mandarins)/PipeFish/Seahorses 2) They are beneficial for a clean system as they are detrivores 3) Marine breeding Quote Link to comment Share on other sites More sharing options...
reef Posted March 18, 2008 Report Share Posted March 18, 2008 But ERMA (Environmental Risk Management Authority) don't have it down as a known organism Their are thousand of organisms ERMA does not have listed. All their records are outdated. Ask them to show you a record that oxygen is in New Zealand. At one stage they said nitrabacter was not in new zealand or any of the bacteria in filters. Been dealing with the crap for 5 years and it starts to wear you down. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 18, 2008 Report Share Posted March 18, 2008 I can only imagine After speaking with an international, and an NZL based Zooplankton specialist I have my best plan of attack. I will let details out of this a bit later once I have started working through it. Quite involved Quote Link to comment Share on other sites More sharing options...

It would be great if one could purchase zooplankton & rots to feed out. Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted March 31, 2008 Report Share Posted March 31, 2008 I'm no help, but am interested to see what you come up with! It would be great if one could purchase zooplankton & rots to feed out. I have been talking to a Copepod expert locally and have been shown where and how I can collect Tigriopus Raku for culturing. My next step is to grab some (when it stops raining) and start them off. From there I will be after a calanoid species as well. Lotsa work but its fun.
