They have been washed up into those tidepools, they do not develop solely in those tidepools. You are better off using a plankton tow by hand in a beach or an estuary or a bay and sorting through only plankton that is swimming in the water column. If you're sorting to start a culture - you'd want adults since those are the easiest to ID. You don't need a very powerful microscope for them. Parvocalanus is 200-400 microns large as an adult.
www.littlecreatureszooplanktonandaquaculture.com.au would love to calibrate if you get some.Big hello guys and I'm needing to catch, isolate and cultivate a particular type of Copepod. The guy I need to get my hands on is Parvocalanus Crassirostris. Unfortunately here in Australia Parvocalanus Crassirostris is not available commercially which is a real pain in the butt because I know Reed Mariculture DO supply this little guy but it's not available for export to Australia. I do also know that they are quite a common Copepod free floating in ocean water not too far away so thinking wild caught might be my only way (although I did think of contacting a University to see if they possibly could assist with this/could sell me a starter culture). This also might be an interesting piece of info. for those looking at breeding because this particular strain of Copepod is the "go to" for raising larvae stage Centropyges (a dream fish for many want to be breeders!). So my question might be a little scientific based but hoping someone might have some experience with catching Copepods via ocean water sampling and then isolating particular strains they required. From what I'm researching it appears you can use different scales of micron net to isolate size wise. It also appears they may need to be isolated via microscope and safe colour injection to spot and isolate the guy needed! Any experience or tips greatly appreciated as this is all foreign to me.
*PS if you reside in the US and are interested in breeding dwarf angels this is your "go to" strain and you can start a culture a whole lot easier by purchasing a bunch of adults from Reed Mariculture! This still isn't totally straightforward though as they only prey on certain live microalgaes and if stocking density is mishandled both with food supply and the Copepods themselves you will crash the culture. Tricky little bugger!
Hey everyone! I am just posting it here as it is very relevant! If you are still after P. crassirostris - I am in Melbourne and will conduct wild collection and Isolation. I'm after another compatible hobbyist who could be a lending hand. Prior knowledge and background would be a massive plus.Big hello guys and I'm needing to catch, isolate and cultivate a particular type of Copepod.

I think you shouldn't have an issue doing it yourself. It takes me 2-3 hours to collect them and sort enough for a culture (not including driving time, but including the towing time). You don't even need a boat for this species because it is neritic. You can catch these in knee deep water.
There are actually some variation within Parvocalanus from region to region, notably there is a paper on how the ones from the Kochi coast differ to the extent that someone wrote a paper on there being a subspecies Paracalanus crassirostris cochinensis. This isn't an accepted designation, but the point is that there are unique subpopulations that could be impacted from introduced cultuviars. Practically speaking though, not sure that makes a huge deal - but you'd have to prove it to Australian biosecurity...
That is amazing! Thank you for the info! That is what I've researched as well but not sure if it'll be the case since Melbourne winter is cold...
I am not in Australia. I also do not like this forum, so if you want to keep in touch you can DM me. I hate this forum because of all the nonsense ads and them constantly asking for money whenever I login. I block this website on my email lists because its totally quackery.
I've DMed you
