Nehunter,

Based on the documented work of others, I think you could grow 15,000 or more pk shrimp each year from such a set up. If you would like my recommendations for doing so, reach out by PM and I will share what I would do for a cell that size. Stock rate, fertilization, when to harvest etc.

That's what Bob Lusk said when I asked why PK did so much better with Chara than Nitella, even though they look almost identical. He also noted that that 50 percent increase in BG biomass with PK shrimp observed by Dr Swingle was in unfed pond. Artificial feeding would likely reduce PK positive effects somewhat, though they are still a plus.

Frank, I don't know if this is the reason, but Chara hosts a symbiotic periphitic nitrogen fixing cyanobacteria. This is true of all Chara species as far as I know. This adds enough nitrogen to rice paddies to produce rice indefinitely without fertilization. I think it may at least contribute to Chara's superiority over nitella.

After reading this and a few other threads on shrimp I am interested in seeing what dumping say 4k shrimp into my new 1.5 acre pond that is full of chara. I am interested to see if that number would do anything to the chara and to see what it would do for my BG and the young bass/crappie.

I have been hesitant about putting in other fish to take care of the chara (not sure i want to add the extra biomass in something i am not going to catch) and not really into putting chemicals in. They could do nothing for the chara but it would be interesting to see if they did. Also would love to pump up my BG as well.

Sounds like a good idea. If your water has enough calcium to support chara, the shrimp should do well.

if others can tell what chemistry is necessary for shrimp to do well that would help. I've tried stocking a few times and don't seem to have survivors. I'm wondering if my 'hardness' or calcium content could be remedied if that is the missing element.

Go for it, these are great forage and if you can get them to thrive there are many of us interested in learning and trying in our puddles at home.

If RedontheHead who posted above is still here on the forum, I wonder if he still can harvest PK shrimp easily and what insight or help he could be as well!

My father in laws cow wading mud hole I mean pond has lots of ghost shrimp. They are on the edges in the torpedo grass and some floating dollar weed. The only things the Nile tilapia won’t eat. I can run the net and catch several in a few minutes. The pond has a visibility of 0” and has Nile tilapia, and bluegill also some hoplo cats and the odd walking catfish. I honestly wonder if the poor visibility and high fertility (cow manure) helps them thrive and hide.

I am going to test my water as to have as much data as i can. Then in will go the shrimp. I imagine that they will do fine with the amount of chara i have. this farm pond has not had any love until i bought it, time to see what happens.

I do, but having a tough time collecting.. been quite a challenge getting numbers up. Gets better as time goes by.

keep us posted Snipe! I'd love to be your customer and I'm starting to get a bit more vegetation so they might just survive this time. I have purchased PK shrimp on ebay but I know of no other reliable source unless other pondmeisters on this forum help each other out.

Snipe what makes it challenging to collect? Just separating them out from all the weeds that also get in the net?

Yes Snipe, please let us know when you have some numbers. I would love to try them!

I have river bulrush around 50% of my PK shrimp pond and they are way back in that stuff.
I have several patches a sago pondweed starting to grow in that pond so I think it's going to be ideal for continued production.
I'm finding that although I preach being patient, I'm somewhat impatient..

How are PK shrimp normally harvested? Can you bait them out of the weeds and into a trap?

If you can find a way to trap them, that will be very useful information for lots of PK shrimp followers. Using a sweep net among the weedy habitat is the only way that I know how to harvest them.
