Controlling shrimp populations

So, say my shrimp are soo randy they breed worse than tiny ramshorn snails. A 15 gallon tank has at least 3 batches of young from age in days to weeks, with more eggs visible on the female adults. I had 6 adults ~3 months ago and I probably have in excess of 50 shrimp in the tank now - a tad overkill.

I am debating catching as many as I can (difficult with fixed decor and delicate plants) then possibly culling the rest with a copper based med? Providing I buy sensibly next time and choose shrimp that won't breed in freshwater I negate the chances of this happening again. It is getting a wee bit silly now, my substrate is crawling with the darn things and it is not pleasant!

What type of shrimp are you talking about, surely there is a humane way to catch them? i find small cherry shrimps pretty easy to catch, then give them/sell them away here or your LFS?

If your that desperate to rid them I'll take some of your hands.
If not, prawn cocktails pretty nice.

I will likely try to use a large diameter tube to suck them up at next water change - should be sending some to someone on here but still going to end up with millions of these things forever...

I've set up a whole new tank just to get my cherries to breed, nothing yet!! Dam you!! Haha only joking. You should get some CRS, shrimp obviously like breeding in your tank then you could get a strain going to get some expensive s and ss grades ;)

Don't forget that if you cull them with a copper treatment it'll mean lots of dead bodies in the tank which will likely pollute the tank, and you know what that leads too!! -> Algae!!!

If I wasn't so far away Id have some, but I reckon postage is going to be too expensive.

Postage would be £7, but considering you'd be getting no end of shrimp it works out at about £1 a shrimp if you only take 7, half it every time you add another 7.

Cherries? Nope, no true idea to be honest. Sold as algae shrimp by my LFS.

How about setting up a net on a flat piece of gravel, put a couple of algae tablets in there, them come back in a hours time, then fish a few out, and repeat. I did this with mine, then took them to my local lfs.

Or buy a few large discus, they will soon get the taste. ;)

I wondered about some larger fish to eat them but it is only 15-gallon and I'm sticking with mini fish - catching larger ones in the future may be a pain given my decor is fixed beneath the substrate.

Net and tablet is a good idea, might try that if I can't suck them up with a tube, ta!

They are a problem as they reproduce like mad in mine, but they do keep the algae down.

On a tangent, i just found a cherry shrimp crossed with a bamboo shrimp ( i think), bright red with a darker line across his back, or that maybe just a bamboo/wood shrimp. And she was pregnent! :rolleyes:

Good luck with the net.

jokes aside......... and I'm not saying i have or necessarily that you should........ but you can eat cherry red shrimps and apparently they taste pretty good. The most authentic preparation is to steam them then serve with salad, thats how they do where they occur naturally.

Easy way to catch them put a bottle with food in with the hole so they can walk in Then just fish them out. Like a lobster pot :lol:

i generally have and sell cherry's on a regular basis, but over the holiday season i have a back log of about 200 to ship out on Monday.
will take stock and get back if any one is interested in buying some.

either way i will let you all know. if am short after mondays deliveries i can set up a waiting list for those interested, like i do which my apple snails. it would only take about 2 weeks, if that to build stock back up as they breed for me like crazy ;)
