Hello all!
I've been working for the past few months to breed peppermint shrimp and I've finally gotten some of this latest batch to almost two weeks old! I'm optimistic that they will survive to settlement as juvenile shrimp as I have had virtually no mortalities since the first couple days and they are growing very quickly and even catching and eating young/near-adult brine shrimp.
I hope to have photos soon but they are a challenge to catch holding still.
I intend to expand my aquaculture endeavors to other species, so I would like to ask what creatures everyone would really like to see aquacultured locally. I'm willing to try just about anything, although space and funding are constraints.
Currently culturing:
Copepods (harpacticoid)
Brine shrimp - Enriched with phytoplankton
Phytoplankton
Various macroalgae (Chaetomorpha, Caulerpa Racemosa)
On my radar/to-do list short term (next 6-12 months):
Calanoid pods (spp. Parvocalanus Crassiostris)(had some but temporarily dropped in favor of brine shrimp)
Urchins (Astropyga Radiata)
Mysid shrimp
Long-term ambitions:
Tridacnid Clams
Seahorses
What would you like to see cultured? Convince me of a good reason and I may well try. Especially if you would like to donate broodstock of anything (assuming I have room in my tanks).
Urchin aquaculture technique is actually quite well documented. They can be induced to spawn on demand with a mild chemical injection near their mouth. According to my research, the larvae are in some ways more hardy than peppermint shrimp zooae. ORA has already commercialized one species and they all spawn basically the same way.
Shaun: They are now 2-3 times their starting size. They have back appendages longer than their body and are starting to develop coloration in their claws. They are able to catch and eat large juvenile/adult brine shrimp.
They hatched 15 days ago, how do I know when they are about to settle?
Odd. I wonder why the heavy mortalities? Perhaps difficulty with the moult? They're 21 days old now and I still have about the same amount as I have for weeks.
Still have one that hasn't settled. I may have settled ones in the bottom of the tank that I am unaware of since the phyto murk is fairly strong (also its a 65 gallon deep hexagonal tank). I've been using a lot of gentle aeration from limewood airstones to keep the water oxygenated especially for the dark hours.
