These notes describe a method of raising larvae of freshwater shrimp that have a marine (saltwater) component to their life cycle. The Shrimp reproduce in fresh water but the larva (or "Zoes") get washed out to sea, mature in seawater then find their way back into freshwater.

The adults can not tolerate seawater and the larvae will die without it.

MONICA MC·TUESDAY, AUGUST 9, 2016

• ~5 weeks from berried to hatch
• Do not need to be fed while in freshwater (at least the first 3-4 days?)
• Transfer to saltwater within 8 days of hatching (no acclimation required)
• Zoes are attracted to light
• Salinity between 30 and 35 ppt (1.022 to 1.026 sg)
• Air stone with reduced flow
• Temperature 68° F to 84° F?
• Diet (only one or two required - plankton “must have”)
• Diatoms
• Phytoplankton
• Tetraselmis
• Dunalliela Salina
• Nannochloropsis
• Rotifers? (zooplankton)
• Isochrysis sp. Tahaitian?
• Liquizell
• Golden Pearls (5-50 Microns - larger may work)
• Spirulina Powder (mixed with water)
• Mosura Shrimpton
• Light on for 16-24 hrs a day
• Morph into adults around 3-6 weeks of age
• Acclimate morphed babies (post larvae form) to fresh water within a few days over a period of 3 days, changing 50% of saltwater to fresh once a day - 4th day, move to freshwater

Side Note: Adults survive salinity up to 17-18 ppt (for hatching in brackish water) - Adults cannot survive full concentration of marine water, eggs will not hatch in saltwater
