And Deep Matrix Incubation Box
Experiment at Lookingglass FH
• 2010 used MAI to Incubate 30 Females
• All females spawned on the same day
• 21 females’ eggs split into 2 egg trays
• 9 females’ eggs into 1 egg tray
• MAI unit temperature set at 44 F
• MAI unit is 58”W x 82”H x 31”D
Monitoring
• Temperature inside MAI verified by independent thermometer
• No formalin, no signs of fungus
• Eggs had strong eye at 480 TU’s
• Eggs picked, eyed up at 93%
• 122,256 total eggs, 113,700 good and 8,556 dead
• Average fecundity 4,075
Deep Matrix Incubation Box• Come in 2-3 sizes or egg capacity• Put 50K-60K eggs per box• Plumbed in with flows at 5 gpm• Eggs placed on top of screen plate, 3/16 x 3/4
• Koch ring media up to 6-8 inches deep• Eggs hatch on top of screen plate, then
pass through plate down into Koch rings • Swim up fry swim out into rearing unit• Cost: $950/unit, 5 or more-$900/unit
• Traditional otolith mark
• Traditional otolith mark
• MAI otolith mark
• MAI otolith mark
Near future• Smaller MAI units with a capacity of 30-
150K eggs
• Units will be more plug and play
• Tod Jones hopes to give a presentation or paper at the next NWFCC in Vancouver o
• Brian Ashton shop remodel finished, will catch up on backlog of orders
• Considering mfg. site in Sandpoint, Id.
Summary
• New Technology• Benefit-no formalin• Benefit-water conservation• Benefit-environmentally friendly• Benefit-otolith marking• Benefit-no need for large water chillers• Benefit-space saver• Benefit-alarm system integration
Summary
• Need to have a place for eggs before they hatch
• Need to have replacement parts on hand: High pressure pump head (replacement head comes with new models) and chiller refrigerant (available at auto parts stores as R134A)
