Screening day- Arrived at 8:30am, geared up to screen through the larvae. Grace worked the screening table, Olivia managed the buckets and whatnot, I counted and re-stocked larvae, and Katie took video and images. Finished at ~2:00pm. Things went very smoothly and we got a good routine down. Here are snap-shots of the data:
After restocking, all buckets were fed 700mL algae cocktail of: 1/4 Tet, 1/4 609, 1/2 Chagra.
Images: using my phone & the new cell phone adapter, Katie imaged and observed activity. Images were taken using my phone. Here are her notes:
I fixed all screened larvae with Lugols and stored in fridge for size imaging (under the scope with the scale) at a later date.
Collected new larvae, counted, sampled, and stocked:
- HL-6 Ambient
- HL-10 Low
- K-6 Ambient
- SN-6 Low B
- NF-6 Low A
- Arrival inspection:
- All buckets very clear, likely have been without food for several hours.
- It appears the dripper was left out of NF-10 Ambient B since Saturday. Air stone was still in there; no apparent mortalities.
- Aeration was not sufficiently high on the west side of the larval table (mostly on K & HL groups).
- Temperature in the whole system has dropped to ~16degC, possibly due to it being pretty cold outside…?
- Rinsed all larval catchment buckets
- Checked on the upwelling tank outside; it is holding at 17degC
- Grace & Olivia cleaned, inspected for morts (none)
- Grace measured and adjusted flow rate to set a 1.2L/min per side
- I increased temp 1degC; temp was reading 15degC, so I set heater to 16degC
- Installed aquarium pump in header tank, fed with 490mL Reeds Shellfish Diet, and set dosing pump to 57
