Salinity Experiment

Ryann changed the water for the 45 silos.

Checking for larvae

  • Lots: NF1,HC1
  • Some: NF4, SS4,SS1,SS2

Larval Tank Counts

  • NF_Tank2a (100,120,160) -> only swimmers of 100 size added back to NF_Tank2a with 120 and 160
  • HC_Tank1c (100,120,160) -> only swimmers of 100 size added back to HC_Tank1c with 120 and 160

Salinity Experiment

Using filtered/UV treated fresh water (not tap water) from a spigot at NOAA, I made up beakers for the salinity stress. So as to ensure all beakers got the same amount of algae (40,000 cells/mL), 160 mL of seawater in each beaker came from the same algae diet mix. The rest of the seawater required for a specific salinity came from the heated seawater line.

The temperature was 19.5degC and salinity of each replicate was checked to make sure the mixing was correct.
