New Knowledge

Day 31. Mussel Check at 1709

Visual tank inspections look fine for airflow but not for water clarity. Water is cloudier than yesterday and in comparison to previous checks. Mussels were still aggregated in their respective bags/ coolers. You can smell the mussels when you enter the cold room, this temperature increase may get us to 50% mortality.

  • Temperature

    • Blue= 11° C

    • Red= 22° C

  • Salinity

    • Blue= 27 psu

    • Red= 28 psu

  • Mortality

    • Blue= 0

    • Red= 7

  • Water Change

    • Partial water change for Blue and Red. Salinity recheck:

      • Blue= 25

      • Red= 25

  • With today’s mortalities, we have reached 19 out of 30 (>50%) in the elevated temperature treatment. Since we were aiming for a full 30-days, including acclimation, this is great. 22° C, despite a ramp-up is the max over time. Potentially feeding every 5 days instead of 7, and tighter salinity management with more frequent water changes may also increase resilience to the higher temp.

Old Tricks

  • The biomarker paper is my focus for editing, expanding the introduction to better scaffold the problem we are solving, and fixing the method’s subsection for analysis was my focus today. I also worked out some tentative captions for the figures, based on feedback from Alison about which viz is most effective. I am super excited about it is shaping up.
