Will continually update this log and adjust date to most recent date for tracking oyster morts and steps being taken to improve the oyster tank rack in FTR.

Improving the system

Notes:

  • A lot of the valves are broken, so those will need to be replaced
  • The tubing is pretty old and could use replacing

Goals:

  • Find replacement tubing and valves and get OK’d by Steven for ordering

Setting up the system.

The racks are already plumbed and have a pump system and a chiller that can be hooked up.

I set up 4 rows, 6 tanks per row. Each tank has a water input and a drain that drains into a PVC pipe that controls the outflow to the holding tank that the pump is connected to to recirculate the water through the system.

Steven and I then added 10 individuals per tank from 6 different oyster families. Family numbers: 2, 5, 6, 7, 9, and 10.

I’ll be checking daily for mortalities, logging how many are dead from which row, tank (family) number, and tossing the morts into a bucket in the cold room.

I’ll also be spot-checking temperature and salinity.
