F1 Broodstock spawners tagged

Objective and summary:


  • Tag all F1 broodstock scallops that were used to spawn on July 6th

  • NOTE: scallops whose gametes were kept for controlled fertilizations were given a numeric tag (small orange bee tag) - the same number as the individual recorded during spawning. Although the offpsring did not survive (Vibrio outbreak in algae culture), these tags can provide critical information if/when we reattempt with these individuals

  • Tag scheme as the following:

Treatment Spawned (Y/N) Tag color Notes
pH 8 Y blue additional numeric tag
pH 8 N blue  
pH 7.5 Y yellow additional numeric tag
pH 7.5 N yellow
