Rick and Michael configuring the
floating cage for life tests. |
Scallops were scrubbed clean of algal fouling,
patted dry with a paper towel, and then the shell surface
was sprayed dry with compressed air. A daub of adhesive
was placed on the dry shell surface and the plastic netting
was placed on top of the scallop and embedded in the adhesive.
Ann and Carol held the scallops and the netting in place
until the adhesive set up. The scallops were clapping, which
complicated the process. The water temp. was 25oC.
The relative humidity was almost 100 percent!
- 24 animals were attached with PSI-326 (Smart Glue) and
immersed in seawater after about 15 minutes.
- 24 amimals were attached with 3M Fastcure 08107 and
immersed in seawater after about 15 minutes.
- 36 animals were attached with Ceramicrete, and almost
all bonds failed at once when the animals were immersed.
We attribute the failure to the high humidity.
