Just a quick note to let you know that there has been a FOUR MILE SPAWN in Pendrell Sound at the beginning of this week, so there should be another larger set of oysters coming if there is no significant rainfall. Thank you to Baynes Sound Oyster Co. Ltd. for the information.
If you have information that you would also like to share (or samples that you want to send), you can contact me and I’ll pass it around or reply to all in the email list.
Best and have a great weekend,

Pendrell Sound Monitoring Project – data from 12 August 2010 samples
Report date 16 August 2010
COMMERCIAL-SCALE SPAT SETTLEMENT PREDICTED FOR THIS WEEK AND NEXT WEEK!!!
(SEE DETAILS BELOW)
Note: Many thanks to Joe Sr and Joe Jr. of Baynes Sound Oysters for sending the following samples at the weekend!!
(A) Qualitative Pacific Oyster larval summary (samples were verified by Dr. Neil Bourne – thanks Neil!)
One 5-minute plankton tow at a depth of 1-2 m at each station was collected by plankton net (60µm mesh) from the Station 5 area.
| Biomass (low, medium, high) | |||
| Station | Sample 1 | Sample 2 | Sample 3 |
| D hinge | med | med | med |
| Umbone | med | med | med |
| Eyed | low | low | low |
In terms of percentages of different stages present:
5% late straight hinge stage
35% early umbo stage (10 to 14 days to settlement = approx 22nd to 26th August)
55% mid umbo stage (6 to 10 days to settlement = approx 18th to 22nd August)
5% late umbo (3 to 4 days to settlement = 15th / 16th August)
0% eyed larvae
So although there may be some settling now, the majority will settle towards the end of this week and during next week. This is also dependent upon the temperature remaining high (around 23 / 24°C) for good settlement. It is also likely that additional spawns may occur which may prolong the settlement season.
The vast majority of bivalves present in the samples were Pacific oyster larvae, with a few mussels and clams also present in small numbers.

Pendrell Sound Monitoring Project – data for 28th July 2010
