8 13 2014 Manchester Repro check

Manchester WA

Hi 60's to Mid 70s Mostly Cloudy

Performed the Anesthesia SOP with insulation and ice blocks on the treatment tub. Weather conditions allowed for the pretreatment and recovery tubs to go uncovered. All populations were brooding this week at Manchester and in almost equal numbers. Had good treatment success due to low boat traffic. Surprised at how active this site has become in supposedly the late part of the season. Definitely want to check this site again around the September full moon.

Mid 60s to high 70s sunny

Performed the anesthesia sop with insulation on treatment tub and a tarp on the Pretreatment and recovery tubs. Treatment was effective as normal so it seemed to be a fluke the last couple of weeks. Also had pretty equal brooding across all populations. Finally the northern population had the most number of brooders. I think we should check these animals again around the full moon in September to see if they are still spawning.

Shelton wa

Mid 60s to low 80s sunny

Performed the anesthesia sop with insulation on treatment tub and ice blocks on treatment and tarp cover on the Pretreatment and recovery tubs. It appears that the mussels have a significant effect on brooding as today's trays were less cover or not covered at all compared to last weeks. I saw a substantial number of brooders in the southern pop and a few in the northern and dabob pop.  We could almost assume that the other trays should be brooding in the same number as the "clean trays". We'll find out next week if the cleaning job I did last week helped out.

Manchester WA

Hi 60s to Low 80s

Performed the anesthesia SOP with insulation and ice blocks on the treatment tub and tarp on the pretreatment and recovery tubs. Forgot my work box when I was packing yesterday and had to borrow a digital thermometer, ruler, refractometer, and notebook from Doug and Andy at the NOAA facility. The thermometer read in Fahrenheit and the refractometer hadn't been calibrated recently. The readings from both seemed accurate enough though the Temp readings will need to be converted to Celsius at some point. As for spawning, the animals at Manchester seem to be increasing their spawning efforts as the next tidal cycle approaches. I had 4 brooders in the southern pop and 2 in the dabob pop, all of pretty good quality. It wouldn't surprise me with the temperatures that if the current temperatures remain through the middle of September these animals might continue spawning until they are forced to stop by temp influence.

Anacortes WA

Mid 60s to high 70s. Sunny until 2 pm then partly cloudy

Performed the anesthesia SOP with insulation on the treatment tub and ice blocks in the Treatment and recovery tubs to stabilize temperature fluctuations. Had a really poor treatment of the north sound tray and a less than great treatment of the south pop tray. Less than a third of the animals were gaping in north pop and only a little over half in the South pop were open. The Dabob tray was over 95% treated. I'm not sure we missed any brooders though as South sound only had a few and Dabob had none. I'm not sure why the animals didn't open but I assume that it might be due to the fact that they were quickly sprayed with fresh water to help knock off some of the more intense sediment deposits on them. This great to know for next time so I don't accidentally deter treatment. It seems like spawning season is winding down in Fidalgo. I'll be interested to see what the next tidal cycle does. Also yesterday I had a problem with the Hobo Shuttle. It would not read the logger pendant. I brought the logger pendant and shuttle with me to make sure neither of them was screwed up. Today I retried the pendant with the shuttle and the data offload properly. I think what happened yesterday was the shuttle go hot sitting in the sun in my tool box. The air was pretty stagnant and it got much hotter than expected. I'll double check everything on Monday to make sure the file and shuttle are in working order.

As for Pics. There were so few treated in the North pop that the tube label and calipers are on the tile with the gapers and the rest of the tiles are closed. The South pop tray is like normal with the brooders between the tube label and calipers. The Dabob tray had so many gapers that they are on all tiles but the closed guys are above the tube and calipers.

My face when treatments don't work.

Kamilche shores, wa

Hi 60s to low 80s sunny

Participants: Sean Bennett and Jake heare

Performed anesthesia sop with insulation on treatment tub and ice blocks on recovery tubs.  Found very few brooders again. I think it is a stack effect due to the unholy amounts of mussels set on the trays and oysters. Tried to clean them off but too many. Mussels probably consuming all sperm in water column.

Hi 60's to low 80's

Performed the anesthesia SOP with insulation on the treatment tub and water addition to the pretreatment and recovery tubs. Found one brooder in Southern and Dabob populations each. Also talked to Stuart at PSRF about spawning groups, he said they spawn Olys in groups of twenty.

Pics have brooders between tube label and caliper. Closed oysters on the same tile. Open oysters on the other three tiles. Some oysters on closed/brooder tiles are open and vice versa due to the fact of the guys glued to the tiles.
