8 6 2014 Manchester Repro check

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.

8 1 2014 Fidalgo Repro Check

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.

7 31 2014 oyster bay repro check

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.

7 28 2014 Temp Data Manipulation

I attempted to manipulate the temp data today. I'm running into the same sed error on the windows computers that jammed me up back in the winter. I can edit pretty much anything and produce an out file but for some reason if I try to eliminate the quotation marks using sed so that I can have clean column heading, sed will not produce an outfile or even change the file its working on. It shows the edit in the notebook but then doesn't create the actual change in the file. Does anyone know how to solve this other than bouncing back and forth between my linux computer and desktop.

See attached notebook

Performed the anesthesia sop with insulation on treatment tub and a tarp on the Pretreatment and recovery tubs. Brooding back to normal with most brooders in southern pop, and equal numbers between north and dabob. Also crab fresh cleaning salt water lines used their water for Pretreatment but not for recovery because pump was shut down.

Mid 60s to mid 70s

Participants: alicia Godersky and Jake heare

Performed anesthesia sop with insulation on treatment tub.  Found brooders in only the dabob pop. It seems that they spawn later in the season but in smaller number. We will see in the coming weeks. Also treatment was surprisingly ineffective with no discernable reason. Water was calm. Temps were stable. No movement while in tubs. Full treatment strength and time.  Hopefully it was a fluke.

Participants:  alicia Godersky and Jake heare

Performed anesthesia sop with insulation on treatment and tarp with ice blocks on recovery tubs. Very heavy mussel set on all trays and oysters. Possibly causing spawning issues. Only one population had brooders which is very different than in previous weeks. The one pop was the dabob pop with 5 brooders, one of which looked like aborted spawn.

Low 70s to Mid 80s

Participants: Alicia Godersky and Jake Heare

Performed the anesthesia SOP with insulation and ice blocks on the treatment group and tarp over the recovery and pretreatment tubs. Finally found multiple brooders in one population. If you can guess the pop, you can consider yourself an Oly Whisperer. The brooding animals were also much smaller than expected. Half were less than 20 mm which is quite odd.  Also temps fluxed on the tubs on the dock even with replacing water, the combination of sun and no breeze just baked the docks.

Low 70s to mid 80s

Performed the anesthesia sop with insulation and ice blocks on treatment and tarp cover on Pretreatment and recovery.  Found lots of brooders in southern pop and none in the other two pops. South sound oysters seem to be very attune to tidal changes. Also temps remained within range using the tarp cover. I think I should add a board or stand to keep the tarp higher over the tubs to keep it out of the water and allow for air flow to keep air temps lower. Also note to self, next week I absolutely have to refill my EtOH, 50 ml falcon tubes, and zipties. Also need a new water proof write in the rain pen as I have lost my only good one.

Klamiche shores, wa

Hi 60s to low 80s

Performed the anesthesia sop with insulation and ice blocks on treat. I also covered the Pretreatment and recovery tubs with a tarp to shade them from direct sun to help moderate the water temps. It worked well along with adding fresh seawater and leftover ice blocks, keeping the trays within 3 degrees of ambient. Also I broke the one day record for number of brooders. All pops had multiple brooders with the northern pop almost being equal to the southern pop in terms of numbers. Dabob pop also performed very well. I think this has to do with last week's neap tide and the much warmer than average air temps.
