Phase 3 - Breakdown and Wintering Seapa Oyster Baskets: Breakdown and Wintering The method of transferring stock (approx 80k oysters)for wintering was simple and cost effective. Baskets were emptied into a Seapa basket until full at a 3 to 1 ratio thus condensing 800 baskets down to 267 baskets. At the end of a tide the empty baskets were removed from the grant and placed in storage. The full baskets remained on the grant clipped to the lines that had been lowered to the ground; ready to be removed at the first sign or possibility of ice. 25 man hours were logged in condensing 800 baskets When it came time to winter the oysters, the baskets were stacked upright in the back of pickup trucks and hauled directly to their wintering pits. Depending on the size of the pit the baskets were either stored on-end (caps upright) or on their sides. Storing the baskets with caps upright allow tier stacking by placing 1/2 plywood between each tier. Side storage also allowed stacking but caution had to be taken to avoid cap damage or duckhooks interlocking. 10 man hrs were logged for loading/unloading and storing approx 266 baskets. After removing the baskets the line system was broken down by dropping the line to the ground and removing the pvc riser posts. The line, anchors, and PVC TY's remained in the field. 4 man hours were logged for system breakdown.  Aqua Trays Breakdown and Wintering The contents of 115 the Aqua Trays (approx 35k oysters) were transferred into market bags (1/2 bu capacity). Approximately 2 market bags per tray. This was done by collecting the stock into a Seapa basket placing a market bag over the baskets opening and dumping the contents into the bag. The cover of the tray was removed and the filled bags were placed back into the trays to await removal. The covers were then taken to the offsite storage area. 12.66 man hours were logged to empty 115 trays creating 230 bags The bags were then stacked in pickup trucks and hauled to storage were they were stacked or shelved depending the storage facility. 8 man hours were logged for loading/unloading and storing 230 market bags. Breaking down the aqua tray was performed by lifting the trays, removing the caps and spacers, placing the leg components into the tray, and nest stacking the trays onto a pickup truck. 11.5 man hours were logged for system breakdown.  Envelope & Rack Breakdown and Wintering The contents of the 48 envelopes (approx 7800 oysters) were either transferred to market bags or stored "as is". The envelopes when transferred were placed into market bags kept in the field until it was time to move them off the grant. 1 man hour was logged for transferring 36 envelopes into 54 market bags 1.5 man hours were logged for loading/unloading and storing 54 market bags and 12 envelopes. Breakdown for winter consisted of bundling the 36 empty/12 full envelopes and removing the 8 empty racks to an offsite storage area. 2 man hours were logged for system breakdown |
