NEW optional Zapco, spat pouch revolutionizes the way spat can be outgrown reducing the need for sophisticated upwelling systems. Panelists: Oysters were stocked into 14 mm mesh uncoated Vexar bags at a density of 150 per bag. Bag coating had no effect on biofouling of bags regardless of position in cages flipped biweekly (67-69%) or triweekly (69%) (Figure 6c). Aquaculture in Canada plays a prominent role in Canada's ecological, social and economic stage. No differences in biofouling were found on bags placed in the bottom position of cages regardless of flipping regime (65-69%). We are happy to work with you to determine any other services you may need. We secure all four corners with stainless steel hog rings. Fan ratio is calculated by dividing the shell length by shell height (SL/SH) and cup ratio is calculated by dividing shell width by shell height (SW/SH). Contact us with any questions or visit our farm to see it in action. Solar energy would power an electric motor to slowly rotate columns of submerged oyster-filled cages, lifting each cage to the surface for a brief period every couple of days. However, significant differences detected in biofouling have management implications for a grower as floating bags (FB) and bags placed on the bottom level of floating cages (FC-B) had the least amount of fouling compared to bags placed on the top level of floating cages (FB-T). It also reduces the risk of over catch and fowling reducing the work load. FlipFarm When it comes to choosing the right equipment for scaling an oyster farm you can trust FlipFarm gear. Among the support Scanlan provided the Bowdoin researchers, he and his staff built twelve oyster cages and allowed them to be placed at two of his aquaculture sites. Each fall, cages and product must be lowered to the bottom for the winter season. Controlling fouling and secondary spat is as easy as flipping the cage over on the two floats (figure VI). When comparing all bags placed in the top position of cages, those in biweekly and triweekly cages had higher biofouling (69%) compared to weekly flipped cages (48%). The system we use now works very well. Legs - Riser / legs rest on the water bottom, raising the cage about 6-8 inches (hence the term off-bottom.) The trials also included evaluation of a non-toxic antifouling coating to disrupt the adhesion of fouling organisms. "They allow us to be on the water less, and we can save money on labor. Latch-Clips - Four (place one on each side of the stack and secure it with rubber cord). Thanks again! You can watch the whole video here.

Appearance of oyster meats from the floating gear types are shown in Figure 5. Although most of the culture period occurred over the cooler winter months, the triweekly flipped cages became so heavy with biofouling that they could not be flipped during the last two scheduled times. Our oysters are about 1 1/2 inches when they go into the open bay, so a half-inch square size mesh makes sense. Figure 2.
