Small oyster dredge for sale10/12/2023 In doing so we are doing an exaggerated simulation of the natural flow of the water, and with this process the larvae are able to disperse all throughout the tank and hopefully strike evenly across all the shell inside the tank. When we dump the larvae in we have air pumping up from the bottom to keep the larvae moving around the water column. Inside the tanks we line the bottoms with bags of shell with large silos full of shell sitting on top of them. Now where spat on shell differs from setting larvae on strike is that instead of dumping the larvae on culch in small silos we dump the buckets of larvae into large tanks. What signals us that the larvae is ready to go is when they start stringing and bunching up as opposed to just a cloud in the water. We have provided a video so you can see it yourselves. This simulates the natural flow of tides and currents in the water where oyster larvae is swept along, and while they are doing this they are being agitated signaling that it is time to release the enzymes that cause them to stick to objects and start growing their own shells. Now after they have been brought to temperature we place them in a bucket of water and stir them up. This is done to ensure the larvae is shocked by a sudden change and temperature, and it also helps the become active in the setting process much sooner. Our job here is just allowing the larvae to come to room temperature so that it is as close to the water temperature as possible. This process is not nearly as technical as the processes the hatchery employ to get the larvae. Once the larvae is bought from the Hatchery we bring it back to our nursery where we prepare the larvae to set.
