Bruny Island Oysters

8:30 am is too early to be eating oysters. Well so I thought. Sometimes you have to take a hit for the team and given the opportunity to “research” the freshest oysters possible – 8:30 doesn’t sound good, but it could be worse.

Bruny Island OystersPeople rave about Get Shucked at Bruny Island but this outing was so much better. You see, Andrea’s dad knows a guy from the pub who runs an oyster farm on Bruny Island and he was happy to take us out on the boat and show us the farm. In this case “show us out” is french for, we can tag along while Jeff gorges himself on oysters. Happy to oblige.

Oysters are the sort of thing that most people probably have no idea how they are farmed, but the process isn’t complicated and seems to be extremely gentle on the environment.

Bruny Island Oysters The farm is in a reasonably protected bay on the “open” side of Bruny island. It consists of a series of baskets suspended on frames about 30cm above the low-tide line. This is the most common way of raising oysters and provides the best way to access the oysters for grading and harvesting. The oysters aren’t attached to anything, they are just kept loose within the baskets.

Oyster Baskets

There are also a few “deep lines” which are a set of similar baskets hanging from a float out in the middle of the bay. The baskets are suspended 2m-5m below the water and the oysters grow much quicker on these lines however smaller oysters can’t be grown in them as they get washed out of the baskets and there is a lot more work involved hauling the oysters out of the water.

All the oysters start their life on the farm as small 10c piece sized oysters and are raised in small baskets standing in a protected area of the bay. Over time, these oysters get larger and every 8-12 weeks are graded and sorted into larger baskets with other oysters of similar sizes. As they get larger they get moved into a more open area of the bay. Water flow is important for the growth of the oysters and as the day progresses the swell picks up and sweeps through all of the baskets.

Bruny Island Oysters It was quite a surprise to me to learn that it takes approximately 18 months for an oyster to grow to a saleable size. There isn’t a lot of complexity in the actual growing of them but there is a constant maintenance aspect of grading, monitoring the health and making sure they aren’t growing too large – if they do the shell can be chipped back. There is a limited market for over-sized oysters (generally Asia) so keeping them to a standard size makes them much easier to sell.

While we were there the oysters across the farm had just finished spawning. This is their mating period and the oysters lose all of their fat and go from being a lively pearl colour to a pale translucent colour. During this time the product is barely sellable and for these 6 or so weeks business for an oyster farmer isn’t great. It’s definitely something to look for when purchasing them yourself.

I think I might be forever scarred from seeing Andrea’s father having to take 3 bites and a good amount of chewing on 1 particularly large, steak-sized oyster.

The majority of the oysters from this farm are shipped off weekly, unshucked to Christies seafood in the Sydney Fish Market.

Have a look at the rest of the photos. I reckon there’s some crackers.
