Long weekend in WA last weekend. On Sunday I headed to Augusta to join my younger son and grandy who were camping there.
The Hardy Inlet is an expansive, protected area of water that's great for kids.
At the boat harbour on the coast just SW of town is an abalone farming business. It's not conventional aquaculture as such, as no caging is used.
Pinched from Wikipedia:
After trials in 2012,
[29] a commercial "sea ranch" was set up in
Flinders Bay, Western Australia to raise abalone. The ranch is based on an artificial reef made up of 5000 (As of April 2016) separate concrete units called
abitats (abalone habitats). The 900-kilogram (2,000 lb) habitats can host 400 abalone each. The reef is seeded with young abalone from an onshore hatchery.
The abalone feed on seaweed that has grown naturally on the habitats; with the ecosystem enrichment of the bay also resulting in growing numbers of dhufish, pink snapper, wrasse, Samson fish among other species.
Brad Adams, from the company, has emphasised the similarity to wild abalone and the difference from shore-based aquaculture. "We're not aquaculture, we're ranching, because once they're in the water they look after themselves.
And:
Ocean Grown Abalone
They currently have 10,000 of these 'abitats' on the 'ranch', which is in water about 15m deep in Flinders Bay. The bay abalone (sprats?) are grown in the onshore facility, then transferred into the mesh cage fixed inside the 'abitat'. They crawl out and settle on the surface of the 'abitat' to grow.
Price: $299/kg. Most product is snap-frozen, but I bought a single 90g chilled vacuum packed specimen that will be dinner tonight. $26.91.
