1. The price of fry between Jade Perch, Silver Perch and Sleepy Cod
Jade and silver perch fry are the same price. Sleepy cod price varies from season to season, depending success of breeding.
2. The growth rate between Jade Perch, Silver Perch and Sleepy Cod.
Sleepy cod are slower growers than the perch. Little or no, commercial figures are available for this species. They perform best in tropical conditions. In Australia winter temperatures result in very slow growth. I am told by my clients in China that they have achieved quite good growth in RAS at high temperatures.
Jade perch compered to silver perch. Jade perch grow very fast in tropical conditions. Much faster than silver perch. In a tropical climate, my best guess would be that jade perch would be about 1kg in about 10 months. Silver perch about 1kg in 12 months. Market size in Australia is generally about 800 grams.
3. The meat quality between Jade Perch, Silver Perch and Sleepy Cod.
Silver and jade perch have different fat content. Westerners prefer the silver perch because it is less fatty. Asian taste prefer jade perch because of the flavour of the fat. In fact, one of my clients in Hong Kong told me silver perch does not have enough flavour. He prefers the blend of fat and lean meat which gives it its distinctive flavour and texture. Personally I like both, but the silver perch does have a more delicate flavour. Sleepy cod are quite different to the perch. They have very little fat in their meat. The flesh is more flaky than perch. It has been compered to high end reef fish. It is generally considered to be the best freshwater table fish in Australia.
4. The market acceptance in Australia between Jade Perch, Silver Perch and Sleepy Cod.
All of these species have enjoyed market acceptance to the point that there is never enough production to meet demand. The supply has been almost exclusively absorbed by the Asian community in Sydney and Brisbane, with Melbourne only receiving a trickle of production. The production of these fish in Australia is from relatively small family business. These businesses have been steadily increasing production as their business model has allowed. No major cooperate investment has occurred. Supermarkets chains have not been able to find significant, reliable, long term supplies.
Want fish that are table size
It's no so easy to find jade perch in any retail outlet in any of the Australian cities. There is not enough production for it to be offered to the broader market. It's a long story, but essentially all these fish come from family businesses. Farms run by families. They are all making a good, secure living. It would be a big move, and risk, to jump to the "broarder market", supermarket outlets. The Asian community in our cities pretty much consume all the production. I personally have been looking into the option to have it delivered to "mum's" door. It's an obvious market, health conscious mum, or just generally health conscious people that want to eat this regularly. The best I can do at the moment is send it in a box lots, of whole, chilled jade, or silver perch, which you must collect from your local airport, and you collect it there.
