Australians are excited by the emergence of the spectacular and sustainable giant grouper.
World Leading Aquaculture Technology Delivers Sustainable Premium Products
The flesh of the Giant Grouper is white and flakes beautifully and the skin is wonderfully elastic. It is perfect for steaming or pan frying. The end result is easy on the eyes and incredible on the palate. It’s no wonder Australians are excited by the emergence of this spectacular and sustainable product from Tropical Finfish.
Tropical Finfish launched the Giant Grouper 6 months ago and already it has won Champion Fresh Fish at the Sydney Royal Fine Food Show and found its way into some of Australia's leading restaurants including the Noma pop-up restaurant in Sydney.
Tropical Finfish Giant Grouper is in commercial production and being sold into Australian markets.
Tropical Finfish is Australia's only producer of premium tropical finfish and has aspirations to become the world's best by supplying international markets from its Australian production facilities.
Tropical Finfish is a private group that operates world class tropical finfish production facilities in Cairns, Queensland, Australia.
Giant Grouper is protected in Australia. Years of overfishing throughout the world has reduced the breeding population forcing the International Union for Conservation of Nature (IUCN) to list the species as vulnerable.
The farm is located 6 kilometres from Cairns airport and comprises 17 production ponds, hatchery, nursery and a 1000m² processing facility. The farm has a production capacity of 350 tonnes per annum.
Each year, Tropical Finfish collects a limited number of wild specimens from North Queensland waters and carefully transports them back to the breeding facility in Cairns where they are introduced as broodstock.
The broodstock facilities are located in a specially controlled environment that allows the broodstock to spawn every month. The Grouper broodstock spawn in excess of 200 million eggs per annum.
What happens next is a delicate process. Once spawned from the broodstock, the eggs float to the top of the tank and are collected, sorted for quality, and taken to the hatchery. Twenty four hours later the little giants hatch. They remain in the larval stage for approximately 40 days and are fed a diet of mainly live food to match to their nutritional requirements. They are then transported to the nursery where they stay for approximately two to four weeks depending on the sizing requirements of the farm. Finally, the young fish are transported to the grow-out farm where they mature to market size.
The controlled hatchery environment cultivates consistent fingerling production. The larval cycle from egg to fingerling takes 35 - 45 days. Fingerlings are weaned onto pellet food around day 35 and transferred to the nursery when they reach 20mm - 25mm.
Tropical Finfish acknowledges the importance of maintaining the health of its operating environment. Accordingly, the company regularly undertakes independent NATA accredited water quality testing of discharge water to confirm that the operations have a minimal impact on the surrounding ecosystem. With commercial production of Grouper currently in its infancy, Tropical Finfish is strongly committed to delivering the substantial growth of this industry in a responsible and sustainable manner.
The specialised recirculating aquaculture system enhances fingerling growth. Fingerlings stay in the Nursery for 14 days (50mm) to 35 days (100mm) ready for transfer to grow-out facilities.
About Tropical Finfish
Tropical Finfish is a private group that operates world class tropical finfish production facilities in Cairns, Queensland, Australia. These include a state of the art breeding facility and grow-out pond farm.
Tropical Finfish is the culmination of 15 years of dedicated research under the guidance of Dr. Richard Knuckey. By combining the right species with novel feeds and innovative practices, Tropical Finfish is able to produce spectacular and sustainable products coupled with outstanding environmental performance in a scalable model.
The world class live feed facility cultures copepods, rotifers and artemia which are the high nutritional value live feed that the fish larvae consume and digest. Tropical Finfish is the only company in Australia that cultures and grows all of its live feed. The technological advances achieved within the centre are resulting in significant increases to larval survival, vigour and growth rates.
The breeding facility is capable of commercially breeding 3 species of fingerlings from the Grouper family: Queensland Groper (Giant Grouper), Gold Spotted Rock Cod (Gold Spot Grouper) and Flowery Cod (Tiger Grouper). Coral Trout is also being produced with ongoing research and development required to enhance survival rates to achieve commercial production.
With exclusive approval to collect wild broodstock, Tropical Finfish holds Australia’s first and only aquaculture permit allowing commercial captive breeding and grow-out production of market-size Giant Grouper.
Cautious fish evolve out of marine reserves Canada
New research supports the creation of more marine reserves in the world’s oceans because, the authors say, fish can evolve to be more cautious and stay away from fishing nets.
Commercial disasters declared for nine West Coast fisheries United Nations
The Commerce Secretariat determined that nine salmon and crab fisheries in Alaska, California and Washington experienced commercial failures, which will enable fishing communities to seek disaster relief assistance from Congress.
ICES identifies 'substantial' species distribution shifts Denmark
A total of 16 out of 21 species examined by experts of the Workshop on Fish Distribution Shifts in response to a request from the EC have shown changes in their distributions across the northeast Atlantic since 1985, with hake and mackerel shifting the most.
