Red sea bream (Pagrus major) has been eaten in Japan for at least 5,000 years. It's featured prominently in festive occasions because the Japanese word for the species, madai, sounds like medetai, meaning auspicious or joyous. It's also an important species for Japan's commercial aquaculture sector. Its fast growth rate and ability to spawn naturally in captivity makes it economically advantageous and particularly attractive.
The Beluga sturgeon (Huso huso Linnaeus, 1758) has a decreasing population trend and is classified as critically endangered in the Black- and Azov seas, and regionally extinct in the Adriatic Sea. It is extirpated from the upper parts of almost all the European spawning rivers (e.g. Danube, Dniester, Dnieper, Don, Kuban, Terek and Volga) mainly because of overfishing and dams that block migration routes.
Sunland Hatchery is set in idyllic surroundings near Lake Cootharaba on Queensland’s Sunshine Coast. The hatchery (established in the ‘70s) spawned Australian native species and raised them for private and public stockings, and once was the country’s largest producer of Australian bass (Macquaria novemaculeata).

And now Hamlin and Ph.D. candidate LeeAnne Thayer may have gone some distance to solving the problem.
Wild Chinook salmon play a significant role in commercial, recreational and First Nations wild harvests in western Canada. These harvests, however, have been decreasing due to warming waters and shifting population ranges - both results of climate change. Since the 1990s, declines in Pacific salmon populations have led to a reduction the total value of the commercial catch in BC from $263M to $24M.
A project to address one of the key challenges faced by Scotland’s salmon farmers is underway, supported by grant funding from the Scottish Aquaculture Innovation Centre (SAIC) and UK research council BBSRC.
The island state of Tasmania is arguably Australia’s aquaculture heartland. The industry generates 30% of the nation’s total seafood production of AU$2.5billion. Of this, $25m comes from the production of edible oysters. But more significantly, Tasmania produces 95% of the Pacific Oyster (Crassostrea gigas) seedstock for the domestic industry, which is spread across New South Wales, South Australia and Tasmania. Consequently the hatchery sector has found itself playing an important role in the development of better performing and disease-resistant genotypes for a good segment of the Australian Pacific oyster sector.
A new genetic tool, designed to enable oyster farmers to select breeding stock according to both disease resistance and yield benefits, is at an advanced stage of development at the University of Edinburgh’s Roslin Institute.

Recirculating aquaculture systems (RASs) are evolving towards even higher levels of water recycling and water efficiency. This was the message presented by Dr. Dallas Weaver from Scientific Hatcheries, Huntington Beach, California, at the Recirculating Aquaculture Conference held last August in Roanoke, Virginia. Weaver and his colleagues Mark Francis and Jimmy Williamson from Aquaneering, Inc. San Diego, California; and Conal True from Universitad Autónomia de Baja California, Ensenada, Mexico, have designed, built, tested and installed a denitrification system geared to service multiple RAS systems while maintaining biosecurity between them.
You don’t have to be Einstein to realize that hatchery production underwrites aquaculture. Without reliable sources of seedstock, the supply chain of aquaculture products would have more gaps than a politician’s promise.
The snapping shrimp, aka pistol shrimp, can literally shoot its prey. Using a plunger on its enormous claw, it can shoot water at 70mph/115kpm. This water velocity creates a vacuum pressure pocket that takes gas out of solution, and expands it rapidly. The resulting explosion of gas bubble generates light, sound (210 dB), and shockwaves that can kill or stun its prey.

The Philippines’ perennial shortage of milkfish fry may find its resolution in the National Broodstock Development Program (NBDP), an initiative of the Department of Agriculture – Bureau of Fisheries and Aquatic Resources through the National Fisheries Research and Development Institute (NFRDI).“A broodstock development program is considered one of the limiting factors faced by many industry stakeholders. This may be addressed with the help of the government by establishing a broodstock development facility which will cater to the needs of interested stakeholders for their broodstock requirements by operating a breeding and hatchery facility,” Francisco Santos, OIC-Chief at the Aquaculture R&D Division of the NFRDI, told Hatchery International.“With the increased number of hatcheries operating in the locality, producing and obtaining juveniles for aquaculture use is seen to have greater feasibility and economic viability,” Santos said.NBDP, which has been approved but not yet signed, covers the stock inventory of existing breeders, hatchery facilities and manpower, selection and upgrading of broodstock, development of breeders, screening and identification of program recipients, upgrading of knowledge and skills through training and technical staff.“While milkfish is important, its production has been hindered by various problems. Among the most critical of these is the limited supply of fry,” he said.Based on 2015 figures, the milkfish requirements of the Philippines was estimated at 2.5 billion fry. Private and government hatcheries supplied only one billion. The rest were either imported, mostly from Indonesia, or were wild fry.
