The Foundation for Food and Agriculture Research (FFAR) is a nonprofit organization established by the United States’ Congress in the 2014 Farm Bill. Remarkably for these times, there was bipartisan congressional support for the organization and the activities it supports, which include aquaculture.

As the arms race to develop more efficient and effective live feeds for hatchery applications continues Norway’s Planktonic AS has developed a unique approach which they say could be a game-changer for the industry.

Searching for better ways to preserve sperm from southern flounder, particularly wild sourced, researchers in the United States found that vitrification of flounder sperm can successfully be used to fertilize female eggs.

Larval nutrition is a complex part of the aquaculture industry, especially if one thinks of shrimp or marine fish nutrition.

A fish or shellfish hatchery uses many different fluids: Oxygen, air, fuel, water and more. Pumping or delivering these fluids through pipes, hoses, tanks and treatment systems provide a myriad of opportunity for leaks to develop and for costs to climb.

At the Conference on Recirculating Aquaculture held last August in Roanoke, Virginia, Nick King of the Fish Vet Group in Portland, Maine presented a plea for better fish health management in marine hatcheries.

A serious problem may be emerging for fish hatcheries in the United States, according to Al Barney, hatchery manager with the Nisqually Tribal Hatchery in Olympia, Washington. It’s due to increasingly restrictive regulations from the Environmental Protection Agency (EPA) concerning the chemicals that may be used to treat water for fish farming.

Sir Sandford Fleming School of Natural Resource Sciences in Lindsay, Ontario, Canada is home to the Lake Simcoe Muskellunge Restoration Project’s muskellunge hatchery. Here, nestled in rural Ontario, hatchery technician Mark Newell has pioneered the techniques to successfully raise this challenging species in a hatchery setting.

Mainstream Aquaculture has been at the forefront of innovation in the modern aquaculture industry. Focussing on barramundi (Lates calcarifer), the Australian company has become the world’s largest supplier of seedstock, and now exports to 21 countries.

The cultivation of high quality, highly priced fish such as pike-perch (Sander lucioperca) is gaining more interest. Nevertheless, the goal of sustainability is only reached if their life cycle is successfully completed under culture conditions, including reproduction and larviculture.

Any sushi lover will tell you that salmon and rice are an ideal combination.….

In a recent study Polish researchers have determined what they believe is the optimal feeding level for burbot larvae fed freshly hatched brine shrimp during three different rearing larval stages.

Unlike most recent developments in the application of advanced molecular genetics in animal breeding, Genomic Selection promises to be accessible to relatively modest breeding programmes. This is due in large part to it being less reliant on extensive infrastructure such as separate family tanks and whole-lifetime trait recording.

In the November 2014 issue of Hatchery International, contributor Erich Luening described some recent work from James Cook University in Townsville, Australia, on the shelf life of cultured micro-algal concentrates. The article also described their potential to replace live micro-algae used to enrich rotifers and other live feeds for marine fish larvae.

In Norway the majority of post-smolt Atlantic salmon (Salmo salar) are grown in sea cages, which is where the highest losses occur. According to Sara Calabrese of the University of Bergen, close to 10-15% of the fish die before reaching market size.
