Velella project pioneers open ocean cage-farming technology
The Velella Project examined the technical viability of unanchored open-ocean fish farming by deploying a submerged net pen off Hawaii.
What you should know about aquaculture insurance
With aquaculture insurance, producers can substitute an insurance premium of a known cost for an unknown potential cost, the loss of stock.
Marine aquaculture with copper alloy nets
The use of copper alloy nets in marine aquaculture shows promise in improving biofouling resistance and net chamber volume integrity, reducing maintenance costs, and preventing fish escapement and loss due to predation.
Susan Chamberlain: 1956-2012
Of Susan Chamberlain many wonderful traits – in particular her kindness, generosity and trustworthiness – her dedication helped the Global Aquaculture Alliance endure.
Cooperation grows Australian aquaculture
Expansion of the Bribie Island Research Centre allows agencies to tackle multidisciplinary research tasks to help the Australian aquaculture industry.
Aquaculture insurance and reinsurance
As aquaculture grows, the industry will need tailored insurance solutions that address the realities of varied production methods and locations.
Mini-boutique systems designed for low-cost production efficiency
Mini-boutique systems offer a low-cost introduction to recirculating aquaculture that combines fry, fingerling and grow-out phases within a single engineering unit designed for modest stocking densities.
Artemia bioencapsulation delivers probiotics via digestive tracts of fish larvae
Research with sturgeon and carp species indicated that encapsulated artemia has high potential to carry probiotics or other beneficial microorganisms.
Low-space bioreactors remove ammonia in recirculating systems
Despite their relatively small footprint, low-space bioreactors deliver sustainable and cost-effective biological wastewater treatment, particularly in recirculating aquaculture systems, where ammonia removal is critical.
Philippines farmers apply ASA-IM high-density technology to raise marine fish
The Soy-In-Aquaculture project in the Philippines has introduced low-volume, high-density cage culture production methodology for use with high-value marine species. The technology was developed to maximize farmers’ profits, improve productivity, reduce feed-conversion ratios and limit environmental degradation.
Heat recovery: Countercurrent approach provides greater efficiency
Increasing the heat recovery efficiency of a system can save both capital and operational costs. Contain water and keep exchangers clean.
Self-regulating PHA technology offers denitrification for marine aquaculture systems
Polyhydroxyalkanotes, or PHA, biodegradable biopolymers produced from sugar fermentation, offer a potential low-maintenance denitrification method for RAS.
Cavitation, the ‘pump disease’
Cavitation occurs in a centrifugal pump when the effects of low internal water pressure lead to impeller damage. Proper design and installation of pumping systems can help.
Pilot recirculation system supports lobster-farming development in Norway
An intensive-culture recirculation system for farming European lobsters has been developed, with a pilot installation in Norway.
Offshore cages survive hurricanes
Emerging offshore aquaculture projects are proving they can endure hurricane-force winds, strong waves and high currents associated with major storms.
Nursery trial compares filtration system performance in intensive raceways
The performance of Pacific white shrimp was evaluated using three filtration systems: bead filtration, foam fractionation and pressurized sand filtration.
