TNC: New markets for seaweed aquaculture hold promise, but cost challenges inhibit growth
Seaweed farming can deliver economic and environmental benefits but is "significantly cost-disadvantaged," concludes a new TNC report.
Seaweeds: Top mariculture crop, ecosystem service provider
Seaweed aquaculture represents approximately half of the world mariculture production, but since seaweed farming is mostly concentrated in Asian countries, there is a lack of appreciation for this resource in the Western world.
Calcium and magnesium use in aquaculture
Aquatic plants and animals get the essential nutrients calcium and magnesium from water and food. Calcium concentrations impact the hydration and development of eggs in a hatchery, where calcium carbonate precipitation can be troublesome.
Phytoplankton in aquaculture ponds
Aquaculture ponds typically have ideal conditions for the growth of various species of phytoplankton. Green algae are considered most desirable in freshwater ponds.
Integrated multi-trophic aquaculture, part 2
Regulatory frameworks and financial incentives may be required to fully realize the benefits of integrated multi-trophic aquaculture systems.
BioMar sources new ingredients to cut carbon emissions in supply chain
BioMar is sourcing Benson Hill ingredients as part of its commitment to cut carbon emissions and build restorative soy supply chains.
Bridging the omega-3 gap with methane, microalgae
Innovation is leading to new ingredient options for renewable sources of omega-3 fatty acids. But Replicating long chain fatty acids is a tall order, Advocate contributor Lisa Duchene discovered.
Utilization of heterotrophic and autotrophic bacteria in aquaculture
An adequate understanding of autotrophic and heterotrophic bacteria is important to design and manage many aquaculture operations.
France has become innovation nation for insect production
With a thriving insect industry in France, new opportunities are emerging to advance aquaculture feeds and mitigate environmental challenges.
Stunning methods for fish
Research that has shown fish have the necessary brain structure to feel pain has displaced traditional perspectives and led to additional accounting for fish welfare in aquaculture.
Optimizing depuration of salmon in RAS
A study to evaluated operating practices and system designs that could potentially enhance depuration of off-flavors from Atlantic salmon cultured in a semi-commercial-scale freshwater recirculating aquaculture system.
Developments in closed-containment technologies for salmonids, part 2
In the second of a two-part series, Steven Summerfelt discusses various efforts to improve knowledge of closed-containment systems, innovations in fish feed and presents comprehensive concluding remarks.
Important unit processes in recirculating systems
Recirculating aquaculture systems (RAS) are increasingly used to raise fingerlings for stocking large fish in more traditional production systems. A number of unit processes are critical to the design of successful RAS systems.
Assessing groundwater quality in aquaculture
Those interested in using groundwater for aquaculture should perform a thorough chemical analysis of the water. Several problems related to groundwater use in hatcheries and holding or transport vessels can be alleviated by degassing or aeration.
New Norwegian RAS farm produces salmon smolts
The Fjordsmolt RAS farm applies a relatively simple, low-cost design to produce millions of salmon smolts per year in fiberglass tanks.
Shrimp behavior may affect culture performance at super-intensive stocking densities
Results from two studies at Oceanic Institute indicated that shrimp behavior may compromise growth at super-intensive stocking densities.
Dissolved salts in water for inland, low-salinity shrimp culture
Low-salinity shrimp culture is an important activity in Thailand. Ponds contain water of 2 to 5 ppt salinity, mixing brine solution from coastal seawater with freshwater.
Hydroponics and aquaculture: New systems for efficient food production
Archer Daniels Midland's hydroponics and aquaculture project utilizes waste heat and carbon dioxide to produce high-quality vegetables and tilapia on a year-round basis.
