Can a diet that includes Antarctic krill improve sea bream larvae survival?
A new study suggests that sea bream larvae fed on a diet including Antarctic krill show increased survival rates and enhanced growth.
From waste to value: Upgrading marine oils from cod on-board deep-sea vessels
There is a large potential to upgrade currently wasted raw materials like cod residuals into high-quality marine oils for feed ingredients.
Company granted patent for innovative seaweed integration in commercial baking
Sea & Flour is the first company to integrate seaweed into commercial baking with a patent approved process.
Norway banned scallop harvesting in the Barents Sea. Responsible Seafood Innovation Award finalist Ava Ocean delivered a tech solution.
Ava Ocean proves scallop harvesting in the Barents Sea can be done responsibly using its selective “shellfish picker" technology.
Assessing stock enhancement for Kuruma shrimp using microsatellite markers in the South China Sea
Stock enhancement of Kuruma shrimp did not change genetic characteristics obtained by microsatellite markers in comparison to the original population.
Aquaponic system produces red drum, saltwater vegetable species
A project in Florida is studying the feasibility of a marine aquaponic system containing red drum and two native saltwater species. Water that exits the plant raceways is filtered and recirculated to the fish tanks. In tests, sea purslane grew rapidly, while saltwort took almost four months to adapt. The fish exhibited high survival and achieved a feed-conversion ratio of 1.2.
Traditional, fermented soybean meals compared in feeds for marine fish
Fishmeal sparing in aquafeed is often limited by the presence of anti-nutritional factors found in plant-derived feedstuffs. Fermentation may be a cost-effective means of addressing such factors and improving utilization of plant ingredients in feed.
Sea bass hatchery feeds artemia substitute to increase production, stability
After experiencing disappointing survival rates following traditional artemia-based rearing protocols, the French hatchery Aquastream turned to a micropellet alternative to artemia.
Algae alternatives serve in larval rearing of sea bream
Sea bream fry are produced using the greenwater technique in which microalgae are added to larval-rearing tanks during the first 20 to 30 days after hatching.
Soy products replace fishmeal, fish oil in gilthead sea bream feed study
A laboratory study indicated gilthead sea bream can be grown on feeds in which fishmeal and fish oil levels are reduced from traditional values using soy products.
By-the-numbers nutritional bioenergetics for optimal feeding
Using a series of equations, energy and protein requirements for every fish species can be calculated and adapted to changing conditions.
Land-based drip-irrigated culture of sea lettuce
A laboratory prototype methodology was developed for cost-effective, water-sparing drip-irrigation of seaweeds as a model for larger-scale land-based units.
Kelp is the climate-friendly crop that could
Kelp aquaculture is poised for growth on both U.S. coasts, but one grower network in Maine is building a brand and demand for domestic seaweed.
Maine kelp company discusses blue economy issues at World Economic Forum in Davos
Atlantic Sea Farms CEO speaks on blue foods and climate-change adaptation at World Economic Forum in Davos, Switzerland.
How data from remotely operated and autonomous underwater vehicles inform fisheries management
Management of fisheries in Alaska, the Pacific Northwest and the Gulf of Maine are starting to be informed by decades’ worth of data collection using remotely operated vehicles and autonomous underwater vehicles.
Managing fisheries for maximum nutrient yield
Maximum nutrient yield policies promote access to fish to close nutrient gaps, maximize wild fish and contribute to global food and nutrition security.
Study: Denser kelp forests are better suited to survive ocean warming
New research reveals that denser and more sheltered kelp forests can withstand serious stressors amid ocean warming.
Maine scallop farmers get the hang of Japanese technique
Thanks in part to a unique “sister state” relationship that Maine shares with Aomori Prefecture, a scallop farming technique and related equipment developed in Japan are headed to the United States. Using the equipment could save growers time and money and could signal the birth of a new industry.
