A new study details the rapid spread of the lionfish invasion in the Mediterranean Sea and its potential ecological impacts. 

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. 

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. 

After experiencing disappointing survival rates following traditional artemia-based rearing protocols, the French hatchery Aquastream turned to a micropellet alternative to artemia. 

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. 

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. 

Using a series of equations, energy and protein requirements for every fish species can be cal­culated and adapted to changing conditions. 

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 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. 

Atlantic Sea Farms CEO speaks on blue foods and climate-change adaptation at World Economic Forum in Davos, Switzerland. 

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. 

Maximum nutrient yield policies promote access to fish to close nutrient gaps, maximize wild fish and contribute to global food and nutrition security. 

New research reveals that denser and more sheltered kelp forests can withstand serious stressors amid ocean warming. 

Study shows diets with black soldier fly larvae meal did not affect general fillet parameters compared to salmon fed a commercial diet. 

Sanacore®GM, a broad range health-promoting feed additive, has been shown to reduce carbon emissions in sea bream farming by 7.5 percent. 

France Haliotis illustrates how determination can make the difference between survival and success in abalone aquaculture. 

A new study indicates deep sea phytoplankton thrive with ocean warming, raising concerns about marine ecosystems. 

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.
