Salmon farmers limiting time at sea for biological risk mitigation
Land-based aquaculture, perhaps the ultimate environmental risk-mitigation tool, was the talk of the town at the IntraFish Seafood Investor Forum. Once scoffed at for high capital and energy requirements, RAS now has a crowded bandwagon.
Researchers overcoming learning curve for production of sea urchin seedstock
Cost-effective seedstock supply is needed for commercial production of sea urchins. Metamorphosis from free-swimming planktonic larvae to benthic grazers has presented a significant challenge.
UNC-Wilmington conducts research on black sea bass
Studies at UNC-Wilmington found that growth and survival of black sea bass larvae were improved through supplementation of DHA and ARA in live feed.
Fishmeal, fish oil replacements in sea bream, sea bass diets need nutritional compensation
Fishmeal and fish oil replacements present a challenge for the aquafeed industry. The range of alternative protein and fat sources is limited, given multiple considerations.
Current status of genome-based selection in Asian sea bass
Selection strategies to improve Asian sea bass lines, development of elite lines, practical advice and considerations for further improvements.
Cool stuff: Sea cucumbers can keep fish farms clean, research finds
University of Stirling research finds sea cucumbers can flourish by feeding on organic fish farm waste and subsequently be a high-value product.
Lumpfish production in RAS with various water treatments
This study investigated the effect of various RAS water treatment designs on water and biofilm microbiota, survival, growth and gill health of lumpfish.
Fisheries in Focus: How the mystery of the great eastern Bering Sea snow crab die-off was solved
A research team has uncovered the reason why billions of snow crabs died in the eastern Bering Sea in 2021, closing the fishery for the first time.
Probiotics improve nursery performance of juvenile sea cucumbers
While sea cucumbers are one of the most prized seafoods in China and Asia, their production suffers from suboptimal juvenile production. The use of proper feeds and overall management in the nursery can improve yield and survival.
Sea birds pose threat as vectors of penaeid shrimp pathogens
Sea birds can spread viral, bacterial, fungal and protozoan diseases to shrimp farms, so future farm designs should take their presence into account.
Commercial production of sea bream fingerlings in Spain
Sea bream fingerling producers have had to modify their facilities to grow larger animals by increasing tank volume and water flow.
Killers at sea: Harmful algal blooms and their impact on aquaculture
The causes and effects of harmful algal blooms have only been studied recently, as damage to the global aquaculture industry mounts.
Government promotes shellfish culture in Turkey
Turkey has many kilometers of coastline, but shellfish culture is developing slowly in the country. Only two bivalve farms producing mussels presently operate there. Mussel spat is collected naturally on the long line systems.
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.
Aquaculture Exchange: Peter Bridson
Peter Bridson, who steered aquaculture research for Seafood Watch and its highly influential marketplace recommendations for six years, now runs his own consultancy, Seagreen Research. He discusses global food security, certification standards and gradually changing perceptions about farmed salmon.
Aquaculture disease experts to download at GOAL 2016
At this year’s GOAL conference in Guangzhou, China, leading animal welfare and aquatic animal disease experts will share knowledge about how producers can gird their operations. EMS, EHP, streptococcosis and sea lice will be addressed, as will the latest in area management.
Polish RAS salmon farm mixes modern technology with ancient water
Jurassic Salmon, established in Poland just two years ago, is using 150-million-year-old geothermal saline waters from the “Lower Jura” era. Armed with certifications, the company is navigating an awkward growth stage.
Parasite management important to future cod aquaculture in Scotland
Parasite management is crucial for cod farming in Scotland. The main threat comes from parasites with direct or single-host life cycles.
