Why farm salmon if you can print them?

The Fish Site — In the project Legendary Vish students from the EU-led research project Training4CRM have developed a 3D technique for printing fish. Their aim is to develop fish-like products, based on proteins from mushrooms and peas, for sushi restaurants by 2022. The Legendary Vish project is still under development and the students are currently applying for funding prior to starting Read More…

Major B.C. salmon farm tests new containment system to curb sea lice…

Coast Mountain News — A major B.C. salmon-farm operator will soon be testing a new containment system designed to prevent sea lice and algae from entering pens and hopefully reduce the chances of fish escapement. Cermaq Canada is assembling the structure, known as a semi-closed containment system (SCCS), in Port Alberni and plans to stock it with Atlantic salmon later this fall for trials Read More…

Escaped salmon unsafe for human consumption

The Fish Site — A storm sunk 16 cages at Blumar’s Caicura site last weekend and the company says it has enlisted more than 400 local fishermen to help recapture the fish, which averaged nearly 4 kg, over the next 30 days. However, Chile’s National Fisheries and Aquaculture Service (Sernapesca) has issued a warning not to eat or sell on any fish that are recaptured as they were Read More…

Why sea lice prevention is better than cure

The Fish Site — In a new article, Prevention not cure: a review of methods to avoid sea lice infestations in salmon aquaculture, researchers from the University of Melbourne, Norwegian Institute of Marine Research and Nofima argue that effectively preventing infestations before they occur causes less stress for the salmon and fewer production losses, as farmers avoid the need for delousing Read More…

Delightfully named lumpfish might boost caged salmon production

Granite Geek — Sea lice hurt Atlantic salmon, steelhead trout and other salmonids, and researchers with the New Hampshire Agricultural Experiment Station at the University of New Hampshire believe using lumpfish as cleanerfish—fish that eat parasites off other fish—may be a sustainable way to manage these pests. “Lumpfish eat parasites off salmonids farmed in cages in nearshore Read More…

She began culturing sea sponges as part of a sustainable development initiative with marinecultures.org, an ocean conservation NGO based in Zurich, Switzerland. “We’ve always lived in the lagoon with sponges – but only now have we Read More…

Start-up braced for blast-off

The Fish Site — The planned launch will take place in cooperation with research groups lead by Tokyo Institute of Technology, after Umitron was selected for the 3rd innovative satellite demonstration programme of the Japan Aerospace Exploration Agency (JAXA). High-frequency and high-resolution observations of plankton and nutrient levels will be acquired to support fish, shellfish and Read More…

Fish farming alters microbial communities, and reduces nitrate levels…

EurekAlert! — Small-scale water bodies with areas less than 0.1 km2, such as natural ponds, constitute the quantitative bulk of global inland water bodies, and are very susceptible to human disturbances and environmental change. In agricultural regions of China, water quality in ponds has deteriorated by high loads of nitrogen and phosphorous from agricultural sources. Many natural water Read More…

Seal scarers used by fish farms branded ‘sonic torture’
