Article: Froehlich HE, Gentry RR, Rust MB, Grimm D, Halpern BS (2017) Public Perceptions of Aquaculture: Evaluating Spatiotemporal Patterns of Sentiment around the World. PLoS ONE 12(1): e0169281. doi:10.1371/journal.pone.0169281 Aquaculture is one of the fastest growing industries in the world. A 2014 report by the UN-FAO estimated global freshwater and marine farming to constitute 44% of all […]
Fish have provided sustenance for millions of people, but in a world where stocks are rapidly depleting, what are the consequences of trying to save and rehabilitate their populations?
Why do some restaurants join sustainable seafood eco-labeling programs? A new study identifies some motivating factors that can help the continued expansion of these programs to enhance their ability to harness consumer demand and encourage positive change in seafood production.
An ecosystem model predicts how the Puget Sound ecosystem could be affected as the popular geoduck aquaculture industry increases. Including mediating affects, such as changes in predator refuges, allowed ecosystem-wide changes to be uncovered. For example, a decrease in seabirds was predicted due to shifts in prey populations resulting from the anti-predation guards for geoducks.
Mycotoxins in fish feed threaten the health of fish, consumers, and the aquaculture market. The more we learn and understand about these toxins, the more effective regulations can be. Read more to find out how complicated mycotoxin science can be, and how its complexity plays into setting safety standards.
We eat oily fish to get the health benefits of omega-3 fatty acids. However, the level of omega-3s in farmed salmon is changing. How does this stack up to wild-caught salmon? Read more to find out!
Many industries have been trying to figure out how to make their waste products into useful raw materials for other products. Read on to find out how mussel aquaculture could contribute to your next lobster dinner!
Feed for farmed seafood is relying on more land-based ingredients. As aquaculture production is projected to increase in response to rising human demand, the consequences for resource use and human health is changing. Read more to find out how!
Abalone are an economically and culturally important group of edible sea snails, and a new study demonstrates that they’re at serious risk of decline due to ocean acidification.
Ever wanted to know what it’s like to go to a scientific conference? Here’s a summary of what conferences are all about, plus the four most interesting talks I saw at this year’s National Shellfisheries Association meeting.
Lox and lice. Not a combination of critters you envision when planning your Sunday brunch. Unfortunately, an increase in drug resistant sea lice is threatening both wild and farmed salmonid populations.
An increase in the number of positive cages and cage-level abundance of sea lice in southern Chile was shown since 2004. The prevalence of sea lice in the fish farms was 53.4%, and the average sea lice abundance was 11.8 per fish (poor salmon)! In order to gain control over parasites, synthetic pyrethoid has been invented and put into use. However, pyrethoid is released to the ocean after treatment and has the potential to harm non-target organism, such as copepods, benthonic crustaceans and mussels. Passive sampling is a promising way for monitoring these compounds in the water. It is much cheaper and simpler than actively collecting liters of water!
Microplastics constitute the large majority of plastic pollution in our global oceans. Microplastic fibers are small fibers that might not be visible to the naked eye, but can be found on virtually every coastline. Researchers in Halifax, Nova Scotia looked for these fibers in beach sediments, worm fecal casts, and both natural and farmed mussels – see what they found here!
