Rising global maritime traffic could lead to sharp increases in invasive species around the world over the next 30 years, according to a new study by McGill University researchers. The findings, published in the journal Nature Sustainability, suggest that shipping growth will far outweigh climate change in the spread of non-indigenous pests to new environments in coming decades.
DNA barcoding of more than 1,400 Marine Stewardship Council (MSC) labelled products has shown that less than 1 percent were mislabeled, compared with a reported average global seafood mislabeling rate of 30 percent. These results published in the journal Current Biology suggests that the MSC's ecolabeling and Chain of Custody program is an effective deterrent for systematic and deliberate species substitution and fraud.
For the first time, researchers unveil the genome of ito-mozuku (Nemacystus decipiens), the popular Japanese brown seaweed, providing data that could help farmers better grow the health food.
The respiratory systems of Atlantic salmon function normally even when carrying large loads of piscine orthoreovirus (PRV), new University of British Columbia research has found. The results are a positive step in reducing the uncertainty about the potential of infected farmed Atlantic salmon in marine pens to negatively impact migrating wild Pacific salmon.
A UC Davis study documents an unprecedented number of southern marine species moving northward into California and as far north as Oregon during the 2014-2016 marine heatwave. Of 67 rare, warm-water species sightings observed, 37 had never been documented so far north before.
Using a combination of advanced satellite imaging and over 20 years of coral monitoring across the Reef, a team of researchers from Dalhousie University, ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE), the University of Adelaide and Lancaster University in the UK has found that chronic exposure to poor water quality is limiting the recovery rates of corals across wide swaths of the Great Barrier Reef.
Marine scientists from WCS (Wildlife Conservation Society) and other groups examining the ecological status of coral reefs across the Indian and Pacific oceans have uncovered an unsettling fact: even the best coral reef marine parks contain less than half of the fish biomass found in the most remote reefs that lie far from human settlements.
Researchers have shed light on the distribution of Japanese eel by analyzing environmental DNA (eDNA) from small samples of river water. This could enable faster and more effective surveys of Japanese eel populations, and help to conserve this endangered species. The finding was published on Feb. 27 in Aquatic Conservation: Marine and Freshwater Ecosystems.
Fish provide a vital source of protein for over half the world's population, with over 56 million people employed by or subsisting on fisheries. But climate change is beginning to disrupt the complex, interconnected systems that underpin this major source of food.
Many countries are engaged in a vast illegal and unrecorded international trade in seahorses, one that circumvents global regulations, according to new UBC study that has implications for many other animal species.
