Climate change will have an adverse impact on trophic amplification in marine food webs
Climate-driven changes in ocean environmental conditions — ocean warming, deoxygenation and acidification — are projected to affect the physiological functions of marine organisms, their geographic distributions, biological life cycles and total biomass.
Fish species show surprisingly narrow combination of traits
The world’s waterbodies are filled with predatory fish feeding on other animals from zooplankton to squid and other fish, while “vegetarian” or herbivore fish are rare. Researchers has analyzed the key traits – size, productivity and trophic level – of over 31,000 fish species recorded in FishBase.
Protecting 30 per cent of the ocean by 2030 would barely impact fisheries
Sea Around Us presents a multi-objective solution that could lead to the protection of 89% of the ocean’s Representative Biodiversity Areas and 89% of threatened species or about 860 species, all while maintaining access to fishing grounds that provide 89% of the global catch.
IOF researchers use salmon scales to track sockeye in the high seas
Knowing where different salmon stocks forage will be essential for identifying the unique environmental threats they will face as oceans become more inhospitable due to climate change and other cumulative impacts.
STUDENT PROFILE: Samantha Ramirez
I’m creating a model that will predict the hypoxic conditions of freshwater streams years from now. This will help governmental organizations know where to focus their conservation efforts in terms of which streams are going to be the most impacted by our changing environment, said Ramirez.
Salmon diet database gives researchers a new “window into the lives of salmon”
The database fill gaps in scientists’ understanding of the late marine phase of the salmon life cycle
Management of exploited transboundary fish stocks requires international cooperation
With an average catch of 48 million tonnes per year, and USD $77 billion in annual fishing revenue, transboundary species support critical fisheries, and require international cooperation to manage.
New World Wildlife Fund reports call for better policy to save fish from climate change
IOF’s Drs. Juan Jose Alava and William Cheung contributed to two WWF reports.
Popular fish species disappear from Turkey’s Marmara and Black Seas
Bluefin tuna, swordfish and Atlantic mackerel are among the fish species considered commercially extinct or extirpated on the Turkish side of the Marmara and Black Seas.
New use for museum fish specimens
Some fish are difficult to reach and a museum specimen may be the only known representative of the species. Using preserved fish specimens is a more precise way to learn.
