Researchers from Sustainable Seas and Our Land & Water National Science Challenges are involved in a two-year project called Ki uta ki tai: Estuaries, thresholds and values, which includes interwoven critical steps funded by MfE.
NIWA’s Freshwater Species Programme Leader Dr Paul Franklin said World Fish Migration Day, on May 21, is a good time to remind New Zealanders of the challenges migratory fish face, and also the research that is underway to provide solutions.
Giant Redfin: Conserving South Africa’s Native Fish.Giant redfin and other freshwater species in the Cape Region face significant challenges.And the litany of challenges they face will be familiar to freshwater conservationists everywhere: invasive species, pollution, water quantity and habitat degradation.
Lyko led the ambitious genome study that established the extraordinary fact that all marbled crayfish originate from a single foundational female.
Inside is a computer containing an artificial intelligence-based detector that has been trained to identify targeted invasive weed species and log their locations in real-time."The development of these detector modules will enable a rapid and cost-effective detection and mapping that can be used over large areas.".
India boasts of a rich and vast freshwater resource network (rivers, lakes, wetlands, and groundwater), which occupies about 4 percent of the country’s area and supports its 1 billion people (17 percent of the world’s population).
It was clear from our visit to the Tapajós communities that they must be at the center of any conservation program, as the river and the resources in it are intimately linked to their identity, economic well-being, and deep social and cultural values.
Mannus Creek is one of many waterways in Australia that have been inundated with ash and debris following the devastating bush fires this spring and summer, killing fish and other aquatic life and fouling drinking water supplies.
Eel larvae face a long journey from their spawning grounds in unknown parts of the Western Pacific Ocean to the freshwater rivers and streams of New Zealand where they spend most of their lives.
A historic slow-moving flood of polluted Mississippi River water loaded with chemicals, pesticides, and human waste from 31 states and two Canadian provinces is draining straight into the marshes and bayous of the Gulf of Mexico —the nurseries of Arnesen’s fishing grounds—upsetting the delicate balance of salinity and destroying the fragile ecosystem in the process.
LakeSPI surveys have been carried out on 12 Rotorua Te Arawa lakes (Ōkāreka, Ōkaro, Ōkataina, Rerewhakaaitu, Rotoehu, Rotokākahi, Rotomā, Rotomāhana, Rotoiti, Rotorua, Tarawera, and Tikitapu) since 2005 and NIWA freshwater ecologist Tracey Burton says she has seen positive and negative changes.
NIWA freshwater fish scientists are trying to understand how long they can swim at given speeds – between rests - and how much variation there is between fish of the same species.
