“You’ll know,” says Kydd Pollock, fisheries science manager for The Nature Conservancy and research leader for the Fishing for Science program at Palmyra Atoll.He had substantial experience with a form of hand line: He tagged more than 2,500 sharks at Palmyra using the method.

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.

On the next Fishing for Science trip in February of this year, a scientific angler caught a bluefin trevally that had been tagged on February 6, 2020, at liberty for 753 days.Giant trevally caught and tagged on a Fishing for Science trip in February 2022.

That is thanks to an innovative partnership called FAD Watch Program between conservation and industry, specifically the US tuna fishing fleet, that is remotely tracking FADs to protect Palmyra, and provide important oceanographic data as well.

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.

“Hoki are one of the species we research – they have major spawning events, but we are currently only able to collect data on these for a few weeks every two years.NIWA hopes to be routinely using the vessel for monitoring fish within the next five years.

Thirty years of management informed by a raft of scientific research appears to now be paying dividends.In the Hauraki Gulf, commercial and recreational fishers are reporting improving catches, and NIWA scientists will soon be able to estimate whether the highly valued Hauraki Gulf snapper population is seeing a similar increase.

“The bay at the time was in a degraded condition, and fisheries managers thought blue catfish could provide something for people to fish for,” says Crum.

Lyko led the ambitious genome study that established the extraordinary fact that all marbled crayfish originate from a single foundational female.

I work hard to incorporate a little bit of outdoor fun into my desk job, so recently I found myself out with the NMDGF crew surveying fish in the Mimbres River.

In the noise of the Sanford processing shed In Auckland, NIWA scientists Rikki Taylor and Darren Parsons are measuring hundreds of fish from a catch that has just landed as well as removing otoliths to be measured back at the laboratory.

We hope that you enjoy this selection of the winning entries, with stories on everything from cassowary excrement to native trout conservation, from mothing as a hobby to essays on our childhood love of campground critters and The Crocodile Hunter.

The health of “entire ocean ecosystems” and food security is in jeopardy, said Dulvy, a former co-chair of the shark specialist group of the International Union for Conservation of Nature (IUCN).The number of species of sharks, rays, and chimaeras, known together as chondrichthyan fishes, facing “a global extinction crisis” has more than doubled in less than a decade, according to the paper published September 6 in the journal Current Biology.

Now, 3 years and a pandemic later, the base game itself and the online multiplayer mode Red Dead Online (RDO) continue to capture player’s attention through the story, characters, and open world exploration that Red Dead Redemption has come to be known for.

My friend, a visiting fish biologist, was thrilled to catch species new to him, like chiselmouth, largescale sucker and northern pikeminnow.It’s time to put the term “trash fish” in the trash, where it belongs, and give these fish the respect (and management) they deserve.

25 June 2021, Rome - The Food and Agriculture Organization of the United Nations (FAO), together with the Alliance of Bioversity International and The International Center for Tropical Agriculture (CIAT) released today a new study identifying hundreds of diverse plant and animal species that Indigenous Peoples around the world depend on and care for to generate food sustainably and enhance biodiversity - and warning of increasing threats to these sophisticated food systems.

The numberless catfish who now course through social media , the ones who devastate lives with sophisticated online masquerades, exist to beguile and disturb.In this way, she is akin to Nev's catfish, Angela, who turned him from a defeated dropout to a man with a purpose.

“This higher ingestion rate for flounder could be due to microplastics accumulating in marine sediments which makes up more of their diet compared to other species, or it could be because the flounder samples were all obtained from the Waitemata Harbour, which is closer to Auckland as a potential microplastic source,” she said.

“If you actually put your head underwater and take the time to listen, it's amazing what you'll hear,” Radford says.

But the Bureau of Ocean Energy Management delayed the project’s approval to review the cumulative impact of US offshore wind farms, while the company itself pulled its application to choose a different kind of turbine.

© Jacob Karst I’m on a quest to catch a fish in each of the 50 U.S. states – and to use each adventure as a means to explore conservation, the latest fisheries research and our complicated connections to the natural world.

NIWA seabird ecologist Dr David Thompson says while seabird tracking research has not been carried out for all albatrosses and large petrels in New Zealand, we know that several species also spend time in Chile and Peru, in Japan and the USA in the north Pacific Ocean, while others visit Namibia and South Africa.

“If you inadequately monitor these fisheries resources, successful and sustainable management cannot take place in a timely manner,” says Dr. Richard Ogutu-Ohwayo, who has studied and worked on Africa’s Great Lakes for over 40 years and is currently the Executive Director of AFLANET, the African Lakes Network.

Opportunities to Improve Fisheries Management through Innovative Technology and Advanced Data Systems.Yet, despite the proliferation of relevant consumer technology, integration of technologically advanced data systems into fisheries management remains the exception rather than the rule.

A recent article published in the journal Nature shows the potential for freshwater reserves by looking at a network of grassroots protected areas established in the Salween River basin of Thailand.
