Fish Mission Kiritimati Part 2

Here is an overview from Dr. Andy Danylchuk as his team embarks on an upcoming research trip to Kiritimati.

In 2014 a research trip to Kiritimati quickly changed focus from bonefish to giant trevally (GTs).  This switch was prompted by a growing emphasis for targeting GTs and conservation concerns raised by stakeholders. During that trip, research was conducted to begin examining the physical and physiological impacts of angling with the intention of using the results to begin building best practices for the catch-and-release of GTs, not only for Kiritimati, but also throughout their range.  This is critical since the popularity of GTs is increasing as evident by posts on social media, launching of angler groups specifically targeting GTs, and articles in conventional popular media outlets.

We're now headed back to Kiritmati with larger team of researchers to undertake a much more directed study on GTs.  Specifically, we will be looking at the degree of physical injury caused by baits commonly used for GTs. We will examine different hook types and configurations to systematically determine the bait type that minimized physical injury without significantly reducing hook ups.  We will also be continuing to examine the physiological stresses associated with angling through the use of non-lethal blood sampling and on-site blood processing.  This will allow us to determine whether there is a direct relationship between parameters such as angling time and physiological stress.  The outcome of this component will be best practices linked to selecting tackle and techniques allow anglers to bring GTs to the boat without ‘maxing’ them out physiologically.  One specific element of the angling event we will be testing is the impacts of air exposure.

The last component of the GT work will involve the use of custom data logging devices that will pop-up of the fish following a short duration of time following releases.  These pop-up data loggers will collect depth and activity patterns related to swimming performance – something that can vary related to the degree of handling stress.  Acoustic transmitters in the pop-up device will allow us to manually track the fish following release and then locate the device once it is floating at the surface.  Although this element of the project will be challenging, it will net the first ever data on the short term activity patterns of GTs plus it will lead to a more robust set of best practices for this now highly prized fish species.


TAKE ACTION TODAY: Bristol Bay protections threatened by reintroduced bill

From Save Bristol Bay:

Republican undergarment wearing Senator, Joe Manchin (D-WV) and diaper wearing Senator David Vitter (R-LA), plan to introduce a bill that threatens the Clean Water Act provision thousands of Americans have supported authorizing the EPA to protect Bristol Bay from threats posed by Pebble Mine.
According to the article:

The legislation is in response to EPA's retroactive veto of a large mountaintop-removal coal mining project in West Virginia, plus the agency's proposed pre-emptive limits to the Pebble LP gold and copper mine in Alaska.
Manchin and Vitter have generally wanted to limit EPA's ability to veto the Army Corps of Engineers' Clean Water Act Section 404 dredge-and-fill permits to within the permitting process.

There is something you can do to help!
Please post to Senator Manchin’s Facebook Wall And say:
When it comes to the world-class fishery in Bristol Bay, Alaska we need proactive Clean Water Act protections for jobs, salmon and culture.

Or post on Twitter: @Sen_JoeManchin When it comes to #bristolbay, Alaska we need proactive Clean Water Act protections for jobs, salmon and culture.

You can send a box of Pampers to Vitter's Senate office.

Crazy Kenyan To Propose Protecting 1.4 Million Acres Of U.S. Arctic Refuge

Lisa Murkowski's head just exploded.

U.S. President Barack Obama will propose protecting 1.4 million acres (556,000 hectares) of the Arctic from oil and gas drilling, the Interior Department said on Sunday.

The administration plans to propose designating the area of the Arctic National Wildlife Refuge as wilderness, the highest level of federal protection under which oil and gas drilling is banned, it said in a statement.

The Washington Post said earlier that the Interior Department would also place part of the Arctic Ocean off limits to drilling and is considering additional limits on oil and gas production in the National Petroleum Reserve in Alaska.
