High Five: NIFA-Funded Research Improves Agriculture

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.

The National Institute of Food and Agriculture (NIFA) invests in agricultural sciences that turn research into action by taking groundbreaking discoveries from laboratories to farms, communities, and classrooms.  Scientific advances that result from NIFA-funded research – more than $1.5 billion in fiscal year 2015 – enhance the competitiveness of American agriculture, ensure the safety of the nation’s food supply, improve the nutrition and health of communities, sustain the environment and natural resources, and bolster the economy.  The following blogs are examples of the thousands of NIFA projects that impact the lives of Americans every day.

Farmer, Conservationists Partner to Build a Bridge for Salmon in Southern Maine

A just-completed project that restored a fish passage in southern Maine may have another benefit – preventing an environmental disaster on important salmon-spawning streams.

A new bridge that now crosses the Swan Pond Creek at the Al Dube Quarterhorse Farm in York County was the culmination of a year-long quest by the Saco River Salmon Club and Hatchery and the Natural Resources Conservation Service (NRCS) to rehabilitate a section of the creek for fish passage and rearing of juvenile salmon.

USDA Employee Named “Recovery Champion” for Oregon Chub Conservation Efforts

The Oregon Chub is making waves in history. This February, it became the first fish to be delisted from the Endangered Species List because of recovery (not extinction).

This success is directly attributable to more than 20 years of hard work by USDA’s Natural Resources Conservation Service (NRCS), the U.S. Fish and Wildlife Service (USFWS), the Oregon Department of Fish and Wildlife (ODFW), private landowners and other conservation partners.

While many people were involved in the recovery effort, the USFWS recognized 12 professionals who represent outstanding leadership in their respective agencies to recover the species. These individuals were honored during a “Recovery Champions” awards ceremony May 28 at the Finley National Wildlife Refuge in Corvallis, Oregon. Read more »

Nothing Fishy about Probiotics

After searching 15 years for a way to combat a devastating disease among salmonids (salmon and trout), researchers at Washington State University (WSU) and the University of Idaho (UI) found an answer inside the fish itself.

Dr. Kenneth Cain’s team at UI’s Aquaculture Research Institute cultured a bacteria from the fish’s gut (designated Enterobacter C6-6) and found that it inhibited the growth of Flavobacterium psychrophilum, the organism that causes Coldwater Disease.

Cain and Dr. Douglas Call, his WSU-based research partner since 2001, found that by adding C6-6 to fish feed as a probiotic they could limit the damage caused by Coldwater Disease – but they’re not quite sure why.  “We know that C6-6 produces a toxin,” Call said.  “This toxin kills the bacteria although we’re trying to get more funding to figure out how this works in the fish itself.” Read more »

For the Love of Trails and Trout

Accessed by the Blue Ridge Parkway and surrounded by the Black Balsam Mountains, the Sam Knob Project is located in one of the most scenic and highly visited portions of the Pisgah Ranger District. As we celebrate National Trails Day and National Fishing and Boating Week, we are highlighting this location as a showcase of how recreational trail design can protect critical fish and wildlife habitat and enhance user experiences.

Preserving a Way of Life for the Yakama Nation

Lamprey, or Asum in the native language, are a culturally significant food source to the Yakama Tribe. Here, Deputy Under Secretary Mills joins members of the Tribe in releasing lamprey into the Toppenish Creek as part of the tribe's reintroduction program. NRCS photo.

Recently, I visited the 1.1 million acre Yakama Nation reservation located in southwestern Washington State. Touring the reservation, I was able to see first hand how funds from the Regional Conservation Partnership Program (RCPP) will help the over 10,000 members of the Yakama tribe.

Through RCPP, NRCS is working with the tribe to accelerate the recovery of fish stocks, including the Middle Columbia Steelhead, reconnect floodplains and improve irrigation water conservation. Read more »
