GAINESVILLE, Fla. — A 20-year plan to dramatically reduce phosphorus levels of agricultural water entering the Florida Everglades is working, thanks to proper implementation of best management practices by growers, training by the University of Florida’s Institute of Food and Agricultural Sciences, and cooperation with state and federal agencies.
“It is a partnership that has worked,” said Samira Daroub, a professor of soil and water science at the UF/IFAS Everglades Research and Education Center in Belle Glade. “It is one of the success stories in the area and also in the country.” (more …)
GAINESVILLE, Fla. — Nearly half of Floridians eat more seafood than they did five to 10 years ago, but 40 percent still do not eat the federally recommended dietary intake of seafood, a new UF/IFAS and Florida Sea Grant-funded survey shows.
Floridians also know seafood is good for them, and they like their seafood caught or harvested in the Sunshine State. But many are not sure they’d know Florida seafood if they saw it, and they’re hesitant to pay the higher cost of local seafood.
“We know that eating Florida seafood is important to consumers,” said Florida Sea Grant Agent Bryan Fluech. Consumers want to support fishermen and the local economy, the survey says.
UF/IFAS experts say they can help educate consumers and the seafood industry to close these gaps.
“Specific educational programs could focus on developing a ‘train-the-trainer’ model for restaurant and retail staff,” said Fluech. That’s because most consumers purchase their seafood from restaurants and grocery stores, although they are not confident that they are getting accurate information from these sources. “Such a program would help these workers better address customer questions and needs, while promoting Florida seafood.”

GAINESVILLE, Fla. — As the University of Florida prepares to embark on the 2015-16 academic year, the College of Agricultural and Life Sciences offers several courses and majors that reflect how the institution adapts to industry and stakeholder needs.
The courses and majors aren’t brand new for this fall. They evolved during the past few years. But they reflect the growing menu of courses and majors offered to the more than 3,700 undergraduate students expected to enroll at UF CALS this fall.
Just to name a few of the relatively new majors and course offerings, UF CALS offers a major in marine sciences that leads to a bachelor’s degree, a new undergraduate certificate titled “Challenge 2050: Global Leadership and Change” from the Challenge 2050 Project and three new majors offered in the Food Science and Human Nutrition Department that were previously specializations under one major – Food Science and Human Nutrition.

GAINESVILLE, Fla. — Spiny lobsters practice “behavioral immunity” to create safe havens that prevent them from contracting a lethal disease in the wild, an important finding for the $50 million annual spiny lobster fishery in Florida, according to a new study co-authored by a University of Florida scientist.
UF/IFAS Associate Professor Don Behringer worked with Old Dominion University Professor Mark Butler on the study, published online June 10 in the journal PLOS ONE. In the study, scientists showed how the Caribbean spiny lobster uses a form of behavioral immunity to prevent the spread of the PaV1 virus, which takes a heavy toll on their populations.
“Increased infection risk has long been deemed a cost for the many benefits of being a social animal. However, we have shown that a social marine animal, the spiny lobster, has developed behaviors to reduce disease transmission by avoiding infected individuals,” said Behringer, a UF/IFAS scientist in the School of Forest Resources and Conservation Program in Fisheries and Aquatic Science. “Further, this behavioral immunity keeps potential epidemics of PaV1 from occurring.”

GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers are using data from fishing tournaments to gauge how non-native largemouth bass in Africa are invading lakes and preying on smaller, native fish, a huge cost-saving measure in fisheries management.
Largemouth bass are native to North America, but they have been distributed worldwide for recreational fishing. When they’re in waters outside North America, largemouth bass can cause declines in native fish abundance, disrupting the ecosystem.
UF fisheries and aquatic sciences Professor Micheal Allen and his colleagues at UF/IFAS and in South Africa used existing fish-catch data from bass tournaments in southern Africa, where largemouth bass are non-native and invasive. Scientists examined data from 40 bass tournaments in lakes in Botswana, Mozambique, Namibia, South Africa and Zimbabwe. They compared that information with 41 bass tournaments in the U.S., where bass are native species, between 2011 and 2014.
They found that angler catch data were similar between southern Africa and the U.S. Their data proves that the number and weight of the fish caught by recreational fishermen can be used to monitor the spread of exotic fish that are commonly caught by anglers.
GAINESVILLE, Fla. — George Baker hopes to help ensure Gulf seafood remains safe to consume.
As the new seafood safety specialist for Florida Sea Grant, Baker will primarily give seafood processors the best scientific data from the University of Florida Institute of Food and Agricultural Sciences and other sources.
He’ll train processors and others in seafood safety. Baker wants to help develop methods to detect chemical compounds that would hinder seafood safety, and he hopes to generate and disseminate basic nutritional information or analysis.
“Working with seafood can be very exciting and quite challenging,” said Baker, who, in addition to his new Sea Grant position, will retain his appointment as an assistant professor in food science and human nutrition at UF/IFAS. “It seems that there are far more safety issues associated with seafood in the news or on the web than other food commodities like meat and poultry or produce. However, it’s my opinion that, unless you have a seafood-related allergy, seafood is as just as safe, or safer, than other food.”
The Alaska salmon fishery is touted as one of the best in the world. When measured with an ecological yardstick, it is – fish stocks are healthy and the fishery is certified by the Marine Stewardship Council as consistently meeting rigorous biological standards. Fish are individually counted as they swim upstream to ensure there are enough to breed.
But Alaska salmon falls behind some of the world’s fisheries in how it benefits local fishermen, processing workers and nearby rural communities, according to a new assessment that ranks the vitality of a fishery by looking at its economic and community benefits as well as its ecological health.
“We wanted to develop a new set of metrics to determine how well fisheries management systems work and to test what factors are most effective in improving them,” said James Anderson, professor of Food and Resource Economics and director of the new Institute for Sustainable Food Systems at the University of Florida Institute of Food and Agricultural Sciences. Anderson is a lead author of a paper published May 6 in the journal PLOS ONE, describing the new methodology.
“These new Fishery Performance Indicators (FPIs) are designed to help us evaluate a fishery system’s performance toward achieving economic, community and ecological sustainability – the ‘triple bottom line,'” he said.

GAINESVILLE, Fla. — As Florida Sea Grant’s new Gulf oil spill research Extension specialist, Monica Wilson translates oil spill science to Gulf Coast residents and stakeholders.
Her audiences include commercial, recreational and for-hire fishermen, natural resource managers, elected officials, emergency responders and managers, tourism specialists, port and harbor employees and more.
Wilson works with three other specialists, one from each of the Sea Grant programs in the Gulf – Mississippi-Alabama, Louisiana and Texas — to create a new science education program that disseminates key oil spill research results to industry and community audiences. They hope to disseminate bulletins soon about dispersants as well as fisheries.
As Wilson works with Sea Grant programs in nearby Gulf states, she and other specialists bring different expertise to foster a more comprehensive understanding of oil spill science.

GAINESVILLE, Fla. — Five years after the explosion of the Deepwater Horizon oil rig killed 11 men and sent at least 210 million gallons of oil spewing into the Gulf of Mexico, people along the coast are gathering for a three-city regional forum Thursday. Participants will discuss the spill’s effects on their communities, its lasting impacts and how to prepare for another major disaster.
The regional forum will include the release of results from a University of Florida Institute of Food and Agricultural Sciences survey of Gulf Coast residents from Baldwin County, Ala., to Cedar Key, Fla. The survey looked at coastal residents’ opinions of the status of their recovery five years after the DWH disaster.
Findings indicated that respondents’ levels of satisfaction were lower five years after the spill than before it in several topic areas. This included levels of satisfaction with their community’s economy, community leadership and programs, local media, Gulf coast seafood industry, faith-based organizations and emergency response efforts.

GAINESVILLE, Fla. — A sampling of more than 1,000 Gulf of Mexico fish, shrimp, oysters and blue crabs taken from Cedar Key, Fla., to Mobile Bay, Ala., between 2011 to 2013, shows no elevated contaminant levels, according to a seafood safety study conducted by Dr. Andrew Kane and colleagues at the University of Florida. In fact, some 74 percent of the seafood tested showed no quantifiable levels of oil contaminants at all.
“Seafood appears as safe to eat now as it was before the spill,” said Kane, associate professor of environmental and global health and director of the Aquatic Pathobiology Laboratory at UF’s Emerging Pathogens Institute. (more …)
