GAINESVILLE, Fla. — Of all the invasive plants in Florida’s waterways, hydrilla costs the most to contain — $66 million over a seven-year period, a University of Florida Institute of Food and Agricultural Sciences researcher says.
But UF/IFAS researchers are finding new ways to use less chemical treatment, and thus less money, to manage hydrilla.
From 2008 to 2015, state and federal water resource managers spent about $125 million to control invasive aquatic plants, according to an April Extension document co-written by Lyn Gettys, a UF/IFAS assistant professor of agronomy and aquatic weed specialist.

Of that $125 million, about $66 million goes to control hydrilla, according to the Florida Fish and Wildlife Conservation Commission.

GAINESVILLE, Fla. — If grocers put nutrition labels on packages of raw fish — a good nutrient source for cardiovascular health — parents may be more likely to buy the fish, a new University of Florida Institute of Food and Agricultural Sciences study shows.
Xiang Bi, a UF/IFAS assistant professor of food and resource economics, worked with her colleagues to survey 1,000 people online to gauge consumer reactions to raw fish with nutrition labels. Until 2012, federal rules only required nutrition labels on processed and commercial foods. That year, the federal government started requiring raw meat and poultry products to carry nutrition information on their labels.
In the new study, researchers focused on three types of information: nutrition, health and a combination of nutrition and health. By putting the same nutrition label on raw seafood packages as consumers can find on raw packages of meat, consumers are more willing to buy the raw seafood, the study found. This finding may interest the seafood industry, grocers and policy makers, the study says.
GAINESVILLE, Fla. — Faculty, administrators and friends of the University of Florida Institute of Food and Agricultural Sciences now know even more about the fine foods and beverages produces by UF/IFAS faculty after the annual May 9 Flavors of Florida event.
Jack Payne, UF senior vice president for agriculture and natural resources, commended faculty and thanked friends for attending.
“Flavors of Florida is a chance for UF/IFAS to showcase the many fine foods and beverages developed by our world-renowned scientists to not only make food tastier and more nutritious but to help growers sell more food at the grocery store,” Payne said. “And with the help of our many friends around Florida, we can continue the laboratory and field research necessary to continue producing these incredible foods.”
GAINESVILLE, Fla. — Whether it’s hybrid termites, grain pathogens, mosquito mating or something in between, University of Florida Institute of Food and Agricultural Sciences researchers are studying important topics and helping to solve global issues.
The UF/IFAS Research Dean’s Office recently recognized more than two dozen UF/IFAS faculty members for their impactful research, and Dean for Research Jackie Burns said she could not be more proud of the scientists.
“We recognize that these research articles are examples of the many published by UF/IFAS that are highly impactful and help reach solutions to worldwide issues including food shortages, nutrition, diseases and economic development,” Burns said. “Our faculty perform top-quality, globally-recognized scientific work, and we’re proud to recognize them.”

GAINESVILLE, Fla. — When you eat a shrimp, you probably want it to be juicy. That’s why University of Florida Institute of Food and Agricultural Sciences researchers are trying to find alternatives to phosphates to lock in that texture and savory flavor.
Normally, phosphate or table salt is used to retain moisture in meat and seafood, said Paul Sarnoski, a UF/IFAS assistant professor of food science and human nutrition. But adding salt to the food puts more salt in a person’s diet, and that’s unhealthy, Sarnoski said. Additionally, phosphates are relatively expensive, he said.
In a study recently published in the Journal of Food Science, Sarnoski and his UF/IFAS colleagues found that phosphate alternatives such as polysaccharides – a type of carbohydrate often used as a food additive – can help retain water in shrimp. UF/IFAS scientists tested the shrimp using phosphates and polysaccharides. They boiled, froze and dried the crustaceans to see how much water the shrimp lost.
GAINESVILLE, Fla. — A University of Florida Institute of Food and Agricultural Sciences professor wrote an article 30 years ago that’s still so significant that a scientific journal has recognized it as an “enduring” article.
James Anderson, a UF/IFAS professor of food and resource economics and director of the UF/IFAS Institute for Sustainable Food Systems, has been honored by the journal Marine Resource Economics for his 1985 paper, “Market Interactions between Aquaculture and the Common-Property Commercial Fishery.”
“I was quite surprised and honored, especially since it was the first time the award was given, and at the time the article was written, almost no one in the economics profession was giving any attention to the economics of aquaculture and its relationship to traditional capture fisheries,” Anderson said. Capture fisheries are found mostly offshore. “Most articles written 30 years ago have been forgotten, but I know some researchers are still looking at this one – that’s a good feeling.”
GAINESVILLE, Fla. — The world’s fisheries are a great source of protein, but even with the best management, they won’t be able to meet the needs of a global population expected to exceed nine billion by 2050, a University of Florida Institute of Food and Agricultural Sciences resource economics expert said.
Aquaculture must grow, said James Anderson, a UF/IFAS food and resource economics professor.
Aquaculture production is expected increase by more than 60 percent and account for nearly two-thirds of all seafood supplied for human consumption by 2030, said Anderson, who’s also director of the UF/IFAS Institute for Sustainable Food Systems.
Anderson made his remarks at the opening plenary of the Aquaculture 2016 Conference in Las Vegas, Feb. 23.

GAINESVILLE, Fla. — Birds and alligators may not seem to be the likeliest of friends, but their interactions help both species to survive in Florida wetlands, according to research by scientists with the University of Florida Institute of Food and Agricultural Sciences.
“We have known for some time that ibises, storks, spoonbills and herons seem to always have alligators underneath their nests. Alligators are serving as nest protectors – keeping raccoons out of the colony, which are otherwise devastating nest predators,” said Peter Frederick, a professor in the department of wildlife ecology and conservation.
In the most recent research, graduate student Lucas Nell tells the story from the alligator’s perspective. Birds typically hatch one to two more chicks than they can actually provide food for, and this means that one or two usually die at some point, he explained. “Many of the dead chicks end up in the water, and their potential contribution as alligator food is substantial. In fact, we estimate that in years with especially high bird nesting, most of the breeding female alligators in the Everglades could be supported during the four–month dry season by dropped chicks alone,” Nell said.
GAINESVILLE, Fla. — Floridians say the state’s water resources are just as important as healthcare and the economy, according to researchers from the UF/IFAS Center for Public Issues Education in Agriculture and Natural Resources.
PIE Center researchers presented 523 state residents with a list of 10 issues. Only two-tenths of a percent separated what the respondents tagged as the three most critical issues.
When asked to describe the significance of each issue between “not at all important” to “extremely important,” 81.5 percent of Floridians deemed healthcare highly or extremely important, compared to water at 81.4 percent and the economy at 81.3 percent. Fifty-two percent of Floridians believed that water was an extremely important issue.
BELLE GLADE, Fla. — University of Florida scientists at the Everglades Research and Education Center have found an important way to control the destructive rice water weevil, one of the major pests in rice production.
UF Institute of Food and Agricultural Sciences researcher Ron Cherry and his team discovered that shallow flooding of rice fields can help reduce rice water weevil populations during Florida’s growing season, between April and September. Previous studies of the effect of flood depth on the pest have been inconsistent. (more …)
