Candidate Species for Marine Ornamental Aquaculture: Porkfish, Anisotremis virginicus

Figure 1. Adult porkfish.The porkfish is a member of the grunt family, which create a characteristic “grunting” sound by rubbing their pharyngeal teeth together during periods of agitation or courtship. Many species of grunts are popular in public aquariums because they?re abundantly available, and their schooling behavior and bright colors create interest in aquarium exhibits. Porkfish also have additional appeal to aquarists because they are “cleaner” fish during their juvenile phase, picking parasites from larger fish and other vertebrates. Scientists and aquarists have recently achieved a greater understanding of appropriate aquaculture protocols for grunts in general and porkfish in particular. These characteristics and advancements have led to porkfish being identified as a candidate species for commercial aquaculture.

Description of Enhanced-Efficiency Fertilizers for Use in Vegetable Production

Figure 1. Urea-formaldehyde slow-release fertilizer.In response to the Federal Clean Water Act of 1972 and the Florida Restoration Act of 1999, a series of best management practices (BMPs) was implemented to improve surface and ground water quality. BMPs are cultural practices that, when implemented as a plan, help reduce the environmental impact of production while maintaining yield and quality. One of these BMPs includes the use of controlled-release fertilizer, which is an enhanced-efficiency fertilizer. This publication describes the common enhanced-efficiency fertilizers and the factors affecting their use in Florida vegetable production. This 9-page fact sheet was written by Luther Carson and Monica Ozores-Hampton, and published by the UF Department of Horticultural Sciences, October 2014.

Using the Delphi Technique to Achieve Consensus: A Tool for Guiding Extension Programs

Figure 2. Basic steps in the Delphi process (Geist, 2010; Schindler, 2013).The ability to achieve a group consensus may be critical during specific activities throughout an Extension professional’s career. For example, it may be important to identify an advisory committee’s highest priorities or a group of stakeholders’ most important programmatic needs. The Delphi method has been recognized as a suitable alternative to interviews and formal meetings in certain circumstances. This 6-page fact sheet provides an overview of the Delphi method and suggestions for using this technique to support Extension programming. Written by Laura A. Warner, and published by the UF Department of Agricultural Education and Communication, October 2014.

The Impact of Fathers on Children's Well-Being

father talking to young son.American families have changed dramatically over the last century. Currently, about half the children in the United States will live apart from their fathers some time during their childhood because their parents have separated and the proportion of births to unmarried women has risen from 5 percent in 1960 to 41 percent in 2011. But a father who is absent from the household may not necessarily be absent from his child’s life. This 5-page fact sheet provides a brief summary of the history of fatherhood in America and discusses the importance of involved fathers, and how mothers, other family members, and adult role models can make a positive impact in a child’s life. Written by Sarah M. Ellis, Yasmin S. Khan, Victor W. Harris, Ricki McWilliams, and Diana Converse, and published by the UF Department of Family Youth and Community Sciences, October 2014.

Dr. Wendell Porter (far right) instructs 4H members participating in science and technology activities during the 2011 4H Congress.  UF/IFAS Photo by Tyler Jones.STEM is an acronym for science, technology, engineering, and math. In Extension, our purpose is to share the knowledge or products created through Ag-STEM research and design by universities and government agencies. Finding effective solutions to agricultural issues, especially in urban areas, increasingly involves working with clientele to solve problems jointly. Therefore, emphasizing the connections of STEM to agricultural problems through Ag-Extension programming can help our public audiences comprehend the problem-solving system underlying the content. The goal is to provide public audiences with self-confidence and skills in STEM, preparing them to be more engaged in the problem-solving process for the challenges ahead.

Measuring Community Resilience using Online Toolkits

A canal close to the beach in Naples, Florida.  When we return to the scene of recent disasters like New Orleans, we find that some communities and neighborhoods are able to recover faster than others, while some never completely recover. Community Resilience is defined as the ability for a community to bounce back from a disaster, adapt to changes, and become more sustainable. The resilience assessment and planning tools reviewed here range from simple, ready-to-print worksheets intended for use by average citizens to comprehensive planning exercises more appropriate for city planners, emergency service providers, and elected officials. Not all of the toolkits will apply to every community. This 6-page fact sheet was written by Paul Monaghan, Emily Ott, and Timothy Fogarty, and published by the UF Department of Agricultural Education and Communication, July 2014.

It assumed that a list of phone numbers, such as program registration lists, is available for conducting program evaluations or assessing needs. When volunteers or staff assist with the survey by interviewing respondents, this data collection method can be economical and effective. Careful attention is needed when developing the questionnaire and supporting materials and when orienting interviewers in order to obtain credible survey data. In the right situation, telephone surveys can be a valuable tool for Extension agents and specialists. This 7-page fact sheet was written by Glenn D. Israel and Jessica L. Gouldthorpe, and published by the UF Department of Agricultural Education and Communication, October 2014.

Tracking the Economic Benefits Generated by the Hard Clam Aquaculture Industry in Florida

handful of clams The hard clam industry is a true success story for commercial aquaculture in Florida. From a cottage industry borne of reductions in commercial wild clam harvests in the Indian River Lagoon during the late 1980s, hard clam aquaculture has now developed into an industry that is rivaled by no other aquaculture food product in Florida. Although successful by virtually any metric, the risks and uncertainty associated with commercial hard clam culture has led to the evaluation of programs that help mitigate risk, such as the former pilot Cultivated Clam Crop Insurance Program administered by USDA Risk Management Agency. All of this alludes to the economic importance of the hard clam culture industry which, through the cultivation process and sales of products, generates local income and taxes, creates jobs and businesses, and draws new money into the local economy, as cultured hard clams are sold to non-residents and buyers outside the region and state. This 6-page fact sheet provides an overview of a recent study by the University of Florida to provide an estimate of the impact of the hard clam industry to the Florida economy. Written by Charles Adams, Leslie Sturmer, and Alan Hodges, and published by the UF Department of Food and Resource Economics, October 2014. (UF/IFAS photo by Tom Wright)

Conflicts between People and the Florida Black Bear

Figure 1. A Florida black bear searching for food. Prevent problems before they start with bear-resistant garbage cans.An adult black bear may eat up to the equivalent calorie content of 38 Big Mac sandwiches a day, and can smell food from one to two miles away. Garbage is the main attractant, but bears are also attracted by bee hives, pet food, barbeque grills, fruit trees, and bird (or wildlife) feeders. Conflicts between people and black bears arise when people fail to remove or secure potential food sources. In their search for food, black bears may damage property and threaten, injure, or kill pets and livestock in order to gain access to their feed. This 5-page fact sheet provides tips for preventing human-bear conflicts and tells how to report conflicts if they happen. Written by Elizabeth F. Pienaar, and published by the UF Department of Wildlife Ecology and Conservation, September 2014.

The Four Rs of Fertilizer Management

4 R's: right rate, right source, right placement, right timingSupplying needed nutrients for crop production involves attention to four major fertilization factors (the 4Rs): right rate, right source, right placement, and right timing. Attention to these factors will provide adequate nutrition for crop production while minimizing the risk of loss of nutrients to the environment. In this publication each factor is described, as well as how the information can be provided from a soil test report. While not a formal part of the 4Rs, the importance of irrigation to overall nutrient management is stressed in this 4-page fact sheet written by George Hochmuth, Rao Mylavarapu, and Ed Hanlon, and published by the UF Department of Soil and Water Science, October 2014.

Fertilizer Recommendation Philosophies

Figure 2. Incorporating fertilizer for an experiment on fertilizer rate and source for tomato.Farmers receive varying fertilizer recommendations depending on which lab they consult because labs employ different chemical methods and procedures to analyze the samples and subscribe to different fertilizer recommendation philosophies. This 4-page fact sheet explains the main soil-test philosophies, their basis, and their applications, and explains why the Sufficiency Level of Available Nutrient philosophy (SLAN), also called the Crop Nutrient Requirement (CNR), is most likely to be the best to govern fertilizer recommendations in Florida today.
