Biological Control of Weeds: Is it Safe?

Carey Minteer, Eutychus Kariuki, and James Cuda

Invasive plants are non-native plant species that cause harm in their introduced range. Classical biological control of invasive plants is the use of natural enemies, imported insects and mites or pathogens, to control the target plants. This publication explains the strategies and rules in place to ensure that organisms released for the biological control of weeds are safe and effective.

Candidate Species for Florida Aquaculture: Almaco Jack, Seriola rivoliana

Victor Blanco, Cortney Ohs, Nicole Rhody, and Ronald Hans

Almaco jack, Seriola rivoliana, is a perciform within the order Perciformes, family Carangidae; which includes jacks and pompanos. They are members of the genus Seriola, a species of interest for aquaculture diversification worldwide. Like other commercially farmed Seriola species, almaco jack (also known as longfin yellowtail and kampachi) are fast growers, have a high market value, and are increasingly well-regarded among chefs for their versatility in both cooked and raw preparations. These characteristics, among others, have made them favorable candidates for both land-based and offshore aquaculture.

Candidate Species for Florida Aquaculture: American Horseshoe Crab Limulus polyphemus

Lena Donnarumma, Brittany J. Scharf, Jeffrey E. Hill, and Cortney L. Ohs

The American horseshoe crab, Limulus polyphemus, is a member of the phylum Arthropoda, subphylum Chelicerata, and class Merostomata. Although there are four horseshoe crab species worldwide, the American horseshoe crab is primarily found in the Atlantic Ocean along the East Coast of North America. The species ranges from Maine to Mexico, but is absent between Texas in the United States and Tabasco in Mexico. They mainly inhabit estuarine areas; however, juveniles and adults can venture into the shallow oceanic environments. Embryo development occurs in the intertidal zone of sandy beaches. Sandy or muddy bottom habitats are necessary for burrowing and benthic feeding. This publication will cover their natural history, aquaculture techniques, common diseases, and their uses and markets.

Brine shrimp live in and are harvested primarily from natural salt lakes and solar salt operations around the world. Two natural sources of brine shrimp in the United States are the Great Salt Lake in Utah and San Francisco Bay in California. Adult brine shrimp are also called "sea monkeys" and are used for entertainment or to feed aquarium fish. Brine shrimp can be used to observe, control, and manipulate a life cycle under laboratory conditions during a period of less than 2 weeks. They can be

Teach Aquaculture Curriculum: Fish-Eating Contest

Amber L. Garr, Cortney L. Ohs, Brian E. Myers, Craig S. Kasper, R. Leroy Creswell, Frank A. Chapman, Carlos V. Martinez, and Elisa J. Livengood

There are numerous fish species cultured in the world. Fish are cultured in ponds, tanks, and cages. Some are fed floating, pelleted food and some consume live algae. The types of diets used in aquaculture have been developed specifically for the feeding strategies of the cultured animal. In this lesson, students will mimic fish with different mouth positions by adopting different feeding behaviors and by trying to capture marshmallows without the use of their hands.

This activity will provide examples of volume and area calculations of ponds of various types and shapes. The students will learn to calculate volumes and surface areas of ponds and use this information to calculate stocking densities and chemical application rates. Students will be able to make these calculations in both US and metric units. This activity has direct application to aquaculture, and these calculations are commonly used by federal and state agencies, private companies, engineers, toxicologists, and other people related to the aquatic sciences.

The Citrus Red Mite (Panonychus citri): A Pest of Citrus Crops

Emilie Demard and Jawwad A. Qureshi

Panonychus citri is a phytophagous mite of economic importance in open citrus orchards and a major pest in Citrus Under Protective Screen (CUPS), a new undercover production system tested in Florida. Immatures and adults feed on citrus leaves, fruits, and green twigs resulting in mesophyll collapse, shoot dieback, and fruit drop. In Florida, P. citri occurs throughout the year but is most abundant in spring or early summer and autumn or early winter. Although chemical sprays like Abamectin or Fenbutatin oxide provide some control of P. citri, resistance has been reported in different regions of the world. Several predatory insects and mites have been shown to attack the mite and could be potential natural enemies to use in biological control programs.
