    Oyster Demonstration Project

    Growers and UF researchers are evaluating the performance of triploid oysters to local conditions on Florida’s west coast.

  • Sunray venus seed can be produced in a hatchery using similar methods as for hard clams.

  • A native species, the sunray venus can be cultured in bottom bags or under bottom nets.

  • Sunray venus exhibit fast growth and can reach market from planting in about a year.

  • The plump meat of the sunray venus has a firm texture and delicate, sweet taste.

  • When cooked, the glossy shell of the sunray venus changes to an attractive peach color.

  • Industry #1

    The hard clam production process consists of three consecutive stages—hatchery, nursery, and growout to a marketable size.

  • Industry #2

    Clam farming begins in the hatchery with production of seed. Adult clams are induced to spawn by manipulating water temperatures.

  • Industry #3

    In the hatchery, larval clams are reared under controlled conditions in large tanks supplied with filtered seawater.

  • Industry #4

    During the hatchery phase, cultured marine microalgae are fed at increasing densities to larvae and post-set clams.

  • Industry #5

    Post-set clams are maintained in the hatchery until they reach about 1 mm. Over 100,000 seed are held in this downweller.

  • Industry #6

    The nursery is an intermediate step, where hatchery-produced seed are reared under semi-controlled conditions in land-based systems, such as these raceways.

  • Industry #7

    Another method of land-based nursery culture is the upweller system; some designs place the wellers, or cylinders, in the water.

  • Industry #8

    Clams are grown to market-size on coastal submerged lands leased from the State of Florida.

  • Industry #9

    When clam seed reach about 1/4”, they are stocked in polyester mesh bags and staked to the lease bottom for growout.

  • Industry #10

    After 15-18 months depending on season planted, littleneck-sized clams are harvested by pulling the bags off the bottom.

  • Industry #11

    Harvested clams are delivered to a certified shellfish wholesaler where they are prepared for processing and shipping to markets across the country.

    UF Gator Good Story

    The net ban and Cedar Key's success in replacing fishing with clam farming is featured as a UF Gator Good story.

The University of Florida (UF) Shellfish Aquaculture Extension Program provides educational, technical, and organizational support to the shellfish aquaculture industry in Florida. In 1995 a position was created within the UF Cooperative Extension Service to assist the emergent industry on Florida’s west coast in these efforts. Since then, the program has expanded to allow for statewide extension activities. This program maintains an affiliation with the UF Institute of Food and Agricultural Sciences (IFAS), UF School of Forest Resources and Conservation’s Program in Fisheries and Aquatic Sciences, and Florida Sea Grant. In addition, there is a multi-faceted partnership with local governments in coastal communities and the U.S. Department of Agriculture.
