Oyster Culture Project Gets Underway

Interest in oyster culture has recently been spurred on by decreased supplies from the fisheries and higher dockside prices, resulting in a favorable economic outlook. Additionally, the infrastructure provided by the hard clam culture industry supports development of new species for culture as well as serves as a model for Florida’s oyster industry in their recovery efforts. To assist in these efforts, the Florida Governor and Cabinet began in 2013 approving modification of clam leases, in which only six inches above the bottom substrate are allowed for culture activities, enabling growers full use of the water column for culturing oysters.

Virginia Continues to Lead in Cultured Clam and Oyster Production

The annual Virginia cultured shellfish assessment is available online in which a slight decline of 11% in 2015 oyster sales and a 25% reduction in clam harvests are reported, probably tied to the unusually brutal winter conditions last year. Even with these declines, Virginia remains the East Coast leader in cultured shellfish with well over $48.3M in sales. The survey conducted by the Virginia Institute of Marine Sciences (VIMS) shows hard clam sales of $32.3 million and $16 million in oyster sales. The values are according to the 10th annual Virginia Shellfish Aquaculture Situation and Outlook Report. The survey and report

Mechanical Harvesting Devices Approved for Cultured Shellfish

Governor Rick Scott has approved a legislative bill that will allow the use of handheld or hand-drawn hydraulically or mechanically operated devices in harvesting cultured clams from aquaculture leases. The bill (SB 1318) introduced by Senator Charles Dean passed overwhelmingly in the 2016 Florida Legislative Session. A companion bill (HB 489) was introduced by Representative Brad Drake. Detailed information on Senate Bill 1318: Shellfish Harvesting can be found here. The amendment to the Florida Aquaculture Policy Act (Chapter 597.010, F.S.) will become effective July 1, 2016. At that time, according to DACS Division of Aquaculture officials, clam growers may begin using these

New Fact Sheet: Molluscan Shellfish Aquaculture and Production

Molluscan shellfish aquaculture provides high quality and high value seafood for human consumption, and mollusks provide environmentally beneficial ecosystem services. In the past five decades, global fisheries and aquaculture have grown steadily, and seafood consumption per capita has increased. Molluscan shellfish has traditionally been a major component of world aquaculture. Today, mollusks are cultured in 76 countries. In the United States, molluscan aquaculture is a $329 million industry involving 756 farms in 18 states. An 8-page fact sheet written by UF/IFAS faculty provides a review of molluscan shellfish aquaculture and production worldwide and in the United States. Molluscan shellfish habitats,

A Strong El Niño is Predicted This Winter

Daily interactions between our oceans and atmosphere help shape the weather and climate we experience on Earth. However, naturally-occurring events such as El Niño can alter these interactions resulting in dramatic shifts in weather patterns across the globe. El Niño, also known as the El Niño Southern Oscillation, is characterized by periods of warmer tropical surface waters in the Pacific Ocean. El Niño episodes usually occur every three to seven years, but the last major El Niño period occurred during the 1997-1998 season.

Restoring Oyster Reefs in the Big Bend Provides Many Benefits

Oysters thrive under brackish conditions, and now a University of Florida (UF) study reveals that the bivalves can actually help create the mix of fresh water and brine they crave. While evaluating a new method of restoring degraded oyster reefs, researchers confirmed an observation that Cedar Key oystermen have made for years – some oyster reefs act as natural dams, impounding fresh water that flows seaward from nearby creeks and rivers. The result – large areas of reduced-salinity water that help maintain near-shore estuarine habitats supporting oysters, sea grasses, juvenile game fish, and invertebrates important to the marine food chain

UF IFAS Nature Coast Biological Station is Underway in Cedar Key

UF IFAS has a long history in research, teaching and extension programs in the Nature Coast (Big Bend) region. These previous efforts have built a foundation on which the Nature Coast Biological Station (NCBS) will further develop the UF IFAS mission. Dr. Mike Allen, a professor of Fisheries and Aquatic Science whose research has focused on population dynamics and ecology of fishes, was appointed director of the NCBS. He is working to build the research, outreach, and teaching programs to improve conservation, management, and sustainability of natural resources in this region.

Genetic Health of Wild and Cultured Florida Clam Stocks

So how much genetic diversity is present in hard clam hatchery stocks in Florida relative to the state’s wild populations? This was the focus of research conducted by Dr. James Austin and his doctoral student, John Hargrove, with the UF IFAS Department of Wildlife Ecology and Conservation. In order to address this question, samples were collected from six commercial clam hatcheries along with four wild populations sourced from the east coast of Florida. A standardized set of genetic markers was used to test if there were significant differences among the various sources.
