Sign-up for USDA Farm Service Agency NAP Coverage

The Noninsured Crop Disaster Assistance Program (NAP), administered by the USDA Farm Service Agency (FSA), provides financial assistance to growers of non-insurable crops to protect against natural disasters that result in crop losses. NAP provides catastrophic level (CAT) coverage based on the amount of loss that exceeds 50% of expected production at 55% of the average market price for the crop. Beginning in 2015, additional coverage may be elected by growers by the application closing date; growers who buy-up coverage must pay a premium for that level of coverage in addition to the service fee. The NAP Fact Sheet can be viewed here.

2017 Census of Agriculture: Make Sure You Are Counted!

Fish, shellfish, plant, reptile, crustacean and other farmers that grow aquatic animals will soon have the opportunity to represent aquaculture in their communities, state and nationally by taking part in the 2017 Census of Agriculture. Conducted every five years by the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS), the census, to be mailed at the end of this year, is a complete count of all U.S. farms, ranches, and those who operate them. As examples of the importance of Census of Agriculture data, this information drives decision making by state and federal governments, manufacturers of aquaculture production gear,

New UF Growout Study Initiated

New UF Growout Study Initiated

The second phase of the demonstration project evaluates the performance of diploid and triploid oysters planted in early spring, as opposed to the first phase in which oysters were planted in late summer. In addition to seed provided to participants in March (see previous article), oysters of each ploidy type were field nursed by the UF project team at their experimental lease off Cedar Key in April. At that time, diploids were 29 mm in shell height (SH) and triploids were 34 mm. Oysters were stocked into 9 mm mesh Vexar bags at densities of 700 per bag. After seven

Consumer Evaluation of Cultured Oysters

Oysters typically acquire their flavor from their growing environment and are frequently named after their harvest location. Consumers can expect variations in appearance, color, aroma, taste, and mouth-feel that influence preferences, value, and reputation. Sensory attributes and acceptability can make the difference in market success of Florida cultured oysters. Diploid and triploid oysters harvested from the UF demonstration site in Cedar Key were delivered under refrigerated conditions to the UF/IFAS Food Science and Human Nutrition Department in Gainesville on May 24, 2017 for evaluation under the guidance of Dr. Charles Sims. All rules pertaining to harvesting and handling of oysters,

Next Crop of Seed Distributed

To quantify the effects of seasonal harvests on ploidy type, several spawns using tetraploid oysters held from the spring 2016 spawn were attempted in the fall at a participating commercial hatchery; however, viable gametes were not obtained. Since availability of triploid seed was limited, it was decided to purchase single-set seed with project funds from the Louisiana Sea Grant oyster hatchery and Auburn University shellfish hatchery. Disease certifications and ploidy verification required by the Department of Agriculture and Consumer Services for out-of-state oyster seed were obtained. These stocks were combined. A similar number of diploid seed was obtained from a

Harvesting UF Field Trials

Six months after seed oysters (average 25 mm in shell height) were stocked into 14 mm mesh Vexar bags (October 2016), they were harvested in April 2017 (12 months from spawn). Replicated field trials were conducted at the UF experimental lease within the Dog Island Aquaculture Use Area off Cedar Key to document the effects of ploidy (diploid versus triploid), stocking density (125, 150, 175 oysters/bag), and float design (square versus bullet) on oyster production. To determine growth, a sample of 35 oysters from each of the 42 bags (six replicate bags per treatment) were measured for shell height, length,
