Hard Clam Culture
     Hard clam (Mercenaria mercenaria) culture has become a priority of Florida Sea Grant's investment in aquaculture research and extension. Florida Sea Grant aquaculture specialists were instrumental in obtaining sanctions to allow hard clam growers to qualify for USDA crop insurance — the first eligibility of its kind for marine aquaculture in the United States.
     As well, adequate seed availability has been a major hindrance to the development of the industry in the southeastern U.S. particularly when critical shortages have occurred. Florida Sea Grant researchers have developed hard clam remote setting technology, adapting from the Pacific Northwest molluscan shellfish industry experience to suit Florida clam farmers. Remote setting will allow southeast nursery operators and growers to become less dependent upon traditional seed sources. See report
     Recently, aquaculture specialists have also developed a user-friendly Microsoft Excel program to help commercial hard clam growers with day-to-day business management decisions, periodic loan application information requirements, and the documentation of changes in inventory that may be needed for crop insurance. The software lets growers track clams from the original seed purchase, through nursery/grow-out planting, to final harvest. It also helps account for operating expenses and capital purchases. Plus, a map feature maintains an up-to-date picture of the location of nursery and grow-out bags on the lease site.

Ornamental Species
     In Florida, marine aquarium species are primarily collected from the wild (about $4 million annually) while farm-level sales of freshwater ornamental fish and aquatic plants oreached $64 million in 2001. Florida Sea Grant's goal is to increase the culture of marine ornamentals to generate economic activity in Florida while protecting wild-caught stocks.
     Florida Sea Grant was the lead sponsor and organizer of the international conference on marine ornamental species, Marine Ornamentals 2001: Collection, Culture & Conservation. Building on the first conference organized by Hawaii Sea Grant, 19 sponsors including nine Sea Grant programs, joined to create a program that attracted 336 participants from 23 countries. Program evaluations showed that 67% of the attendees would attend a subsequent conference and 91% indicated that the conference should be continued as is or expanded.
     Iowa State Press has recently published a book containing the scientific papers from the conference. The book is titled Marine Ornamental Species: Collection, Culture, and Conservation, and is co-authored by Florida Sea Grant director James Cato and Christopher L. Brown, director of the marine biology program at Florida International University.
