Fisheries Research and Development Gulf Specimen pioneered the development of two new commercial fisheries, rock shrimp and cannonball jellyfish. Rock shrimp, a species new to science, was discovered in the Gulf of Mexico by the Florida Department of Natural Resources. In 1971, Jack Rudloe was the first to attempt to establish a commercial market for rock shrimp as a new seafood species, submitting samples to dealers and paying fishermen to land it for the first time. Rock shrimp is now a significant seafood product. | ||
 In 1990-92, Jack Rudloe traveled to China for the US Department of State to develop a commercial export market for American cannonball jellyfish. He researched and published techniques for the processing of jellyfish, an Asian delicacy. He also traveled to Malaysia for the same purpose. After Florida voters passed the 1996 ban on net fishing, state money was used to develop workshops based on Rudloe’s work to train dislocated commercial fishermen. Commercial jellyfish processing was done in Gulf and Duval counties in subsequent years. | ||
| Biomedical Collaborations | ||
   Bryostatin - Beginning in 1968, GSML was the first supplier of marine species to the National Cancer Institute’s Natural Products Division which looks for new cancer drugs in other species. Over a period of 20 years, Gulf Specimen supplied hundreds of species for screening to NCI. Of these, bryostatin, a compound found only in the bryozoan Bugula neritina, was one of the most promising and led to extensive scientific research and publications. By 2003, bryostatin had received clinical approval for the treatment of esophageal cancer and was in the final stages for approval as a breast cancer drug. | ||
 Electrical Ray Neurobiology Research - In the mid 1980s, the Howard Hughes Medical Institute contracted with Gulf Specimen Marine Laboratory (then called the Panacea Institute of Marine Science) to provide lesser electric rays, Narcine brasiliensis, for neurophysiological research into the biochemistry of the neurotransmitter acetylcholine. Since nothing was known of the biology or distribution of the species, GSML did extensive survey, ecological and behavioral research in
conjunction with the project. In 2003, federally funded research began at GSML on technological applications of biomagnetism in Narcine. | ||
 Limulus Lysate - Field studies funded by the US Food and Drug Administration measured the impact of biomedical blood collection on long term survival of horseshoe crabs. The results were used to develop conservation protocols to insure that biomedical use would not reduce the populations of this species. | ||
