    The Effects of Regulation on Ornamental Aquaculture Farms in Florida
    Boldt, Noah C.; Van Senten, Jonathan; Engle, Carole R.; Cassiano, Eric J.; DiMaggio, Matthew A. (University of Florida George A. Smathers Libraries, 2022-11-01)
    Florida’s diverse ornamental aquaculture industry has many unique challenges that set it apart from other aquaculture commodity groups.  The numerous production techniques, diversity of species, and various market outlets make the ornamental aquaculture industry an intriguing study in how regulations impact the industry.  By understanding those regulatory impacts, we can streamline efforts to address them.  A study was conducted to measure the regulatory impact on ornamental aquaculture farms in Florida using on-farm data from 2018. All farms were censused in the state and results covered 82% of the industry with a response rate of 41% of farms. This factsheet discusses the results of that study and the regulatory burden that the ornamental aquaculture industry in Florida endures.

    Investigations into Early Larval Feeding Practices for the Tiger Barb Puntigrus tetrazona
    Lipscomb, Taylor N.; Durland Donahou, Allison; Yanong, Roy P.; Boldt, Noah C.; DiMaggio, Matthew A. (Wiley, 2022-01)
    The Tiger Barb Puntigrus tetrazona is one of the highest trade volume freshwater species in the ornamental fish industry. Culture of larval Tiger Barb is largely dependent on live feeds at first feeding and throughout early life stages, leading to increased cost relative to the use of commercially produced microparticulate diets (MDs). Potential for the successful culture of Tiger Barb by using MDs from first feeding was evaluated here, with a focus on the physiological characteristics that limit digestive capacity in larval cyprinids, as well as the hypothetical benefit of including feed attractants in formulated larval feeds. Comparable growth and survival were achieved for the first 14 d of feeding with one of three MDs when compared to feeding with brine shrimp Artemia spp. Histological preparation revealed evidence for a fully functional pharyngeal jaw structure, including pharyngeal teeth and a pharyngeal pad, from 6 d posthatch, which coincided with first feeding. The masticatory function of these structures likely facilitated the breakdown and subsequent utilization of the relatively complex macronutrients that are characteristic of MDs. Inclusion of top-coated potential attractants (tryptophan, taurine, trimethylglycine betaine, or a mix of the three) with the most successful MD from the original trial failed to induce an increased feeding response, as evidenced by the observation of similar feeding incidence, total larval protein content, and tryptic enzyme activity relative to a negative control MD without added attractants. The results of this research suggest that the successful culture of larval Tiger Barb is possible with the use of commercially available MDs, potentially leading to cost savings and increased resilience of producers in the ornamental aquaculture industry.

    A regulatory cost assessment of ornamental aquaculture farms in Florida
    Boldt, Noah C.; Engle, Carole R.; van Senten, Jonathan; Cassiano, Eric J.; DiMaggio, Matthew A. (Wiley, 2022)
    The ornamental aquaculture trade is a diverse sector of aquaculture and faces unique challenges that other commodity groups do not have to contend with. The various production techniques, species, and destination markets make ornamental aquaculture an interesting study in how regulations impact the industry. In Florida, aquaculture is primarily regulated under the Florida Department of Agriculture and Consumer Services, unique from other states. Regulatory costs and the value of lost production on ornamental farms in Florida were estimated to be $5.2 and $23.2 million, respectively. Results from an industry-wide census have shown that there is a high regulatory burden on ornamental farmers for some regulatory categories. These include issues of legal control of fish-eating predators, the restriction of drugs and chemicals, which would be beneficial to production, and the prohibition for farmers to raise species that have been restricted for culture at the national and state level. Larger farms were also able to limit the impact from regulations better than smaller farms by spreading their regulatory costs and value of lost production across greater sales. Although the values of lost production were high for ornamental producers, direct regulatory costs were low compared with other aquaculture commodities demonstrating that the industry in Florida may prove a regulatory model for other sectors.
