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 productionSignificance statement: This study provides the costs and value of lost production due to regulations for the ornamental aquaculture industry in Florida.The results of this study will help to streamline the regulatory framework for ornamental aquaculture farmers in Florida and help to grow the industry as a whole.

Emerging research on aquaculture governance has pointed to the conundrum of negative global environmental effects from economic incentives for aquaculture production to shift from more highly regulated to less regulated countries. This study has focused on examining whether regulatory costs on U.S. tilapia farms may have contributed to their contraction in contrast to the growth of global tilapia production that contributes to the volume of seafood imports into the U.S. A national survey (coverage rate = 75% of tilapia sold; response rate = 18%) found that on-farm regulatory costs accounted for 15% of total production costs on U.S. tilapia farms, the fifth-highest cost of production. The total direct regulatory costs nationally were $4.4 million, averaging $137,611/farm. Most problematic were regulations of effluent discharge, predatory bird control, international export, and water and energy policies. Manpower costs for monitoring and reporting were the greatest cost of regulatory compliance. The lost sales revenue resulting from regulations was $32 million a year, or 82% of total annual sales, indicating that the regulatory framework has constrained the growth of U.S. tilapia farming. The smallest tilapia farms had the greatest regulatory cost per kg. This study provides evidence that regulatory costs, along with other challenges related to live fish markets, have contributed to the decline in U.S. tilapia production. Increased competitiveness of the U.S. tilapia industry will require a combination of: (1) improved regulatory efficiency that reduces on-farm cost burdens without reducing societal benefits; (2) research and on-farm extension assistance to evaluate new tilapia fillet equipment; and (3) research on changing consumer preferences to provide guidance on effective strategies to penetrate the large U.S. fillet market.

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.

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.
