Aquaculture practices in the United States has increased significantly over the decades, and with increased production, the knowledge of raising fish in aquaculture has also increased. Specific areas in the United States have a well-established aquaculture infrastructure and therefore can access resources, such as disease treatments, easier, whereas limited-resource states have a minimally developed infrastructure and therefore may have a more difficult time accessing appropriate disease treatment options. Medicated feed treatments are essential when trying to treat internal bacterial infections, but this option may not be accessible for many limited-resource fish farmers. A questionnaire was given to fish farmers in limited-resource and large-scale aquaculture states to compare infrastructure and find any gaps within the industry. During the survey, 77.8% of participants in limited-resource states mentioned that they often treat with an external chemical treatment rather than medicated feed when an internal bacteria has been diagnosed due to how long it takes to obtain the medicated feed. Of the limited-resource fish farmers that used medicated feed, the majority, 22.2%, stated that it took between 11-15 days for the feed to arrive at their farm, and in large-scale aquaculture states the majority (66.5%) of participants stated that they could obtain the medicated feed within 0-4 days after diagnosis. If treatment options were more accessible in limited-resource aquaculture states, then fish farmers may choose the more appropriate treatment option when disease outbreaks occur and relieve or eliminate the pathogen before higher mortality occurs.
