Vibrio infections are an increasingly common problem in intensive shrimp culture. As evidenced by study results, weekly Vibrio monitoring can be a useful tool for predicting bacterial disease outbreaks.
Health & Welfare
The authors conducted studies to test the performance of young shrimp postlarvae in systems with different approaches to aeration and water handling. Proactive management through proper feed applications and water quality control were critical elements.
Aquafeeds
The results of recent feed trial research showed potential profitability for the combination of good shrimp production from a biofloc-dominated super-intensive grow-out raceway system achieved with effective diets.
Health & Welfare
In ongoing trials of greenhouse-enclosed intensive biofloc shrimp culture systems, the objectives of a 2012 study were to evaluate the performance of fast-growth shrimp fed a commercial diet formulated for high-density culture systems, and to further evaluate injector performance in the zero-exchange, super-intensive raceways.
Responsibility
Research at the Texas AgriLife Research Mariculture Laboratory is investigating ways to improve the economic viability of super-intensive raceways for shrimp production.
Responsibility
Shrimp production studies using biofloc technology at the AgriLife Research Mariculture Lab in Texas evaluated different approaches to maintain water quality.

Cottonseed meal is high in protein and less expensive than fishmeal and soybean meal. Cotton plants can be engineered without gossypol in their seeds.
Health & Welfare
A study demonstrated that market-size shrimp can be profitably produced with zero water exchange in intensive raceways. The reuse of water that served for an earlier nursery study allowed the immediate establishment of a healthy microbial community in the grow-out study.
Health & Welfare
In a study, three probiotics applied to shrimp pond water throughout a culture period were not effective in preventing Vibrio harveyi outbreaks.
Health & Welfare
Despite research challenges, ongoing work on phytase supplementation in shrimp is striving to enhance shrimp feed performance in similar ways.
Responsibility
Although widely used in aquaculture applications, some synthetic polymer liners can release toxic substances into culture water and affect animal health.

OceanBoy Farms in Southern Central Florida has been a leader in establishing commercial protocols for inland, low-salinity shrimp farms.
Aquafeeds
Aquafeed study showed that an experimental diet with low levels of vegetable replacements for marine ingredients still produced acceptable results.
Innovation & Investment
OceanBoy Farms is developing a commercial inland farm for shrimp that includes a greenhouse-enclosed nursery with HDPE-lined raceways.
