Responsibility
Shrimp farmers can look to the chicken-farming industry for guidance on proper pond management. At the Nicovita Symposium in Ecuador, Dr. Dean Akiyama of Charoen Pokphand encouraged shrimp producers to overcome challenges at hatchery level.
Aquafeeds
The digestive systems of shrimp are main entry points for bacterial and viral pathogens, and unfavorable microflora. Natural feed additives that combine different actions have proven effective in improving survival where shrimp are exposed to bacterial pathogens.

This article reports on a breeding program focused only on the improvement of growth rates at associate farms in Ecuador. By applying a localized breeding strategy, the program has yielded an average 7.8 percent annual phenotypic gain for commercial growth rates, while survival has remained fairly constant.

The government of Ecuador has set the legal framework for leasing mariculture sites and the conditions under which to apply for a lease. This commitment to marine fish farming was also shown by the extension of credit lines.
Health & Welfare
One of the largest shrimp maturation operations in Ecuador is working with five major shrimp producers to improve growth rates.

The authors are exploring alternative models for shrimp breeding that address genotype-environment interactions with solutions that could advance breeding in South and Central America.

The PescaMaris shrimp farm in Ecuador uses fish peptide isolates to accelerate probiotic bacteria growth and improve water quality.
Responsibility
Recirculating systems, where probiotic, heterotrophic bacteria compete with pathogenic bacteria, can operate without antibiotics to produce tilapia and shrimp.
Intelligence
Tilapia culture in Ecuador is marked by vertically integrated companies that manufacture their own feeds and practice polyculture with Pacific white shrimp.
Responsibility
Some producers take advantage of shrimp's ability to tolerate a broad range of salinity variations by rearing in low-salinity waters.
Health & Welfare
The use of intensive raceway nursery systems to produce juvenile shrimp under biosecure conditions is an important WSSV management tool.
