AquaSol, Inc. was contracted to further the technical development of tilapia farming operations at El Rosario, S.A. Prior to our involvement, this company was utilizing polyculture of tilapia and shrimp, stocking 115-150 gram Tilapia with Litopenaeus vannamei at 0.2 and 11 per meter square respectively for the final growout. While the practice netted some improvement in survival (3-4%) of the farm-raised shrimp, it was not providing a completely satisfactory or economically viable solution. El Rosario, S.A. was faced with an urgent need to find a solution to the White Spot Syndrome Virus (WSSV) and contacted AquaSol, Inc. for assistance.


AquaSol, Inc. developed a strategic aquaculture plan to convert two of the largest vertically integrated shrimp farming operations in Ecuador to Tilapia farming operations. One of these farms was El Rosario. Together, these two farms covered more than 4,000 hectares of shrimp farming area. Recommendations were given on Tilapia hatchery production, Tilapia growout production, fish feed quality, and the design and develpoment of a Tilapia processing plant. The strategic reorganizational plan was successfully implemented under the guidance of a former associate of AquaSol and the operations eventually developed into two of the largest producers of Tilapia in Latin America.
