Water supply improvement and isolation of native microalgae study at Primar Hatchery

Revise the estuarine water collection and treatment structure to improve the water quality of the Primar hatchery of Crassostrea gasar and produce isolated native microalgae feed for larvae of C. gasar

Based on previous projects and literature, a system to improve the catchment structure and treatment of estuarine water used at Primar's hatchery was developed. Further, samples of native microalgae were collected at a location close to the Primar hatchery. The microalgae were isolated and experimental production, subsequent tests, evaluations and adjustments were performed before pilot production of native microalgae for feeding of C. gasar was done. 
The data was collected during 2020 and 2023 at Primar hatchery, Brazil.
