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

<p>Revise the estuarine water collection and treatment structure to improve the water quality of the Primar hatchery of <i>Crassostrea gasar&nbsp;</i>and produce isolated native microalgae feed for larvae of <i>C. gasar</i></p><p>&nbsp;</p><p>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&nbsp;experimental production, subsequent tests, evaluations and adjustments were performed before pilot production of native microalgae for feeding of <i>C. gasar</i> was done.&nbsp;</p><p>The data was collected during 2020 and 2023 at Primar hatchery, Brazil.&nbsp;</p>
