Water quality management means efforts made to maintain water parameters so that they are in a safe condition, the standard of cultivation mediab required. Poor water quality will be the start of disease for shrimp and cn cause stress. Poor water quality can affect growth, metabolic processes and survival. Shrimp become low. The aim of this research is to find out whether the optimal quality management for the survival of vannamei shrimp (litopenaeus vannamei) at the reborn vannamei farm is optimal. The data alalysis method in this research uses quantitative descriptive analiysis techniques.The survival percentage of vaname shirmp from plot A 93,78%, plot B 92,68%, plot C 92,40% and plot D 90,38%. All plot showed a high survival rate from the standard value set by PT. Proteina Central Prima or CP Prima.

Understanding and knowledge about the application of management functions needs to be studied to facilitate the success of seeding activities. This research was carried out for 6 months located at PT. Top De Heus Askra Kendari fry. The aim of this research is to find out how the production process flows in the application of management functions in vannamei shrimp (Litopenaeus vannameii) hatchery activities at PT. Top De Heus Askra fry. The type of research used is qualitative descriptive research. The data sources used come from primary data and secondary data with the research methods used namely the listening method and skill method, while the techniques used are recording and note-taking techniques, and the analysis tool uses PESTEL analysis. The research results show that the production process flow is interrelated with the management function in vannamei shrimp hatchery activities so that goals can be achieved. At PT. Benur Top De Heus Askra's planning function includes preparation of suggestions and maintenance infrastructure as well as installation and management of the aeration system and the organizing function consists of dividing employee duties and responsibilities, directing, namely carrying out the duties and responsibilities of each employee, and supervision, namely evaluating each activity. The hatchery production process flow activities start from managing the aeration system, preparing brood rearing tanks, receiving broodstock, feeding, spawning broodstock, hatching eggs, preparing larval rearing tanks, stocking naupli, managing water quality, feeding and harvesting.
