Nile tilapia (Oreochromis niloticus) is a freshwater fishery commodity that has commercial value. Very fast growth and has a distinctive meat taste make tilapia so popular with people both in Indonesia and abroad. However, a decrease in water quality can affect growth, including the hatchability of tilapia eggs. This study aims to determine the effect of water quality given papaya leaf extract (Carica papaya) with different doses on the hatchability of nile tilapia (Oreochromis niloticus) eggs. The method used is the experimental method. Data were analyzed using multiple linear regression to determine the effect of water quality on the hatchability of Nile tilapia eggs. The research results obtained were temperatures ranging from 25.1 to 27.50C, for pH ranging from 6.1 to 8.53, and for DO ranging from 5.16 to 6.70 and still within optimal limits for the hatching and growth of Nile tilapia eggs (Oreochromis niloticus). The research results found that temperature and pH had a small effect on the hatchability of Nile tilapia eggs, respectively 16.79% and 16.44%, while dissolved oxygen had a large effect on the hatchability of fish eggs, a value of 86.21. %.
