Thirty-one fish eggs and larvae families were identified about 18 of total fish eggs and 100 of wholte larvae . Cu Lao Cham - Thu Bon river has the richest species composition as 18 families following to that is Ly Son - Tra Bong - Sa Ky and lower is Nha Trang - Nha Phu identified 15 and 10 families respectively. The highest frequency was found in families such as Mullidae Engraulidae and Synodontidae with 2 to 3 species groups . The above families account for about 60 of the total number of fish eggs and larvae collected. The average fish eggs and larvae abundance about 3 630 eggs 1 000 m3 of water and 122 larvae 1 000 m3 of water. The highest eggs density is Nha Trang - Nha Phu and the highest larvae density is Cu Lao Cham - Thu Bon river. Ly Son - Tra Bong - Sa Ky areas have eggs density lower than other areas especially for larvae density with 22 larvae 1 000 m3 of water.
