Snakehead fish ( Channa striata ) is a type of freshwater fish that has the potential to be developed because of its high economic value. Information about the reproductive biology of Channa striata is still limited, so it is necessary to carry out reproductive studies for its future development. Research on the aspects of reproductive biology such as the comparison of the weight of the broodstock (female) to the number of fecundities was carried out descriptively in December - January 2020. This study used three categories of broodstock parent size with different weights, namely (P1): 155-350 grams, (P2): 400-700 grams, (P3):> 700-1200 grams. The results showed that the number of eggs produced sequentially, namely (P1): 75,62.57 ± 1,106 eggs, (P2): 9,821.17 ± 628 eggs, (P3): 11,103.80 ± 2,307 eggs. This study concludes that the number of eggs produced increases with the larger size of the broodstock used. However, it was found that a consistent number of eggs were found at the parent size between 400 - 700 grams.
