Fecundity and diameter of fish eggs are very important to determine the ability of fish to reproduce and the ability to maintain their population. The purpose of this study was to determine how to calculate fecundity and egg diameter of sangkuriang catfish (Clarias gariepinus), to determine the relationship between fecundity and fish weight, to determine the relationship between fecundity and fish length and to determine the relationship between fecundity and total gonad weight of sangkuriang catfish (Clarias gariepinus). Fish fecundity was determined using the gravimetric method and egg diameter observations using a binocular stereo microscope. The results of observations that have been made from 30 samples of sangkuriang catfish (Clarias gariepinus) there are 24 samples containing gonads and 6 samples not having gonads. Of the 24 samples of gonads have Gonad Maturity Levels (TKG) III and IV. The highest fecundity of sangkuriang catfish (Clarias gariepinus) eggs was 65,760 eggs, the highest fecundity results were from the sample which had a total fish length of 32 cm, a fish weight of 220 grams and a gonad weight of 19.7 grams. The lowest fecundity of 20,606 grains was obtained from samples that had a total fish length of 27 cm, a fish weight of 100 grams and a gonad weight of 8.71 grams. There is a relationship between fish weight and total gonad weight with fecundity. Sangkuriang catfish (Clarias gariepinus) has an egg diameter ranging from 1 mm–1.9 mm.
