In this study, reproduction and larvae development of Peppered Cory (Corydoras palaetus Jenys, 1842) of Callichthyidae were investigated. The study was carried out in the breeding unit of Sinop Fisheries Faculty on Ondokuz Mayıs University. Four couple mature of Corydoras paleatus was used. These fish started to show reproduction behavior while female fish reached minimum average of 5.625 ±0.125cm, while male’s fish reached average of 4.875 ±0.125 cm. After the application of cold water process they showed reproduction behavior and took T-position and started to lay eggs. Minimum 43 eggs, maximum 168 eggs were laid in one reproduction period. Fish laid their eggs completely in 3.5-4.5 hours, eggs clutch size (the egg quantity of laying eggs in each period) were determined as minimum 4 eggs maximum 7 eggs. The egg diameter was obtained average as 1.799 ±0.0214 mm, incubation periods were carried on minimum 96 hours, maximum 113 hours and average 102 hours in 24 ±2 º C. The average hatching ratio of eggs was found % 87,115 and eggs laying period were determined as 20-35
