Abstract

Tilapia nilotica were spawned in small-mesh net enclosures called hapas. During a 5-week period, eggs and fry were removed from mouth-brooding females at examination intervals of 2, 4, 7, or 10 d. A decrease in time between examination intervals increased the total number of spawns collected (P <0.05), but more spawns were obtained per examination for the 7- and 10-d intervals (P <0.05). For artificial incubation of eggs, the 7-d interval was considered optimal
