Abstract
Under monoculture semi-intensive system, a study on cultivation of monosex Nile tilapia (Oreochromis niloticus L.) in earthen ponds (each of 6000 m2) was done.Twelve rectangular earthen ponds were used representing six treatments, three different stocking density (SD1 , SD2 and SD3 being 9, 12 and 15 fish/m3, respectivily) within each of them two fish sizes (FS1 and FS2 being 30 and 50 g/fish, respectivily). Two replicates were used for each treatment. The treatment of 12 fish/m3 with 50 g/fish gave the best results of marketable size, net yield (8820.35 kg/feddan) and highest profit index (2.97 LE). Based on the obtained results, it could be recommended that the best fish size and stocking density of monosex Nile tilapia (O. niloticus) in monoculture semi- intensive system are 50 g /fiish at 12 fish/m3 to get the optimal marketable fish size at harrvest under similar conditions to those of the present study.
