Abstract
This study aimed to illustrate healthy and profitable alternative culture method for Oreochromis niloticus with wheat. Six earthen ponds (4200 m²) were used in this study. Fish farming has been two successive seasons separated by cultivating wheat in the winter period. Fish farming of O. niloticus in the first season was in the period 15/5/2012 until 21/10/2012 followed cultivating wheat in the period 5/11/2012 until 10/05/2013 followed farming O. niloticus in the period from 21/15/2013 until 27/10 /2013. O. niloticus fish were exposed to three treatments (Two replicates for each treatment). The first treatment fish were fed on artificial feed 25% crude protein only, in the second treatment fish were fed on artificial feed 25% crude protein with inorganic fertilization and in the third treatment fish were fed on artificial feed 25% crude protein with organic fertilization. The wheat was cultured without fertilization. O. niloticus fingerlings averaging 30.07g for first year and 30.83g for second year were assigned randomly (12000 fingerlings/ feddan). Results obtained can be summarized as follows: Season of aquaculture: the first season recorded the highest ranges of body weight (BW), body length (BL), condition factor (K), daily weight gain (DWG) and specific growth rate (SGR). Treatments: treatment3 recorded the highest ranges of body weight (BW), body length (BL), condition factor (K), daily weight gain (DWG) and specific growth rate (SGR). Wheat culture: third tratment recorded the highest ranges of total weight of Wheat crop. Based on results obtained in this study and on the economical evaluation, it could be concluded that, wheat can grow in the fish ponds during the winter season, taking into account feeding O. niloticus on a artificial feeding contain 25% crude protein in addition to organic fertilization using chicken manure also add organic fertilization to increase the weights of fish as well as increasing wheat crop of fish ponds, in addition to that it was the best in terms of economic efficiency compared with other treatments.
