| Summary, etc. | Dry matter and apparent protein digestibility coefficients were determined in Saro therodon niloticus fry of mean weight 21 mg maintained on four artificial diets with pro tein content ranging from 9.6% (Diet 1) to 30.4% (Diet 4) at salinities of 0°/00, 5°/00 and 10°/00. The total digestibility estimates made using faecal material accumulated through the night did not significantly differ (P > 0.05) from those estimates based on faecal mate rial collected during the day time; between feedings. The mean apparent total, protein and energy digestibility of the different groups of fry ranged from 56.7% to 69.1%, 71.7% to 87.1% and 73.6% to 83.9%, respectively. The dry matter digestibility, in all experimen tal groups of fry, showed a significant decrease when the dietary protein content changed from 9.6% to 30.4%. Salinity had no significant effect on the digestibility of any of the four experimental diets. In S. niloticus maintained on Diets 3 and 4 at salinities of 5°/00 and 10o/oo the total and protein digestibility showed daily variation. Generally a day or two of high digestibility was followed by a day of low digestibility. The possible utilization of this rhythmicity, whether apparent or real, in aquacultural practices to reduce the feed costs is suggested.<br/> |
