Abstract
Four experimental isonitrogenous (33% crude protein) and isoenergitic diets were formulated to contain 0, 0.5, 1.0 and 2.0 % of dried caraway seeds meal (CSM) in order to study the effects of different levels of CSM on growth, survival, feed and nutrient utilization, attraction activity, nutrient digestibility, body composition and cost- benefit analysis of hybrid tilapia, Oreochromis niloticus x O. auraus, fingerlings. Eight glass aquaria (each holds 96-L capacity) were used in duplicates. Ten fish (stocking rate of 104 fish 1m3) of the same average weight (13 glfish) were stocked in each aquarium. Fish were fed daily at a rate of 3 % of the body weight, three times daily, six days a week for 112 days. Fish were weighed biweekly and feed amounts were adjusted on the basis of the new weight. Feces were collected daily during the last two weeks to determine apparent digestibility coefficients.
Results indicated that no significant differences (P>0.05) were observed in digestibility of dry matter, crude protein, ether extract and nitrogen free extract among fish fed all the tested diets. Fish fed 0.5% CSM was Significantly higher (P<0.05) in body weight, weight gain and SGR than those fed the control diet. However, growth performance parameters of fish fed CSM levels of 1 and 2% were insignificant (P>0.05). Fish fed 0.5% CSM diet was the best supplemented level for FCR, PER, PPV%, ER%, feed waste %, palatability index and profit index in comparison to the control diet and other tested CSM levels. Body composition did not affect by using various levels of CSM.
