WOS: 000357657500001 In this study, we investigated the effects of enzyme-producing probiotic bacteria isolated from the gastrointestinal tract of rainbow trout on the growth performance, feed conversion ratio, and digestive enzyme activity, of fry (Oncorhynchus mykiss). Three isolates (G8/2013, T7/2013 and U5/2013) of candidate bacteria elicited the highest protease, lipase, and amylase activities, respectively. Isolates were identified as Aeromonas sp., Bacillus sp. and Citrobacter braakii by morphological, physiological, biochemical characterizations as well as 16S rRNA gene sequence analysis. The fry basal diet was supplemented with probiotics at varying concentrations; G8 group, Aeromonas sp. 1.72 x 10(8) CFU/g; U5 group, Bacillus sp. 3.01 x 10(8) CFU/g; T7 group, C. braakii 2.96 x 10(8) CFU/g and a mixed group (same bacterial concentrations), and control group (no bacteria). The rainbow trout fry were fed ad libitum in triplicate treatments with supplemented and non-supplemented probiotic diets for 70-days. The total bacterial count in the intestine was significantly higher in the mixed group (30th and 50th days) and U5 group (50th and 70th days) compared with the control group. However, there was no significant difference in weight gain, specific growth rate (SGR), feed conversion ratio (FCR), nutrient digestibility, or digestive enzyme activity among the groups.

In this study, the effects of CaCl2 (2%) supplemented diet, rock salt (RS, 2%) supplemented diet and control diet (no supplement) on the weight gain, specific growth rate, daily feed intake, feed conversion rate, protein efficiency rate and serum mineral concentration (Na, K, Cl) were investigated in rainbow trout. RS was used for increasing the CAD and Na/K ratio of the control diet and CaCl2 was used for decreasing the CAD level of the control diet. A total of 300 fish, 2 replications for each treatment consisting of 50 fish with a mean initial body weight of 88.2 g were used in the experiment. The experiment lasted fifteen weeks. The diet supplemented with 2% RS improved significantly the weight gain, feed conversion rate and protein efficiency rate in rainbow trout compared to 2% CaCl2 supplemented group and control (P0.05). Dietary 2% CaCl2 supplementation did not significantly affect the weight gain, specific growth rate, daily feed intake, feed conversion rate and protein efficiency rate in rainbow trout compared to control diet (P>0.05). Na, K and Cl level of the serum and mortality rate were not statistically different among the groups (P>0.05). The dietary 2% RS supplementation produced a better growth and feed efficiency for rainbow trout compared to dietary 2% CaCl2 supplementation and control diet. Added RS to diet was appropriate for making cationic the diet and increasing the CAD level and Na/K ratio of diet.

Experiment had performed in rectangular tanks that 60cm. x20cm. x210cm. dimensions. Every tanks were seperated by a nets of tull. Every compartment were contained 60 larvae that 53 age days old. These larvae had fed with living material, (Art emi a sp. ) for along 7 days. The groups of 1A and 2A were fed with ' 1 number im mic- roparticle feed 1 mm. diameter that contains 55 percent pro tein, 13 percent fatty. The groups of IB and 2B were fed with 2 number i micrap articular feed in same diameter that contains 63 percent crude protein, 10 percent crude fatty. The other group had fed with only Artemia sp. (metanauplii) (originated by Sanfransisko.) and Uaphnia magna. 25` percent feed had given to larvae for kgs. living body weight. Calcu lated percentage of living feed have based on wet weight. ?or along first 5 days the group of 1A and 2A have fed with 80 yo living l Artemia sp.- metanauplii ) plus 20£- Pınar 1 number microparticuiar feed, group IB and 2B have fed with 80 'p living plub-20 % 2 number microparticuiar feed. Bet ween 6-10days of experiment had fed with 60 Jİ3 living plus -40 % microparticuiar feed, between ll-15days 4-0 fo living plus - 60 yo micropartucular feed, 16-20 days 20 % living plus - 80 % microparticuiar feed respectively. Between 21~30days whole microparticuiar feed have used for feeding. The group of 10 and 20 were fed -with Artemia sp. metanauo. untill 75 days old. 75 days old after they have fed with Daphnia magna in the rate of 30 c/o body weight. In this experimentation nitrit, amonium and orthophosphat weekly, oxygen everyday, temperature 3 times in a day were measured values were not cause as lethal level.72 At the result of this experimentation period the gain of weight rate 87 % and 90 #, increase of body length 4-7 % and 50 %, survival rat 73 # and 82 # have fomnd in the groups of feed with ı number '. - and 2. number respectively. Ob served gain of weigth, increase of length and survival rate were 85, 4-5, 50 percent respectively in the group of feed w with living material. The differences of gain of body weight, totally length and dorsal heigh were no statiscally import ance. It has determined that statiacalls important differences (P^O.Ol) between all three groups by the point of view of. Body weight gain, totally body length and dorsal height. Hovewer the best result were obtained to feed with 2 number Statiscall values have calculated by the method of DUNCAN. The correlations and regrations were linearly between living weight-body length, living weight -dorsal height, body lenght- -dorsal height, in the groups of 1A,13,1C,2A,2B,2C. The correlation coefficients were found 0.79, 0.88, 0.75, 0.Ş1, 0.87, 0.76, respectively for ecah groups. In the result I suggested that: In the period of 60-90days microparticular feed can be used instead of living material, but, transition from living to microparticular feed must be increased gradually in the period of 5 weeks. 85
