“…Biochemical analyses such as blood chemistry analyses often provide vital information aiding the diagnosis for health assessment and management of cultured fish [35][36][37]. These results confirm previous findings by Abdel-Tawwab et al [38][39][40] that biochemical parameters were improved in fish fed probiotic during their study on the use of commercial probiotic as a growth and immunity promoter for Nile tilapia.…”

Digeston-1 (fermented soybean meal) is produced by controlled lactic acid fermentation with natural lactic acid bacteria. In the present study, a total of 150 fish with average initial body weight 10.11 g were randomly stocked into 15 aquaria to study the effect of Digeston-1 on performance and growth parameters of Nile tilapia (Oreochromis niloticus) fingerlings. Results revealed that the group fed diet contain Digeston-1 recorded the highest (P<0.05) growth parameters in terms of final body weight gain, average daily gain and specific growth rate compared with those fed the control diet. The Nile tilapia in the trial groups consumed less feed, which led to a considerable reduction of the feed costs. The results also showed that the FCR, PER and PPV% were high significantly (P<0.05) for fish fed diet containing Digeston-1 compared to fed control diet. Body composition; DM, CP, EE, Ash and energy content of Nile tilapia during the experiment showed no changes in whole body composition among all experimental diets. Results of Hematological parameters (WBCs, RBCs, Hb, PCV and Differential leucocytes count) of fish fed diets containing various levels of Digeston-1 indicated that there were no significant (P>0.05) differences among the tested dietary treatments. The treated diets had slightly higher white blood cells count, red blood cells count, hemoglobin and PCV than control diet. On contrast, total protein was increased (P>0.05) by Digeston-1 supplementation specifically, by 0.50% and 0.70% level. Moreover, Digeston-1 supplementation had no significant effect (P>0.05) on Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentrations compared with unsupplemented group. It is concluded that the addition of Digeston-1 diets at 0.5% level improve and enhance the growth performance of Nile tilapia, Oreochromis niloticus, fingerlings.

“…niloticus (Lara-Flores et al, 2003) in response to Streptococcus faecium, Lactobacillus acidophilus and Saccharomyces cerevisiae. niloticus in response to Bacillus licheniformis and yeast extract (Hassaan et al, 2014) and suggested that change in chemical composition of fish in response to probiotic supplementation may be related to better nutrient digestibility and absorption (Abdel-Tawwab et al, 2008) and efficient conversion of ingested food into structural proteins that resulted in more muscles (Mehrabi et al, 2011). Thus, improved flesh qualityof rohu (fry)of experimental group may be due to enhance digestion and absorption of nutrient due to proteolytic and lipolytic activity of G. candidum-QAUGC01 (Abu Bakar, 2014).…”

The present study was designed to test whether administration of single strain probiotic during early reaing could improve the survival and growth of rohu, L.rohita. Seventy days experiment was conducted in replicate of three and twelve hundred postlarvae (average wet body weight, 0.60 ± 0.05 mg) were equally distributed in two groups , control and treated (n=200 postlarvae /fiberglass tank). Both groups received similar feed except addition of probiotic,Geotrichum candidum,QAUGC01 in the rearing water of treated group. Postlarvae raised in the presence of probiotic showed significantly higher (P<0.05) survival rate, improved growth performance (weight gain and specific growth rate), enhanced intestinal protease, amylase and cellulase activity and significantly lower mortality (P = 0.003) after challenge with Staphylococcus aureus. Moreover, proximate composition also showed significantly (P<0.05) higher values of crude protein and considerably lower levels of ash content in muscle of fry reared on probiotic supplementation. This study is the first report on the beneficial effects of single locally isolated strainof G. candidum as probiotic on early life stages of L. rohita and suggests an economically viable way to boost fish production.

“…Data in Table 4 show different count in psychrophilic count in common carp intestine; the higher was in the control group with 600×10 4 , the lowest count obtained in the T5 with 0×10 4 , the same trend showed in the coliform counts in fish intestine in which the highest was in T3 with 35×10 2 but the lowest in T5 with 2×10. In the study of Abdel-Tawwab et al (2008), the results of bacteria challenge, bactericidal activity, and NBT suggest the increase in phagocytosis in blood, which have an important role for prevention of infectious disease. Phagocytosis by these cells is a process of internalization, killing and digestion of invading microorganisms, in phagocytosis; phagocytes produce oxygen free radicals during the respiratory burst, which is toxic to bacteria as regards to our results observed in Table 5, an increase in Spirulina level leads to lowest the coliform counts but it causing to increase the coliform in T4.…”

A b s t r a c t A r t i c l e I n f oThe use of the microalgae Spirulina in aquaculture has several potential advantages over the production of fish. This study was designed to investigate the effect of different replacement levels of fishmeal with Spirulina on some microbiology counts of common carp Cyprinus carpio L., the trail was conducted for 105 days and for this purpose 200 fingerlings common carp had been used. Five experimental diets were used and Spirulina replaced fishmeal protein from the standard diet at0% (T1), 5% (T2), 10% (T3), 15% (T4) and 20% (T5) levels. Psychrophilic count, coliform and Escherichia coli in common carp muscle, intestine and water rearing had been examined in which no psychrophilic bacteria in carp muscles were found as compared to control that were contain 16×10 4 , and the count of coliform bacteria decreased as the ratio of Spirulina increased in the diets, the highest was in control 1.2×10 2 while the lowest was in T3 with 2×10. Different count of psychrophilic bacteria were in common carp intestine; the higher was in the control group with 600×10 4 , while the lowest count obtained in the T5 with 0×10 4 , the same trend had been shown in the coliform counts in fish intestine in which the highest was in T3 with 35×10 2 but the lowest was in T5 with 2×10. The control showed lowest results in psychrophilic count in rearing water with 2×10 and the highest were in other treatments, regarding coliform counts the lowest value had been shown in T2 and T3 (1.5×10 2 and 1.5×102 ) respectively and the highest was in T4 (4×10 2 ).
