abstract = {The intestinal microbial community of fish is determining by biotic and abiotic factors, and depending on the niche they occupy, we can distinguish between transient and permanent microorganisms. The last ones, are important for aquaculture, due to its probiotic potential. Three adult of Oncorhynchusmykiss were used to extract their intestine to isolate the bacteria present and tested to determine probiotic ability: resistance to acidic pH and bile, adhesion, hemolytic activity, antibiotic susceptibility, and in vitro antagonism. Bacteria groups were identified by sequencing the 16S rRNA. Fourteen bacterial strains were obtained, of which the strains Bacillus pumilus, Shewanella xiamenensis, Bacillus sp. and Bacillus methylotrophicus were able to grow at acidic pH in the presence of bile and only S. xiamenensis showed α-hemolytic activity. B. pumilus and Bacillus sp. had better adhesion and antagonism in vitro. We can conclude that B. pumilus and Bacillus sp. presented potential probiotics in vitro and is recommendable to evaluate them in rainbow trout to determine what benefits they can offer to this fish.},

abstract = {Algae are the main components of primary production in sea and refinery wastewater. Microalgae and cyanobacteria are the most-used groups. In the present study, refined wastewater was collected from drainage of a refinery in Gorgan to evaluate efficiency of two algae mixture, Scenedesmus obliquus and Chlorella vulgaris, to remove water nitrate, phosphate, BOD and COD during 14 days. An equal number of either of the algae (24000 cells) was added to each treatment at the experiment initiation. The algae number were daily counted; whereas, the media nitrate, phosphate, ammonia, chlorophyll-a, biomass, BOD and COD were measured every other day. At the end of study, phosphate was completely depleted in M50 treatment and the highest phosphate level (1 mg/l) was observed in M0 treatment (p <0.05). Water nitrate was completely depleted in M50 treatment. The highest biomass levels (0.4 g/l) were observed in M0 and M50 treatments (p <0.05). The highest chlorophyll-a was observed in M0 treatment (2.83 mg/l). BOD and COD had similar pattern among the treatments. The lowest COD was related to M50 treatment (5 mg/l); whereas the lowest BOD level was observed in M0 treatment (0.05 mg/l). Overall, the algae mixture was efficient to uptake nutrients and produce biomass and chlorophyll. },

Two 35 % protein experimental diets, FSBM (feed containing 21 % soybean meal) and FDW (feed having 21 % duckweed) as a source of protein were prepared and fed for twelve weeks. At the end of trial, the experimental diets showed a significant effect on the activities of intestinal digestive enzymes. There is significant (P<0.001) difference in the intestinal cellulase, protease and amylase enzymes in both Chinese carps. In culture systems, intestinal protease and amylase activities of fingerlings of C. idella fed FDW diets were significantly higher as compared to fish fed FSBM diet. In polyculture system, the intestinal amylase activity of H. molitrix fingerlings was significantly higher when fish offered FDW diet as compared to FSBM diet.The results of this study indicate the usage of L. minor as a protein source in polyculture system enhances the fish digestive capacity than monoculture system.},

abstract = {In aquaculture farms, growth is an essential factor in assessing the yield of inputs, welfare of organisms and accelerating sexual maturity; the objective of the investigation was to determine seminal quality with respect to weight: one, two, three and four kilograms. Ninety-four males were anesthetized with clover essence at a concentration of 0.05 mL L-1 of water. The semen was extracted by light abdominal pressure in the operculum-caudal direction. The sperm concentration was determined with Neubauer chamber, viability with eosin-nigrosin, estimated in percentage and motility was evaluated by activating with water. The results indicate that increasing the weight increases the volume. In the one kilogram males the mean volume was 8.0 ± 3.9 mL, in those of two 11.1 ± 6.1 mL, in those of three 12.3 ± 8.3 mL and in those of four 29.2 ± 21.8 mL. On the other hand, the sperm concentration mL-1 showed an inverse tendency to the volume being the two kilograms males who showed the highest concentration 6.80 ± 0.55 x 109 spermatozoa mL-1; the highest percentage of viability 94.19 ± 1.42 % was obtained in males of two kilograms and the best motility with 86.00 ± 4.14 s in those of three kilograms. The variables presented differences (P ˂ 0.05) in relation to the weight. Considering the variables of the study, it is proposed to use two kilograms organisms to ensure fertilization, which will reduce operating costs.},
