| The following research isolated and identified the main bacterial groups present in the culture of juvenile Nile tilapia in the presence of bioflocs and/or periphyton. The strains were also tested for the production of exoenzymes, indicative of potential virulence factors, and ability to form biofilm. The water samples were taken from tilapia cultured in the presence of bioflocs (T1), in the presence of bioflocs and periphyton (T2), from traditional culture (T3) and from culture in the presence of periphyton (T4). In the growth and selection of the bacterial groups, pour plate method was used, along with the following media: Plate Count Agar (PCA - DIFCO), Aero Pseudo Selective Agar (GSP - Himedia) and Nutrient Agar (AN - Merck). 46 strains were isolated... |

| Evaluation of semen characteristics after hormonal induction of the bullfrog could provide valuable information on the gametes of this species, which may be useful for projects related to artificial fertilization, animal improvement, and cryopreservation. Bullfrog males were induced to spermiate with buserelin acetate (GnRHa), and their semen was subsequently analyzed. GnRHa (0.4 μg) was administered to the bullfrog males with secondary sexual characteristics such as weight > 200 g, yellow chin, nuptial callus, and amplexus reflex, being the semen collected after 60 min. The semen volume was 5.76 mL, light-colored. The other characteristics of the semen were: vigor of 4.80, motility of 93%, concentration of 14.24 × 106 mL-1, and content of normal... |
