In order to determine the growth and the state of fisheries of A. The growth was estimated using the general equation of von Bertalanffy, with prior application of the methods of Bhattacharya and Powell-Wetherall. Mortality and exploitation rate were determined using the inverse model of von Bertalanffy. For the biological samplings, a total of individuals of A. In the commercial samplings, individuals of A.

Pustulose Ark (Anadara tuberculosa) - Shell Valve Internal View

The SLFD was different between sexes for both species; females were larger than males. Subpopulations of A. The overall sex ratio was 2. Possibly, these results may be due to differential growth rate between sexes and environmental factors along the year.

Effect of mixed-Bacillus spp isolated from pustulose ark Anadara tuberculosa on growth, survival, viral prevalence and immune-related gene expression in shrimp Litopenaeus vannamei. The widespread overuse of antibiotics in aquaculture has led to the emergence of antibiotic-resistance shrimp pathogens, the negative impact on shrimp gut microbiota, and the presence of antimicrobial residues in aquaculture products, with negative consequences on human health. Alternatively, probiotics have positive effects on immunological responses and productive performance of aquatic animals. In this study, three probiotic bacteria, Bacillus licheniformis MAt32, B. The specific growth rate of shrimp was significantly higher in T2 than in T1 control treatment, and the final growth as well as the survival were similar among treated groups. The LvToll1 gene was significantly up-regulated in treatments T4 and T5 compared to control.
