Aquaculture is an alternative method for the production of organisms for society; however, on occasions, this commercial activity is affected by the appearance of virus or bacteria in said organisms, diseases treated by the use of artificial chemicals, such as antibiotics, which may affect people’s health. Research is currently underway on alternative means, taken from natural medicine, of preventing viral and bacterial propagation in aquaculture production, including the present study, which was undertaken on a white leg shrimp (Litopenaeus vannamei) culture for eight weeks. The experimental design comprised seven fish tanks divided between two treatments containing fresh garlic at different concentrations and a control. The first treatment comprised 2.5 g garlic per kg of feedand the second comprised 5 g of garlic per kg, while the control treatment comprised commercial feed only. It should be noted that the first and second treatments were repeated twice. Treatments 1 and 3 presented 3% mortality, while 2% mortality was observed for Treatment 2,which presented the highest values for the length-weight correlation as well as the highest length and weight values.
