 The use of medicinal plants is proposed in the treatment of diseases that impact aquaculture because they synthesize and accumulate physiologically active substances that promote pathogen inhibition (antimicrobial, antioxidants, etc.). For this reason, the goal will be to evaluate the concentration and inhibitory capacity of phytochemical compounds in plant extracts of Randia echinocarpa and the survival of fish infected with streptococci.

 The plant was collected in the municipality of Badiraguato, Sinaloa, in the community of Rancho Viejo, and was later taken to the laboratory. Processing of plant tissues (unripe and ripe fruit, leaf, peel, fruit peel) of R. echinocarpa for use in tilapia feed supplementation.

All tissues were crushed, placed in trays, and dried by freeze-drying (LABCONCO), in ovens  at 45 and 75°C (Yamato IC403CW).

 Total lipids were analyzed in five tissues of R. echinocarpa in two seasons of the year with three drying variations (Freeze-dried, Oven 45 and 75 °C).

 A higher concentration of lipids was determined in the ripe and  unripe fruit. Finding higher concentrations of lipids in ripe fruit dried at 75 °C both in autumn and winter, being significantly higher.

  Likewise, the soil was analyzed in the four seasons of the year to know the properties where R. echinocarpa develops. An increase in phosphorus and nitrates was found in spring and phosphorus in summer.
