The experiment used twenty specimens in four stages of body growth (PI, PII, PIII and PIV) harvested every 90 days, containing five specimens, each group. The livers were dissected, weighed (g) and processed routinely using the hematoxylin and eosin technique. The data were submitted to analysis of variance, Pearson\u2019s correlation test and linear regression. The equation that represented the weight-length relation was W = 0.05902 x L2.63, with negative allometric growth, but with a relative condition factor equal to 1.0. The liver was divided into three lobes with the gallbladder close to the right lobe and its color varied from light red to dark red, not varying in relation to other fish species. The hepatosomatic relationship followed body growth until the PII group stage and then declined, demonstrating the behavior of its development in Brycon amazonicus. The organ consists predominantly of hepatocytes, followed by sinusoidal vessels and capillaries, with histological morphology similar to that of many species of fish. Melanomacrophage centers were found only in the most developed animals, but in small quantities, prompting the development of new research on this cell, in this species. In this way, research of this nature allows the characterization of fish species, helping to improve breeding methods, understanding pathological processes caused by diseases, and obtaining better productive capacity, serving an increasingly demanding and prosperous market.<\/jats:p>","DOI":"10.1590\/1519-6984.244784","type":"journal-article","created":{"date-parts":[[2021,6,29]],"date-time":"2021-06-29T00:40:41Z","timestamp":1624927241000},"source":"Crossref","is-referenced-by-count":0,"title":["Anatomical and histological traits of Brycon amazonicus liver cultivated in a semi-intensive system"],"prefix":"10.1590","volume":"83","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7198-8939","authenticated-orcid":false,"given":"H.
