The aim of this work was to examine the effects of diets varying amount of lipids in zebrafish (danio rerio). The diets were: for control group a commercially available tropical fish diet (normal‐fat diet) and for the experimental group the same commercially available tropical fish diet plus crude vegetable oil (high‐fat diet). Two groups of adult young zebrafish (three‐month‐old zebrafish) were fed diets containing either normal‐fat diet or high‐fat diet and were tested during sixteen months. The control group (n=10) received 15 mg per fish of normal‐fat diet; a total meal for this group was 150 mg/day. The experimental group (n=10) received a total amount of 150 mg/day of normal‐fat diet plus 40 mg of crude vegetable oil (high‐fat diet). The size and weight were measured monthly in both groups. The mortality rate was not considerably influenced by dietary fatty acid composition throughout the period evaluated. The weight was highly affected by high‐fat diet after third month. No differences in the body size were observed between groups. Support or Funding Information This work was supported by Research Grant from the Pontificia Universidad Javeriana, Bogotá, Colombia.
