This study aimed to evaluate the effects of Ocimum basilicum supplementation in the diet for Piaractus mesopotamicus regarding productive performance, intestinal morphology, muscle residue, and hematological changes after simulated transport stress. Juvenile (23 g±0.08, n = 180) were stocked into 300-L tanks in three treatments and six replicates each: a control diet (not supplemented), a diet with 0.

- - Environmental enrichment in captivity is meant to improve the well-being of fish by simulating their natural habitat, but its effects on fish reproduction are not well understood.
- - In a study with twospot astyanax larvae, fish raised in enriched environments (with PVC pipes, stones, and plants) exhibited healthier reproductive structures compared to those in sterile environments.
- - Results indicated that sterile-reared fish showed early spawning and potential reproductive issues, leading to lower-quality offspring, whereas enriched fish had better-developed gametes and healthier larval outcomes.
The betta (Betta splendens) is a carnivorous ornamental species that requires live food. In this study, we evaluated the growth and survival of Betta splendens fingerlings fed ex-situ biofloc (BFT). A total of 375 fingerlings (8.

This study aimed to determine the growth patterns of juvenile piraputangas (Brycon hilarii) produced in hapas within an excavated pond. The piraputangas were anesthetized and micro-chipped and their biometric characteristics were measured.
