The excess of circulating growth hormone (GH) in most transgenic animals implies mandatory growth resulting in higher metabolic demand. Considering that the intestine is the main organ responsible for the digestion, absorption, and direction of dietary nutrients to other tissues, this study aimed to investigate the mechanisms by which overexpression modulates the intestine to support higher growth. For this purpose, we designed an 8-weeks feeding trial to evaluate growth parameters, feed intake, and intestinal morphometric indices in the adult -transgenic zebrafish () model.

Embryos and larvae of M. mactroides were submitted and maintained at four different salinities: 20, 25, 30 and 35 ppt, to determine optimal conditions for the species.

- The yellow clam (Mesodesma mactroides) is crucial to the economy and ecology of Brazil, Uruguay, and Argentina, and understanding its reproductive biology is essential for species reestablishment.
- Laboratory studies on the clam revealed key stages of embryonic and larval development, including the timeline from fertilization to complete metamorphosis.
- Future research aims to develop a technological strategy to support the rearing and conservation of M. mactroides based on these findings.
