Article Synopsis
- - Goiter, or enlargement of the thyroid gland, was observed in Brazilian basslets, a type of marine ornamental fish, in a research laboratory from 2016 to 2023, showing signs of tumor-like growths affecting feeding and respiration.
- - Around 20 adult fish developed these growths in the pharyngeal cavity and gill arches, resulting in severe health issues and eventual death within months after the growth appeared.
- - Histological analysis showed significant changes in thyroid cells, marking the first report of goiter in this species, and researchers recommend maintaining low nitrate levels and regular monitoring of iodine in water until more is known about the condition.
The study evaluated dietary supplementation with a feed additive composed of multi-strain Bacillus for Nile tilapia Oreochromis niloticus. In vitro and in vivo assays employing culture-based microbiological methods and metagenomics were performed. Additionally, the study assessed the haemato-immunology, intestinal microbiome, and growth performance of the animals.
