ABSTRACT. Jellyfish (JF) are essential to marine ecosystems. However, JF that increases rapidly can have negative effects. On 3-4 August 2022, a significant JF (Lobonemoides robustus Stiasny, 1920) bloom was observed along Cox’s Bazar coast (from Najdirartek to Sabrang) in Bangladesh. The goal of the current investigation was to identify the fatty acids (FAs) and amino acids (AAs) of L. robustus. The AAs were determined using liquid chromatography–tandem mass spectrometry (LC-MS/MS) analysis, while the FAs were determined using a gas chromatographic system with a flame ionisation detector. The most prevalent AA was glycine. The most common FA was linoleic acid (C18:3) (0.43%), followed by myristic acid (0.12%), cis-9-oleic acid (0.18%), gamma-linolenic acid (0.24%), and heptadecanoic acid (0.29%). Based on its AA and FA contents, L. robustus can be a great candidate for the potentially sustainable manufacture of nutraceutical, cosmeceutical, and biomedical natural products to improve health and well-being. In addition, the edible L. robustus could be exported to other countries, thus way it can play a major role in achieving a blue economy.
