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.
