Objectives: To study the various linear and non-linear relationships among variables of siboga squid Uroteuthis (photololigo) sibogae (Adam, 1954) from South East Coast India August to November 2021. Methods: Samples were measured nearest value 1.0mm weight was 1gm. Findings: Females had a mean DML 120 mm, whereas males 129 mm. The total pooled sexes 38.9 gm with female being 35.9 male 41.8 gm....

Luminescent bacteria in the family Vibrionaceae (Bacteria: γ-Proteobacteria) are commonly found in complex, bilobed light organs of sepiolid and loliginid squids. Although morphology of these organs in both families of squid is similar, the species of bacteria that inhabit each host has yet to be verified. We utilized sequences of 16S ribosomal RNA, luciferase α-subunit (luxA) and the glycerald...

Noctiluca scintillans, a heterotrophic unarmored unicellular bioluminescent dinoflagellate, occurs widely in the oceans, often as a bloom. Molecular phylogenetic analysis based on 18S ribosomal DNA sequences consistently has placed this species on the basal branch of dinoflagellates. Here, we report that the structural organization of its luciferase gene is strikingly different from that of the...

Aquatic animals are important to health-conscious consumers due to their high content of polyunsaturated fatty acids (PUFA) particularly omega-3 FA. This paper reports the fat contents and fatty acid profiles of 20 species of marine fish and 6 species of squid and shrimp (obtained in the fishing port of Pattani, Thailand), in addition to 7 types of Thai freshwater fish to create a fatty acid da...

Cephalopods are ecologically and economically important marine groups in the world. Biodiversity description is essential for sustainable utilization of natural resources to characterize biological entities conservation. DNA barcoding an effective tool used identification organisms at species level been widely delineate several ambiguity species. In this study, partial sequence mitochondrial cy...

The toxicity of Cnidaria is a subject of concern due to its influence on humans. In particular, jellyfish blooms can highly affect human economical activities, such as bathing, fishery, tourism, etc., as well as the public health. Stinging structures of Cnidaria (nematocysts) produce remarkable effects on human skin, such as erythema, swelling, burning and vesicles, and at times further severe ...

The Pearl River Estuary (PRE) is one of the major fishing grounds for squid Uroteuthis chinensis. Taking that into consideration, this study analyzes environmental effects on spatiotemporal variability U. chinensis in PRE, basis Generalized Additive Model (GAM) and Clustering Fishing Tactics (CFT), using satellite situ observations. Results show 63.1% total variation Catch Per Unit Effort (CPUE...
