First Metataxonomic Characterisation of Gut Microbiota of Swordfish (Xiphias gladius). [PDF]

Environ Microbiol Rep
This is the first metataxonomic characterisation of gut microbiota of swordfish using next‐generation sequencing. Findings show significant differences in the alpha diversity among the weight categories and the FAO fishing areas. The phylum Pseudomonadota dominated the swordfish gut microbiota, followed by Fusobacteriota. Photobacterium resulted in the

Portuguese commercial fisheries of swordfish, Xiphias gladius

Frontiers in Marine Science, 2014
Swordfish has an important role in Portuguese fisheries. Portuguese commercial swordfish landings were analyzed from 1986 to 2012. Commercial landings of five incidental catches of pelagic sharks (Alopias superciliosus, Alopias vulpinus, Isurus ...

Almost billfish: convergent longirostry, micro-dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy. [PDF]

J Anat
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Brain Morphology and Quantitative Assessment of Sensory Brain Areas in Southern Bluefin Tuna, Thunnus maccoyii (Scombridae, Teleostei). [PDF]

J Comp Neurol
The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...

Effects of Kudoa thyrsites on Proximate Composition and Texture of Merluccius capensis and Zues capensis. [PDF]

J Fish Dis
ABSTRACT Kudoa thyrsites is a myxosporean endoparasite that infects fish, frequently resulting in myoliquefaction, impacting the texture and eating quality of fish muscle. The aim of this study was to investigate the effects of K. thyrsites infection on the proximate composition and texture parameters of raw fillets from two South African economically ...

Environmental and human factors shape the trophic ecology of a widespread marine predator. [PDF]

J Anim Ecol
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Philichthys xiphiae (Copepoda; Philichthyidae) – an interesting cranium parasite of the swordfish Xiphias gladius collected from the Baltic Sea [PDF]

Oceanological and Hydrobiological Studies, 2021
Abstract The swordfish, Xiphias gladius Linnaeus, 1758, is a fish that sporadically enters the Baltic Sea. The present paper describes the identification of a very rarely recorded and poorly studied copepod of the family Philichthyidae – Philichthys xiphiae Steenstrup, 1862 – in a dead swordfish found on a sea beach in Dźwirzyno (Poland)
