Detection of Anthropogenic Particles in Fish Stomachs: An Isolation Method Adapted to Identification by Raman Spectroscopy
TLDR
An extraction method based on hypochlorite digestion and isolation of MP from the membrane by sonication is presented, allowing better identification of anthropogenic particles (AP) from stomach contents of fish by Raman spectroscopy. Expand
Morphological comparison of the buccal apparatus in two bivalve commensal Teleostei, Encheliophis dubius and Onuxodon fowleri (Ophidiiformes, Carapidae)
TLDR
The E. dubius head morphology is more similar to the cephalic anatomy of non-bivalve commensal species than to O. fowleri, which could be indicative of how structure modifications and their influences on annex pieces could in part have a role in the biodiversity. Expand
Sound production mechanism in carapid fish: first example with a slow sonic muscle
TLDR
Carapid fishes produce sounds with a complex swimbladder mechanism, including skeletal components and extrinsic sonic muscle fibers with an exceptional helical myofibrillar structure, which is unique in animal sound generation. Expand
Microplastics in livers of European anchovies (Engraulis encrasicolus, L.).
TLDR
The presence of MPs in the livers of commercial zooplanktivorous fishes collected in the field is investigated and two translocation pathways are hypothesized: (i) large particles found in the liver resulted from the agglomeration of smaller pieces, and/or they simply pass through the intestinal barrier. Expand
Morphology of the filtration apparatus of three planktivorous fishes and relation with ingested anthropogenic particles.
TLDR
The morphology of the filtration apparatus of three wild-caught Clupeiformes and the results to ingested APs lead to the conclusion that the sardine is the species most exposed to APs. Expand
Trophic niches of thirteen damselfishes (Pomacentridae) at the Grand Récif of Toliara, Madagascar
TLDR
The trophic niches of 13 sympatric species of damselfishes are determined by combining stable isotope (δ15N and δ13C) and stomach content analyses, revealing that their choice of habitat on the reef and their behavior appear to be good predictors of diet in this group. Expand
Functional study of the pectoral spine stridulation mechanism in different mochokid catfishes
TLDR
Mochokidae are able to produce pectoral spine stridulation sounds and high speed videos were used to study the pECToral fin movements to identify the mechanisms involved. Expand
Environmental constraints drive the partitioning of the soundscape in fishes
TLDR
This first demonstration, to the authors' knowledge, of interference avoidance in a fish community can be understood by the way sounds are used, and it is demonstrated that sonic activity allows a clear distinction between a diurnal and a nocturnal group of fishes. Expand
Fish lateral system is required for accurate control of shoaling behaviour
TLDR
The lateral system is more crucial to shoaling behaviour than previously believed and should be considered a priority for further research. Expand
Early development of the head skeleton in Brycon moorei (Pisces, Ostariophysi, Characidae)
TLDR
The developmental pattern of B. moorei is extremely rapid in comparison with other teleosts, i.e. it prioritizes feeding structures that permit the expression of piscivory at a very early age and the uniqueness of this pattern is discussed in relation to ecological constraints on early feeding and fast growth.
