“…The sagitta otoliths and cephalopod beaks were identified to the lowest possible taxonomic level using a stereomicroscope, a reference otolith collection of fish collected in the study area, and published catalogues (Corrêa & Vianna, 1992/93; Lemos et al ., 1992/93, 1995 a , 1995 b ; Vaske-Junior, 2006; Rossi-Wongtschowski et al ., 2014; Siliprandi et al ., 2016; Santificetur et al ., 2017). Otoliths and beaks were then classified into two categories each: right or left otoliths and lower or upper beaks.…”

This study evaluated the feeding habits of the franciscana dolphin (Pontoporia blainvillei) in south-eastern Brazil. Stomach contents were collected from a total of 145 dead specimens found incidentally caught by fishing vessels or stranded between 2005 and 2015. Fish otoliths, cephalopod beaks and whole non-digested prey were used for prey species identification. A total of 9337 prey items were identified, including 26 species of teleost fishes and three species of cephalopods. The most important prey families were Sciaenidae among fish and Loliginidae among cephalopods. Franciscana dolphins tended to feed on small fish (mean = 5.25 cm) and cephalopods (mean = 8.57 cm). The index of relative importance (IRI) showed that Pellona harroweri and Doryteuthis plei were the most important prey for both males and females. The PERMANOVA test confirmed that there is no significant difference between the feeding habits of different sexes, but detected a significant difference among seasons. Overall, our results show that franciscana dolphins are predominantly ichthyophagous and non-selective in relation to the type of prey, feeding on pelagic, demersal and pelagic-demersal prey.

“…Sediment in the 2 mm and 500 μm fractions was carefully scanned under a dissecting microscope and all otoliths picked from the carbonate sands. Each isolated otolith was identified using regional literature [35–38], established databases (https://otolithspisciumpanama.jimdo.com/) [39] and our specially-built in-house reference collection (see below). Identifications made to the highest taxonomic resolution confidently possible, although all identifications conservative.…”

Reconstructing reef fish communities using fish otoliths in coral reef sediments

et al. 2019

Little is known about long-term changes in coral reef fish communities. Here we present a new technique that leverages fish otoliths in reef sediments to reconstruct coral reef fish communities. We found over 5,400 otoliths in 169 modern and mid-Holocene bulk samples from Caribbean Panama and Dominican Republic mid-Holocene and modern reefs, demonstrating otoliths are abundant in reef sediments. With a specially-built reference collection, we were able to assign over 4,400 otoliths to one of 56 taxa (35 families) though mostly at genus and family level. Many otoliths were from juvenile fishes for which identification is challenging. Richness (by rarefaction) of otolith assemblages was slightly higher in modern than mid-Holocene reefs, but further analyses are required to elucidate the underlying causes. We compared the living fish communities, sampled using icthyocide, with the sediment otolith assemblages on four reefs finding the otolith assemblages faithfully capture the general composition of the living fish communities. Radiocarbon dating performed directly on the otoliths suggests that relatively little mixing of sediment layers particularly on actively accreting branching coral reefs. All otolith assemblages were strongly dominated by small, fast-turnover fish taxa and juvenile individuals, and our exploration on taxonomy, functional ecology and taphonomy lead us to the conclusion that intense predation is likely the most important process for otolith accumulation in reef sediments. We conclude that otolith assemblages in modern and fossil reef sediments can provide a powerful tool to explore ecological changes in reef fish communities over time and space.

“…Although the combtooth blennies are easily distinguished from other blennies; however, there have been challenging debates regarding the classification within the Blenniidae (Lin & Hastings, 2013). Despite the several morphological and molecular studies (Almada et al., 2005; Bath, 2001; Hundt et al., 2014; Lin & Hastings, 2013; Mehraban et al., 2020; Springer, 1968, 1993; Springer & Williams, 1994), the morphological studies using their otoliths are scarce (Furlani et al., 2007; Rivaton & Bourret, 1999; Santificetur et al., 2017), especially from the western Indo‐Pacific region including the Persian Gulf and Oman/Makran Sea e ecoregions.…”

Hidden taxonomic characters in otoliths of blenniid fishes (Teleostei: Blenniidae) from the Iranian coasts of the Persian Gulf and Oman Sea ecoregions: A scanning electron microscopy approach

et al. 2021

View full text Add to dashboard Cite

In the present work, the morphological characteristics of sagitta were described and analysed for 10 species of combtooth blennies (Blenniidae) inhabiting the intertidal region of the Persian Gulf and Makran zone of Oman Sea to see the taxonomic usefulness of otoliths, especially their hidden characters for species identification. Based on the obtained results, sagitta morphology could be considered as diagnostic characters distinguishing the genera Alticus, Antennablennius, Istiblennius, Omobranchus and Parablennius showing differences related to general shape, that is, elliptic/oval to triangular; shape of antirostrum and its degree of development; the degrees of convexity of ventral and dorsal margins, and shape of ostium. The common/general otolith characters shared in the all studied combtooth blennies, is the heterosulcoid condition, which is a shared character with Perciformes and Gobiiformes. The type of sulcus is ostial, and it can be considered as a plesiomorph character shared with a basal group of actinopterygian fishes. The obtained results could be useful in taxonomical, paleontological, ecological and food and feeding habits studies.
