Body length estimation of the European eel Anguilla anguilla on the basis of isolated skeletal elements

  title={Body length estimation of the European eel Anguilla anguilla on the basis of isolated skeletal elements},
  author={Els Thieren and Wim Wouters and Wim Van Neer and Anton Ervynck},
using a large series of dry skeletons of modern European eel Anguilla anguilla (Linnaeus, 1758) from Belgium and the Netherlands, the relationship between fish length and individual bone measurements is investigated. The aim of the study is to provide adequate regression equations between both parameters. This methodology is relevant for both palaeoecological and ecological researches since isolated skeletal elements survive in large numbers on archaeologi- cal sites and in the stomach contents… Expand
Estimation of fish size from archaeological bones of hardhead catfishes (Ariopsis felis): Assessing pre-Hispanic fish acquisition of two Mayan sites
The application of the osteometric results provides an assessment of the contribution of fish to the economy and permits the identification of fishing methods from two Mayan settlements from the Classic to Postclassic periods. Expand
Neolithic fish remains from the freshwater shell midden Riņņukalns in northern Latvia
The Neolithic site Riņņukalns in the Lake Burtnieks/River Salaca area in northern Latvia is the only freshwater shell midden in the eastern Baltic Sea area. An excavation carried out in 2011 revealedExpand
Bone resorption and body reorganization during maturation induce maternal transfer of toxic metals in anguillid eels
This study provides analytical evidence for the maternal transfer of toxic metals from soft and hard tissues to the ovaries of mature females and suggests a physiologically connected interplay of energy metabolism and bone resorption in the reproductive strategy of eels. Expand
Fishing for ways to thrive: Integrating zooarchaeology to understand subsistence strategies and their implications among Early and Middle Mesolithic southern Scandinavian foragers
The purpose of this thesis is to evaluate and deduce the varied lifeways of Early Holocene foragers in southern Scandinavia. By taking an interdisciplinary approach, zooarchaeological data have beenExpand
Assessing the Radiocarbon Freshwater Reservoir Effect for a Northwest-European River System (the Schelde Basin, Belgium)
ABSTRACT The freshwater reservoir effect (FRE) for the Schelde basin (Belgium) is assessed for the Roman, Medieval and early Post-medieval periods by comparing historical and archaeological datesExpand
New Equations for the Size Reconstruction of Sturgeon from Isolated Cranial and Pectoral Girdle Bones
Differentcurve variations (power,linear,logarithmic andexponential) were modeled and applied toarchaeologicalsturgeonremains(A.sturio/A.oxyrinchus) fromVlaardingen,aDutchlateNeolithicsettlement, allowing back-calculation of sizefromisolated sturgeon remains. Expand
Late Pleistocene-Holocene coastal adaptation in central Mediterranean: Snapshots from Grotta d’Oriente (NW Sicily)
Marine faunal remains from Grotta d’Oriente (Favignana Island, NW Sicily) offer invaluable snapshots of human-coastal environment interaction in the central Mediterranean from the Late Pleistocene toExpand
Scutes for sturgeon size reconstruction: traditional and geometric morphometric techniques applied to Acipenser sturio and A. oxyrinchus
It is concluded that isolated scutes cannot provide very accurate fish length reconstructions and different scute measurements was tested with linear regressions using 58 modern sturgeons from museum collections. Expand
Fish in the desert: Identifying fish trade routes and the role of Red Sea parrotfish (Scaridae) during the Byzantine and Early Islamic periods
Abstract Recent archaeological excavations in the Negev desert of the southern Levant have yielded a surprising and unprecedented amount of fish remains, found in the landfills at Byzantine (4th–7thExpand
Archaeology as a Tool for Understanding Past Marine Resource Use and Its Impact
As the study of material traces of past human activity, archaeology straddles the sciences and humanities. Alongside time depth, often stretching back thousands of years, it is this intersectionExpand


Errors associated with otter Lutra lutra faecal analysis. II. Estimating prey size distribution from bones recovered in spraints
These methods involve modelling the size-related differential recovery of key fish bones recovered in faeces (spraints) and avoid two sources of errors that may have occurred using previous techniques which relied solely on a series of correlations between fish length and the length of individual vertebrae.

Differences in head shape of the European eel, Anguilla anguilla (L.)
Differences in eel, Anguilla anguilla (L.), head shape were the result of greater increases in head width, rather than changes in head length, which may have resulted from diet. Expand
The use of fish vertebrae in scats for estimating prey size of otters and mink
Comparison of direct length measurements of fish fed to captive mink with length estimates obtained from vertebrae recovered in then scats and derived using the appropriate regression lines determined from the reference fish revealed a close measure of agreement and indicated that the method achieves a high level of accuracy. Expand
Bimodality in head shape in European eel
Biometric data support the hypothesis that a head shape variation in ‘Belgian’ European eel is best described as having a bimodal distribution and suggest that this may be the result of phenotypic plasticity related to trophic segregation between morphs. Expand
Fish Otoliths in Cetacean Stomachs and Their Importance in Interpreting Feeding Habits
The stomachs of 17 cetaceans of seven species yielded 18,164 fish otoliths representing over 51 species, 40 genera, and 22 families, and it is indicated that they routinely forage in depths of 650–800 ft (200–250 m), and a few such as Kogia simus may descend to 1000‴ft (300‴m) or deeper. Expand
Biometric data to facilitate the diet reconstruction of piscivorous fauna
Biometric data enable the lengths and weights of fish in the diet of piscivorous fauna to be estimated from measurements of bones and scales that are recovered from faeces and stomach contents, and were demonstrated by reconstructing the length composition of species in the diets of cormorants and otters.

Fishing in Denmark during the Ertebølle periodxs
Fishing in Denmark during the Ertebolle period is discussed on the basis of almost 100000 identified fishbones from 14 coastal and two inland settlements. Forty-one fish species were identified fromExpand
Stomach contents analysis—a review of methods and their application
Methods for analysing fish stomach contents are listed and critically assessed with a view to their suitability for determining dietary importance and the best measure of dietary importance is proposed as one where both the amount and bulk of a food category are recorded. Expand
