Iron Age and Roman Salt Making in the Thames Estuary

Assemblage, 2019

Previous research on the Iron Age in Britain has argued that no fishing occurred during this period in Britain. This argument has now been complicated by large assemblages of fish bones that have been excavated from Iron Age sites in the Northern Isles. Further investigation into this issue became the focus of the author's MSc dissertation research in 2016, specifically on the recently excavated fish bone assemblages from the site of Swandro on Rousay, Orkney. Analytical methods, including stable isotope analysis and scanning electron microscopy, were applied in an attempt to determine how the fish may have been utilised at the site. Results have revealed evidence that could be interpreted as fishing activity and possible consumption by humans at Swandro. This paper disseminates and further examines these results and considers how this particular project is useful as a pilot study in the application of analytical methodologies to problematic faunal remains such as fish, and why this could be important to future zooarchaeological and environmental archaeological research.

Cambridge. This small assemblage comprises sieved and hand collected material from the 14 th and 16 th centuries. Results indicated a reliance on herrings and eels, with a variety of freshwater and marine remains found. Species diversity increased through time, indicating a wider range of marine habitats were becoming exploited. Cod and marine cod family fish were only found in any quantity in the 16 th century, when they were eaten both fresh and as traded, preserved fish. Overall, a surprisingly high quantity of freshwater fish was consumed; this may be related to site status. Declining quantities of burbot through time may point to an increase in pollution levels in local freshwater river systems.

In this volume of Trabalhos do LARC we present the Program and Abstracts of the 18th biennial meeting of the International Council for Archaeozoology Fish Remains Working Group (ICAZ-FRWG), hosted by the Directorate-General for Cultural Heritage Archaeosciences Laboratory (DGPC LARC) and the Research Centre in Biodiversity and Genetic Resources – Environmental Archaeology Research Group (CIBIO EnvArch). The meeting is aimed primarily for archaeozoologists interested in the systematic study of fish bones retrieved from archaeological sites around the world, and also to archaeologists, ichthyologists, historians, ethnographers, and fishery biologists. To this end the conference is structured to encompass a multiplicity of approaches to the study of fish remains and their contribution to our understanding of how fishing, fish trade, fish consumption, biodiversity, ecology and human impact on aquatic environments have changed through time.

Fish remains from a mid-2nd century AD context at Tienen (Belgium) are believed to represent the remains of a fish sauce produced in northern Gaul. The observed species spectrum, the reconstructed sizes of the fish, and modern data on the abundance, geographical distribution and size of fish in the surf zone of the Belgian coast and in the estuary of the Scheldt basin, together indicate that the species present in the sauce were captured in the upper reaches of an estuary. Using similar reference data it was also possible to establish that the fish were caught during spring or early summer. After a discussion of the possible fish catching methods used in estuaries during Roman times, the assemblage from Tienen is compared to other Roman finds of locally produced fish sauce that have been reported thus far from sites in Great Britain and Belgium.

This contribution directly relates to the paper published by Wheeler in 1978 entitled 'Why were there no fish remains at Star Carr?'. Star Carr is arguably the richest, most studied and re-interpreted Mesolithic site in Europe but the lack of fish remains has continued to vex scholars. Judging from other materials, the preservation conditions at the site in the late 1940s/early 1950s should have been good enough to permit the survival of fish remains , and particularly dentaries of the northern pike (Esox lucius L., 1758) as found on other European sites of this age. The lack of evidence has therefore been attributed to a paucity of fish in the lake. However, new research has provided multiple lines of evidence, which not only demonstrate the presence of fish, but also provide evidence for the species present, data on how and where fish were being processed on site, and interpretations for the fishing methods that might have been used. This study demonstrates that an integrated approach using a range of methods at landscape, site and microscopic scales of analysis can elucidate such questions. In addition, it demonstrates that in future studies, even in cases where physical remains are lacking, forensic techniques hold significant potential.

The growth increments were investigated of late medieval, post-medieval and modern otoliths of plaice, cod and haddock from the North Sea. Thin-sectioned otoliths were used to age all the analysed individuals and to reconstruct their growth patterns. In addition, fish lengths of the archaeological specimens were calculated after the relation between otolith width and fish length was established using modern material. The age and fish length distribution, and the growth patterns obtained on the archaeological material allow inferences about fish trade, market strategies and consumption behaviour on producer sites (coastal sites) and consumer sites. Differences in growth patterns were observed between the archaeological and recent populations of the three demersal species analysed which may be related to a change in fishing pressure through time. However, diachronic changes in species distribution, temperature, food availability and selection of catch in function of market strategies may have played a role as well. Age and body size data allow some inferences about the exploited fishing grounds, but the growth patterns are of limited use in this respect.

The absence of fish remains in archaeological sites in Moreton Bay, southeast Queensland, Australia, may be a function of recovery techniques, rather than a reflection of resource paucity and late onset of occupation, as has been posited in archaeological literature. An excavation on Peel Island in Moreton Bay was devised, in part, to test this proposition, and a 1-mm mesh screen was used to enhance recovery. But sorting this fine fraction took 20 h. In this article we outline experiments to find a more efficient and effective technique for sieving and sorting fine fraction archaeological deposits, using methods borrowed from soil science. We show how sorting time can be reduced to 2 h 30 min per 100 g sample and argue that the vast increase in knowledge about the site occurring as a result of using the very fine mesh sieve warrants the continued application of these laboratory methods.

Fish represent a key economic, social and ecological group of species that humans have exploited for tens of thousands of years. However, as many fish stocks are going into decline and with little known about the anthropogenic impacts on the health of the marine ecosystem pre-Industrial Revolution, understanding historical and archaeological exploitation of fish species is key to accurately modelling these changes. Here, we explore the potential of collagen peptide mass fingerprinting (also known as Zooarchaeology by Mass Spectrometry, or ZooMS) for identifying fish remains from the Medieval (fifteenth century) Newport ship wreck (Wales, UK), and in doing so we establish a set of biomarkers we consider useful in discriminating between European fish taxa through the inclusion of over 50 reference taxa. The archaeological results identified nine distinct taxonomic groups, dominated by ling (> 40%), and a substantial amount of cod (> 20%) and hake (~ 20%). The vast majority of samples (> 70%) were identified to species level, and the inability to identify the remaining taxonomic groups with confidence using ZooMS was due to the fact that the reference collection, despite being relatively large in comparison to those presented in mammalian studies, reflects only a small proportion of fish biodiversity from this region. Although the results clearly demonstrate the potential for ZooMS as a means of fish bone identification, the sheer number of different fish species that potentially make up ichthyoarchaeological assemblages leads to obvious requirements for the analysis on much greater numbers of modern reference specimens, or the acquisition of collagen sequences.
