    This article documents, shows and analyses the everyday rhythms of Billingsgate, London’s wholesale fish market. It takes the form of a short film based an audio-visual montage of time-lapse photography and sound recordings, and a textual account of the dimensions of market life revealed by this montage. Inspired by Henri Lefebvre’s Rhythmanalysis, and the embodied experience of moving through and sensing the market, the film renders the elusive quality of the market and the work that takes place within it to make it happen. The composite of audio-visual recordings immerses viewers in the space and atmosphere of the market and allows us to perceive and analyse rhythms, patterns, flows, interactions, temporalities and interconnections of market work, themes that this article discusses. The film is thereby both a means of showing market life and an analytic tool for making sense of it. This article critically considers the documentation, evocation and analysis of time and space in this way

    Higher heritabilities for gait components than for overall gait scores may improve mobility in ducks

    International audienceAbstractBackgroundGenetic progress in selection for greater body mass and meat yield in poultry has been associated with an increase in gait problems which are detrimental to productivity and welfare. The incidence of suboptimal gait in breeding flocks is controlled through the use of a visual gait score, which is a subjective assessment of walking ability of each bird. The subjective nature of the visual gait score has led to concerns over its effectiveness in reducing the incidence of suboptimal gait in poultry through breeding. The aims of this study were to assess the reliability of the current visual gait scoring system in ducks and to develop a more objective method to select for better gait.ResultsExperienced gait scorers assessed short video clips of walking ducks to estimate the reliability of the current visual gait scoring system. Kendall’s coefficients of concordance between and within observers were estimated at 0.49 and 0.75, respectively. In order to develop a more objective scoring system, gait components were visually scored on more than 4000 pedigreed Pekin ducks and genetic parameters were estimated for these components. Gait components, which are a more objective measure, had heritabilities that were as good as, or better than, those of the overall visual gait score.ConclusionsMeasurement of gait components is simpler and therefore more objective than the standard visual gait score. The recording of gait components can potentially be automated, which may increase accuracy further and may improve heritability estimates. Genetic correlations were generally low, which suggests that it is possible to use gait components to select for an overall improvement in both economic traits and gait as part of a balanced breeding programme

    Perch use by laying hens in a commercial aviary

    Non-cage housing systems, such as the aviary, are being implemented by the laying hen industry, including in North America, in an attempt to improve the welfare of hens. Perches are a resource that is consistently included in aviaries. Hens are strongly motivated to perch, and perching can improve leg bone strength. However, hens may prefer elevated perches, particularly at night, and thus simply providing perches is not enough to improve welfare; they must be provided in a way that allows all hens to access them. Observations of laying hens using perches and ledges (flat, solid metal shelves to assist hens' movement between tiers) in a commercial aviary revealed variation in where hens roosted within the tiered aviary enclosure across the flock cycle (peak, mid and end of lay; P P P

    Fishmongers in a global economy: craft and social relations on a London market

    This article is based on multi-sensory ethnographic research into fishmongers on a south London market, the setting for a specific topography of work. We contrast Charlie, a white Londoner whose family has been in the fish business for over 100 years, with Khalid, an immigrant from Kashmir, who, even without the tacit knowledge of generations at his fingertips, has successfully found a place for himself in the local and global economy of fish. The research pays attention to the everyday forms of work that take place when the fishmongers sell to the public. We use these two very different cases to explore what constitutes work and labour and the different sensibilities that these two men bring to their trade. Drawing on observations, photography and sound recordings, the paper also represents the fishmongers at work. We take the two cases in turn to discuss learning the trade and the craft of fishmongering, the social relations of the market, and the art of buying and selling fish. More generally, the article explores how global connections are threaded through the local economy within a landscape of increasing cultural and racial diversity. It also critically discusses the gain of the visual as well as the aural for generating insights into and representing the sensuous quality of labour as an embodied practice
