This paper presents a new feeding biological method for analysing prehistoric shellfishing material from Bronze Age tell at Tiszapolgár - Kenderföld. These values are used for determining whether the mussels served as a main or only a supplementary food source. This information may also reveal the approximate number of individuals the total meat could have provided for on the basis of the nutrition content of the soft material. In order to determine the live weight of the animals, along with the weight of their soft material or meat, and the derivable energy content, the main biometric parameters of the shells (shell height, shell width, the index of flatness = H/W, weight of the shells) should be recorded. These parameters, where possible, were captured with the help of a caliper at an accuracy of 0.5 mm. The weight of the shells was recorded using laboratory scales. The size and shape variants were used as an input into further analyses. Kiss (1990) has carried out detailed morphometric and population ecological investigations on living Unionidae from River Tisza in Hungary and found a strong correlation between the width of the shells and the live weight as well as the weight of the soft material via regression analysis. Where we could gain a measurement of shell widths, the species-dependent empirical formulae of Kiss (1990) were used to calculate the living weight and the derived meat of our studied mussels.
