Abstract:
This dataset contains morphological stomach content data of the demersal flatfish Buglossidium luteum (solenette) collected at multiple sampling stations in the German Bight. At each station, B. luteum individuals were sampled during daytime using an epibenthic dredge (1 m width, 1 cm mesh size) towed for 5 minutes. Immediately after capture, fish were individually sealed in storage bags and frozen at −80 °C to preserve gut contents. In the laboratory, specimens were transferred to freezers and stored at −28 °C until further processing. Selected fish were defrosted and stomachs were removed and weighed. All prey items were sorted and identified to the lowest possible taxonomic level using a stereomicroscope (Leica MZ12), based on regional identification keys, taxonomic catalogues, expert consultation, and comparisons with fresh reference material. Occasionally, digestion and mastication of individuals resulted in the loss of diagnostic features. In those cases, individuals were determined at a higher taxonomic level. All taxa were quantified in terms of abundance and biomass (wet mass; measured to 0.0001g) within the stomachs, and stored in 70% ethanol. Following analysis, prey items were preserved in 70% ethanol. The stomach content dataset was curated by excluding foraminifera, nematodes, and parasites.
