Title Benthic infauna from grab samples - Irish Sea
Downloaded 5 times
Description Abundance and biomass of benthic invertebrates from the Day grab samples per species and per station. Benthic invertebrates were sampled by taking six 0.1 m2 grabs at haphazard locations within the station box. All samples were sieved and preserved in 4% formalin for identification. All invertebrates were identified to the highest practicable taxonomic resolution (mostly genus or family) and the wet weight of species was estimated after blotting.

Title Otter trawl catches - Irish Sea
Downloaded 4 times
Description The catch composition of all species per trawl for the otter trawl catches. One or two tows of 30 min were carried out at each station with an otter trawl (distance across mouth of the net 16 m, 82 mm diamond mesh cod-end) at a speed of 3 knots between 06.00h and 17.00h. The total catch number and weight per species was measured.

Title D13C and D15N - Irish Sea
Downloaded 7 times
Description Stable isotope δ13C and δ15N signatures for Nephrops from the Irish Sea. White muscle tissue was extracted from the first tail segment with shell, digestive and nerve tract removed. Nephrop samples were stored frozen at -18°C after capture for later analysis in the laboratory. In the laboratory all tissue samples were oven dried for 24 hours at 75°C. Each individual tissue sample was ground to a homogenous powder using an agate pestle and mortar. Subsequently, 1.5-2.0 mg of the resulting powder was weighed into tin capsules for stable isotope analysis. Tissue samples were combusted for C and N isotope compositions using continuous flow isotope ratio mass spectrometry (CF-IRMS) THERMO delta X PLUS mass spectrometer (Scientific Technical Services - University of the Balearic Islands). The isotope mass spectrometer was operating in dual mode measuring δ15N and δ13C in the same sample Additionally C/N ratios are provided.

Title D13C and D15N - Kattegat
Downloaded 6 times
Description White muscle tissue samples from 5-6 individuals of each respective study species were collected for each station. For the flatfish, a 2 x 2 cm piece of white muscle tissue was taken with the skin removed approximately 2 cm to the right of the pectoral fin and 1 cm above the lateral line. For the Nephrops, white muscle tissue was extracted from the first tail segment with shell, digestive and nerve tract removed. Due to logistical constraints of the sampling, all samples from t were preserved in 100% pure ethanol for transport to the laboratory. In the laboratory all tissue samples were oven dried for 24 hours at 75°C. Each individual tissue sample was ground to a homogenous powder using an agate pestle and mortar. Subsequently, 1.5-2.0 mg of the resulting powder was weighed into tin capsules for stable isotope analysis. Tissue samples were combusted for C and N isotope compositions using continuous flow isotope ratio mass spectrometry (CF-IRMS) THERMO delta X PLUS mass spectrometer (Scientific Technical Services - University of the Balearic Islands). The isotope mass spectrometer was operating in dual mode measuring δ15N and δ13C in the same sample. Additionally C/N ratios are provided.

Description Nephrops norvegicus length and weight data that was used to estimate their condition. The carapace length and the total weight was measured, and their sex recorded. Futhermore if females carried eggs. Note that body weight is clawless weight.
