FOFS measurements and metabolic performance records for transplants and recruits of Mytilus spp. incubated using KOBs in summer 2018

These data were produced in two lab assays. The first assay was conducted in the period from August 29 to September 10, during which filtration and respiration of 18 mussels transplanted and grown for ca. four months under thermal history levels of + 0 °C and + 4 °C (using Kiel Outdoor Benthocosms, KOBs) were recorded in six temporally replicated (independent) trials using the Fluorometer and Oximeter-equipped Flow-through Setup (FOFS; Vajedsamiei et al., 2021). In each trial, filtration and respiration of three different transplants, randomly selected from the incubated samples were recorded in response to a constant mild temperature condition (20.8 °C) followed by two 24 h thermal fluctuation cycles. In the second assay, we recorded filtration and respiration rates of six batches of 5 or 6 mussels recruited and grown under the same thermal history levels in KOBs (three batches from each thermal history level) in temporally replicated trials of the same FOFS treatment, as explained earlier.
