Effects of temperature and food availability were tested using a 6 x 4 factorial experimental design with six temperature treatments (10, 12, 14, 16, 18, 20°C) and four concentrations of Rhodomonas sp. microalgae (500, 2500, 5000, 10,000 cells mL-1) for a total of 24 treatment combinations. Food treatments represented algal concentrations from starvation to ad libitum conditions. Temperature and food treatments were based on historical observations of temperature trends and chlorophyll abundance. Larval samples were collected 4, 9, and 15 days post-fertilization and fixed in 10% PBS buffered formalin for morphometric analyses. \n\nSamples were collected before feeding to minimize influence of algae on stomach measurements. Fixed larvae were then photographed using an Olympus BX41 compound microscope with a Nikon 3400 DSLR camera at 4X magnification and postoral arm length, body length, stomach length and height were measured in 20 randomly selected larvae from each sample using ImageJ software (Schneider et al. 2012). Metamorphic competency was determined when >50% of larvae exhibited tube feet and adhered to the bottle.\n\ncdm_data_type = Other\nVARIABLES:\ndpf (days)\ntemp (degrees Celsius)\nfood (cells per mL)\nrep (unitless)\nindividual (unitless)\nPOA1 (µm)\nPOA2 (µm)\nBL (µm)\nSW (µm)\nSH (µm)\nPOA (µm)\nSA (µm2)\n https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_963425_v1/index.htmlTable https://osprey.bco-dmo.org/dataset/963425 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_963425_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_963425_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_963425_v1

Larval sampling was conducted every two days to estimate changes in larval density and competency, in conjunction with water changes and feedings. Larval densities were quantified by concentrating larval cultures to 100 mL and counting the number of larvae found in five 1 mL subsamples. Density counts continued until larvae showed signs of metamorphosis, as determined by the presence of a rudiment and exposed tube feet.\n\ncdm_data_type = Other\nVARIABLES:\ndate (unitless)\ntemp (degrees Celsius)\nfood (cells per mL)\nrep (unitless)\ncount (unitless)\ncount_value (unitless)\navg_count (unitless)\nvolume (mL)\navg_bottle (unitless)\nsample_day (days)\ndpf (days)\n https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_963422_v1/index.htmlTable https://osprey.bco-dmo.org/dataset/963422 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_963422_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_963422_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_963422_v1

To gather better empirical data we quantified winter growth and lipid accumulation in BSB juveniles from Long Island Sound using two complementing experiments. The data from Experiment 2 are presented here.\n\nThe data from Experiment 1 are presented in a related dataset (https://www.bco-dmo.org/dataset/897895). Experiment 2 measured the same traits as Experiment 1 but exposed juveniles to a simulated thermal overwinter profile (October - March) with seasonally varying food rations. Monthly individual length growth (GR) and weight-specific growth (SGR) responded in the direction of seasonal food level changes, showing reduced growth in December-February in a 'Winter dip' treatment, but compensatory growth in a 'Winter pulse' treatment. A 6-month consumption average of 1.7% feeding-1 ('Winter pulse') elicited a mean GR of 0.15 millimeters per day (mm d-1) and SGR of 0.55% d-1, whereas juveniles consuming on average 3.8% per feeding ('Winter dip') had significantly faster GR (0.20 mm d-1) and SGR (0.71% d-1). Growth efficiencies ranged between 15-30% and were inversely related to food consumption.\n\nIn both experiments, juveniles disproportionally accumulated lipid over lean mass, with lipid proportions tripling in Exp2 from 4% at 65 mm to 12% at 120 mm.\n\ncdm_data_type = Other\nVARIABLES:\nSite (unitless)\nlongitude (degrees_east)\nlatitude (degrees_north)\nDate_col (unitless)\nSpecies (unitless)\nTank (unitless)\nBSB_ID (unitless)\nGroup (unitless)\nTreat (unitless)\n...
