TN249-10 - Lipofuscin and Euphausiid Aging
https://data.eol.ucar.edu/dataset/102.177

Summary
Age determination in crustaceans relies on quantification of a fluorescent age
pigment, lipofuscin, that accumulates in eye stalks of krill over time.
Lipofuscin includes a mixture of protein oxidation products formed in neural
tissues. The extracted products are quantified using a fluorescence detector.
The concentration of lipofuscin is normalized to the protein content from the
same tissues. The ratio of lipofuscin to protein concentration is the
Lipofuscin Index and is calculated for each individual organism. In order for
the index to reflect chronological age, a calibration is required using
euphausiids of known age. A comparison of the calculated ages to the specific
lengths for each krill provides the ages for those krill analyzed during each
cruise. These data were collected aboard the UNOLS R/V Thompson ship. Data
were collected during the Bering Sea Ecosystem Study-Bering Sea Integrated
Ecosystem Research Program (BEST-BSIERP). BEST-BSIERP together are the Bering
Sea project.
