metadata.value: Proper diet is critical for laboratory-reared animals, as it may affect not only
  their welfare, but also experimental results. Amphipods (Crustacea: Amphipoda)
  play important roles in ecosystems and are often used in environmental
  research. Endemic amphipods from the ancient Lake Baikal are promising for
  laboratory bioassays; however, there are currently no laboratory cultures. In
  this work, we determine how different diets affect the color and metabolism
  of a laboratory-reared Baikal amphipod, Eulimnogammarus cyaneus. We found
  that in freshly collected blue-colored animals, body color correlated with total
  carotenoid content. Total carotenoid levels did not differ after long-term
  (two months) feeding with a close to natural carotenoid-enriched, or even a
  carotenoid-depleted diet. Nevertheless, antennae color was closer to red in the
  natural-like diet group. It is likely that the carotenoids from the commercial
  diet are not properly metabolized in E. cyaneus. The animals fed commercial
  diets had a higher glycogen content, which may signify a higher metabolic rate.
  Overall, we show that a carotenoid-enriched diet optimized for decapods is not
  optimal for amphipods, likely due to different carotenoid compositions, and the
  diet for long-term rearing of E. cyaneus and other Baikal amphipods requires
  supplementation.
