The effect of different fish feed compositions on ~d 13C and ~d 15N signatures of sea bass and its potential value for tracking mariculture-derived nutrients
Increasing demand for fish and seafood calls for an expansion of aquaculture production. At the same time, the status of the marine environment must not be jeopardised. Stable isotopes are potential markers for tracking feed-based nutrient flows from aquaculture into marine biota. Here, we demonstrate how four experimental diets (main protein components: fishmeal, soya
protein concentrate, wheat gluten, and Jatropha kernel meal) and a commercial diet induce characteristic ~d
