The changes in the molecular weight profiles and biochemical compositions of potential feed ingredients for sustainable aquaculture

The objective of study was to evaluate the differences in the molecular weight profiles and the biochemical compositions of potential feed ingredients such as fish meal (FM), Artemia nauplii (ArtN), Artemia metanauplii (ArtMn), copepod meal (CopM), dry Daphnia sp. (dryD), Daphnia magna (freshD) and...

description The objective of study was to evaluate the differences in the molecular weight profiles and the biochemical compositions of potential feed ingredients such as fish meal (FM), Artemia nauplii (ArtN), Artemia metanauplii (ArtMn), copepod meal (CopM), dry Daphnia sp. (dryD), Daphnia magna (freshD) and Tubifex. The lowest and highest ash (ArtN 5.84±0.05%, 45.18±1.17% dryD) lipid (dryD 4.71±0.06%, ArtN 30.19±0.65%) and protein contents (45.45±3.90% freshD, 66.74±0.2% CopM) were detected (p= Da and 2532-13000 Da, respectively. The highest molecular weight profile belongs to 67000= Da molecular weight.
