Litopenaeus vannamei was divided into seven groups (defined as diets A0–A6) and fed with diets respectively containing 0, 0.5, 1, 2, 4 and 8 g/kg Yarrowia lipolytica (astaxanthin content: 1.5%) and 3 g/kg Haematococcus pluvialis (astaxanthin content: 2%). After an eight-week feeding trial, the results reflected that different levels of Y. lipolytica and H. pluvialis could significantly increase the weight gain rate of L. vanna...

Single-cell proteins are attracting growing attention as viable alternatives for fishmeal (FM) in aquatic feed. Methanotroph ( Methylococcus capsulatus , Bath) bacteria meal FeedKind ® (FK) is a type of single cell protein with high protein content (75.14%) and desirable amino acids profile, produced by Methylococcus capsulatus (Bath) living on methane consumption. The present study evaluated the potential of replacing FM with...
