Effects of Pelleted and Extruded Feed on Growth Performance, Intestinal Histology and Microbiota of Juvenile Red Swamp Crayfish ().

The study was conducted to evaluate the extruded and pelleting feed production on growth performance, intestinal histology and microbiome analysis of juvenile red swamp crayfish, Procambarus clarkii. Crayfish were fed either pelleted or extruded feeds that were made using the same formula. Crayfish fed extruded feed had a lower feed conversion ratio, as well as significantly higher levels of trypsin and amylase (p < 0.

Dietary cholesterol-induced transcriptome differences in the intestine, hepatopancreas, and muscle of Oriental River prawn Macrobrachium nipponense.

Cholesterol is an important nutrient for crustaceans. In this study, we performed comparative transcriptome analyses to explore the transcriptome differences in the intestine, hepatopancreas, and muscle of Macrobrachium nipponense fed either a low cholesterol (LC) or high cholesterol (HC) diet (2.8 or 17.
