Effect of Blood Orange ( L. Osbeck) Peel Waste as a Feed Additive on the Growth Performance, Digestive Enzyme Activity, Antioxidant Capacity, and Immune Response in Juvenile Black Rockfish ().

This study evaluated bioactive compounds in blood orange ( (L.) Osbeck) peel (BOP) as dietary additives. An 8-week feeding trial was conducted to investigate the effects of dietary supplementation on the growth performance, body composition, digestive enzyme activity, antioxidant capacity, and immune response of juvenile black rockfish.

Evaluation of Garlic Juice Processing Waste Supplementation in Juvenile Black Rockfish () Diets on Growth Performance, Antioxidant and Digestive Enzyme Activity, Growth- and Antioxidant-Related Gene Expression, and Disease Resistance against .

An 8-week feeding trial was conducted to evaluate the effects of various dietary levels of garlic juice processing waste (GJPW) on the growth, feed utilization, digestive and antioxidant enzyme activity, growth- and antioxidant-related gene expression, and resistance to infection of juvenile black rockfish (). A total of 450 juvenile rockfish were randomly distributed into 30 L rectangular tanks (30 fish per tank). Five experimental diets were prepared in triplicate.

Dietary Supplementation with Ginger () Residue from Juice Extraction Improves Juvenile Black Rockfish () Growth Performance, Antioxidant Enzyme Activity and Resistance to Infection.

Plant-derived feed additives provide cost effective and environmentally friendly alternatives to antibiotics for improving fish performance in aquaculture. An 8-week feeding trial was conducted to evaluate the effects of dietary ginger residue from juice extraction (GRJE) on juvenile black rockfish () growth performance, antioxidant enzyme activities, and resistance to Streptococcus iniae infection. Juvenile rockfish ( = 450; initial weight = 2.
