ABSTRACT
This chapter discusses the use of coriander, coriander oil, and extracts from coriander seed in fish feed and its effects on fish. An investigation demonstrated the effect of different botanical additives (mint, coriander, and amaranth leaves) on the growth and coloration of the ornamental goldfish. Adult goldfish fed at a 3% level exhibited a higher mean weight gain (1.939 g) and specific growth rate (0.668 g) compared to other coriander feeds. It was concluded that coriander had a constructive effect on the growth and coloration of ornamental goldfish. Research showed that fish fed with coriander had increased eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) concentrations. The study also demonstrated that adding coriander oil to diets could improve the fillet fatty acid composition of farmed fish. For eight weeks, a study was done to determine the effects of coriander seed extract on the physiological responses, immunity, and disease resistance of rainbow trout, Oncorhynchus mykiss. Studies have demonstrated that petroselinic acid in coriander seed oil has a positive impact on fish growth. The addition of petroselinic acid from coriander oil led to an increase in the anti-inflammatory precursor (22:6n-3) and a decrease in the pro-inflammatory precursor (20:4n-6) in radiolabeled rainbow trout hepatocytes. The research investigated the effects of additive coriander powder on the growth, feed utilization, survival rate, and body chemical composition of common carp Cyprinus carpio which showed an increase in protein efficiency ratio and protein productive values. An increase in dry matter and raw protein percentage, and a decrease in fat percentage were observed. The research was conducted to evaluate the effects of dietary supplementation of Coriandrum sativum seed powder (CP) and extract (CE) on some immune functions of Oreochromis niloticus, without or with exposure to the immunotoxic metal lead. The coriander dietary supplementation, especially the extract (CE) at 30 mg/kg diet, could enhance the immune response of O. niloticus and counteract the immunotoxic effects of lead exposure.
