  Immunostimulants offered to fish in feed are considered to confer protection against various bacterial diseases but the effects on the antiparasitic response are largely unknown. Therefore effects of dietary β-1,3-glucan on innate immune parameters of juvenile rainbow trout Oncorhynchus mykiss and on susceptibility to the skin-parasitic cili- ate Ichthyophthirius multifiliis (Ich) have been investigated. A basal diet (dry pelleted feed) was supplemented with 0% (control), 0.2% (low), 2.0% (medium), and 5.0% (high) of the β-1,3-glucan particulate insoluble algae glucan, paramylon, from Euglena gracilis. Fish (total 440) were divided into four groups each with 110 fish (kept in duplicate tanks of 55) and each diet was fed to two replicate groups at a daily feeding rate of 1.5% of fish biomass for 56 consecutive days. Liver and plasma sampling was performed at day 0.. View More»
