The aim of this study was to investigate the effects of date palm fruit extracts (DPFE) on skin mucosal
immunity, immune related genes expression and growth performance of fry common carp (Cyprinus
carpio). One hundred and twenty specimens (4.06 ± 0.13 g) were supplied and allocated into six aquaria;
specimens in three aquaria were fed non-supplemented diet (control) while the fish in the other 3
aquaria were fed with DPFE at 200 ml kg1
. At the end of feeding trial (8 weeks) skin mucus immune
parameters (total immunoglobulins, lysozyme, protease and alkaline phosphatase activity) and immune
related gene expression (tumor necrosis factor a [tnfa], lysozyme [ly] and interleukin-1-beta, [il1b]) in the
head-kidney were studied. The results revealed that feeding carp fry with 200 ml kg1 DPFE remarkably
elevated the three skin mucus immune parameters tested (P < 0.05). However, evaluation of immune
related gene expression demonstrated that the expression of tnfa and il1b was considerably decreased
(P < 0.05) in fish fed DPFE diet, while the expression of ly remained similar (P > 0.05) compared to
control fish (fed control diet). Furthermore, growth performance parameters were significantly improved
in fry fed DPFE (P < 0.05). More studies are needed to understand different aspects of DPFE administration
in fry mucosal immunity.
