Effects of date palm fruit extracts on skin mucosal immunity, immune related genes expression and growth performance of common carp (Cyprinus carpio) fry
چکیده انگلیسی


• First report on immunomodulatory effects of date palm fruit extracts (DPFE) on fish.
• DPFE significantly increase skin mucosal immunity in carp fry.
• Immune related genes expressions were not remarkably affected by dietary DPFE.
• DPFE improved growth performance of carp fry.

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 kg−1. 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 α [tnfa], lysozyme [ly] and interleukin-1-beta, [il1b]) in the head-kidney were studied. The results revealed that feeding carp fry with 200 ml kg−1 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.
