The aim of this study was to investigate the effects of different levels of low molecular weight sodium
alginate in carp diets on growth performance and mucosal immunity indexes in Cyprinus carpio. For this
purpose, 240 carps with an average weight of 19.12 g of 0.40 were prepared and stored in 12 tanks of 200
litres (4 treatments and each treatment in 3 replicates). At the end of the experiment, growth indices, total
mucus protein, total mucus immunoglobulin and mucus lysozyme were measured. The results showed that
there was no significant difference in growth indices, total mucus immunoglobulin and mucosal lysozyme
between treatments fed with low molecular weight sodium alginate and control group (P >0.05). However
, a significant increase in total mucus protein was observed in all treatments containing sodium alginate
compared to the control group (P <0.05), and the highest total protein content of mucus was observed in
1% sodium alginate treatment (P <0.05), In general, the results of this study indicate that a diet containing
low molecular weight sodium alginate with a significant increase in the total protein content of mucus
stimulates and increases immunity in common carp.
