Resumen
Optimizing growth and feed conversion ratios by improving gut function and health is critial to ensuring costeffective production in aquaculture, especially in the current context of low fishmeal and low fish oil-based
diets. However, the use of practical diets based on high levels of plant-based raw materials as an alternative
to traditional marine ingredients has been associated with negative effects on fish performance, feed utilization,
and health. Organic acids and their salts have been widely used as functional ingredients not only for their
antimicrobial and immunomodulatory properties, but also for their potential to promote animal digestive capacity and gut health. The aim of the present study was to evaluate the effects of a mixture of formic acid and
sodium formate (Amasil NA®, BASF, Germany- AMA diet) at a dietary level of 0.3%, on key performance indicators, gut morphology and disease resistance to Vibrio anguillarum in juvenile gilthead sea bream (Sparus
aurata). The results of the present study showed that fish fed the AMA diet for 8 weeks, performed similar to fish
fed the control diet in terms of growth but presented an optimization of 8% in the utilization of a low in fishmeal
and high in plant proteins based diet. The AMA-diet also increased the folds length of gilthead sea bream anterior
gut, increasing intestinal absorption area, and decreasing the submucosa width and goblet cell size in the posterior gut when included in a high dietary plant protein content diet. Furthermore, dietary supplementation with
Amasil NA® at 0.3% increased gilthead sea bream disease resistance against V. anguillarum compared with fish
fed the unsupplemented diet. These results highlight the potential of this combination of formic acid and sodium
formate based product as a feed efficiency enhancer, and as a gut health promoter in gilthead sea bream plant
protein-based diets.
