The steady growth of aquaculture production worldwide paired with reduced availability and escalating costs of feed ingredients from wild fisheries has foster the use of alternative ingredients in fish farming. Nevertheless, even if the nutritional profile covers basic requirements, there are often issues with acceptability of such feeds. This study…

This study evaluated effect of supplementation of attractants i.e. Luctarom Fish L and Luctarom Umami to diets containing lower fishmeal (FM) on feeding behavior and growth performance of white shrimp (Litopenaeus vannamei). Shrimps weighted 4g were stocked in 25 glass aquaria (240L, 50 shrimps/m3), fed following diets for 15d (n=5):…
This study aimed to test the use of chlorogenic acid (CGA), a natural antioxidant, which might act improving the retention of eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids. Fish were fed one of three experimental diets. A diet with 160 g kg−1 fish oil (FO) and 80 g kg−1vegetable oil…
Traditionally, bile acids (BA) have been viewed as detergent molecules involved in the intestinal digestion and absorption of lipids and hepatic maintenance of cholesterol homeostasis. During the last 15 years, however, it has become clear that BA are important regulatory molecules with systemic endocrine functions that signal changes in luminal…
En cualquier especie animal, la modulación del comportamiento ingestivo implica cambios en su patrón de consumo en el corto plazo, el cual se evalúa teniendo en cuenta la distribución, el número, el tamaño y la duración de las comidas a lo largo del día, partiendo de la base de que…
Gamma tocopherol (gT) exhibits beneficial cardiovascular effects partly due to its anti-inflammatory activity. Important sources of gT are vegetable oils. However, little is known to what extent gT can be transferred into marine animal species such as Atlantic salmon by feeding. Therefore, in this study we have investigated the transfer…
The evolution of the chemical senses has resulted in a sensory apparatus for high taste and smell acuity in mammals and birds to ensure self-nourishment. Such peripheral chemosensory systems function as a code to unfold the nutritional value of feedstuffs. Food ingestion simultaneously evokes odor, taste and thermo-mechanical (somatosensing) sensations.…
