“…Taste buds are chemosensory structures for a specific selection of food, which can be found in lips, oral cavity, gills, oesophagus and also in the body surface of several fish species (Kapoor et al ., 1976; Teles et al ., 2017), including characids (Boudriot & Reutter, 2001; Devitsina & Golovkina, 2018; Neumann et al ., 2018). The presence of taste buds in the oesophagus of dourado may contribute for food‐quality detection and segregation, whether for rejection of an item or for its acceptance and consumption, mainly in the early stages of life when dourado feeds basically plankton and protozoa (Della Flora et al ., 2010).…”

The digestive system of teleost shows remarkable functional and morphological diversity. In this study, the digestive tract and accessory organs of dourado Salminus brasiliensis are characterized using anatomical, histological, histochemical and immunohistochemical analyses. The existence of taste buds bordered by microridges in the oesophagus of dourado was recorded for the first time, thus showing that the species drives food intake by either swallowing or rejecting the food item. The Y-shaped stomach of dourado consisted of cardiac, cecal and pyloric regions with tubular gastric glands registered solely in the cardiac and cecal segments. The intestine is a short N-shaped tube with two loops, an intestinal coefficient of 0.73. The structure of pyloric caeca is similar to that of the intestine wall, comprising tunica mucosa, tela submucosa, tunica muscularis and tunica serosa layers. Histochemical analyses revealed an increased incidence of goblet cells from the midgut to the hindgut segment.A well-developed enteric plexus of scattered nerve cell and fibres are found along the digestive tract, and the calcitonin gene-related peptide (CGRP) immunoreactive neurons and fibres were identified in the myenteric plexus from the oesophagus to the hindgut. The exocrine pancreas appears diffuse in the mesentery around the stomach, intestine and also reaches the liver, and the endocrine pancreas is organized as a few islets of Langerhans. The liver comprises three distinct, asymmetric lobes, and the portal triad arrangement was registered in this tissue.

“…Fish have well-developed chemoreception due to olfactory and gustatory analyzers [9,10,11,12,13,14]. Studies aimed to identify the preference of feeds with one or another smell and taste are numerous, but, as a rule, they are not related to the determination of the fish yielding qualities (A.O.…”

Influence of free choice of feed on the productive qualities of two-year-old carp (cyprinus carpio l.) in ponds

et al. 2021

The results of research on the effect of feed with different feeding values and organoleptic properties on the productivity of two-year-old carp are presented. Within the same pond, the joint use of demand feeders (feeds with different tastes) makes it possible for fish to choose one of them in response to well-developed chemoreception. Diets of different calories affect the quality of the resulting fish production at different feed consumption. The combination of two feed types within one pond provides fish food savings per gain, despite the higher total consumption. Two-year-old fish give preference to more high-energy fish food. At the same time, fish consume 1/3–1/4 of low-energy food, regardless of the feeding time. The mass of fish consuming only low-energy fish food is 1.7 and 2.6 times less than that of fish consuming only high-energy fish food and fish simultaneously consuming these two foods, respectively. Combined feeding contributes to an increase in the relative muscle mass, primarily in comparison with fish fed only a high-energy diet. Fish-farming biological characteristics indicate higher fish yielding qualities in the case of simultaneous use of two types of feed (K-111 and Karp-38/12). Taste priorities must be considered in aquaculture fish farming.
