“…Jaroszewska et al () suggested that, for agastric fish, the appearance of the numerous mucous cells in the esophageal epithelium was considered as morphological adaptation substituting for a functional stomach. The function of pregastric digestion in esophagus had been reported by a number of researchers (Baglole et al ; Ortiz‐Delgado et al ; Gisbert et al ; Herrera et al ). Apart from the function of pregastric digestion, the secretion of mucous cells facilitated the passage of food through the esophagus (Mai et al ), and also played a role in protecting the digestive mucosa from viral and bacterial attacks (Gisbert et al ).…”

“…Among these organs and systems, the ontogenetic development of the digestive system deserved special attention because knowledge of differentiation of the digestive tract during ontogenetic development was essential for understanding the digestive physiology of larval fish, and synchronizing the physiological stage of development with feeding practices and rearing protocols (Baglole et al 1997; Mai et al ). Up to date, researches have been conducted to determine the ontogenetic development of the digestive tract for a number of economically important fish species (Cahu and Zambonino‐Infante ; Mai et al ; Herrera et al ; Yang et al ). The majority of these studies had been involved in gastric fish, and the development of the gastric glands and the pyloric caeca was considered the last major event for larval period (Baglole et al ).…”

This study was conducted to determine the ontogenetic development of the digestive tract and its accessory structures (liver, pancreas, and gall bladder) in agastric larval Chinese sucker Myxocyprinus asiaticus with the histological and ultrastructural approaches from hatching to 56 days after hatching (DAH). On the basis of its feeding mode, and analyzing the main histological features of the digestive system, larval development in Chinese sucker was divided into three stages from hatching: stage 1 (endotrophic period): 1-6 DAH; stage 2 (endoexotrophic period): 7-14 DAH; stage 3 (exclusively exotrophic period): from 15 DAH onward. At hatching, the digestive tract of the larvae consisted of an undifferentiated straight tube. At 4 DAH, the mouth opened, and the digestive tract was differentiated into buccopharyngeal cavity, esophagus and intestine. At 7 DAH, fish started to feed exogenously. Yolk sac was completely exhausted at 15 DAH. Until 56 DAH, the digestive tract of the larvae displayed regularly arranged microvilli, abundant vacuoles, and protein inclusion bodies. The pancreas, liver, and gall bladder were functional from 6 DAH, which enabled larvae to ingest, digest, and assimilate the first exogenous food. In comparison with teleosts that have a stomach, the development of the digestive tract of the agastric Chinese sucker seemed relatively slow.

“…A similar pattern has been observed in other cephalopod species, such as Sepia officinalis and Sepioteuthis lessoniana (Semmens 2002), where cephalopods reached their total development several days after hatching (Boucaud-Camou & Boucher-Rodoni 1983). This is not exclusive to cephalopods; Herrera et al (2010) proposed and defined 3 stages for the digestive development of sole Dicologoglossa cuneata larvae, according to the feeding category and the timing of ingestion, as well as digested food as: Stage 1 or endotrophic (0 to 1 DPH, larvae only fed on vitellus), Stage 2 or mixed feeding (2 to 3 DPH, exogenous and endogenous feeding) and Stage 3 or exotrophic (4 to 33 DPH, exclusively exogenous feeding with total yolk exhaustion).…”

The cephalopod digestive gland (DG) is responsible for enzyme production as well as nutrient and lipid storage. Octopus maya (Mollusca: Cephalopoda) is a holobenthic octopus species with aquaculture potential. To develop a balanced food for the rearing of this octopus, it is necessary to understand its digestive physiology. We performed histological studies on the structural change of the DG (cytological ontogeny) associated with age (from 0 to 30 d posthatching, DPH) and food (postprandial change in 120 DPH juveniles). Early ontogeny of DG was defined in 3 stages: (1) yolk platelets stage (0 to 5 DPH), (2) transition stage (6 to 10 DPH) and (3) heterolysosomes (food reserves) stage (>12 DPH). In Stage 1, the DG had anatomically undifferentiated tubules, but was filled with yolk platelets. The tubular structures developed lumen by 5 DPH. Stage 2 (starting at 6 DPH) corresponds to mixed exogenous and endogenous feeding. At that time, the yolk platelets were gradually consumed until completely exhausted at 9 DPH. At the onset of Stage 3, the DG structure was completely tubular, exhibiting digestive cell microvilli and other cellular features typical to octupus DGs. During exogenous feeding (12 DPH and onward), acidophilic secretory lysosomes, heterolysosomes and some heterophagosomes appeared on DG cells. O. maya has long digestive cycles in which the extracellular and intracellular digestion can take up to 8 h. Although the ecological implications of this information for aquaculture will still have to be proven, results demonstrated that O. maya is an energetically efficient species and thus suitable for rearing in captivity.

“…In some species, like Dicologoglossa cuneata , these organs develop, while the larva feeds on the endogenous reserves, being rapidly functional after hatching (Hoehne‐Reitan and Kjørsvik ; Herrera et al . ). The presence of zymogen granules in the exocrine pancreas, observed in the studied E. anchoita stages, would support this fact.…”

Histological and histochemical study of the digestive system of the Argentine anchovy larvae (Engraulis anchoita) at different developmental stages of their ontogenetic development

In this work, histological and histochemical features of the larval digestive system of Argentine anchovy Engraulis anchoita were described. Structural changes during ontogenetic development were also characterized, and comparisons between the beginning and the end of larval development were made. Histological sections of larvae were subjected to histochemical and routine histological techniques to localize and differentiate glycoproteins (GPs). Both at an early and a late larval stage, the oesophageal goblet cells reacted more intensely than those of the rest of the digestive tract, and only the oesophagus exhibited metachromasia with toluidine blue techniques at different pHs, thus revealing diverse GPs at different concentrations. The GPs histochemical composition in the intestine varied with the developmental stage and the intestinal zone. The absence of goblet cells characterized the foregut; however, they started differentiation at an advanced stage in the midgut. These cells could be detected in the hindgut both at the beginning and at the end of development. The attached glands showed a varied glycoprotein composition. The digestive tract of E. anchoita presented a high level of complexity, related to the multiple functions of mucus in the digestive tract, such as lubrication, protection, antimicrobial function and ionic and osmotic regulation.
