    Ciliated epithelium in the gut of larval Atlantic halibut, Hippoglossus hippoglossus (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 42 (1993), S. 0 
    Details
    ISSN: 1095-8649

    Topics: Biology
    Notes: The presence of cilia was documented in the hindgut of larval Atlantic halibut (Hippoglossus hippoglossus) with the use of electron microscopy. Cilia were shown to be present as late as 8 and 9 day post hatch. These observations were compared to similar observations in more primitive teleosts.

    A comparative histological and histochemical study of the post-gastric alimentary canal from three species of pleuronectid, the Atlantic halibut, the yellowtail flounder and the winter flounder (1996)

    Notes: The histology and mucus histochemistry of the pleuronectid post-gastric alimentary canal was examined using light and electron microscopy. Distinct differences in goblet cell mucus histochemistry were observed between species, with the two closest taxonomic species, the winter flounder and the yellowtail flounder showing the most diversity and the halibut showing regional variation. Numbers of goblet cells within post-gastric regions did not differ significantly between species, but were significantly different between regions within species increasing toward the rectum. The post-gastric region was divisible into two areas based upon the ultrastructural features of lipid digestion and absorption in the intestine and pyloric caeca, and of exogenous protein in the rectum. The combination of species-specific histochemical differences in mucus and general histological and ultrastructural differences within the post-gastric regions between these species suggest a correlation between lumenal environmental conditions/histology and natural prey preference.

    Comparison of routine oxygen consumption rates of three species of pleuronectids at three temperatures (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of applied ichthyology 13 (1997), S. 0

    Notes: The oxygen consumption rates of three species of pleuronectids, the yellowtail flounder, Pleuronectes ferrugineus (Storer), the winter flounder, Pleuronectes americanus (Walbaum), and the American plaice, Hippoglossoides platessoides (Fabricius), were examined under simulated, land-based, aquaculture conditions. Routine oxygen consumption (ROC) rates for groups of each species were measured simultaneously using single-pass, flow-through respirometry. This study was conducted over three seasons at temperatures from 2°C to 14°C. An analysis of variance identified a significant interaction between temperature and species on the oxygen consumption rates of these flounder. The analysis indicated that at each temperature, ROC rates were significantly different among the three species (P 〈 0.05). A subsequent test of each species'ROC rate across the three temperatures indicated that both the yellowtail flounder and the winter flounder had significantly different ROC rates at each temperature experiment (P 〈 0.05). The ROC of yellowtail and winter flounder responded similarly to changes in experimental temperatures.

    Distribution and ontogeny of digestive enzymes in larval yellowtail and winter flounder (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 53 (1998), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The distribution of digestive enzymes was studied using histoenzymological methods in yellowtail and winter flounder larvae reared on three different diets: live food, weaned at day 15, or starved. Alkaline phosphatase, dipeptidyl peptidase IV, aminopeptidase M and esterase were present at 3 days post-hatch and became differentially distributed coinciding with morphological development. For larvae fed a live diet, activity of these enzymes was present in the intestine of both species and rectum of yellowtail flounder. Alkaline phosphatase was also present in the post-oesophageal swelling (stomach anlage) of winter flounder. Activity of all enzymes was absent in starved winter flounder larvae and a decrease in aminopeptidase M and esterase activity occurred in starved yellowtail flounder larvae. Acid phosphatase was not identified in either species. The eVect of weaning on enzymatic activity was not evaluated fully as the larvae did not survive long enough after the introduction of the artificial diet to complete experimentation.

    Ontogeny of the digestive tract during larval development of yellowtail flounder: a light microscopic and mucous histochemical study (1997)

    Topics: Biology
    Notes: The histological development and mucous histochemistry of the alimentary tract in larval yellowtail flounder were studied using light microscopy. Samples were taken when the larvae were first offered food at 3 days post-hatch, then at 7, 10, 29, 36, and 46 days post-hatch, at which time they were metamorphosing. Regional partitioning of the digestive tract into the buccal cavity, pharynx, oesophagus, post-oesophageal swelling (PES), intestine, and rectum was complete by day 10. Goblet cells were present only in the buccal cavity, pharynx and intestine by day 7, but increased in number and distribution as development continued. By day 29, the posterior zone of the oesophagus had a marked increase in goblet cell density and mucosal folding. At the transition from oesophagus to PES/stomach stratified epithelium with goblet cells changed abruptly to a columnar epithelium with no goblet cells. Multicellular glands in the PES of 36-day larvae allowed it to be defined as a stomach. The distinct brush border of columnar epithelium and the presence of goblet cells characterize the intestine and rectum. All goblet cells throughout the digestive tract were strongly positive for acid mucins as was the luminal layer of the stratified epithelia lining the buccal cavity, pharynx and oesophagus. The PES/stomach epithelium stained weakly for neutral mucins. No mucin staining was associated with the gastric glandular epithelium. The brush borders of the intestine and rectum were strongly positive for combinations of neutral and acid mucins.
