영문 초록

The digestive tract of the spotted sea bass, Lateolabrax sp. composed of esophagus, stomach, intestine and seventeen or eighteen pyloric caeca. The relative length of gut (RLG), that is length of digestive tract to standard length, is 0.79 (n=10). Esophagus have a undeveloped submucosa and well developed muscularis mucosae. In the stomach, muscularis consists of longitudinal and circular muscle layer, and submucosa and muscularis mucosae are well developed. In the body stomach, microvilli are observed in the epithelial layer. Mucosal epithelium of the pyloric caeca and intestine composed of columnar epithelium with developed microvilli in the apical portion. Intestine have a advanced striated border and more abundant goblet cells than the pyloric caeca. Intestine is divided into the anterior, mid and posterior part by the external and histological features. The anterior intestine have a more abundant goblet cells than the other part of the intestine. The mid intestine have a advanced submucosa and more abundant absorptive cells than the other part of the intestine. And the posterior intestine have a advanced mucosal folds and muscularis.
