Abstract

Abstract Histology offers a powerful tool in the study of detailed structures of different tissues in fishes. It is used for sex verification, identifying stages of development, presence of parasites, tumors diagnosis, other abnormalities and changes in the arrangement of tissue layers including the digestive tract. In this study, not having found any existing report, the digestive tract histology of the Persian tooth-carp, Aphanius persicus (Jenkins, 1910), was investigated. The dentition comprised canine-like teeth in one row with sharp tips. Esophagus consisted of small portion between pharynx and stomach. Stomach showed an enlargement and the intestine is relatively short. The mucosa of total digestive tube consisted of simple columnar cells and numerous goblet cells. The liver is composed of parenchymal cells and lattice fibers whose function is to support the former. Our data showed this fish is heterodont, omnivores with no secretory stomach.

波斯齿鱼(Aphanius persicus)消化道和肝脏的组织学形态学研究(放线翼目:棘齿鱼科)
组织学为研究鱼类不同组织的详细结构提供了有力的工具。它用于性别验证、发育阶段识别、寄生虫的存在、肿瘤诊断、包括消化道在内的组织层排列的其他异常和变化。本研究在未发现任何现有报道的情况下,对波斯齿鱼Aphanius persicus (Jenkins, 1910)消化道组织学进行了研究。牙列由犬齿状的牙齿排成一排,尖齿锋利。食道由咽和胃之间的一小部分组成。胃肿大,肠较短。全消化道粘膜由单一柱状细胞和大量杯状细胞组成。肝脏由实质细胞和晶格纤维组成,其功能是支持前者。我们的数据表明,这种鱼是异体杂食动物,没有分泌胃。
