Abstract


Penelitian ini bertujuan untuk untuk mengetahui gambaran histologi dari esofagus, lambung dan usus ikan garing (Tor tambroides) yang hidup di Sungai Jorong Ikan Banyak, Kabupaten Lima Puluh Kota Provinsi Sumatera Barat. Penelitian ini menggunakan organ esofagus, lambung dan usus dari tiga ekor ikan garing kemudian diproses secara histoteknik dengan pewarnaan Hematoksilin Eosin (HE) kemudian diamati menggunakan mikroskop digital. Hasil penelitian menunjukkan bahwa saluran pencernaan ikan garing terdiri dari empat lapisan yaitu tunika mukosa, submukosa, muskularis dan serosa. Mukosa esofagus ikan garing terdiri atas epitel silindris selapis dan terdapat sel-sel mukosit. Tunika submukosa tidak dijumpai adanya kelenjar esophagial. Tunika muskularis terdiri dari otot sirkuler. Mukosa proventrikulus terdiri atas epitel silindris selapis, terdapat limfonodus pada lamina propria. Tunika muskularis terdiri dari otot sirkuler. Mukosa usus terdiri atas epitel silindris selapis dan ditemukan sel goblet yang bertambah banyak jumlahnya menuju usus distal. Tunika muskularis tersusun dari otot sirkuler. Secara umum struktur histologi dinding esofagus, lambung, dan usus ikan garing hampir sama dengan ikan lainnya yang sejenis. Perbedaan hanya ditemukan pada tunika muskularis.(The aim of this study was to investigate the histological structure of the oesophagus, ventriculus and intestines of garing fish (Tor tambroides) that lives in the Jorong Ikan Banyak River, Lima Puluh Kota Regency, West Sumatera Province. Specimens for histological examination were collected from the oesophagus, ventriculus, and intestinal of three garing fish, then processed using histotechnik and stained in Hematoxilin and Eosin (HE) and then observed under light microscope. The result showed that digestive tract of garing fish is composed of four layers which are tunica mucosa, submucosa,  muscularis and  serosa. Oesophagus mucosa in garing fish was composed of  simple columnar epithelia and many mucosit sel. Oesophagial gland was not found in tunica submucosa. Tunica muscularis was composed of circular muscle. Proventriculus mucosa consisted of simple columnar epithelia, are limphonodus on the lamina propria. Tunica muscularis shaped circular muscle. Intestinal mucosa was composed of simple columnar epithelium with goblet cells that high number to distal intestine. Tunica muscularis was composed of circular muscle. Generally, histological structure of oeshophagus, ventruculus and intestinum on garing fish almost similiar to other fishes. The significant  difference is found in tunica muscularis.)
