Abstract

Ompok hypophthalmus is a freshwater fish which lives flood plain river. Siak river is one of flood plain river in Riau province. Siak river is very valuable for Pekanbaru people for household to industrial purposes. The household and industrial activity may cause the decrease of water quality. The contaminated water affects the living things in this area, such as O.hypophthalmus fish. Therefore, it is necesarry to detect the water quality decrease by observing the intestine structure of O.hypophthalmus. This study aimed to find out the histological structure of intestine tissue of Ompok hypophthalmus, especially which lives in the Siak I and Siak II bridge. This study was conducted from January to April 2014. Histological slide of O.hypophthalmus intestine were made using paraffin method and stained with Hematoxylin-Eosin (HE). The results showed that the intestine parasite infections was found in O.hypophthalmus, as well as lymphocyte stacking, villous unification, epithelium lysis, and lamina propria widening. The tissue damage in intestine might be due to the content of heavy metal above the normal standard.

Abstract

This research was aimed to asses morfometric parameters of digestive tracts especially intestine and stomach of Parang-parang fish (Chirocentrus dorab Forskall 1775). This study was conducted from June to August 2012. The samples were collected using survey method. Fish samples were 76 individuals collected from fisherman in Bengkalis, Riau Province. Parameters which measured were the total body length, length of intestine, fish weight, and stomach weight. Data were analyzed using linear regression which consist of the ratio between stomach weight and fish weight with totalbody length, length of intestine with total body length, ratio between intestine length and total body length with total body length and ratio between weight of intestine and fish weight with total body length. The result indicated that parang-parang fish was considered as carnivorous fish based on the length of its intestine, i.e 0,32-0,43 times of its total body length for male fish and 0,33-0,39 times of its total body length for femalefish. Total body length of parang-parang fish was positively correlated to its intestine length and ratio between intestine length and total body length.

Abstract

Kryptopterus apogon is one of freshwater fish species that was only found in floodplain river in Riau Province. Many species of lais fish are found in Riau Province rivers and morphologically has the same shape therefore it is necessary to find alternative markers to distinguish the species. The important step in genetic analysis is DNA isolation. This study aimed to isolate the total DNA from Kryptopterus apogon. The fish samples were taken from the Kampar Kiri and Tapung Hilir rivers. Isolation of total DNA was done by taking the muscle tissue from the fish tail (1 mm x 1 mm in size). Isolation of total DNA was done using DNA isolation kit (QIAGEN DNeasy Blood & Tissue). After that, the total DNA was checked on 1% agarose gel to estimate the quantity and quality of total DNA. Total isolated DNA of Kryptopterus apogon from two rivers had various quality and quantity. Tha total quantity of DNA molecules ranged from to 100-200 ng/μl, while the total quality was good enough or not fragmented. The DNA was clear, thick, and no smear.
