Title

INVESTIGATION ON MORPHOLOGY AND POPULATION STRUCTURE OF COBITIS TAENIA IN THE TALAR RIVER, MAZANDARAN

Pages

  81-88

Abstract

 This study has been done at two stations in TALAR RIVER, Mazandaran during Oct. 2008 to Sept. 2009. The purpose of this study was assessment of MORPHOLOGY and population structure of COBITIS TAENIA in TALAR RIVER. Samples were collected and killed using electro shocker (300 V). The fish were fixed in%10 formalin. A total of 410 specimens of COBITIS TAENIA were examined and 6 meristic and 38 morphometeric factors were investigated. Results showed that in this river the fish has not hard fin rays. The fish has 6 soft rays in dorsal fin and 5 branched rays in anal fin, 39 vertebra, 18 gill rackers and also the average length of head was 10.42 mm. Head width was 5.49 mm and height of head was 6.95 mm, distances between eyes was 3.01 and height of body was 8.46 mm. The length of caudal peduncle was 5.35 and length of dorsal fin was 17.50, height of dorsal fin was 4.64. The length of pectoral fin, length of pectoral fin and height of pectoral fin were 9.77, 3.98 and 7.94 mm respectively. Generally the proportion of fishes has been reviewed. 29% of females and 38.5% of males and 32.4% of immature fishes have been studied. The 4 numerical meristic and 5 morphometric factors had significant differences between two stations (p<0.05) and%30 of the factors had significant differences. The review of population structure of COBITIS TAENIA has been shown that mean age of the fish has been 1.07 year. The equation for male W=0.671´TL+0.043 and female W=1.593´TL+0.061 has been determined for correlation between total length and total weight of the fish.
