The Growth Features Of Tench ( Tinca Tinca L., 1758 ) In The Kesikköprüdam Lake, Ahmet Altindağ, Sibel Yi̇ği̇t, Seyhan Ahiska, Şakir Özkurt

Turkish Journal of Zoology

In this study, the growth properties of tench ( Tinca tincaL., 1758) in the Kesikköprü Dam Lake between April 1995 and March 1996 were studied. In the specimens examined, ages ranged from I-VI in both sexes. The population was 51.43% female and 48.57% male. The fork length and weight in ranged from 16.1 to 41.4 cm and from 85 to 1350 g, respectively, and in males from 15.8 to 40.3 cm and from 83 to 1127 g, respectively. Age-length and age-weight relations were calculated according to the von Bertalanffy growth equation. The following values were obtained for females and males, …

The Distribution, Ecology And Growth Of The Chestnut Lamprey, Ichthyomyzon Castaneus, In The Clearwater River, Minnesota, Charles S. Holt, Paul A. Durkee

Journal of the Minnesota Academy of Science

This study dealt primarily with the ammocoete stage of the chestnut lamprey, lchthyamyzan castaneus (Girard). The population estimate for ammocoetes in the 25.5 m2 section studied was 540 individuals. The lengths of 452 ammocoetes collected ranged from 42 to 164 mm. A total of 213 chestnut lampreys were retained for laboratory study. Twenty of these were adults with an average length of 136.8 mm (range= 125 mm to 191 mm). Six age classes of ammocoetes were determined. An average increase in body length of recaptured ammocoetes of 2.9 mm was observed during the summers of 1980 and 1981. The habitat …
