Özet:

 

In order to assess the impact of water quality, sex and seasons on the length-weight relationship, we examined the exotic fish, Carassius carassius in three water bodies of Kashmir Himalayas. The 'b' value was higher in lake having the lowest nutrient enrichment level, showing that water quality may influence the growth of a fish. The results showed positive allometric growth (b>3.0; heavy group) in Manasbal and Anchar Lakes and isometric growth of equal increment of both parameters of length and weight in the Dal Lake. The correlation between length-weight relationships showed significant (P<0.05) positive trend. Females showed 'b' value more than males in two lakes (Anchar and Manasbal lakes), whereas 'b' value was high in males (b = 2.8) in Dal Lake. Data showed significant (P 0.05) relationship in Anchar Lake. Multiple comparisons also showed significant (P<0.05) differences in 'b' values among different seasons in Dal Lake. In addition, 'b' value showed significant  (P<0.05) difference with some physico-chemical features in Dal lake. Finally, we concluded that length-weight relationship in case of Crucian carp showed significant variation in three lakes with respect to water quality, season and sex. 	 	 		 .
