MORPHOLOGICAL STUDY OF LABEO ROHITA WITH REFERENCE TO CONDITION FACTOR (K) FROM THE RIVER MUDNA, SHAHDOL.

Vandana Ram

Abstract


The condition factor of female Labeo rohita fishes in River mudna was calculated. Condition factor is used for comparing the condition, fatness, or well-being (Mir et al., 2012) of fish, based on the assumption that heavier fish of a given length are in better condition. In present study the value of “k” was the minimum (1.7614) in December, while the highest value (3.0921) for this parameter was recorded in August when body weight and GSI also was maximum. The body width was similar  to the trend seen with “k”.The role of condition factor may be considered as regulatory in reproductive events as it confirms the availability of sufficient food to fish. A number of studies have been carried out in this field confirming role of condition factors in the regulation of fish reproduction. Similar to these findings the present experimental fish Labeo rohita also spawn when its condition factor reaches to maximum.
