Seasonal changes of gonadal activity of invasive vermiculated sailfin catfish (Pterygoplichthys disjunctivus) from Polgolla reservoir in Sri Lanka

Seasonal changes of gonadal activity of invasive vermiculated sailfin catfish (Pterygoplichthys disjunctivus) from Polgolla reservoir in Sri Lanka

The present study elucidates the pattern of the reproductive activity of the invasive Pterygoplichthys disjunctivus male (n = 113) and female (n = 124) fish in Polgolla Reservoir, Sri Lanka. The reproductive activity was studied based on the gonadosomatic index (GSI), macroscopic and microscopic fea...
