Larvicidal efficacy of four indigenous ornamental fish species of lake kolleru, India
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 1
Abstract
A study was conducted to assess the larvivorous potential of the indigenous ornamental fish fauna of Lake Kolleru (Andhra Pradesh, India), a wetland of international importance. Indigenous larvivorous fishes have potential for regulating mosquito larvae. The mosquito larval preference of four indigenous larvivorous fishes (Amblypharyngodon mola, Colisa lalia, Mystus bleekeri and Rasbora daniconius) was assessed to highlight their importance in mosquito control management. The fishes consumed a considerable amount of mosquito larvae in laboratory conditions. The consumption rate of mosquito larvae by four different indigenous fish species of ornamental value under laboratory condition revealed that, among the four species, mean consumption of the Rasbora daniconius is highly significant (P<0.01) followed by Colisa lalia and Amblypharyngodon mola (P<0.05). Overall mean consumption of Mystus bleekeri for three hours is not significant but it showed a significant consumption at 2nd and 3rd hour. These fishes can be used as biological control agents in the wetlands and allied mosquito larval habitats.
