Which fishes are Larvivorous?
Fish fauna surveys have been undertaken at different NIMR field units which revealed that there are several indigenous fish like Danio rerio, Esomus danricus, Badis badis, Chanda nama, Puntius ticto, Rasbora daniconius, Colisa fasciata, etc. which are commonly found in Indian fresh waters.
What kind of fish eat mosquitoes?
Goldfish, guppies, bass, bluegill and catfish prey on mosquito larvae. But the most important fish predator, by far, is the Gambusia affinis, commonly known as the mosquito fish.
Which of the following is a larvicidal fish?
Commonly called as “carpminnows” There are several species of this fish, of which Puntius amphibus, Puntius ticto and Puntius sophore are considered as efficient larvicidal fish.
Which fish is used for control of malaria?
The fish Gambusia affinis (mosquito eater) is one such bio-control agent, which feeds on mosquito larva. Thus it helps in checking the population of mosquitos. A fully grown fish can eat 100-300 mosquito larva per day.
What is Zooprophylaxis?
Background: Zooprophylaxis is the use of wild or domestic animals, which are not the reservoir host of a given disease, to divert the blood-seeking malaria vectors from human hosts.
What is the role of Larvivorous fish in stopping mosquito breeding?
A wide range of organisms helps to regulate mosquito populations naturally through predation, parasitism and competition. As biological mosquito control agents, larvivorous fish (i.e., those that feed on immature stages of mosquitoes) are being used extensively all over the world since the early 1900s (pre DDT era)7.
How long do mosquito fish live?
The lifespan of a mosquitofish averages less than a year and the maximum is about 1.5 years. However, mosquitofish kept as pets can live much longer, with owners reporting lifespans of over three years. Male mosquitofish lifespans are considerably shorter than females.

What is use of Larvivorous fish?
Some fish species eat mosquito larvae and pupae. In disease control policy documents, the World Health Organization (WHO) includes biological control of malaria vectors by stocking ponds, rivers, and water collections near where people live with larvivorous fish to reduce Plasmodium parasite transmission.
How does Gambusia fish help in controlling the spread of malaria?
“The fish, which largely feeds on mosquito larvae, will help check mosquito breeding, which causes dengue and malaria,” said Dr Madan. He said the department was taking every possible step to check the spread of the disease. The officials said dengue and malaria could be easily prevented by taking ample precautions.
