Which is the fish is used for larva control of malaria-
**Core Concept**
Malaria control involves interrupting the life cycle of the Plasmodium parasite, which requires targeting the mosquito vector. Fish are being explored as a novel approach to control mosquito larvae in standing water bodies.
**Why the Correct Answer is Right**
The correct answer involves using a fish species that is known to feed on mosquito larvae. The most commonly used fish for this purpose is **Gambusia affinis**, also known as the mosquito fish. This fish is a natural predator of mosquito larvae and can effectively reduce their population in water bodies.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as there is no widely recognized fish species used for larva control of malaria associated with this name.
**Option B:** This option is incorrect as there is no established evidence of this fish species being used for mosquito larva control.
**Option C:** This option is incorrect as this fish species is primarily a predator of small invertebrates, not mosquito larvae.
**Clinical Pearl / High-Yield Fact**
It's essential to note that while fish can be an effective tool in controlling mosquito larvae, their use should be integrated with other control measures, such as insecticide treatment and biological control methods, to achieve optimal results.
**Correct Answer: C. Gambusia affinis, the mosquito fish.**
