Fish effective in controlling growth of Anopheles is

Options

A. Mosquito Fish Gambusia
B. Guppy fish Poecilia
C. Stickleback, Minnow and Trout
D. All the above.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a type of fish that is effective in controlling the growth of Anopheles mosquitoes, which are known vectors for malaria.

2. **Identifying the Problem**: Anopheles mosquitoes, particularly the female, are responsible for transmitting malaria by introducing the Plasmodium parasite into humans through their bites. Controlling their population is crucial for preventing malaria.

3. **Researching Larvivorous Fish**: Larvivorous fish are species that feed on mosquito larvae. Introducing these fish into stagnant water bodies can help reduce the mosquito population by consuming their larvae before they mature into adult mosquitoes.

4. **Identifying Specific Fish**: One of the most well-known larvivorous fish is Gambusia, commonly referred to as the mosquito fish. Other examples include Panchax, Haplocypris, and Trichogaster.

5. **Conclusion**: The fish that is effective in controlling the growth of Anopheles mosquitoes is Gambusia. This fish, along with other larvivorous species, can significantly reduce mosquito larvae in stagnant water, thereby preventing the breeding of mosquitoes and the spread of malaria.

**Final Answer**: Gambusia is the fish effective in controlling the growth of Anopheles.
