Hint: Growing a single species of fish, or any organism is defined as a ‘mono’ culture, where ‘mono’ means a single object. Growing more than one species of a particular organism would mean a ‘poly’ or multi cultivation.

Complete step by step answer:
- Growing more than one species of fish is known as polyculture. Polyculture is a type of pisciculture, which is fish farming, or breeding and raising fish for commercial purposes. Pisciculture is mainly of three types, monoculture, monosex culture, and polyculture.
- It is also known as mixed or composite fish farming.
- This technique is mainly employed for the total utilization of all niches present in a water body like a pond. Different species of fish would consume different types of food, hence all the resources present naturally in the pond can be utilized completely.
- Polyculture is employed to raise two or more compatible species of fish together.
- Moriculture is the large- scale cultivation of mulberry plants to harvest their leaves to use them as feed for silkworms. Sericulture, the cultivation of silkworms, is dependent on moriculture.
- Aquaculture, which is also known as aquafarming, is the cultivation of fish, algae, aquatic plants, shellfish, and all other aquatic organisms. A pisciculture is a form of aquaculture.
- Monoculture is the practice of growing or raising a single species, crop, or plant on land or water body. This term is used in agriculture, where a single crop is grown at one time on land.
So, the correct answer is ‘(d) Polyculture’.

Note: Polyculture is also used to control the pond environment. If a pond has algal bloom due to the unnatural presence of manure or chemicals, fishes that feed on algae, organisms that feed on algae, phytoplankton, etc. can be raised to control their population.
