Question

Prepp Team · Accepted Answer

The question asks us to identify which of the given fish species are freshwater fishes commonly found in India. Let's examine each fish listed:

Understanding Different Types of Fish Habitats

Fish live in various environments based on the salinity of the water. These environments include:

Freshwater: Water with low salinity, like rivers, lakes, and ponds.
Marine water: Water with high salinity, like oceans and seas.
Brackish water: A mix of freshwater and marine water, like estuaries and deltas. Some fish can move between these environments.

Analysis of Given Fish Species

Let's look at each fish mentioned:

(A) Hilsa: Hilsa is an anadromous fish, meaning it spends most of its life in marine water but migrates to freshwater rivers to spawn. While it enters freshwater, it is primarily known as a brackish/marine water fish, especially in coastal areas.
(B) Pomfrets: Pomfrets are popular food fish, but they are exclusively marine fish, found in coastal waters of the Indian Ocean.
(C) Catla: Catla (Catla catla) is one of the most important and fast-growing freshwater fish species in India. It is a major carp used in aquaculture in freshwater ponds and lakes across the country.
(D) Rohu: Rohu (Labeo rohita) is another principal species of Indian major carp. It is a purely freshwater fish, native to the rivers and lakes of South Asia, including India.
(E) Common carp: Common carp (Cyprinus carpio) is a widely distributed freshwater fish that is also extensively cultured in freshwater ponds and lakes in India.

Based on this analysis, Catla, Rohu, and Common carp are definitely freshwater fish commonly found and cultured in India.

Summary Table of Fish Types

Fish Name	Primary Habitat Type	Common in Indian Freshwater?
Hilsa	Brackish/Marine (migrates to Freshwater)	No (Primarily marine/brackish)
Pomfrets	Marine	No
Catla	Freshwater	Yes
Rohu	Freshwater	Yes
Common carp	Freshwater	Yes

Conclusion on Indian Freshwater Fish

From the options provided, the freshwater fishes commonly found in India are Catla (C), Rohu (D), and Common carp (E). Therefore, the combination that includes only these three is the correct choice.

Looking at the options, the option listing (C), (D), and (E) only correctly identifies the freshwater fish among the given choices.

Revision Table: Important Indian Fish Species

Fish Name	Category	Habitat	Significance in India
Catla	Major Indian Carp	Freshwater (rivers, lakes, ponds)	Important aquaculture species
Rohu	Major Indian Carp	Freshwater (rivers, lakes, ponds)	Important aquaculture species
Mrigal	Major Indian Carp	Freshwater (rivers, lakes, ponds)	Important aquaculture species
Common Carp	Exotic Carp	Freshwater (ponds, lakes)	Widely cultured, fast growth
Tilapia	Exotic Species	Freshwater/Brackish	Increasingly cultured, controversial invasiveness
Pangasius	Exotic Catfish	Freshwater (rivers, ponds)	Popular aquaculture fish
Hilsa	Shad	Brackish/Marine (migrates to Freshwater)	Highly valued, important fishery
Pomfrets (Black, Silver)	Marine Fish	Marine	Commercially important marine fishery

Additional Information on Aquaculture in India

India is a significant player in global fish production, particularly in inland (freshwater) aquaculture. Freshwater fish farming contributes substantially to the country's food security and economy. The major Indian carps like Catla, Rohu, and Mrigal form the backbone of freshwater aquaculture practices, especially pond farming.

Other commercially important freshwater fish in India include species like Grass Carp, Silver Carp (both exotic carps), various types of Catfish (like Magur, Singhara), and freshwater prawns.

Understanding the natural habitat of fish species is crucial in fisheries management and aquaculture practices. Rearing marine or brackish water species requires different conditions (e.g., saline water tanks) compared to freshwater species.
