Q151. Arrange the following steps of commercial broiler farming in the correct chronological order: A. Pre-heating the brooding area (Brooding) B. Cleaning, disinfection, and laying of fresh litter C. Harvesting the birds for the market (at ~35- 40 days) D. Arrival of Day-Old Chicks (DOCs) Which of the following represents the correct sequence?
Explanation
Commercial broiler farming starts with thorough cleaning and disinfection of the poultry house, followed by laying fresh litter. Next, the brooding area is pre-heated to provide the right temperature for young birds. The third step is the arrival and placement of Day-Old Chicks. Finally, after approximately thirty-five to forty days of growth, the birds are harvested for the market statewide.

Q152. The term ‘Layer’ in poultry farming specifically refers to:
Explanation
In the poultry industry, the term ‘Layer’ specifically refers to female birds that are reared for the primary purpose of commercial egg production. These birds start laying eggs at around eighteen to twenty weeks of age and continue for about a year. Management practices for layers, such as nutrition and light control, are different from those for meat-type birds like broiler chickens.

Q153. What constitutes the largest recurring cost in running a commercial poultry farm in Rajasthan?
Explanation
In commercial poultry farming, the largest recurring cost is poultry feed, which can account for up to seventy percent of the total operational expenses. The price of feed is heavily influenced by the market rates of ingredients like maize and soybean meal. Efficient feed management and high feed conversion ratios are essential for the profitability of a poultry farm in Rajasthan’s economy.

Q154. Match the items in List I with those in List II and select the correct answer using the codes given below:
Important Water Body
District/Significance for Fisheries
A. Jaisamand Lake
i. Tonk (Major reservoir for commercial inland fisheries)
B. Ramgarh Dam
ii. Udaipur (Second largest artificial lake, significant tribal fishery)
C. Bisalpur Dam
iii. Jaipur (Historic fishing, currently largely dry/seasonal)
D. Mahi Bajaj Sagar Dam
iv. Banswara (Large reservoir supporting substantial fish production)
Explanation
Rajasthan’s diverse water bodies are critical for the inland fisheries sector. Jaisamand Lake in Udaipur is a major site for tribal fisheries. Ramgarh Dam in Jaipur is a historic site, though currently seasonal. Bisalpur Dam in Tonk and Mahi Bajaj Sagar in Banswara are among the state’s largest reservoirs, providing significant potential for commercial fish production through local fishing communities.

Q155. Fisheries in Rajasthan are entirely restricted to:
Explanation
Since Rajasthan is a landlocked state with no coastline, its fisheries sector is entirely restricted to inland freshwater resources. This includes various rivers, canals, seasonal lakes, and large man-made reservoirs. The state has significant potential for fish production through the scientific management of these freshwater bodies. Inland fisheries play a vital role in providing nutritional security and livelihood opportunities to rural populations.

Q156. Which group of fishes constitutes the majority of the commercial catch from Rajasthan’s water bodies?
Explanation

Q157. The ‘National Scheme of Welfare of Fishermen’ in Rajasthan primarily provides support for:
Explanation
The National Scheme of Welfare of Fishermen aims to improve the living conditions of the fishing community in Rajasthan. Key components include providing financial assistance for building low-cost houses and accidental insurance cover. Additionally, a relief fund is established to support fishermen during the closed monsoon season when fishing is prohibited. These welfare measures are essential for social and economic security.

Q158. Consider the following statements about fisheries in Rajasthan: I. The southern and southeastern districts (Udaipur, Banswara, Dungarpur, Bhilwara) have the highest potential for reservoir fisheries. II. Fish seed production is a major constraint; hence, hatcheries have been established. III. Mahseer, a famous sport fish, is found in the freshwaters of southern Rajasthan. IV. Ornamental fish farming is slowly gaining popularity as an entrepreneurial activity. V. Fishing operations in large reservoirs are completely unregulated and open to anyone without permits. Which of the above statement(s) is/are correct?
Explanation
Rajasthan’s fisheries have high potential in southern reservoirs, though seed production remains a challenge addressed through hatcheries. The state is home to the famous Mahseer fish, and ornamental farming is gaining popularity. However, fishing in large reservoirs is strictly regulated through a licensing and leasing system, making the fifth statement incorrect. Thus, the first four statements are correct.

Q159. Which fast-growing, exotic fish species was introduced for aquaculture but has caused ecological concerns by competing with indigenous carps in Rajasthan’s water bodies?
Explanation
The introduction of certain exotic fish species like Tilapia and African Catfish has raised ecological concerns in Rajasthan’s water bodies. These species are highly aggressive and prolific breeders, often out-competing indigenous carps for food and habitat. Their presence can lead to a decline in native fish biodiversity and disrupt the traditional fishing economy. Efforts are made to promote native species aquaculture.

Q160. The practice of rearing two or more compatible species of fish together in the same pond to fully utilize all ecological niches is called:
Explanation
Composite fish culture is a modern aquaculture practice where several different species of fish are reared together in a single pond. The species are chosen based on their non-competitive feeding habits; for example, Catla feeds at the surface, Rohu in the middle, and Mrigal at the bottom. This approach ensures that all ecological niches and available nutrients are fully utilized.

Key facts from Agriculture, Horticulture, Forestry and Animal Husbandry in Rajasthan
Contour bunding and mulching are effective moisture conservation methods in arid agriculture.
Jaisalmer, Barmer and Bikaner fall in the Hyper Arid Partial Irrigated Zone.
Dry farming is the practice of growing crops in regions with less than 750 mm of annual rainfall without irrigation.
Bajra (pearl millet) is a common drought-resistant crop of the arid region; moth bean is drought-tolerant and forms a dense soil cover.
Raj 3077 is a drought-resistant wheat variety suited to low-water areas.
Early maturing varieties help crops escape terminal drought; overgrazing by livestock accelerates desertification.
Frequently asked questions
How many RAS Prelims practice MCQs are there on Agriculture, Horticulture, Forestry and Animal Husbandry in Rajasthan?
This page has 164 practice MCQs on Agriculture, Horticulture, Forestry and Animal Husbandry in Rajasthan (Health, Environment and Agriculture). Each has the correct answer, and most have an explanation.
What is dry farming?
The practice of growing crops in regions with less than 750 mm of annual rainfall without irrigation, by conserving soil moisture through methods such as mulching, bunding and early sowing.
Why is moth bean grown widely in Rajasthan?
Because it is drought-tolerant and forms a dense soil cover that protects the soil from erosion. It also fixes nitrogen, so it suits the poor sandy soils of the arid west.
Why are early maturing varieties important?
They complete their growth before the dry spell at the end of the season, so the crop escapes terminal drought. This is a key strategy for rain-fed farming in Rajasthan.
