Prawn farming, also known as shrimp farming, is a lucrative aquaculture business that has been growing in popularity around the world. It involves breeding and raising prawns in ponds or tanks for commercial purposes. The prawn farming business has significant economic benefits, as it contributes to food security, provides job opportunities, and generates income for farmers and entrepreneurs.
Prawn cultivation is an increasingly popular practice in India, with a growing number of farmers turning to this lucrative industry. The country is one of the largest producers of prawns in the world, with a rich history and culture of seafood consumption. In this blog, we will delve into the world of prawn farming in India, exploring the benefits, challenges, and opportunities in this exciting industry.
Methods of Prawn Farming
There are several methods of prawn farming, each with its own unique advantages and disadvantages. The most common methods are:
Pond Culture
- Pond culture is the most traditional method of prawn farming. It involves the construction of large, shallow ponds in which the prawns are raised. The ponds are filled with freshwater or brackish water and the prawns are fed a diet of fish and other marine organisms. Pond culture is relatively low-cost and requires minimal technology, making it a good choice for small-scale farmers.
Raceway Culture
- Raceway culture involves the use of long, narrow tanks or channels that are designed to simulate the natural flow of water. The tanks are filled with water and the prawns are raised in a similar manner to pond culture. This method is more expensive than pond culture but allows for more efficient use of space and water.
Recirculating Aquaculture Systems (RAS)
- RAS is a closed-loop system that recirculates water through a series of filters and bio-filtration units. The prawns are raised in tanks and fed a diet of commercial feed. RAS is the most expensive method of prawn farming but also the most efficient in terms of space and water use.
Water Quality in Prawn Farming
Prawn culture is a lucrative business in India. However, one of the critical factors that determine the success of this venture is water quality. Water quality is essential for the growth and survival of prawns. In this blog, we will discuss in detail the importance of Freshwater prawn farming in India and how to maintain it.
Water quality refers to the physical, chemical, and biological characteristics of the water that affect its suitability for a particular purpose. In prawn farming, water quality is crucial because prawns are highly sensitive to changes in water quality. Poor water quality can result in stunted growth, disease outbreaks, and death of prawns, which can lead to huge losses for the farmer.
One of the critical factors that determine water quality is pH. The pH of water refers to its acidity or alkalinity. In prawn farming, the optimal pH range is between 7.0 and 8.5. Any deviation from this range can affect the growth and survival of prawns. To maintain the optimal pH range, farmers need to test the water regularly and add lime or acid as necessary.
Another essential factor that affects water quality is dissolved oxygen (DO) levels. DO is the amount of oxygen dissolved in water. Prawns require oxygen for respiration, and low DO levels can lead to suffocation and death. The optimal DO levels for prawn farming are between 4 and 6 mg/L. To maintain the optimal DO levels, farmers need to ensure adequate aeration and water circulation.
Water temperature is another critical factor that affects prawn growth and survival. Prawns are cold-blooded animals and are highly sensitive to changes in water temperature. The optimal water temperature range for prawn farming is between 26°C and 32°C. Temperatures above or below this range can lead to stress, disease outbreaks, and death of prawns. To maintain the optimal water temperature, farmers need to use temperature control systems such as heaters and coolers.
Apart from pH, DO levels, and water temperature, other factors that affect water quality in prawn farming include salinity, turbidity, ammonia levels, nitrite levels, and phosphate levels. Salinity refers to the amount of dissolved salts in water. Prawns require a specific salinity range for optimal growth and survival. The optimal salinity range for prawn farming is between 20 and 30 ppt (parts per thousand).
Turbidity refers to the clarity of water. Prawns require clear water for optimal growth and survival. High turbidity levels can reduce the amount of light that reaches the prawns, which can affect their growth and survival. Farmers can maintain low turbidity levels by using settling ponds and filtration systems.
Ammonia levels, nitrite levels, and phosphate levels are indicators of water pollution. High levels of these substances can be toxic to prawns and can lead to disease outbreaks and death. To maintain water quality, farmers need to monitor these levels regularly and take appropriate measures to reduce them.
To start prawn farming in India, farmers need to ensure that they have access to good quality water. Good quality water is water that is free from pollutants and has the optimal physical, chemical, and biological characteristics for prawn farming. Farmers can obtain good quality water from wells, boreholes, and surface water sources such as ponds, lakes, and rivers.
If the water quality is not suitable for prawn farming, farmers can improve it by using water treatment methods such as aeration, filtration, and disinfection. Aeration involves adding oxygen to the water to increase DO levels, while filtration involves removing impurities from the water. Disinfection involves using chemicals such as chlorine to kill harmful microorganisms in the water.
Prawn farming is an important industry that has grown in popularity in recent years due to the increasing demand for seafood. However, like any form of aquaculture, prawn farming is not without its challenges, including the threat of various diseases that can quickly spread and decimate a farm’s stock. In this blog, we will explore the common diseases that affect prawns, how to prevent them, and effective control measures. Our aim is to provide farmers with comprehensive information on how to ensure the health of their prawn stock and boost their profitability in the industry.
Common Prawn Diseases
- White Spot Disease
White Spot Disease is a highly contagious viral infection that causes white spots to appear on the prawns’ exoskeletons, and can rapidly spread through a farm. The disease is caused by the white spot syndrome virus, which can survive in the water and in prawn carcasses for extended periods. The disease can be fatal if not controlled early, leading to severe losses for farmers.
- Yellowhead Disease
Yellowhead Disease is another serious viral infection that affects prawns, causing yellow spots to appear on the exoskeletons, and can lead to death in a matter of days. The disease is caused by the yellowhead virus, and can quickly spread through a farm if not controlled early.
- Taura Syndrome
Taura Syndrome is caused by the Taura virus, a highly contagious disease that affects prawns, and can lead to a significant reduction in yield. Symptoms include reddening of the prawn’s shell, and high mortality rates.
Prevention Measures
- Hygiene and Biosecurity
One of the best ways to prevent the spread of prawn diseases is through proper farm hygiene and biosecurity measures. Farmers should ensure that the farm is regularly cleaned and disinfected to prevent the buildup of harmful pathogens. Additionally, farmers should control the movement of people and equipment into and out of the farm to prevent the introduction of harmful pathogens.
- Water Quality Management
Prawns require clean water to thrive, and poor water quality can lead to stress and disease. Farmers should monitor water quality parameters such as temperature, pH, and dissolved oxygen levels to ensure optimal conditions for the prawns. Additionally, farmers should regularly test water for harmful pathogens and toxins to detect any potential problems early.
- Stocking Density
Overcrowding can lead to increased stress levels and disease susceptibility among prawns. Farmers should ensure that they do not exceed the recommended stocking densities, as this can lead to poor water quality and disease outbreaks.
Control Measures
- Quarantine and Depopulation
If a disease outbreak occurs, farmers should immediately quarantine the affected prawns and depopulate the infected areas to prevent the spread of the disease. Infected prawns should be removed and destroyed to prevent the buildup of harmful pathogens.
- Chemical Treatment
Farmers can also use chemical treatments to control the spread of diseases. However, this should be done with caution, as overuse of chemicals can lead to the buildup of harmful residues and environmental damage. Chemical treatments should only be used as a last resort after other control measures have failed.
- Vaccination
Vaccination is another effective control measure that can be used to prevent the spread of diseases. Vaccines are available for some prawn diseases, such as White Spot Disease, and can significantly reduce the incidence of the disease. Farmers should consult with their veterinarian to determine the best vaccination program for their prawn stock.
Prawn diseases can significantly impact the health and profitability of a farm if not adequately controlled. Proper hygiene and biosecurity measures, water quality management, and stocking density are effective prevention measures, while quarantine and depopulation, chemical treatment.
