Pond bottom management is essential because most of the shrimp activities happen at the pond bottom. Maintaining the pond bottom will indirectly protect water quality and shrimp health. How Pond Bottom Gets Polluted? Overfeeding causes, unutilized feeds to get converted into organic sludge. Dead Plankton, Fecal waste, and Carbonaceous matter are also converted into organic sludge. Accumulation of organic sludge leads to the formation of Ammonia, Nitrite, H2S, Vibrio Load, and Gill Chokes. How to Identify the Polluted Pond Bottom? Water color changes and gets turbid Reduced the feeding ..read more

What's the need for Pond Designing? A proper layout or design of a pond helps to reduce construction costs and also for efficient management of pond activities. Proper pond design and construction are essential for trouble-free operations and proper management of production activities. It also helps to avoid critical conditions like heavy rains, floods, and storms during culture. What are all parameters to preplan before starting pond construction? Pond shape and size Water supply canals Water inlet and outlet Drainage systems Pond bund and dykes sizes Reservoirs setup Waste d ..read more

Aquaculture in India's coastal areas is important to the economy, contributing 1.1 percent to the annual GDP. Annual aquaculture production in India has risen from 0.75 million tonnes in 1950–1951 to 14 million tonnes in 2021, second only to China. The Indian subcontinent is home to about 10% of the world's fish diversity, and more than 15 million people rely on fishing for their livelihood. Aquaculture is one of the most popular activities in India's coastal regions. Furthermore, It is a high-risk occupation in the context of cyclones because they are subject to environmental changes that end ..read more

Site selection is very important in aquaculture as this can often decide the success or failure of the culture. The following list of things need to be checked while selecting the site for shrimp pond: Water should be available from water sources throughout the culture period. A good quality water source should be preferred. The water source could be creeks, canals, lagoons or backwaters, and groundwater. The water source should be free from industrial and agricultural pollution. We have to prefer the gravity flow of the water site that facilitates easy pond bottom drying and prope ..read more

Algae is the foundation of the aquatic food chain. They can be single or multiple celled aquatic plants, that primarily produce energy through photosynthesis. The other term to describe algae is phytoplankton’s, mostly they are microscopic and controlled by water motion. Algal bloom Pond water primarily consists of different types of algal species. The single celled algal cells collectively called “algal bloom”. Generally algae pose various benefits to aquatic animals, there are some harmful species like blue green algae which has serious threats to fish/shrimp growth. Usually nutrient rich wa ..read more

Pond cleaning and drying: Before going to start a new culture ponds should be cleaned completely to remove the debris, carcasses, algal mats and dark bottom soil etc. Ponds should be dried completely under the sun till the top soil cracks. Importance of pond drying: Pond drying is the first step in pond preparation. It is more effective in eliminating unwanted species in the pond bottom. It helps to mineralize the organic content of the bottom and oxidizes the harmful substance like sulphides . Why is pond cleaning important? Waste material which is settled in the pond may contain unwanted or ..read more
