Better Pond Management Can Raise Fish Production, What Should Small Farmers Do Differently?

A pond can produce much more fish when farmers manage it scientifically. Water quality, stocking density, feeding and fish health all affect growth and survival. Recent ICAR training programmes across India are encouraging small fish farmers to move from traditional practices towards better pond management.

In July 2026, ICAR-CIFRI scientists trained fish farmers in Sikkim on scientific pond management and water quality management. The programme also demonstrated advanced aquaculture technologies and discussed ways to improve fish productivity and farm profitability. Sixty-three fish farmers participated in the programme.

A similar programme in the Sundarbans trained 134 small-scale fishers in sustainable small indigenous species and carp polyculture. Farmers were trained in pond preparation, stocking density, water quality, feeding, disease prevention and other management practices.

These examples show that fish farming is not only about putting fingerlings into a pond and waiting for harvest. Regular observation and timely management can make a major difference to the performance of a pond.

Why does pond water quality matter?

Fish live in the water throughout their production cycle, so changes in water quality can quickly affect their health. Farmers need to watch for changes in fish behaviour, water condition and feeding response. Poor water quality can increase stress and make fish more vulnerable to disease.

ICAR advisories recommend maintaining suitable pond conditions and keeping records of important activities and inputs. Farmers should observe fish regularly and respond quickly when they notice unusual swimming, reduced feeding, gasping or other changes in behaviour.

Pond preparation is also important before stocking. Farmers should repair damaged embankments, remove unwanted material and prepare the pond properly. Where recommended, liming can help stabilise pond conditions. The exact treatment should depend on the pond’s soil and water characteristics rather than following a fixed dose without testing.

Water depth also matters. During periods of insufficient rainfall or inflow, ICAR advises farmers to consider desilting, rainwater harvesting and maintaining adequate depth. Lower water levels can increase temperature fluctuations and create stressful conditions for fish.

Can too many fish reduce farm returns?

Stocking more fish does not automatically mean a larger harvest. If a pond contains more fish than its natural and managed resources can support, competition for oxygen, food and space can increase. Feed costs can also rise, while poor water quality can affect fish growth.

Farmers should therefore follow stocking recommendations for the species, pond size and production system. In composite carp culture, ICAR advisories recommend structured stocking and regular monitoring rather than simply increasing fish numbers.

Feeding also needs attention. Farmers should calculate feed according to fish biomass and observe how quickly the fish consume it. Excess feed that remains in the pond can increase organic loading and affect water quality.

The Sundarbans training programme also highlighted feeding strategies as part of scientific pond management. Farmers were taught that better feeding practices can support fish growth while reducing unnecessary feed use.

Farmers should also select healthy, quality fingerlings. Weak or stressed seed can reduce survival and affect the final harvest. In Ganga Sagar, ICAR-CIFRI recently trained farmers in quality seed selection, stocking density, feed management, water-quality management and fish health monitoring.

Can farmers combine different fish species?

Polyculture can help farmers use different parts of a pond’s available food resources. Carp-based systems can combine species with different feeding habits. Small indigenous fish can also be included in suitable systems.

ICAR-CIFRI recently promoted small indigenous species and carp polyculture in homestead ponds in the Sundarbans. The model was designed not only for income but also for household nutrition because many small indigenous fish contain important protein and micronutrients.

Farmers should not copy a stocking combination without checking whether it suits their pond. Species compatibility, seed availability, water conditions, market demand and local climate all need to be considered.

Integrated fish farming can provide another option. ICAR’s eastern regional centre has trained farmers in systems that combine fish with horticulture and livestock. Pond dykes can support fruit trees and vegetables, while livestock activities can be linked with the wider farm system.

The approach can provide more than one source of farm income. But each component still needs proper management. A farmer should start with a system that matches available land, labour, water and market access.

What should small fish farmers do first?

Farmers planning pond fish culture should begin with good pond preparation and quality seed. They should maintain a simple pond diary recording stocking, feeding, water observations, treatments and harvesting. Such records can help identify problems and calculate the real cost of production.

Farmers should also avoid making sudden changes based only on advice from other farms. A pond’s soil, water source, fish species and climate can differ considerably from another farm. Local fisheries officers, Krishi Vigyan Kendras and ICAR fisheries institutes can provide more suitable guidance.

Scientific pond management does not necessarily mean expensive technology. Basic practices such as correct stocking, careful feeding, regular observation and proper water management can already improve farm performance.

For small farmers, the goal should be to produce more fish from the existing pond without creating unnecessary costs or environmental problems. Better management can help farmers protect fish health, reduce avoidable losses and make their pond a more reliable source of income.
