Study was carried out in Haryana state to assess the adoption of inland fishery farming practices and constraints faced by fishery farmers of Haryana state. The findings revealed that majority of fish farmers (58.67%) possessed large size ponds and all were perennial in nature but 52.00 percent of them were using leased village ponds. The overall adoption for fish farming technology was low (56.00%). While the practices such as recommended species, watering of ponds and stocking fish seed, recommended fish seed rate or fingerlings application, proper harvesting period and pond site management practices were fully adopted by farmers whereas, least adopted practices included control of aquatic weeds, ploughing of pond, disease control measure and application of recommended manures and fertilizers. However, very serious constraints in fish farming were viz. lack of knowledge of field functionaries for post-harvest management practices, lack of knowledge of modern storage structures, non-availability of fish feed and seed at proper time in villages, lack of remunerative fish MSP policy, wide price fluctuations, high price of fish seed and no cold storages at villages. Both technological empowerment as well as remunerative and assured markets is very crucial for sustainability and profitability of this farming enterprise.
