Last Friday, we visited the Mukhia Fish Breeding Farm (मुखिया मत्स्य प्रजनन फार्म), located at Nanupatti, Dhanusha. The farm, established on 2046/01/01.
The field visit to the fish farm provided practical knowledge about carp culture, including hatchery operations and broodstock management.
The farm used a 15×5 ft hatchery tank for breeding major carps such as common carp, rohu, grass carp, and bighead. Common carp brooders weighed around 1.5 kg and were matured within 4–6 months.
Brooders were kept separately and conditioned properly before breeding. Water quality was emphasized as the most important factor, as poor water leads to slow movement, change in egg color, fungal infection, and ammonia toxicity.
Feeding practices included rice bran, mustard oil cake, fish meal, and other supplements, with fry requiring around 1–2 kg of grain per day depending on stocking.
Overall, the visit helped us understand hatchery management, feeding, species rearing, and common problems such as fungal growth and ammonia accumulation.
