This method, rare in Vietnam's Central Highlands, sets them apart as their district's only successful “crunchy carp” producers. The technique involves feeding the fish a special diet of fava beans after they reach a certain weight, turning their meat from tender to firm and highly sought-after by restaurants and traders alike.

Driven by a shared passion for fish farming, Diep and Tam began cultivating carp over five years ago and soon transitioned to the “crunchy” variety after discovering it during a trip to Hai Duong. Their decision to invest in this method led them to redesign their fishponds and secure a stable fava bean supply. Their process starts with raising the carp to a weight of 1-2 kg, then moving them to another pond to feed exclusively on fava beans for eight months, achieving the desired texture and quality.

Their fish are in high demand, eliminating the need for market trips; buyers come directly to them. In 2023, they produced around 10 tons of "crunchy" carp, generating over 1.8 billion VND in revenue, although expenses halved their net earnings. To maintain fish health over a lengthy growth period, especially during dry seasons, they use biological agents to purify the pond water, control pH levels, and prevent diseases common to carp, like fungal infections and parasites. They also use neem leaves for natural parasite control and adjust water chemistry using lime.

Their venture has gained recognition, with local agricultural departments highlighting their success as a model for other farmers. Today, their farm has become a point of interest for visitors and aspiring farmers, as they share the knowledge and skills they've accumulated through both practical experience and expert training. Their success in this niche market demonstrates the potential of specialized, high-quality fish farming in remote areas of Vietnam.
