Top 5 Freshwater Fish to Farm in Kerala

We evaluated dozens of species. After two years, we chose Giant Gourami. Here’s why, with honest comparisons.

1. Giant Gourami — Our Pick

Exceptional taste (firm, white, mild). Low feed cost (tapioca, moringa, banana stems). Disease resistant. Premium price ₹350-500/kg. Slow growth (10-14 months). Shop Fresh Gourami

2. Tilapia

Fastest growth (5-7 months). Easy breeding. But muddy taste risk, low price ₹150-220/kg, thin margins.

3. Pearl Spot (Karimeen)

Kerala’s iconic fish. Premium ₹500-800/kg. But very slow (12-18 months), small size (200-350g), sensitive to water quality.

4. Catla/Rohu

Proven polyculture. Large size. But not a Kerala favourite, softer taste, lower local prices.

5. Grass Carp

Eats weeds for free. Large size. But bland flavour, low price, escape risk.

Why We Chose Gourami

Taste: Ranked #1 in blind tastings. Hardiness: 5% mortality vs 22% tilapia in monsoon. Profitability: ₹220-340/kg margin vs ₹90/kg for tilapia.
