We made a map of 40+ Sustainable Fish Farming Startups 🐟

(Attracting over $180Mn in funding!)

With 90% of wild fish stocks fully exploited aquaculture now produces more fish than wild fishing

.... making sustainable fish farming critical for global food security.

We grouped startups into three categories:

🦗 1. Alternative Feed - Insect proteins, microalgae, and sustainable feed alternatives that replace wild-caught fish in aquaculture diets.

💊 2. Fish Health and Disease - Vaccines, probiotics, and treatments that keep farmed fish healthy while reducing antibiotic use.

📊 3. Fish Farming / Monitoring - Smart sensors and data platforms that optimize feeding, track fish health, and automate farm operations.

Are you a fan of these sustainable seafood solutions? Did we miss anyone?
