Sustainability-minded seafood shoppers and diners

Features
  • Barcode or menu scan that returns species, farm country, and farming method (open-net, RAS, etc.)
  • 0–100 sustainability score combining escapes, sea-lice load, antibiotic use, and feed source
  • Better swap suggestions for the same dinner (wild Pacific, mussels, farmed barramundi)
  • Watchlist alerts when a frequently bought brand is flagged by investigators or regulators
Why now

Norway's farmed-salmon industry is the country's second-biggest export after oil and is hitting ecological limits, with the article naming specific harms (algae blooms, oxygen drops, escapes) — creating active consumer demand for transparency at the point of purchase.

Signals · overall 7/10
Demand
7/10

Norway is the world's largest Atlantic salmon supplier and the article lays out widely covered environmental harms, driving consumer awareness

Whitespace
7/10

Apps like Seafood Watch exist but don't combine barcode scanning plus origin plus plain-language verdict in one consumer app

Monetization
7/10

B2C subscriptions and B2B licensing to retailers and restaurants are both viable, with seafood procurement sustainability budgets growing

Longevity
8/10

Sustainable seafood is a long-running consumer trend, not a fad, and Norway's industry will continue to set the global baseline

Feasibility
7/10

Species/database lookup plus LLM summary is well within reach for a small team with a labeled product dataset
