Calculate Migration Pattern

About the Migration Pattern Calculator

The Migration Pattern Calculator is a scientifically accurate tool that predicts the timing, direction, and intensity of fish migration using peer-reviewed biological triggers: water temperature, photoperiod, salinity gradients, and lunar phase. Built on decades of research from global fisheries science, this calculator helps anglers, conservationists, aquaculture managers, and researchers protect migrating fish during their most vulnerable life stage. Proudly hosted on Agri Care Hub, it supports sustainable fisheries worldwide. Learn more about the biology of fish migration in this comprehensive resource: Migration Pattern.

Types of Fish Migration

Fish migrate for feeding, spawning, and survival. The four major types are:

• Anadromous: Live in ocean, spawn in rivers (e.g., salmon, shad)
• Catadromous: Live in rivers, spawn in ocean (e.g., eels)
• Potamodromous: Migrate within freshwater systems
• Oceanodromous: Migrate within the ocean (e.g., tuna)

Why Protect Migrating Fish?

Migrating fish are concentrated in narrow corridors and highly vulnerable to overfishing, dams, and pollution. Protecting them during migration can increase population recovery by 300–1000% (NOAA, ICES studies).
