Fish Corp collects and presents the environmental data you need to decide whether conditions are right for fishing. Rather than relying on gut feeling, we combine real-time and forecast data into a single view so you can identify productive windows before you leave home.
The primary focus is sea trout in coastal and estuarine environments, with support for Atlantic salmon as well. The platform is built to grow — additional species and data sources can be added over time.
Sea trout (Salmo trutta) are the primary focus. Anadromous — born in rivers, they spend years at sea before returning to spawn. Feeding windows are short and tied tightly to tidal movement, low light, and solunar peaks. Night fishing in estuaries and river mouths is classic. Key season: late spring through autumn.
Atlantic salmon (Salmo salar) migrate from ocean feeding grounds to spawn in their home rivers. They stop feeding once in fresh water, so the goal is to trigger aggression rather than hunger. Best conditions are a rising, clearing river after rain. Prefer cooler water than sea trout.
Each factor below influences fish behaviour in a different way. No single metric decides the outcome — it is the combination that matters. A falling barometer + flood tide + overcast sky + correct water temperature is a session worth making.
Water temperature governs fish metabolism and feeding drive. Cold-blooded fish are directly influenced by the water around them.
Tides drive currents that concentrate baitfish and trigger predatory feeding. Understanding the tidal cycle helps you find the right window.
Barometric pressure affects fish swim bladders and therefore their depth preference and feeding drive.
The moon controls tidal amplitude and influences fish feeding rhythms through solunar cycles — peak feeding times tied to the moon's position.
Wind stirs the surface, reduces fish wariness, and pushes baitfish — and the predators that follow — to specific areas.
Rain changes river levels and salinity gradients, directly triggering or pausing migration runs.
Light penetration affects visibility in the water column and fish confidence. Low light brings fish into shallower water.
Salinity gradients in estuaries attract migratory fish as they transition between salt and fresh water.
