# FishRadar Global Bite Index — daily, by country

A daily "bite index" (0–100) for recreational fishing conditions, computed every night by
[FishRadar](https://fishradar.ai) across ~650 tracked fishing spots in 28 countries, and
aggregated here as per-country daily means plus a global mean.

The index fuses live sea-surface temperature, current, chlorophyll, tide, moon phase,
barometric pressure, wind and waves into a single per-spot score
(methodology: https://fishradar.ai/methodology). All values are FishRadar's own
computations — no third-party data is redistributed.

- **Temporal coverage:** 2026-06-19 → 2026-08-20 (63 days; updated periodically from the nightly run)
- **File:** `bite-index-daily.jsonl` — one row per day: `day`, `global` (mean 0–100),
  `n` (spots scored), `countries` (`{ISO2: mean}`)
- **License:** CC-BY-4.0 — cite "FishRadar (fishradar.ai)"

Long-format CSV (`day,country,bite_index,spots_scored`) in three lines:

```js
const rows = require('fs').readFileSync('bite-index-daily.jsonl','utf8').trim().split('\n').map(JSON.parse);
const out = ['day,country,bite_index,spots_scored'];
for (const r of rows) { out.push(`${r.day},GLOBAL,${r.global},${r.n}`); for (const [c,v] of Object.entries(r.countries)) out.push(`${r.day},${c},${v},`); }
```

What feeds the index, explained for humans:

- Tide timing (the strongest single driver in coastal spots): [how to read tides
  for fishing](https://fishradar.ai/learn/how-to-read-tides-for-fishing/), plus live
  [NOAA tide tables for 51 US fishing spots](https://fishradar.ai/tides/)
- [Incoming vs outgoing tide](https://fishradar.ai/learn/incoming-vs-outgoing-tide/) —
  which half actually bites
- The newest signal FishRadar ships: [FishRadar Ear](https://fishradar.ai/ear/),
  on-device detection of the sounds fish actually make
