More fishing pressure? No — the same anglers, better spread.

The fair question about a place where anglers publish and unlock fishing log entries is whether it puts more pressure on the water. We think the honest answer is no. Here is that answer written down properly — what we believe and why, what we build in as hard limits rather than promises, and where the research actually backs us up versus where we are only reasoning.

What is actually being sold

A fishing guide sells earned local knowledge — years of tides, seasons and wasted mornings, compressed into one day on the water. Nobody calls that wrong. A published log entry is the same trade at a fraction of the price, and we are honest up front: fish move, and nothing here promises fish.

What unlocks is a real record: species, method, tide, moon, season and the conditions at the moment of the catch, written down by the angler who was standing there. It narrows a search. It does not guarantee a result, and we never say otherwise.

Why this does not add fishing pressure

Effort is fixed; only location changes

Nobody fishes a day they were not already going to fish. Work, weather, the tide, the boat, the kids — those decide how often a person gets out, not whether an entry is available to unlock. Information redistributes rod-hours. It does not create them.

It doesn't create more fishing — it changes where the same anglers go, instead of everyone stacking the same three famous marks.

Redistribution lowers concentration

The status quo is the concentrated one. A handful of famous, publicly known marks get named in every forum thread, magazine and video, and get hammered season after season, while good water an hour away sits untouched because nobody has a reason to try it.

Spreading the same number of rod-hours across more water is the lower-impact arrangement, not the higher one. That is the change we think we make.

A price is a throttle, not an accelerant

A free post reaches thousands of people in an afternoon. A paid entry reaches only the few who decide it is worth paying for. Cost is the strongest limiter there is on how far a location travels — publishing an entry here is a far slower way to share a location than simply posting it.

Fishing Codex takes a 15% platform fee; payment-processing (Stripe) fees also apply — anglers typically net around 80%.

The angler sets the price. Every barrier that limits how far an entry spreads is a barrier we deliberately kept.

Skin in the game

An angler who publishes puts their name on it. Reviews, reputation and repeat subscribers are the whole business, and they only survive if what they publish keeps being worth unlocking.

An angler who floods their own water kills their own income. The incentive points the same way conservation does, which is the only kind of incentive that holds up over time.

Hard design caps, not promises

Good intentions are not a design. These are the actual limits built into the product, and they hold whether or not anyone is watching.

  • The public map is a fuzzed ~10 km zone. Anyone browsing only ever learns that an entry sits somewhere inside a roughly 10 km area. The real point is never at the centre of it, and the fuzzing is the same for everyone — there is no paying more to see closer.
  • No pins, ever. The public map shows a soft heat glow over listed areas and nothing else. No dots, no exact markers, and nothing to tap through to a precise point.
  • The exact location goes to one person. The real location is released only to the angler who unlocked or claimed that entry, and only inside their own private app. The exact location is never shown on the website at all.
  • Every published entry locks its area. Publishing stamps a roughly 500 m lockdown on that area for about 90 days, free entries and paid entries alike, so nobody else can pile listings onto the same water while it is active.
  • Free claims are capped. Every account starts with 3 free claim slots, and they do not reset each month — free access to another angler's water is deliberately scarce, not a tap anyone can leave running.
  • The angler stays in control. Nothing is published without the angler choosing to publish it, and any entry can be unlisted at any time — which removes it from sale and from public discovery, and ends its area lockdown early.

What we will not claim: that a published entry can never be burned. Whoever unlocks it legitimately receives the real location, and no platform on earth can stop a person repeating what they know. What we can do is make the exposure small, slow and priced — and that is what the caps above are for.

Good water is not a fixed supply

An entry is an observation, not an extraction. Nothing is removed from the water by writing down what happened there, and the fish that made it worth writing down move with the season anyway.

That also means an entry's edge fades naturally. A record of a good day two years ago is worth less than a record from last month, so anglers keep fishing new water and keep publishing fresh entries. Effort rotates rather than parking on one mark forever — and the map keeps refilling, because anglers find new water all the time. There is enough fish in the ocean to share.

Efficiency, selectivity, and what the research actually says

Two things below are backed by published work, and one is only our reasoning. We keep them separate on purpose.

Recreational fishing is a genuine data gap

Fisheries science has a long-standing blind spot around recreational catch and effort. Writing in BioScience in 2004, Cooke and Cowx argued that the lack of global monitoring of recreational participation, harvest and catch-and-release has held back any real understanding of how large the sector is, and estimated that recreational harvest may account for roughly 12% of the global fish harvest.

It is taken seriously by managers for exactly that reason. In the United States, NOAA Fisheries runs a dedicated programme to estimate recreational catch and effort, because those estimates feed the stock assessments that set the rules everyone then fishes under.

Letting a fish go is not the same as it living

NOAA Fisheries defines discard and release mortality as fish that are caught alive and then die after release, and has an action plan aimed squarely at closing the gaps in understanding it and getting better estimates into stock assessments.

The scale depends enormously on the situation. A 2005 review by Bartholomew and Bohnsack, pooling 53 release-mortality studies, reported a median release mortality of about 11% and a mean of about 18%, ranging from 0% to 95% across studies — with where the fish was hooked being the single most important factor, alongside bait type and water temperature.

What we reason from that — and it is reasoning

If you know the species, the structure and the state of the tide before you leave the ramp, you spend less of the day prospecting blind. We think that means less fuel burned, less time spent over dead ground, and fewer fish handled for nothing.

We also think fishing known structure for a known species is more size-selective than casting at random — fewer accidental undersized hookups, and so fewer of the marginal releases the research above says carry real risk.

That is a belief, not a finding. We have not measured it, no study we found measures it, and we are not going to dress it up as science. If somebody measures it and we are wrong, we will say so here.

Take what you need, not what you can

Every bag limit, size limit, season and closed area applies to an entry unlocked here exactly as it applies to a location found by eye. Fishing Codex adds information, never exemptions. Nothing you unlock is a permit, nothing here overrides your local rules, and if the water is closed, it is closed.

A location that gets emptied stops being worth anything to anyone — the angler who published it, the anglers who unlocked it, and the people fishing it in ten years. The self-interest and the right thing to do point the same direction here, which is the only reason to expect either to hold.

One thing we would like to do one day: with anglers' consent, aggregated and anonymised catch records — species, size, method, date, never exact locations — could help fill exactly the recreational data gap described above. We do not do this today. It is an ambition, not a feature, and we will not do it without asking first.
