Kelp Bass
Kelp Bass (Paralabrax clathratus) is a saltwater species. The first thing to check: the third, fourth and fifth dorsal spines are all about the same length — the definitive separation from a barred sand bass. The look-alike to rule out is Barred Sand Bass: on a barred sand bass the third dorsal spine is clearly longer than the fourth and fifth, and the bars are darker and more regular.

How to identify a Kelp Bass
- The third, fourth and fifth dorsal spines are all about the same length — the definitive separation from a barred sand bass.
- Brown to olive with pale cream blotches that form irregular, broken vertical bars.
- No dark spots scattered over the body or fins.
If you would rather not work through a key on a wet deck, photograph the fish and let the app name it — you get the common and the scientific name back, and the record is filed before you release.
Fish it is mistaken for
| Species | How to tell them apart |
|---|---|
| Barred Sand Bass | On a barred sand bass the third dorsal spine is clearly longer than the fourth and fifth, and the bars are darker and more regular. |
| Spotted Sand Bass | Spotted sand bass are covered in distinct dark spots over the body and fins, which a kelp bass never has. |

The conditions that matter
Calicos live in the kelp and are ambush feeders, so the day is decided by structure, current and light rather than by weather at the surface. A moving tide through a kelp edge at first light is the pattern; slack water in bright sun is the hard one.
Global Fishing League records 18 weather and water readings against every catch automatically — tide stage, barometric pressure, water temperature, salinity, dissolved oxygen, chlorophyll, swell, current, moon phase and more, taken at your GPS position at the moment you log the fish. Over a season that turns a hunch about kelp bass into a pattern you can read.
See every reading recorded with a catch, or the guides to what each reading means.
Size limits, bag limits and seasons
Size limits, bag limits, slot limits and seasons are set by your state wildlife agency — and for many offshore and migratory species by federal regulators — and on many waters they differ from the statewide rule. They also change between seasons. Check the current regulations for the exact water you are fishing before you keep a fish — we do not republish limits here, because a number that is a season out of date is worse than no number.
What the app does do is make your side of it accurate: every catch carries a length measured from the photograph, a GPS position and a timestamp, exportable if you ever need to show your work for a tournament or a record claim. It is also what a Global Fishing League entry is built from — a record that verifies itself, without publishing where you caught the fish.
