colorado snapper
Lutjanus colorado · Lutjanidae · predator
Red snapper of the Pacific rocky shores and reefs, from Mexico to Panama. A good fighter and good eating, it takes natural bait and jigs near the rocks.

everything about the colorado snapper
who is the colorado snapper
Eastern Pacific snapper, from southern California to Panama; unconfirmed records reach northern Peru. Adults live alone over hard-bottom reefs and rocky shores, from 1 to 70 m; juveniles appear in shallow coastal waters and estuaries. It eats crustaceans, other invertebrates and fish. In sport fishing in Mexico and Central America it is fished from boats over rocks and shoals with natural bait on the bottom, jigs and mid-water lures, and also from rocky shores near river mouths. On the first run it dives for the rock. The flesh is highly valued, and the species is also fished commercially.
fun facts
- Juveniles have vertical bars that fade with age, when the fish turns fully red.
- In Mexico, cage farming of this species is being tested.
identification
Body and fins almost entirely red, sometimes with a blue stripe under the eye; juveniles have vertical bars. Weak notch on the preopercle. The Pacific dog snapper is darker, copper to olive-brown, with larger canine teeth and a black edge on the dorsal and anal fins.
where found
Does not occur in Brazil. Eastern Pacific, from southern California (rare north of Baja California) to Panama and the Colombian coast; unconfirmed records to northern Peru.
Habitat: Rocky reefs and hard-bottom shores, shoals and rock edges; juveniles in shallow coastal waters and estuaries.
famous destinations
when to fish
best season
Fished all year. Current and clean water over the rocks matter more than the month.
best time of day
Dawn and dusk. Feeds most at dawn, late afternoon and early evening; by day it stays by the rocks and responds best to natural bait.
what affects the colorado snapper
sensitivity The little bars show how much each factor affects this species. Five full: it feels it a lot.
cold and cold fronts
Cold upwelling shuts down activity.
atmospheric pressure
A front with the sea turning rough hampers bottom fishing.
moon
Strong moons move more water over the rocks; moonlit nights are usually good.
rain
Little effect on the bottom; heavy rain muddies the shore.
water level
Not applicable at sea. The equivalent is current over the shoal.
noise
An anchor and hull knocking on the rock spook fish; anchor upstream and let the bait drift in.
wind
Strong wind makes it hard to keep the boat over the rock.
tide
Moderate current is best; still water is usually slow.
depth
Rocky shores and stones from 5 to 40 m.

accessories

- descender (descompressor) for releasing bottom fish
- alicate
tip from an angler
When you feel the bite, lift the fish in the first few metres: if it reaches the rock, it will cut the line.
rules for the colorado snapper
Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
Conservation: Old global assessment; the species supports artisanal fishing across its entire range.
We found no species-specific rule beyond the region's general rules.
catch and release
catch and release Releasing the fish alive, quickly and with a wet hand. During a closed season it isn't always allowed: what the regulation says applies.
A bottom fish can float up with an inflated swim bladder: use a descender to return it to depth. Do not puncture the bladder.
in the kitchen
White flesh, firm and very tasty; roasted whole, fried or in ceviche.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01202, b = 2.94; FishBase). It's an average: a fat or lean fish can vary by 10% to 20%.

sources and references
The season weights (months), the time of day and the sensitivities (cold, pressure, moon, wind, rain, tide, strong light, murky water and noise) are the app's editorial estimates, based on the literature below and on the field experience of anglers and guides. They are not official data nor a measurement made for this species, and they may vary by region and year. Closed seasons and legal rules appear in the rules section, with the norm and a link.

where each number comes from
The weather comes from three independent global models, cross-checked hour by hour: when they agree, confidence goes up; when they diverge, the band between them shows on the chart. Beyond 16 days, we use the GEFS ensemble of 31 simulations: if 20 of the 31 predict rain, the chance of rain is 65%. Sun and moon are calculated astronomically, with no uncertainty.
The index adds up, weighted for each species: time of day (species curve anchored to real sunrise and sunset), moon (transits, rise and set, phase), pressure (3 h trend and 24 h swing), water temperature (in rivers, estimated from air temperature; at sea, estimated by an ocean model), wind, rain, clouds, tide and the month in the species' cycle.

how accurate the forecast is
Accuracy measured in the reference project (4 regions, 93 days, forecast vs. observed): maximum temperature is off by 0.6 °C on average the next day and 1.7 °C at 7 days; rain of 5 mm or more is detected 76% of the time the next day and 57% at 7 days. Detection isn't everything: the false alarm rate isn't published here yet, and 93 days in 4 regions is still a small sample. We now also measure every day, at the app's destinations:
