everything about the redeye bass
who is the redeye bass
The redeye bass is a centrarchid and reaches 47 cm and 3.7 kg. Native to the southeastern United States, in the Savannah and Chattahoochee river basins and the Mobile Bay basin, it was introduced to Puerto Rico, where it is exotic. It lives in rocky rapids and pools of small to medium streams and rivers, and also in headwater streams. It spawns in shallow water, in defined pairs. It is a sport fish and also a subsistence fish.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the redeye bass; in the meantime, see the similar species.
fun facts
- The row of dark spots along the middle of the body is partial or missing in 76% of specimens.
identification
Sturdy-bodied black bass. The species' mark is red on the rear half of the second dorsal fin, the caudal and anal fins, and along all the rays of the pectoral fins; in its relatives in the same group, this tone is green, greenish-yellow or orange and covers a smaller area. The row of dark spots along the middle of the body is often partial or absent. It has a patch of teeth in its mouth.
where found
Southeastern United States, in the Savannah and Chattahoochee basins and Mobile Bay basin; in Puerto Rico it is exotic.
Habitat: Rocky rapids and pools of small to medium streams and rivers.
rules for the redeye bass
Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
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.
The fin spines cut, and the black bass has a patch of teeth in its mouth: hold it carefully by the jaw and return it promptly.
in the kitchen
It is used for subsistence, so it is eaten by the people who catch it.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01047, b = 3.05; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.

sources and references
Essential profile: size, length-weight, depth, countries and conservation come from FishBase and the cited regulations, and the texts were written from those sources. Season, time of day, sensitivities, technique and baits and lures are not included yet, because we did not find a good source for this species.

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:
