who is the white-eye
The white-eye is a small fish of the family Anablepidae, the same as the four-eyed fishes, and reaches 15 cm. It lives in low-altitude rivers on the Pacific slope of Central America, between Nicaragua and the Azuero peninsula in Panama, and many live in brackish water. It does not migrate. It feeds on detritus, algae and, sometimes, on land insects that fall into the water. It is not a sport fish: it appears in commercial fishing and the aquarium trade, and it has already been bred in captivity.
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 white-eye; in the meantime, see the similar species.
fun facts
- It has already been bred in captivity.
identification
Small, elongated fish, similar to a sardine, up to 15 cm. The best guide is the place: low-altitude rivers and brackish waters of the Pacific slope, from Nicaragua to Panama. It lives near the bottom. On the same coast, the Pacific four-eyed fish (Anableps dowii) is a close relative, but its eyes are split into two parts, which sets it apart.

Each card shows the day's index (0 to 100) and, below it, a strip with the index for each hour, from 0h to 23h. from poor to excellent.
Essential profile: the index uses a general fish model (weather, sun, moon and tide), without a season or time of day specific to this species.
where found
Pacific slope of Central America, between Nicaragua and Panama, in low-altitude rivers and brackish areas.
Habitat: Low-altitude rivers, up to 15 meters above sea level, and brackish waters, near the bottom.
rules for the white-eye
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.
It is a small, fragile fish: handle it with wet hands and return it to the water quickly, without holding it for long.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00389, b = 3.12; FishBase (relação peso-comprimento bayesiana, estimativa)). It's an average: a fat or lean fish can vary by 10% to 20%.
