Eugerres plumieri

[4] During the dry season (January and February) these fish can be found aggregating in rivers and canal outlets, where food and refuge are easier for them to find.

During the wet season (September through November) these fish are commonly found aggregating closer to the Caribbean Sea.

It has a dark grey, forked dorsal fin that is typically composed of nine spines and ten rays.

[5] A 2022 study of striped mojarra suggest that the fish display sexual dimorphism during spawning season, meaning that there is a visual difference between the males and females.

[citation needed] It is a diurnal feeder, meaning that it hunts during the day to differentiate between edible and inedible objects.

[11] This hunting tactic leaves the species vulnerable to predation of bigger fish as it calls for them to bury their face into the sand to extract their prey, causing a lack of visibility to their surroundings.

There are currently no conservation measures in place for the striped mojarra, however, there have been recommendations for better population management in the Ciénaga Grande de Santa Marta (CGSM).

[4] Recommendations to improve the estuaries surrounding Colombia are given with suggestions of inducing spawning to increase the population and biomass of these fish.

[13] A 2019 study regarding the presence of microplastics within fishes of the CSGM has shown that there is a need for greater research regarding plastic pollution in the area.

This study found that 5% of the striped mojarra population within the CSGM have ingested plastic fibers and fragments.

Given that the CSGM has been categorized as an important ecological site and that striped mojarra are commonly fished for economic and dietary value of the local area, more research regarding the role of plastic pollution should be conducted.
