Cuban gar are currently under research for use in broodstocking, both due to the threatened status of gar species and due to the potentially valuable role of gar in reducing the pressure of fisheries on natural aquatic ecosystems. No implementation of Cuban gar broodstocking for ecological protection

During this phase, teeth also develop. Once separation occurs between the stomach and intestines—increased organ size and complexity, and completely exotrophic behavior has arisen—the larvae are considered “free swimming”. While they are larvae, Cuban gar grow from around 1.5 cm (0.6 in) in

During the attached stage, the larvae develop rudimentary intestines, stomachs, pancreases, and esophagi that help the larvae transition from feeding off the egg yolk to normal feeding, which begins during

Cuban gar typically hunt alone and avoid other members of their species. The exception to this is during spawning season, when larger parties of around 20 gar form to hunt. Sometimes, the groups break up into smaller groups, and two to eight males accompany a female.

Adult Cuban gars are typically around 1 m (3.3 ft) in length, but can grow as large as 2 m (6.6 ft). There is no known variance in length relative to sex. This places it as the second largest
