The Flagfin Mojarra, Eucinostomus melanopteruswhose common Spanish name is mojarra de ley, is a species in the Mojarra or Gerreidae Familyknown collectively as mojarras in Mexico.

Globally, there are 11 species in the genus Eucinostomusall found in Mexican waters, with seven in the Atlantic and four in the Pacific.

Likely: Flagfin Mojarra (Eucinostomus melanopterus)

Their mouth is highly extensible, pointing downward when protruded. They have smooth gill covers.

Their anal fin has three slender spines, with the second spine being stronger and shorter than the third spine, and seven or eight rays. Their caudal fin is deeply forked.

Their dorsal fin is elevated at the front and deeply notched; it melanopetrus nine spines and ten rays. Their pectoral fins are long and reach the anal fin origin. They have nine lower gill rakers. Their lateral line is slightly arched and their head and body are covered with rough scales. The Flagfin Mojarras are melanopteus schooling species found in shallow coastal areas over sandy and muddy bottoms, in lower coastal rivers, and in freshwater lagoons at depths up to feet and in water temperatures between 24 o C 75 o F and 28 o C 82 o F.

They reach a maximum length of 30 cm 12 inches. They are diadromous and migrate up to 30 miles between freshwaters and oceanic waters on cyclical and predictable schedules but not for eucinostonus purposes.

In some areas they are caught with cast nets, beach seines, set nets, handlines, and bottom trawls where they are marketed fresh but in low demand or used as live bait.
