Conservation Status

Population Analysis

  • For the 31,420 species in the Class Actinopterygii (Ray-Finned Fishes), we average 66.73 observations each in our database; for the Flathead Grey Mullet, we have 400 observations. Compared to other species in this Class, this species is somewhat common.
  • A two-sample t-test can be used to determine whether the trend in observations of the Flathead Grey Mullet is the same as the trend in observations of Actinopterygii. Is this species just as common, as a proportion of all observations, as it once was? The answer is no, changes in observation rate of this species significantly differ from changes in observation rate of its Class. (t=8.998, p<0.001)
  • How do observation rates of the Flathead Grey Mullet differ from those of Actinopterygii? To answer this, we examined the percentage of observerations for Actinopterygii that were observations of the Flathead Grey Mullet each year. We then correlated this percentage with observation year. If observations of the Flathead Grey Mullet are becoming more common relative to other species of Actinopterygii, the correlation should be positive, but if it is becoming less common, the correlation should be negative. In fact, the correlation is negative (r=-.38), with a negative slope (m = -.001), suggesting that the Flathead Grey Mullet may be in decline relative to other species of Actinopterygii. This correlation is statistically significant. (F = 50.44, p<.05)
  • The scatter chart to the right shows the percentage of all observations for Actinopterygii each year that were observations of the Flathead Grey Mullet.

Physical Description

Family Mugilidae:

Distribution: all tropical and temperate seas. Chiefly marine (coastal) and brackish water; some in freshwater (Liza abu only in fresh and estuaries). Spinous (4 spines) and soft dorsal fins widely separated. Pelvic fins subabdominal; 1 spine, 5 soft rays. Lateral line hardly visible when present. Mouth of moderate size. Toothless or teeth small. Long gill rakers. Muscular stomach; extremely long intestine. Vertebrae 24-26. Maximum length about 90 cm. Travel in schools and feed on fine algae, diatoms, and detritus of bottom sediments. Important food fishes.

The family Mugilidae belongs to the Class Actinopterygii (ray-finned fishes) and the Order Perciformes. It contains 17 genera and 80 species. It may be found in Marine, Brackish, and Freshwater environments and is primarily Marine. Members of this family are not used in the aquarium trade. Reproductively, most members of this family are nonguarders. The main mode of swimming of adult fish in this family is subcarangiform. Compared with other fish, the activity level of this family tends to be normal. Members of this family have been dated back to the Oligocene epoch of the Tertiary period. This family may be found from 62° n to 45° s and 125° w to 180° e. Etymology of this family name: Latin, mugil, -ilis = grey mullet
