Ecology of Decapterus macarellus
| Main Ref. | Randall, J.E., 1967 |
|---|---|
| Remarks | Occurs in the continental shelf (Ref. 7300). Prefer clear oceanic waters, frequently around islands (Ref. 5217). Sometimes near the surface, but generally caught between 40 and 200 m depth (Ref. 9283). Pelagic (Ref. 58302). Usually seen as fast moving schools along the reef edges near deep water (Refs. 26235, 48635, 9773). Feed mainly on zooplankton (Refs. 9283, 9773); and feeds during the day and at night. Inhabits midwaters (Ref. 9773). |
