Developmental trait (?) | Spawning References: South Carolina Department of Natural Resources (2015) Hogchoker. [Online] Available at: https://www.dnr.sc.gov/swap/supplemental/marine/hogchoker2015.pdf (Accessed: 24 July 2024). Comments: Spawns in various salinities and temperatures, mostly in moderately saline (10-16 ppt) waters at about 25 C. Larvae move upstream into fresh water after hatching. Eggs are pelagic but less buoyant in lower salinities. |

Comments: They mainly feed on small aquatic insects and invertebrates. |
