Rivulated Rabbitfish
Siganus rivulatus
Rivulated Rabbitfish (Siganus rivulatus) is a venomous marine herbivore native to the Red Sea and western Indian Ocean, now established in parts of the eastern Mediterranean. It grazes algae on rocky reefs, seagrass edges, and nearshore coastal habitat.
Poin identifikasi
- Oval, laterally compressed body with a pointed snout
- Dark brown to olive body marked by many pale wavy vertical lines
- Long continuous dorsal and anal fins each with strong venomous spines
Habitat
Shallow coastal reefs, rocky bottoms, seagrass beds, breakwaters, lagoons, and harbors; commonly in warm, sheltered water with algae growth.
Catatan umpan
Best taken on small pieces of shrimp, mussel, squid, or bread-like dough baits; small algae-based baits can also work. Small soft plastics or flies that imitate filamentous algae or tiny prey are less consistent.
Perilaku
Diurnal school-forming grazer that crops filamentous algae and seaweed from hard structure. It is wary in clear water, feeds close to cover, and can be abundant where introduced.
Peringatan
Venomous dorsal, anal, and pelvic fin spines can deliver a painful sting. Handle with care using pliers or a net; check local rules because it may be invasive or targeted for control in some areas.
Catatan memancing
Use light tackle, small hooks, and minimal weight near rocky edges, pier pilings, and weed beds. Chumming with crushed shellfish or bread can draw schools; set quickly because they nibble and move on.
