Orange-striped emperor

Fishing and seasons

Abundance season, spawning season and legal closure are three separate things. Each line carries its kind of evidence, its region and its source; what is not documented is said to be undocumented.

Habitat and diet

• Inhabits seagrass beds and sand and rubble areas of lagoons and reefs to depths of around 30 m (FAO catalogue, 1989). Biological reference Global

  Inhabits seagrass beds, and sand and rubble areas of lagoons and reefs to depths of around 30 m. (our rendering of what the locator holds, not a quotation)

Time of day

• General handlining guidance from an FAO manual: the best times are usually early morning and late evening. It is general advice, not specific to this species and not backed by a Saudi study; the same manual advises also watching the current, the bottom and the presence of bait fish when choosing where to fish. General guidance — not species-specific Global

  States that, as a general rule, the best times for handlining are early in the morning and late in the evening; the right time also depends on the species and place. (our rendering of what the locator holds, not a quotation)

Gear

• The catalogue says it is caught mostly by traps and shore seines, occasionally by gillnets, handlines and trawls. A worldwide account, not specific to the Saudi coast. Biological reference Global

Bait

• Natural diet reported: crustaceans, molluscs and echinoderms. A practical suggestion to test, not a bait shown to be best: shrimp or squid near the bottom. A natural diet does not by itself prove the best bait, and no Saudi comparative bait trial was found. Practical suggestion to test — not shown to be best Global

Fishery status

• A 2026 study of eight Lethrinus species in Saudi Red Sea fisheries: L. obsoletus is below the 40% spawning-potential-ratio threshold but only slightly above safe biological limits, according to the abstract. The authors recommend species-specific minimum landing sizes, selective gear and stronger enforcement. Measured in a study Saudi territorial waters, Red Sea

  Exploitation exceeds the reference limit in three species; L. lentjan has spawning-potential-ratio values below 22%; L. mahsena and L. obsoletus are below the 40% threshold; recommends species-specific minimum landing sizes, selective gear and stronger enforcement.
