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 sandy coastal areas, lagoons and reef slopes to depths of 185 m, often in large schools (FAO catalogue, 1989). Biological reference Global

  Inhabits sandy coastal areas, lagoons and reef slopes, occurring to depths of 185 m. Often occurs in large schools. (our rendering of what the locator holds, not a quotation)

Seasons

• In Jazan, a Saudipedia article on the Kanna season (2 February 2023), which states no year, says «الشعور» (shuour) can be caught all year. The name covers several species and the source does not say which, so this is not stated for this species alone, and it does not mean the chances are equal in every month.

  The page, dated 02/02/2023, lists الشعور among the groups fishermen can catch throughout the year in the Jazan region. (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 FAO catalogue (1989) says it is caught mostly with handlines and traps, occasionally by trawls and gillnets. A worldwide account, not specific to the Saudi coast. Biological reference Global

Bait

• Natural diet reported by FAO: fish, crustaceans and cephalopods. A practical suggestion to test, not a bait shown to be best: include fish bait in the comparison rather than shrimp alone. 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

• This species is one of the eight in the 2026 study of Lethrinus fisheries on the Saudi Red Sea coast; the abstract states no conclusion specific to it, so what it says about two or three other species is not attributed to this one. 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.
