External identifiers
  • National species code: 1909 — Marine Research Centre, Jeddah

The national collection-form code is not a unique identifier; more than one taxon may carry the same value. The only stable identifier here is the HUWAT code.

Conservation

No governed conservation assessment is published for this taxon. The absence of a published assessment is not an assessment of low concern.

Distribution

The encyclopedia holds no published scientific distribution records for this taxon.

This section shows source-backed scientific distribution only. Community observations are not listed here and no scientific distribution is inferred from them.

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

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

  • The Environment Agency – Abu Dhabi page says the species has large eyes for feeding at night. A regional behavioural hint from the UAE that makes an evening or night trial reasonable; not proof that any particular night is best on the Saudi coast. Biological reference Arabian Gulf

    They have large eyes for feeding at night. (our rendering of what the locator holds, not a quotation)

  • 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

Bait

  • Natural diet reported by FAO: primarily echinoderms, molluscs and crustaceans, and to a lesser extent polychaetes and fish. A practical suggestion to test, not a bait shown to be best: shrimp or crab meat near the bottom, with squid as a comparison. 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

Spawning (the fish’s biology, not a fishing season)

  • A study of about 277 specimens from the Saudi coast of the Arabian Gulf: maturity indexes indicated spawning in April, May and June. Spawning is a fact about the fish, not evidence of the best fishing season. Measured in a study Saudi territorial waters, Arabian Gulf

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 exploitation-status conclusion specific to it (only a median length at first maturity of 25.68 cm), 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
    Source

    Critical information on the genus Lethrinus from the Red Sea, applications for fisheries conservation and management — Abstract (eight Lethrinus species, Saudi Red Sea coast, April 2022–April 2025) · Scientifically documented
    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. (our rendering of what the locator holds, not a quotation)

Identity and names

  • No published seasonal description specific to this species was found in the sources checked.
  • Best month for line fishing: no Saudi source checked ranks the months. Abundance season, spawning season and legal closure are three separate things.
  • Bait ranking: no Saudi comparative trial was found in the sources checked.

Taxa of the same family. That is a taxonomic relationship, not a statement of resemblance; the encyclopedia holds no diagnostic characters or lookalike relations yet.

Information not yet documented in this record

These fields are not yet documented for this taxon in the encyclopedia. Their absence describes the record, not the animal.

Some of these fields do carry an unapproved draft value, shown with its source under “Information on this species” below. Their absence here means not approved, not absent.
