Attributs

DISTRIBUTION: Lien Faunafri
Colour pattern : Musschoot et al., 2021 .
Common names : North African shad (English), Alzeeria aloosa (Estonian), Sabalo rifeno (Spanish) .
Condition / length-weight relationship : Kartas, 1981 .
Current distribution known : species native to the southwestern Mediterranean coastline in northern Africa. It is apparently still present in the Moulouya River in Morocco plus the Soummam and Sebaou rivers in Algeria, but the landlocked population has not been reported from Lake Ichkeul or the Medjerda and Miliane rivers in Tunisia for more than 20 years .
Distribution_references : Musschoot et al., 2021 .
Food habits / trophic level : while at sea this species feeds predominantly on crustaceans and small fishes, whereas in freshwater adults do not feed and juveniles prey on planktonic crustaceans .
Growth / growth performance : Kartas, 1981 .
Habitat / home range : this species is primarily anadromous, although a handful of unconfirmed subpopulations might be land-locked residents of artificial freshwater lakes. It regularly enters coastal lagoons and rivers, spawning close to estuaries in both fresh and brackish water .
Morphology / anatomy : Kartas, 1981 | Musschoot et al., 2021 .
Reproduction : sexual maturity is reached at 3-4 and 4-5 years for males and females, respectively. Upstream migration takes place from mid-March until the end of May when water temperatures reach 14-18°C. Some individuals migrate back to the sea post-spawning, although many die. Most juveniles migrate downstream to river mouths during their first summer and remain at sea until they mature. In the Miliane and Medjerda rivers, Tunisia, the juveniles migrated seaward in September .
Reproduction_references : Kartas, 1981 .
Size : from 43.5 mm SL (male) to 500 mm SL (female); oldest recorded individual was 9 years old .
