Die Karanteen (Crenidens crenidens) is 'n vis wat voorkom in die westelike Indiese Oseaan, die Rooisee en aan die ooskus van Afrika van Oman tot by Durban.
Die vis se kop en lyf is silwer met 'n dowwe reeks donker kolletjies op die liggaam. Die vis word 30 cm groot.
Die vis verkies strandmere en beskermde baaie maar word nie gevind waar die see se soutgehalte laag is nie. Hulle kom voor in skole. Hulle eet krap, wurms en garnale en broei in die noorde van die KwaZulu-Natal kusgebied. Die vis is eetbaar maar word hoofsaaklik as aas gebruik. Die vis moet nie met die Strepie verwar word nie.

Crenidens crenidens és un peix teleosti de la família dels espàrids i de l'ordre dels perciformes.[2][3]
Crenidens crenidens és l'única espècie del gènere Crenidens.[4]
Pot arribar als 30 cm de llargària total.[5]
Es troba a les costes occidentals de l'Oceà Índic: des del Mar Roig i el Golf Pèrsic fins a Durban (Sud-àfrica) i el sud de Madagascar. També se'l troba a la Mediterrània a on va emigrar a través del Canal de Suez.[5]
Crenidens crenidens, the karanteen seabream or karanteen, is a species of ray-finned fish from the sea bream family Sparidae which was described by the Swedish zoologist Peter Forsskål in 1775. It is native to the western Indian Ocean but has colonised the eastern Mediterranean Sea since 1970. It is one of only three species in genus Crenidens, the others being the little known Crenidens macracanthus and the partially sympatric C. indicus.
Crenidens crenidens has an oblong to ovoid shaped body which is slightly compressed. Smaller adults, less than 19.7 cm in length, show a nose like bump in front of the eye. The mouth extends back to the anterior nostril and there are three rows of teeth in each jaw, the upper front jaw has 8-9 brown-tipped incisor like teeth, each bearing five denticulations which give the edge of the teeth a wavy appearance. The inner rows have a few teeth of similar form but the other teeth are granular. The scales finely ctenoid, the scaly cheeks contrasting with the scaleless interorbital region. The dorsal fin has eleven each of spiny and soft rays, while the anal fin has three spiny and ten soft rays. The caudal fin is forked. There are 52-60 scales making up the lateral line.[3][4]
C. crenidens is silvery greenish-blue or olive in colour with darker narrow longitudinal stripes created by dark spots on the scales which are above the level of pectoral fins; the fins are coloured dull yellowish or olive with a dark margin on the dorsal fin and infrequently the axil pectoral fin shows darkish axils. They can grow to 30 cm in length in their native range, although the maximum in the Mediterranean is 20 cm, the more usual measurement is between 10 and 16 cm in length.[3]
Crenidens crenidens is indigenous to the western Indian Ocean from the Red Sea south along the coast of eastern Africa South Africa and has been also reported from southern Madagascar.[5] In 1970 it was recorded for the first time in the Mediterranean in the Bardawil Lagoon (northern Egypt) and has since spread to Israel and to Libya. The most likely route for this species to have followed to colonise the Mediterranean is through the Suez Canal.[3]
Crenidens crenidens is found in shallow coastal water, over sandy substrates which are frequently covered with sea grass.[3] Its main food is algae but it also feeds on smaller invertebrates, such as crustaceans and worms.[5] The eggs and larvae are planktonic.[3] Off the Libyan coast C. crenidens has developed a distinct breeding season from November to February and the fish move away from the coast to spawn elsewhere in March and April. The males attain sexual maturity at 14 cm length and some females reach maturity at around 13 cm to 13.9 cm but for 50% of females maturity occurs at around 15.4 cm length. Fecundity is dependent on the weight of the female and varies from 678 eggs in smaller females to 9,888 eggs.[1]
There were two generally recognised subspecies:
The two taxa occur sympatrically in the Red Sea.[3][6] Recent work has supported the raising of C.c. indicus to species level once more and that a third species which is currently regarded as a junior synonym of C.c. indicus, Crenidens macracanthus, known from only two specimens from the Arabian Sea, is a separate valid species.[7]
Crenidens crenidens is caught all year round in the northern Indian Ocean using trammel nets and beach seines and is consumed fresh, however, in the southern part of that Ocean it is fished mainly for bait.[5]

Crenidens crenidens (Forsskål, 1775), unica specie del genere Crenidens, è un pesce d'acqua salata della famiglia Sparidae.[1]
Questa specie è diffusa nell'Oceano Indiano occidentale, dal Mar Rosso alle coste del Sudafrica. È migrata nel Mar Mediterraneo attraverso il Canale di Suez.[2] Abita aree costiere, con acque calme e fondali melmosi.
La forma del corpo è tipica degli Sparidae: allungata, compressa ai fianchi ed abbastanza alto. La pinna dorsale presenta i primi raggi spinosi. La coda ha il margine bilobato. La livrea è argentea. Raggiunge una lunghezza massima di 30 cm.
Come per le altre specie del genere.
Ha dieta onnivora: si nutre di alghe, vermi, crostacei ed invertebrati.
C. crenidens è oggetto di pesca per l'alimentazione umana ma anche utilizzate come esca viva.
