Taxonomy
editLonchuruswas first proposed as a genus in 1793 by the GermanphysicianandnaturalistMarcus Elieser Blochwhen hedescribedLonchurus barbatusfrom Suriname.[1][2]SubsequentlyL. barbatuswas found to be asynonymof Bloch's 1788 species,Perca lanceolatus.[2]This genus has been placed in thesubfamilyMicropogoninae by some workers,[3]but the 5th edition ofFishes of the Worlddoes not recognise subfamilies within the Sciaenidae which it places in theorderAcanthuriformes.[4]
Etymology
editLonchurusmeans "spear tail" and refers to the pointed, lance like tail ofL. lanceolatus.[5]
Species
editLonchuruscontains the following species:[6]
- Lonchurus elegans(Boeseman,1948)(Blackfin croaker)
- Lonchurus lanceolatus(Bloch, 1788)(Longtail croaker)
Some authorities classify the blackfin croaker (L. elegans) in the genusParalonchurusand treatLonchurusas amonospecific genus.[2]
Characteristics
editLonchuruscroakers have a elongate, slightly compressed body with a long head. They have small eyes and a cone-shape snout which protrudes past the horizontal mouth. There are between 1 and 15 pairs of mentalbarbels,as well as 4 or 5 pores, on the chin. The margin of thepreoperculumis not serrated and there is a notch on the upper angle of theoperculum.Thedorsal finis supported by 10 or 11 spines and between 31 and 39 rays. They have a very long, pointedpectoral finand thecaudal finis pointed too. Theanal finis supported by a pair of weak spins and between 6 and 9 soft rays.[7]These fishes reach a maximum publishedtotal lengthof 32 cm (13 in).[6]
Distribution and habitat
editLonchuruscroakers are found in the Western Atlantic Ocean off the western coast of South America and in theWindward Islands.They are coastal and estuarine fishes found over sand, mud and mixed sand and mud bottoms.[8][9]
Utilisation and conservation status
editLonchuruscroakers are caught as food fish. They are mainly taken asbycatch.TheIUCNhave too little information on the population, ecology, distribution and threats ofL. elegansand classify it asData Deficient.[10]They classifyL. lanceloatusas being ofLeast Concern.[11]
