The crucifix sea catfish (Sciades proops) — also known as the Christfish, the crucifix/crucifex catfish, the crucifixfish, or the gillbacker, [2] — is a species of catfish in the family Ariidae. [3]
This fish was described by Achille Valenciennes in 1840, originally under the genus Bagrus. [1] It inhabits marine, brackish and freshwaters ranging from Brazil to Colombia. It reaches a maximum total length of 100 cm (39 in), more commonly reaching a TL of 50 cm (20 in). It reaches a maximum weight of 9 kg (20 lb). Its maximum known life expectancy is 4 years. [3]
The crucifix sea catfish spawns from October–May. [4] It is harvested by commercial fisheries, and its meat is marketed fresh. [3]
Diet
The crucifix sea catfish has an extensive diet, consisting largely of crustaceans such as crabs in the genera Callinectes ( C. bocourti, C. danae, and C. ornatus), Petrolisthes, and Porcellana ( P. sayana); shrimp and prawns in the genera Alpheus, Exhippolysmata ( E. oplophoroides), Nematopalaemon ( N. schmitti), Penaeus ( P. schmitti), and Xiphopenaeus ( X. kroyeri); and isopods. It also feeds largely on eels in the families Muraenesocidae and Ophichthidae, and other bony fish in the genera Anchoa, Aspistor ( A. quadriscutis), Cathorops ( C. arenatus, C. phrygiatus and C. rugispinis), Evermannichthys, Gobioides, Plagioscion, Pseudauchenipterus ( P. nodosus), Stellifer ( S. microps and S. rastrifer), Synbranchus ( S. marmoratus), and Trichiurus. It also feeds on annelid, polychaete and roundworms, as well as ariid larvae, insects, gastropods, and leaves and twigs from terrestrial plants. [5] [6]
