Abstract: Chrysichthys nigrodigitatus, commonly known as the Jawfish, is classified in the Claroteidae family. It is present in tropical West Africa in lagoon and continental waters. It is easily recognizable from the other two species (C. maurus, and C. auratus) by its larger size and silvery gray coloration. There is a pronounced dimorphism between mature and immature individuals. Mature males can be recognised by their swollen heads and enlarged mouths, while mature females are overweight. Chrysichthys nigrodigitatus is a euryhalin fish with a preference for oligomesohaline waters. Chrysichthys nigrodigitatus has an omnivorous, insectivorous diet. Sexual maturity is reached in Chrysichthys nigrodigitatus around the age of 2 to 3 years. This fish is the subject of an intense fishery exploitation that threatens the stocks. Its domestication is the ultimate solution for its preservation in order to provide fish for consumption and reduce the import of frozen products.
