Mudfish (Clarias anguillaris) fish species information

Scientific Name
Clarias anguillaris

Common Name
Mudfish

Biology
Dorsal spines (total): 0; Dorsal soft rays (total): 60-82; Anal soft rays: 42 - 61. The head is oval-shaped to rectangular in dorsal outline; the snout is broadly rounded (Ref. 248). The eyes have a rather lateral position and together with the relatively broad head, make for a relatively large interorbital distance (Ref. 248). The number of gill rakers on the first branchial arch is subject to much variation, between 16 and 40; it rarely exceeds 40 (Ref. 248). The dorsal fin base is situated close to the occipital process; the dorsal fin always terminates before the caudal fin base and the distance between both is small (Ref. 248). The anal fin originates closer to the caudal fin base than to the tip of the snout; although nearly reaching the caudal fin, it is never confluent with it (Ref. 248). The pelvic fin base is slightly closer to the tip of the snout than to the caudal fin base; it reaches the base of the first anal fin rays (Ref. 248). The pectoral fin extand
