Description:
Synodontis denticulatus is an endemic from the
middle Lufira Basin and its associated tributaries
and lakes. The species shows close morphological resemblance
to Synodontis
greshoffi and Synodontis
unicolor, which are widespread Congo Basin and
Bangweulu-Mweru endemic species, respectively. However,
it differs from both S. greshoffi and S.
unicolor by its non-villous skin (v. villous
skin), strong and numerous serrations on the posterior
margin of the dorsal spine (v. weak and fewer serrations),
weak and few serrations on the posterior margin of
the pectoral spine (v. strong and numerous serrations),
relatively short maxillary barbels (v. long) and its
small maximum standard length (89.1 mm LS v. 148.0
and 190.7 mm LS respectively). A DNA barcoding study
(coI, mtDNA) revealed that S. denticulatus
forms a distinct genetic clade with a genetic distance
of 2.18% with S. greshoffi and 0.84% with
S. unicolor. Synodontis denticulatus
is caught regularly and abundantly as a by-catch in
the gillnet fisheries in the middle Lufira lakes.
Owing to its small overall size and large bony head,
the species has usually no real commercial value but
is an important food fish for the fishermen's families.
AquariumCare: In
groups of 5 or more individuals; minimum aquarium
size 80 cm. A very social Synodontis. Diet:
Oviparous, Feeds mainly at night on insects, crustaceans
and plant matter. A good diet of a good quality flake
food, tablet food, frozen bloodworm and live food
such as daphnia should suffice. Etymology:
From the Latin denticulatus, meaning denticulate or
with small teeth, a reference to the well-marked and
quite numerous denticles on the posterior margin of
the dorsal spine of this species.
