In the western Region of Cameroon, fresh fish is a little food available. Fish is most often sold in its frozen or smoked form because of the long period it can put in households before being consumed. Smocked or dried fishes are generally attacked by insect pests. In order to limit the losses due to these pests, processors and sellers of dry fishes use chemicals. The aim of the study was to determine the constraints linked to storage of smocked fish. The inventory of the species of smocked fishes was done in 10 camps of fishermen. 210 storage tools were inspected, then characterized and the smocked fishes identified. During this survey, 32 samples of Clarias gariepinus, 25 of Oreochromis niloticus and 16 of Hemichromis fasciatus was collected and put in observation at the laboratory. It appears that 13 species of fishes grouped into 5 families are smocked. The Cichlidae family is the most abundant (43.2%). The basket is the most used storage tool (65%) with the longest storage time (4 days). The rate of natural infestation is high in Clarias gariepinus (89.84%) and Oreochromis niloticus (88.12%). During storage, two species of Coleoptera were identified: Dermestes maculatus (735 individuals) and Necrobia rufipes (117 individuals). O. niloticus records the largest mass of drilling meal (5.92 ± 1.13g) and C. gariepinus the largest mass loss (39.44 ± 3.64g). To limit their damages, populations use 10 chemicals. These insecticides, all dangerous, divided into 3 toxicological classes are not approved in Cameroon.
