Although it is known enough of the biology of shallow+ waters shrimps, knowledge of the deep-waters shrimp is still limited. This is due to the fact that: these resources are relatively new and the study of deep waters species is more difficult and expensive. Some biological informations on the main species of shrimp in depth of Mozambique have been collected during investigation cruises (Sports et al., Pacule, 1987) and through sampling carried out on board commercial vessels (DDR fleet) between 1983 and 1986.
