In the past there was a tendency to seek economic cooperation among one's local matrilateral and bilateral kindred. Like the Lozi situation described by Gluckman (1941), the economic activities of Luapulans are so varied that a wide deployment of manpower is required. In any one situation there are always some local kinsmen from whom one may choose helpers, and widely dispersed clansmen amongst whom one can travel and live in order to harvest or collect different resources to offset seasonal shortages at home. Permanent residence in one locality is based upon the mobility of kin who can be sent to garner varied resources in different areas. For example, young men may be sent to live in fish camps on islands in the swamps or river during the months of May, June, and July, or November through March. Commercial fishing of the prized pale (Tilapia macrochir) takes place from August through November and, at this time, young men devote their energy to fishing in the main river. Older men, on the other hand, even today usually fish in nearby waters for immediate consumption only (see Figure 3).
