In 1987 we found a juvenile yellowfin tuna, Thunnus albacares (Bonnaterre, 1788), in the stomach of a longnose lancetfish, Alepisaurus ferox Lowe, 1833. Analysis of published information on lancetfish food habits (Haedrich, 1964, 1969; Haedrich and Nielsen, 1966; Parin, 1968; Parin et al., 1969; Fourmanoir, 1969; Grandperrin and Legand, 1970; Kubota and Uyeno, 1970; Legand et al., 1972; Kubota, 1973; Fujita and Hattori, 1976; Matthews et al., 1977) led us to conclude that this was the first record of a yellowfin tuna found in a lancetfish stomach.

Continuous research on the freshwater fisheries industry in East Africa, in common with most other African countries, did not commence until the end of the Second World War in 1945. Before the war some work on the fishes and hydrobiology of the lakes of East Africa had been undertaken by a series of scientific expeditions, which were sent out from Europe, between the years 1896 and 1939. These expeditions usually lasted for only a few months, and the collected data were published by young graduates and undergraduates, including such people as Mr. L. C. Beadle, (lately Professor Beadle of Makerere), Mr. V. E. Fuchs (now Sir Vivian Fuchs) and Mr. E. B. Worthington of Gonville and Caius College,Cambridge. Later. Dr. Worthington became Scientific Secretary to the Scientific Council for Africa, Scientific Secretary to the East African High Commission, and played a very large part in the furtherance of fisheries research and management in East Africa.

The deep-water shrimp were already studied many years ago, but their commercial fishing on large scale, only developed from the seventies. Two Luso-U.S. fishing companies (1966), and a Luso-South African company (1963- 1968), dedicated to the fishing of deep-water crustaceans, including Haliporoides triarthrus species (Araújo, 1973). Also Champion (1973) described commercial catches of Plesiopenaeus edwardsianus, Aristaeomorpha foliacea and Haliporoides triarthrus in the waters of Mozambique. The first Spanish vessels began fishing activity in 1968 (Freitas and Araújo, 1973) but all of these companies captured mainly penaideos on the continental shelf.
