Fisheries Surveys comprehensive list of fish species available and recognizes 166 species from 15 orders. Species include those from the lower Guinean ichthyo-faunal province and the upper Guinean, Nilo-Sudanian, and Zairian provinces. The Cross River has more fish species than any other comparable West African river basin and presents a rich Ichthyofauna (Teugels et al. 1992). At the present moderate levels of fishing intensity in the study area, no species can be classified as endangered, although the threats caused by specific fishing methods are of concern. 4.10 Other Aquatic Animals This study also included questions asking fisherfolk how often they observed other animals while fishing. The objective was to provide additional information on the abundance of aquatic wildlife. The monitor lizard was the most common creature seen, followed by the otter (Table 4). As expected, manatees and hippos, once Total Adult fishermen Adult fisherwomen 149 common, are now less so. Some shellfish such as prawns Macrobrachium sp. are harvested inside hollow Indian bamboo traps. Crabs, frogs, and toads receive little attention. 5 Recommendations To obtain a good understanding of fisheries, especially to enable PROFA to recommend measures that will prevent the valuable stocks of the Upper Cross River from being over-fished, it is recommended that the fisheries monitoring system that was initiated in March 2001 be carried on throughout the project’s lifespan. In particular, monitoring should focus on beach seines, cast nets, and the catch by fish fences and small hooks. Whenever the catch exceeds the maximum sustainable fish yield, management measures to regulate the particular fishery will be needed. Table 3.
