Fishing Gear in the Sondu-Miriu River: Level of Use, Preference and Selectivity Waswala-Olewe M
Fishing Gear in the Sondu-Miriu River: Level of Use, Preference and Selectivity Waswala-Olewe M. Brian, Okot-Okumu James and Abila O. Richard Waswala- Olewe M. Brian Okumu James Abila o. Richard Abstract: Artisan fishers of Osodo beach of Sondu-Miriu River (Kenya) use both traditional and modern gear to catch riverine fish species. This study, conducted between August 2006 and July 2007, revealed that fishers most predominantly used gear were the seine nets (42%) and the gill nets (28%). Other used gear include long lines (14%); fish baskets (9%) and weirs (7%). The selectivity of this fishing gear varied with the developmental stages of the fish to be caught. Non- selective gear caught both targeted and non-targeted species irrespective of size and development stages. The ranking of selective to non-selective fishing gear was the long lines, fish baskets, weirs, gill nets and beach nets at 2%, 11%, 16%, 24% and 32%, respectively. The non-selective fishing gear may have negative impacts on the riverine fish by reducing spawning biomass and lacustrine fish recruitment. These findings underscore the need for greater appreciation, research, and adaptation of appropriate fishing gear to ensure sustainable utilization of the riverine fisheries in Sondu-Miriu River.

Also present in the brackish Lake Mariot near Alexandria, Egypt.” Lates niloticus Ecological Risk Screening Summary U.S. Fish and Wildlife Service – Web Version - 8/14/2012 Status in the United States From Schofield (2011): “Scientists from Texas traveled to Tanzania in 1974-1975 to investigate the introduction potential of Lates spp. into Texas reservoirs (Thompson et al. 1977 [cited by Schofield (2011) but not accessed for this report]). Temperature tolerance and trophic dynamics were studied for three species (L. angustifrons, L. microlepis and L. mariae). Subsequently, several individuals of these three species were shipped to Heart of the Hills Research Station (HOHRS) in Ingram, Texas in 1975 (Rutledge and Lyons 1976 [cited by Schofield (2011) but not accessed for this report]). Also in 1975, Nile perch (L. niloticus) were transferred from Lake Turkana, Kenya, to HOHRS. All fishes were held in indoor, closed-circulating systems (Rutledge and Lyons 1976).” “From 1978 to 1985, Lates spp. was released into various Texas reservoirs (Howells and Garrett 1992 [cited by Schofield (2011) but not accessed for this report]). Almost 70,000 Lates spp. larvae were stocked into Victor Braunig (Bexar Co.), Coleto Creek (Goliad Co.) and Fairfield (Freestone Co.) reservoirs between 1978 and 1984. -
