    The role of research in sustainable fishery exploitation, management and development (2021)
    Uganda Freshwater Fisheries Research Organisation | Jinja, Uganda
    In:  http://aquaticcommons.org/id/eprint/19646 | 4230 | 2021-02-14 01:40:01 | 19646 | National Fisheries Resources Research Institute, Uganda

    Description: Fishery resources are very fragile to exploitation if the basic biological intricacies of the available stocks are not taken into account. Research enables the formulation of sound strategies and practices aimed at sustainable fisheries exploitation, management and development. The success of research strategies requires complementary mechanisms to enforce specified measures.

    Description: Most fishing operations are characterised by selectivity. This obscuressome qualitative and quantitative aspects of the composition of the popula.tion as reflected in the catch. In otter trawls, apart from the question ofavoidance or escapement at the mouth of the net. the most important partof selection for size of fish is the codend. However, the length of the net,along with the mesh size, determine ease of water passage and thus affectsthe efficiency of the trawl. In addition to mesh size other factors affectingcodend selection include: (1) material from which it is made, (2) weight ofthe catch. (3) duration of the haul, and (4) speed.

    The role of man on the changing fishery potentials of Lakes Victoria and Kyoga (2021)
    Uganda Freshwater Fisheries Research Organization | Jinja, Uganda

    Description: The traditional lucrative fisheries of Lakes Victoria and Kyoga were based on similar multispecies itchthyofaunas. Man's activities on and around these lakes have both directly and indirectly assisted to modify the natural trends and components of the commercial fisheries. The exotic L.niloticus and O.niloticus together with the native R. argentea form the major component of current commercial landings. The total catches are higher but it is not yet clear whether the increase would endure given the fragility of predator/prey systems. The trophodynamics are still modifying and it is not certain how ecosystem function would be influenced. It is, therefore, prudent and desirable to undertake appropriate research investigations in order to guide the multiobjective activities of man on these lakes.

    Description: The combined effects of lack of effective managementmeasures, over-exploitation with destructive fishinggears, and interspecific competition, particularly among tilapiines have had profound effects on the fish stocks of Lakes Victoria and Kyoga. It has been proposed that these have been more important in the decline of the indigenous fisheries than predation or competition from Nile perch.The purpose of this paper is to provide an assessment of the dramatic changes in the fisheries of Lakes Victoria and Kyoga . Both lakes have experienced almost similar changes for which Lates could not have been wholly responsible.

    Description: The fisheries resources of mainland Tanzaniaare comprised of both marine and freshwater sources. The freshwater fisheries, however, are the more important and depend upon Lakes Victoria, Tanganyika, Rukwa, Kitangiri, and other smaller 1akes, rivers, swamps, dams and domestic fishponds. Of these, the Tanzania portion of Lake Victoria, which is about 51% of the whole lake area, is the most important single fishery. Its tot

    Description: The scope of this paper covers two areas. The first part considers the current stock size of Lakes Victoria and Kyoga, Lake Albert, Lakes George/Edward and the minor Lakes. The second part looks at the necessary measures for obtaining essential information on the fish stocks and the water environment. These measures are aimed at improving the National fish yield while maintaining the water quality for the different user interests

    Description: Uncontrolled fisheries exploitation, nutrient loading and the proliferation of water hyacinth appear to be the major factors which would strongly influence future prospects for fish production and biodiversity in lake Victoria. There is, thus, justifiable need to tame these factors in order to sustain sound production and biodiversity levels of the lake

    Description: The only comprehensive assessment of fish stocks in Lake Victoria was undertaken during the period 1968/71 by the UNDP/FAO/EAFFRO. This work established for the first time an order of magnitude for the standing stocks of fish at 248,029 metric tons, in the Uganda portion of the lake, of which 205,592 tons (83%) comprised Haplochromis (NKEJJE). The other dominant species (in order of dominance) included the tilapiines (NGEGE), Baqrus docmac (SEMUTUNDU), Ciarias mossambicus (MUDFISH), Synodontis victoriae (NKOLONGO) and Protopterus aethiopicus(MAMBA), Lates niloticus (NILE PERCH) then comprised less than 0.1% of the standing stock (Kudhongania and Cordone, 1974). Rastrineobola argentea (MUKENE), a pelagic shoaling species, was also rare. About 80% of this standing stock was concentrated in shoreline waters of 0-49 metres deep, mostly within the artisanal fishery zone. The vast open and deeper waters had only about 20% of the standing stock.
