ProjectTechnical reports - product by product development from Nile Perch (summary table) 1988
Also available in:
No results found.Since dairy meal is becoming increasingly expensive in Kenya and threatens the fish rearing industry, a systematic study was initiated on the possibility of using aquatic plants and Nile perch silage. The water plants, Azolla niloticus, Lemna perpusilla and Pistia striatotis were tested as a fishmeal for Tilapia zillii and riverine fishes. Low growth rates were achieved in the tilapias. The value of the Azolla protein in fish diet is discussed in relation to dietary requirement in cultured fish. This study demonstrates that the water plant Azolla niloticus together with Nile perch silage as a supplement can be used as a complete diet for cultured fish. It is hoped that the project will help provide detailed information on the nutritional value of the water plant Azolla niloticus and its long-term susceptibility to various inclusions as a complete feed, and conduct least cost feed formulations to make recommendations as to the maximum inclusion levels. -
Book (stand-alone)Nile Perch Fishery Management Plan for Lake Victoria 2015-2019 2015
Also available in:
No results found.The Lake Victoria Nile perch (NP) fishery (fishing and post-harvest activities) is a significant contributor to the social and economic development of the Lake Victoria Fisheries Organization (LVFO) Partner States (Kenya, Tanzania and Uganda). The catch of NP has averaged 250 000 tonnes per annum for the last two decades. During the last decade, the fishery has faced serious problems of overcapitalisation and overfishing and high levels of non-compliance to regulations in the fishing and post-ha rvest sub-sectors. This has led to decreasing stock health resulting in an increased vulnerability of the resource base and suboptimal contribution of the fishery to the lake-side economies. A first specific Fishery Management Plan for the Nile perch Fishery (NPFMP1) covering the period 2009-2014 was developed in 2008 by LVFO. Other initiatives, both national and regional, aimed at reversing the Nile perch stock decline have also been promoted since 2008. The implementation of NPFMP1 and related initiatives has led to some progress in the management of the NP fishery; however gaps and weaknesses are still affecting the sustainability of the fishery and the full expression of social and economic benefits that could be derived from proper management of the fishery. -
No Thumbnail AvailableBook (series)Socio-economic effects of the evolution of Nile perch fisheries in Lake Victoria: a review 1988
Also available in:
No results found.The fisheries of Lake Victoria have undergone very substantial changes in recent years owing, in particular, to the rapid proliferation of the introduced Nile perch (Lates niloticus). There has been intense controversy over the impact of this introduced predator species on the fisheries of Lake Victoria, especially with respect to the ecological disruption caused on endemic species and its possibly adverse socio-economic consequences. The present review of the socio-economic aspects of the evo lution of the Nile perch fishery shows the impact of Nile perch to have been both profound and ambiguous. Globally, the Nile perch fishery has been so far an exceedingly positive development from an economic benefit and food resource point of view. On the other hand, some serious issues warrant careful consideration and further analysis. These relate to the distribution of benefits, especially with respect to the relative role of artisanal and larger-scale fishery operations, and to the fundamen tal question of sustainability. It is suggested that, under proper management, the fisheries of Lake Victoria and the Nile perch fishery in particular, could continue to provide high yields and substantial benefits for the riparian communities concerned.
