Lake Victoria’s Nile Perch Fish Cluster: Institutions, Politics and Joint Action

The collective efficiency model contends that joint action is essential for coping with new challenges. This paper discusses how enterprises in the Lake Victoria fish cluster operate, interact and address common challenges facing the industry. It suggests that the lack of effective institutions and the existing power relations explain the inability of the cluster to respond effectively to recent crises. Both the Co-operative Society and the Fisheries Department are weak, whereas the existing welfare based associations merely exploit social capital in sub-ethnic groups.

Integrated coastal zone management in kenya: A case study of the Nyali-Bamburi-Shanzu area.

The Nyali-Bamburi-Shanzu coastal area has some of the richest ecosystems characterized by extensive coral reefs, sandy beaches, and dense mangrove forests. Because of the economic benefits derived from them, the area teems with human population. Traditionally, the area's economy is dependent on fisheries, mangrove harvesting and agriculture. Today, these economic sectors have been overshadowed by the development of the tourism and visitor industry. Rapid growth of population spurred by tourism and other commercial and industrial activities has resulted in urbanization.

Effect of Dietary Protein Level in Fish Feed on the Growth Rate of Nile Tilapia (Oreochromis niloticus L.) Fingerlings

The influence of commercial feeds on growth performance of Nile Tilapia (Oreochromis niloticus) fingerlings was investigated in trial lasting 21 days. 100 fingerlings were maintained in hapa nets in triplicate. Fish feed containing 15%,25% and 35% crude protein(CP) was formul~ted with ingredients including fresh water shrimp, sunflower seed cake and wheat pollard. Fish were fed equivalent 3 % of their wet body weight twice daily at 12 hours interval for 4 weeks.Fish growth parameters (length and weight) were taken after every two weeks.

A Review of Sediment Gas Cycling in Lakes with Reference to Lake Victoria and Sediment Gas Measurements in Lake Tanganyika

Little is known about gases in the sediments or the water column of African lakes. Considering the importance of lakes as life-supporting resources, these are critically neglected areas of limnologic investigation. The cycling of nutrients for food web requirements and maintenance of upper trophic levels, i.e. fish and fisheries, and a basic understanding of ecosystem processes requires a fundamental knowledge of the C and N cycles.

Harnessing Maritime Security And Resource Exploitation: Role Of Maritime Diplomacy In Kenya

Maritime security, despite its common usage, is not an easy term to define because it involves a wide range of concerns. The blue economy forms a large stake of most African nation-states and many have significant maritime security challenges. The study purposed to establish facts on harnessing maritime security and resource exploitation utilizing maritime diplomacy in Africa with a focus on Kenya.

Factors influencing implementation of inland fish farming enterprises in Rongo and Awendo Districts, Migori County-Kenya

This research report provides background information of factors that impede adoption l and implementation of fish farming enterprises on a global perspective cascaded to Kenya with specific cases cited in countries currently leading in fish farming like China, Bangladesh, Japan and'India to those African countries where attempts are being made by government and donor agencies to promote fish farming. Access to good quality and timely information in support of fish farming has been cited to affect the decision of the farmers to adopt fish farming.

Lake Naivasha, Kenya: Ecohydrology to guide the management of a tropical protected area

The present ecological and hydrological state of Lake Naivasha, a tropical freshwater Ramsar site, is reviewed from existing research. The ecology of the lake was formerly regulated by ecohydrological control exerted on the inflowing hydrochemistry by the continuous fringing papyrus, with a full swamp on the inflow rivers' delta. The ecology of the lake since that time has been severely disrupted by alien (or exotic) species invasions, particularly the Louisiana crayfish Procambarus clarkii.

Indigenous knowledge and management systems for marine resources among the Giriama of North Coastal

This thesis presents the findings of a study on indigenous management systems of marine resources among the Giriama people of north coastal Kenya. The central problem of the study was the link between Giriama indigenous knowledge and the management of marine resources. The study was also concerned with how Giriama ecological knowledge can be used to harmonise marine resource management in view of the divergent worldviews held by the indigenous communities on the one and the government and ecological scientists on the other hand.

Fish Diseases in Kenya:Current Status and Future Trends in Changing Environment

Finfish like other animals are prone to infections that limit their growth, reproduction; cause morbidity and mortality; while some are zoonotic. Fish diseases and conditions recorded in Kenya are based on laboratory diagnosis after disease outbreak on farms, research and capture fisheries. Fish parasites reported include ectoparasitic protozoa, endoparasitic helminthes, and parasitic crustaceans. A few microbial infections have been reported in form of acid-fast bacteria, Gram positive and negative bacteria; surface and systemic fungi.

Factors influencing Fish production in Mwea Division of Kirinyaga county, Kenya

Fish contribute 7 billion shillings to the Kenyan economy annually and fish farming requires relatively light labour hence does not increase the work-load of burdened rural women. Fish processing, value addition and marketing also provide excellent opportunities for the development of Public-Private partnerships. Government intervention in fish farming started in 1921 when the colonial government introduced trout, common carp and black bass into the country.
