Influence of Physiochemical Parameter on Fishing Efforts among Fisher Folks in Kisumu Municipality, Kenya

Abstract

The purpose of this study was to investigate influence of physicochemical parameter on fishing effort in Kisumu Municipality, Kenya. Cross sectional descriptive survey design was used in this study. Households were the unit of analysis. From a study population of 15,179 households, a minium sample of 384 household heads were used, proportionatesampling and systematic sampling were used to select households according to location of study area. Purposive sampling were also used to get key informants. Primary data on socioeconomic factors, dissemination channels affecting utilization of research findings and physicochemical parameters trends affecting fishing effort were collected through questionnaires, key informant interviews, Focus Group Discussions, field observation, and photography. The quantitative data were analyzed using descriptive statistics to establish relationships. Qualitative data were analyzed by creating patterns and themes. Finally, logistic regression analysis were used to establish influence of physicochemical parameteron fishing effort to answer the research questions. The regression output shows physicochemical parameter as measured by number of fishers, turbidity, BOD, and pH are not significant influencer of fishing effort ie Number of fishers (ß=-.158, p.05), Turbidity (ß=.452, p.05), BOD (ß=-.954, p .05) and pH (ß=-.103, p .05). However, temperature (ß=-.1.231, p
