Publication Recent Limnological Changes and Their Implication on Fisheries in Lake Baringo, Kenya.(Academic Journals, 2014) Omondi R.; Kembenya E.; Nyamweya C.; Ouma H.; Machua S. K.; Ogari Z.Water samples for physico-chemical analysis for this study were collected monthly for five years between April 2008 and March 2013. Conductivity, temperature, dissolved oxygen and pH was measured in situ using a Surveyor II model hydrolab. Chlorophyll-a concentration was determined using a Genesys 10S Vis spectrophotomer. Nutrients were determined using standard methods and procedures. Analysis of Variance (ANOVA) was used to determine spatial and temporal variation in physico-chemical and biological factors. Principal component analysis (PCA) was performed to establish the correlation of the physico-chemical and biological parameters among sampling stations and to group stations with similar physico-chemical parameters. Both spatial and temporal significant variations (P<0.05) were detected in the concentrations of the nutrients measured during the study.
