To ensure the long-term sustainable use of African Great Lakes (AGL), and to better understand functioning these ecosystems, authorities, managers scientists need regularly collected scientific data information key environmental indicators over multi-years make informed decisions. Monitoring is conducted at some sites across AGL; while others sites, it rare or irregularly in response sporadic funding short-term projects/studies. Managers working on AGL thus often lack critical evaluate gauge...
Lake Turkana, located in northwestern Kenya and south-western Ethiopia, is Africa's fourth largest lake the world's permanent desert lake. The lies a closed basin its limnology, ecology, fisheries are driven by seasonal cycles of flooding from Omo River, which provides more than 90% lake's inflow. Turkana unique ecosystem home to at least 79 fish species (12 endemic), remaining population Nile crocodile, hundreds resident migratory bird species. has considerable resources that contribute...
Fish and other aquatic organisms have been introduced into new environments for various reasons. Provision of sports fishery, supplemental to stocks, fill empty niches, control weeds, disease vectors even create a commercial fishery are some the reasons why fish species ecosystems. Lake Victoria Naivasha in Kenya seen several introductions as discussed this paper. In example, include Nile perch, Lates niloticus, tilapia, Oreochromis Tilapia zilii, esclentus among others. The most successful...
In-depth analyses of physicochemical parameters and dissolved nutrients in Lake Naivasha was done during the dry (June 2014) wet seasons (May April 2016). A comparison results made between two seasons. Dissolved oxygen higher to other fresh water lakes within Kenya while relative stability noted physico-chemical (pH, temperature conductivity). Results also show that is phosphorus limited aquatic system with measurements ranging 0.07 – 0.23 mg/l March 0.09 0.83 2016. Nitrates ranged 0.10 0.30...
Abstract A total of 289 fish were analysed in this study, with Caradina nilotica (44%) being the dominant food item their diet, while tilapia (8%) contributed least. Haplochromines, unidentified prey and juvenile Nile perch also observed. An ontogenic shift was observed, C. contributing highest (61.1%) diet fingerlings, but decreasing to 21% adults. 35.7% adults 8.1% fingerlings. This study indicates is a predatory fish, feeding mainly on , haplochromines, tilapia, other materials.
Restocking of fish in Small Water Bodies (SWBs) is one the technologies that can be used to enhance fish-food production for post Covid recovery and growth food security, national development. The current study aimed at assessing socioeconomic impact stock performance restocked Nile tilapia fingerlings SWBs 15 counties Western Central regions where Aquaculture Business Development Programme (ABDP) implemented. employed both primary secondary data from socioeconomics, environmental...
Coptodon zilli and Micropterus salmoides were introduced into Lake Naivasha in 1929 1959, to boost the fisheries for recreational fishing respectively. The population of two fish species lake has been declining making it necessary assess selected growth aspects inform management policy recovery establishment their populations. Length-weight relationship, condition factor, sex ratio length at first maturity studied from October 2016 November 2018. A total 303 samples; 193 C. 110 M. studied....
Turkana County's fisheries sector, which is entirely dependent on Lake Turkana, vital to the county's economy. The Fisheries Sector in County supports 1,500 households directly and 1,100 indirectly. Despite its economic social importance, sector faces numerous challenges such as high post-harvest fish losses, uncoordinated development approaches, over-exploitation of some lake areas weak links between research, management, other players. Furthermore, since start devolution 2013, has been...
Nile tilapia Oreochromis niloticus (L.) is a recent re-introduction in Lake Naivasha and one of the fish species that has crossed into Oloidien. This study assessed compared population characteristic O. under different physicochemical conditions water L. (main) Samples for selected quality parameters fisheries data from catch survey were collected between 2017 2018. Results indicate highest conductivity levels recorded 2018 as 2916 ±11.30 μScm-1 282.33 ± 4.33 Oloidien respectively. Mean...
