ABSTRACT
The Lake Victorian Nile Perch (Lates niloticus) industry in Kenya is the most
important in the fisheries sub-sector and generates significant levels of revenue to
the national economy besides creating employment opportunities along the value
chain. In 2012, fish production from Lake Victoria-Kenyan waters was 118,992
metric tons with an ex-vessel value of USD 136 million. Information on the
utilization of by-products and cleaner production is very important as the industry
plays a significant role in the economic and social development in the country. It
improves and attracts export market. The main products from processing are chilled
or frozen NP fillets exclusively destined for the export market. The processing
further produces vast amounts of by-products. The aim of the study was to find out
factors that influence the utilization of by-products and Cleaner Production in the
Nile Perch processing industry. A descriptive study design was employed to carry
out the study qualitatively. The target for the study were the employees and traders
of three NP fish processing plants based in Homa Bay, Kisumu and Nairobi in
Kenya. The study was carried out between the months of May 2012 to February
2013. The methodology involved the use of structured questionnaires and
interviews to a sample of 254 study subjects from a population of 660.The objective
of the study was to find the factors that contribute or hinder the utilization of byproducts
and the Cleaner production in the industry. Data collected was analyzed
using SPSS and EXCEL computer packages and the results were presented in form
of figures and charts. The results of this study indicated that the yield on skin-on
fillets was at 50%, skinless fillets 42% and for headless and gutted fish 69%. There
were several by-products produced by the Nile perch fish processing plants, and
these included fish maws, fish frames, skins, scales, viscera, fish pads and
proteinous thick liquid. Cleaner production was employed by the Nile Perch
processing plants to a large extent but had not been documented. The NP processing
plants greatly influence the utilization of by-products. Cleaner production practices
were implemented in the NP processing plants and there was a statistically
significant relationship between utilization of by-products and Cleaner production
in NP processing plants in Kenya. Various factors were tested to have negative
significant association with utilization of by products that included lack of expertise
with a correlation of -0.716, lack of appropriate technologies with -0.874, financial
constraints with -0.624, lack of markets, -0.559, lack of raw materials with -0.547
and poor management practices with -0.738 correlation coefficient. Utilization of
by-products and cleaner production can help reduce the reported negative effects of
improper waste disposal of thick waste by the plants to the environment, human and
animal lives. Measures to improve the CP included controlling the valves, use of
foot operated taps, use of water holding tanks and bins during processing, use of
adjusted pipes, meter recording, supervision, use of high pressurized pipes as well
as the use of low pressure pipes. It is therefore recommended that all Nile Perch
processing plant should adopt measures that enable successful utilization of the byproducts
and integrate CP in their operations.
