ABSTRACT
The study empirically examined the comparative analysis of the effects of potato fish feed and
orange fish feed on growth of fishes. This is true because all food processing industries generate
waste of varying nature in significant quantities. Managing this waste so as to minimise its impact
on the environment is the prime concern. The concept of waste has undergone much change in
recent times, with the focus being on utilising waste materials as inputs for the generation of new or
reusable products. Vegetable and fruit waste are generated in significant quantities and are easily
available at a minimal charge. The comparative utilisation of these wastes as a dietary ingredient
was assessed employing the Labeo rohita fingerlings as the test species. The study was conducted
over a period of 60 days. Orange peels and potato peels were characterized, and then formulation
of orange peel feed (OPF) and potato peel feed (PPF) was carried out. Market common fish feed
(CFF) was taken as a control. The three test diets were designated as CFF, OPF, and PPF. Feeding
was done once daily. The parameters of the water quality, such as dissolved oxygen, water
temperature, pH, total alkalinity, total hardness, calcium hardness, magnesium hardness, and
growth response were monitored at fortnightly intervals. The quality of water was maintained by
periodic partial replenishment over the period of study. At the termination of the trial, a higher
growth response was recorded in the PPF treatment. The initial and final weight and length of fishes
was recorded. The results show significant growth in PPF and OPF, with brighter body scales than
the other two feed. Fishes were very healthy and normal throughout the study period, indicating no
adverse effect on their health. No infection whatsoever was noted during 60 days of the
experimental period. One of the recommendations made was that potatoes and oranges should be
incorporated into fish feeds in order to reduce the cost associated with the production of farmed
fish as a part of efforts to contribute to the alleviation of food insecurity, hunger and poverty.
