LOCAL FLOATING FISH FEED PRODUCTION

Most of fish feed pellet in market is
low in terms of water stability and
easily swell when it is immersed in
water. Thus, the soluble vitamins
and minerals will be easily leached
out from the pellet. These will lead to the nutrient deficiency and
environmental problems in fish
tanks or ponds. Therefore, a study
was conducted to minimise the

degree of swelling and mineral
leaching while the floating time is maximised. For these purpose
several formulations of fish feed
were made and tested. The
formulation was based on common
resources such as corn flour, soy
flour and tapioca flour for basal or energy feed stuff and fish meal, soybean meal azolla meal as the protein source other additives such as vitamines and some suplement to balance the fish feed. To get water stability which is better
floating time and lower leach
ability, palm oil stear in was added
as a main subject compound for
this study. Statistical method, D-
optimal crossed design of response surface methodology was used for the analysis and
optimisation of the properties of
fish feed pellet produced. In the
statistical analysis, the physical properties such as degree of swelling, leaching and floating
ability were chosen as the
responses where as pellets
composition and processing
temperature as the independent
factors. The result shows there is a relationship between fish feed
formulation and properties of fish
feed pellet produced. The optimum
of the floating time, leach ability
and stability of fish feed pellet also
can be obtained. For your floating local fish feed call us on 08032861326 for help and consultancy.
