Variety of fish feed ingredients are available in Bangladesh. A major
portion of this ingredients are obtained from different plants.
Different parts of plant body are used as fish feed. Plant origin feed
ingredients are comparatively cheaper than animal origin fish feed
ingredients like fish meal, bone meal etc. and also contains less
protein than those animal origin ingredients. However considering the
economic capability of most of the fish farmers in Bangladesh, plant
origin feeds ingredients are considered suitable for aquaculture. Some common ingredients:
Some
common fish feed ingredients which are originated from plant sources
are- Maize bran, Suji, Rice flour, Rice bran, Rice polish, Wheat flour,
Wheat bran, Sesame oil cake, Soybean grits, Mustard oil cake, Coconut
oil cake, Lentil bran, Molasses etc. Most of the plant origin fish
feed ingredients are obtained from seeds of the plants. These plant
ingredients can be grouped under heading bran, oil cake, flour, and
others. Bran group includes rice bran, wheat bran, lentil bran etc.
whereas oil cake group includes mustard oil cake, coconut oil cake,
sesame oil cake etc. Oil cakes are obtained after processing of oil from
the seeds. Flour group members are rice flour, wheat flour etc. and
other ingredients are molasses, suji etc. Plant origin fish feed
ingredients are mostly of less protein containing ingredients except oil
cakes. Except these oil cakes almost all other plant origin ingredients
are considered as basal or energy supplement (i.e. contains less than
20% protein) such as maize bran (12.20%), rice bran (10.26%), wheat bran
(12.91%) etc. However some oil cake contains relatively high
protein percentages and considered as protein supplement (i.e. contains
more than 20% protein) such as mustard oil cake (30.33%), sesame oil
cake (27.2%) etc. Plant origin fish feed ingredients are varied
considerably in shape and size. They may be powder like or solid
irregular shaped. Feed particle size also varied greatly and as
carnivorous fish species demand a very high level of protein, direct
application of plant origin ingredients is found mainly in carp
(herbivore or omnivore) polyculture farming system. These ingredients
are used in feed industries as raw materials for making high
protein-leveled fish feed by mixing with other ingredients and marketed
in packed condition which are vigorously being used in commercial fish
farms. As many of these ingredients can be made at home and available in
rural or remote areas, for this, fish farmers from those areas used to
feed their fish-stock with these ingredients.
