divided into press cake and press juice. A so-called tricanter centrifuge
is then used to separate this juice into three phases: an oil phase, a
solid phase, and an aqueous phase (stick water) that contains soluble
nutrients. Press cake and press juice are first created from heated raw
ingredients. After the aqueous phase has evaporated to a high dry
matter concentration, the solid phase is subsequently added back to
the press cake. The press cake is then dried to produce fishmeal. The
first press cake is merely dried till it becomes fishmeal in this less
expensive procedure, similar to how it is done with by-products of the
tuna fishery in the Philippines and aboard certain fishing vessels. This
traditional method is frequently viewed as being overly expensive.
When making livestock feed, rice bran and liquid red meat silage are
combined in various ratios to produce finished goods with various
protein levels. This dry feed can be contained in HDPE gusseted bags
that are moisture resistant.
Feed produced by mixing 1 kg of rice bran with 400 ccs of red meat
silage has 20% protein, 23% fat, and 8.8% ash [11]. Since they
demonstrated no negative effects on growth, blood meal and tuna by-
product meal have been approved for use as formulation feeds in
tilapia aquaculture. It is anticipated that the cost of feed products with
various fishmeal alternatives will decrease with the usage of tuna by-
product meals and blood meals as protein sources in Nile tilapia
farming. Based on the fish's overall performance, BM is an appropriate
protein source to substitute fish meals in young Nile tilapia. The
substitution of blood meal with tuna by-product meal had a substantial
impact on growth and nutrient utilization [26]. The silages are then
delivered to a centralized processing facility in sufficient quantities to
allow for their processing into an oil and an aqueous phase containing
hydrolyzed proteins. A concentrated fish protein hydrolysate with a dry
matter content of at least 42-44% is created by evaporating the
aqueous phase. In the dry feed formulation for ruminants, poultry, and
farmed fish other than salmon, this is coupled with oil providing long-
chain omega-3 fatty acids. Using commercial enzymes, derived
