Pure
sea fish meal is a product made from whole fish, bones and byproducts from the
fish after processing. Brown sea fish meal after cooked, pressed and dried.
Sea
ocean fish meal must have protein indicators such as, freshness, ash, moisture
is always in the limit. Sea Fish is one of the best raw material in the
production of animal feed, poultry and seafood. Fishmeal protein in the sea
always has the advantage over other types is easily digestible protein and
essential amino acids.

Fish is a kind of meat processed from fish, trash fish, whole fish, fish heads
and bones or other by-products from the processing of fish. Currently in
Vietnam there are two kinds of sea fish meal flour mainly from ingredients of
marine fish marine (saltwater) fish and marine powder material from Catfish
(freshwater fish). Depending on the feedstock will obtain two types of marine
fish meal products. The poor quality of fish products we obtain marine fish
powder used as raw material for animal feed, poultry and seafood. With the
high-value fish have been sea food fish meal. Along with the development of
seafood processing technology and marine aquaculture, fish meal processing
technologies growing sea. From the production and processing of fisheries generate
abundant waste materials for manufacturing of marine fish meal.
Sea
Fish is rich in protein products, containing from 55% to 67% of total nitrogen,
of which nitrogen digestion and absorption is 80-95% depending on the
processing technology and original material. Meanwhile digestible protein
sources from plants of only 30-40%.
Sea
of fishmeal protein is the perfect protein because they contain all the amino
acids and is not a substitute for weight ratio of amino acids. Marine fish meal
digestion coefficient higher because many protein containing soluble and
absorbed.

Fish is the most valuable component in aquatic feed and, further, it is a major
component in the diet of predatory fish and shrimp. It tastes delicious and
very good quality, adequate supply of protein with essential fatty acids. If
economic terms, it is the only source of protein in aquatic feed. This is also
similar to the case of salmon. It is a good source of energy and its oil also
has the corresponding components such as vitamins, minerals and other trace
elements. However it has a high phosphorus content and easy to pollute. High
quality sea fish meal is good quality activities in aquatic feed. Fish helps
increase resistance to disease (for animal feed) especially in the early stages
of life. The same may be true for aquatic food.
High
quality sea fish meal has a wide application in aquaculture and commercial
terms can also be achieved if the quality control of raw materials and
processing conditions rigorously. According to growth, intensive aquaculture
using aquatic foods containing powder produced marine fish special, called
marine fish meal LT. They are manufactured by keeping the time between
exploiting short in processing time as possible; keeping ships clean
extraction, preservation and marble raw material through freezing and low
temperatures used in both cooking and drying process of the marine fish meal
production without increasing drying time. Marine fish meal LT has several
advantages compared to other types of marine fish meal; there are also some
advantages similar to shrimp, but this has not been verified. Although marine
fish meal LT lot more expensive than ordinary sea fish meal but the food has
improved conversion efficiency when adding this type of marine fish meal, thus
reducing the cost of feed per unit weight body weight.
Sea
Fish is the best food for fish and crustaceans bone, outstanding quality with
high protein content. However, the poor processing and storage will reduce the
amino acids, lipid oxidation and is responsible for the generation of
anti-nutrients such as histamine and derivatives gizzerosin, quality affects
fish but may not affect to shrimp - which has no stomach acid secretion true
style. These substances and other amine has been discussed by Pike and Hardy
(1994). Chamberlin (1993) noted that salmon have low tolerance for histamine
and gizzerosin, while almost no information on the impact of marine fish meal
to all other species. However, Pike and Hardy (1994) in the UK has confirmed
the use of marine fish meal broken, moldy histamine and tyramine with high
volume, will reduce the growth rate of prawn.
The
addition of fish meal in feed marine fisheries are also some differences,
depending on the species, stage of development of the species would correspond
to diet and nutrition components, respectively. Add common ratio, current limit
from a low of 5% in catfish feed to high 60% of marine fish feed. Generally,
most marine fish powder added are expected to fall by 2000, but there will
still be 40% or more for all species except fish bones salmon and catfish.
Percentage add salmon (30%) and shrimp (25%) do not expect to reach this stage.
However, it depends on the circumstances, this percentage can add increased in
intensive aquaculture but less intensive level of involvement, it can be
reduced.
