Sustainable production of aquatic organisms can be obtained by formulating and producing low cost, low polluted and nutrient rich high quality artificial feeds. Like terrestrial animals around 40 essential nutrients are required by the aquatic organisms which includes protein, carbohydrate, fatty acids, vitamins, minerals, growth factors and other energy sources essentially for maintaining growth, reproduction and other normal physiological functions. The variation in the nutritional req uirements can be identified with warm water or cold water, finfish or shell fish and marine water or freshwater species. Successful production of good quality fishes can be achieved by feeding the fishes with nutrition ally balanced feeds. There are a lot region .

Introduction:
Sustainable production of aquatic organisms can be obtained by formulating and producing low
cost, low polluted and nutrient rich high quality artificial feeds. Like terrestrial animals around 40
essential nutrients are required by the aquatic organisms which includes protein, carbohydrate, fatty
acids, vitamins, minerals, growth factors and other energy sources essentially for maintaining
growth, reproduction and other normal physiological functions. The variation in the nutritional
requirements can be identified with warm water or cold water, finfish or shell fish and marine water
or freshwater species. Successful production of good quality fishes can be achieved by feeding the
fishes with nutritionally balanced feeds. There are a lot of Aqua feed industries in Mymensingh
region. Fish requires higher protein in their diet. Feed stuffs of vegetable origin are lower protein
content compared with animal origin.
Our Fisheries department organized a study tour for us. The place of the study tour was Shushama
Feed Ltd in Churkhai, Mymensingh District. This is the tour of Fish Nutrition course. During our
study course “Fish Nutrition” we have studied about different Fish feed and their required nutrients
component and their measures. We have gain practical knowledge of the Fish Feed Industry and
Fish Nutrition laboratory by this tour. This learning will help us for the future in the field of
Fisheries.
Objectives:
➢ To gather practical knowledge of the laboratory techniques of fish feed industry in our country
➢ To connect with the fish feed producers in real world.
Journey time & Study tour:
We students of level-3 semester-2 were looking forward to visit a Fish Feed industry in
Mymensingh district namely Shushama Feed Ltd from Bangamata Sheikh Fojilatunnesa Mujib
Science & Technology University, Melandah, Jamalpur. We had pre-planned everything. We
started our trip by two buses at 6.30 am from our campus. Our respectful course teacher Partha
Sarothi Das guide us in this tour. Our beloved chairman sir Dr. Abdus Sattar and Md. Forhad Ali

also accompanied us. We took our breakfast in Mymensingh at 8.30 am and we reached Churkhai
at 9.30 am.
Discussion:
Upon arriving we were cordially welcomed by the manager, engineer and scientific officer of the
company. They give us a brief description about the industry and how it’s work. It is a feed making
industry which work with fish feed and poultry feed. We were 65 in number so we divided into
three groups and have a tour around the industry. The staff there were very friendly and guided us
eagerly. The industry is divided into three parts, The laboratory, Storage, and Machineries.
The Laboratory:
We first visit the laboratory where all the raw materials and feed are tested. The Laboratory was
consist of two rooms. The raw materials are tasted in here to see there protein, lipid and moisture
content We saw the following laboratory equipment in there:
I. Electric balance: It is very important to know the exact sample size before performing any
experiment. It is used to determine the weight of the sample.
II. Kjeldahl apparatus: Kjeldahl Apparatus is used to determine organic nitrogen (n2) and
protein contents in chemical substance. This estimation is done by Kjeldahl digestion
method. A kjeldahl apparatus have two parts: Digestion unit and Distillation unit.
III. Grinder: It is used for blending or grinding large pieces of experimental materials.
IV. Desiccator: Desiccators are sealable enclosures containing desiccants used for preserving
moisture-sensitive items such as cobalt chloride paper for another use. A common use for

4. Page 3 of 7
desiccators is to protect chemicals which are hygroscopic or which react with water from
humidity.
V. Soxhlet Apparatus: The Soxhlet extractor is used for liquid-solid extractions when the
compound to be extracted has limited solubility in the chosen solvent and the impurities are
insoluble.
VI. Hot Air Oven: It is used for determination of moisture content of any substance wheather it
is a sample of food or raw material.
VII. Centrifuge Machine: A centrifuge is a machine that uses centrifugal force to separate the
contents of a sample based on their density. When the centrifuge spins, it creates a strong
centrifugal force.
VIII. Crucibles: A vessel of a very refractory material (as porcelain) used for melting a substance
that requires a high degree of heat. It is used to keep the sample in the oven or desiccator.

IX. Refrigerator: It is used to cool and store substances at low temperature.
Samples used in the laboratory:
➢ Sinking feed
➢ Floating feed
➢ Raw materials of feed
Storage Area:
This was the biggest section of the industry. All kinds of raw materials for feed and sacs of
prepared feed were stored in there.

Some of the raw materials we saw in there are given below:
Maize: It is basically corn dust. The feed made by Sushama Feed Ltd. contains 50% maize. The
protein content in the maize is determined in the laboratory and then the feed is made.
Wheat bran: Wheat bran is a source of fiber. It is used to increase the gluten content in feed.
Poultry meal: It is made by crushing or grinding dried fish.
Limestone Semolina: Mainly used in poultry feed not in fish feed.
Soybean: Soybean meal is made from grinded soybean. Two kinds of soybean meals are made:
1. Low protein: Which contains 40-42% of protein.
2. High protein: Which contains >45% of protein.
Rapeseed: Rapeseed contains 40-42% protein.

Rice polish: Rice polish is a by-product of rice obtained in the milling operation of brushing the
grain to polish the kernel. Rice polish is used in feed to give them a certain flavor.
Overview:
According to the manager they make two kind of feed; Floating feed and Sinking feed. Sinking
feed is the most in demand. The industry sells 200 Ton feed per day. One unit of feed contains 25
kg which will cost 1478 M.R.P. Each batch has an expiry date of 2 months. After making the feeds
they are tasted in the laboratory and if they seem to have the standard amount of nutrition they are
sent to the buyers.
Conclusion:
Manufactured feeds are an important part of modern commercial aquaculture, providing the
balanced nutrition needed by farmed fish. Visiting Sushama Feed Ltd. has established a link
between our academic knowledge and its practical application. From this study we acknowledged
how important it is to know the nutritional value of the feed. This particular study will help us to
become more professional in fisheries field in future. This study tour has inhanced our knowledge
about fish feed and fish nutrition.
