Introduction
An aquafarm is a place to cultivate fish or shellfish under controlled conditions. Site selection and
construction are crucial factors affecting the operating efficiency of the farm, thereby influencing
initial capital costs, operating costs and level of yield.
As part of our course “Aquafarm Design and Construction” on May 13, 2023, an insightful study
tour commenced at 9:30 AM, led by our respected teachers, Dr. Abdus Satter, Dr. Muhammad
Forhad Ali, and Partha Sarathi Das from the Department of Fisheries. The purpose of the tour
was to visit Zohurul Fish Farm, a prominent fish farm located in the Jamalpur district. This
excursion was organized by the Dept. of Fisheries of Bangamata Sheikh Fojilatunnesa Mujib
Science and Technology University in Jamalpur, further enhancing our academic knowledge and
practical understanding.
During this study tour, our focus was on the intriguing subject of "Aquafarm Design and
Construction." As aspiring fisheries professionals, we had the remarkable opportunity to explore
the intricacies of various aqua-farm systems, gain insights into their design principles, and delve
into the fascinating processes involved in their construction. This hands-on experience enriched
our theoretical knowledge, providing us with valuable real-world perspectives.
Objectives
The study tour to Zohurul Fish Farm aimed to provide an objective understanding of aqua-farm
systems, their design process, and the construction process, considering the local and global
context of small-scale, commercial, and industrial aquaculture production for food security.
Discussion
In designing and constructing a pond in Bangladesh, there are several factors to consider, such as
the purpose of the pond, its location, the size, and shape of the pond, and the materials and

4. 3 | P a g e
techniques used for construction. Here are some general guidelines for pond design and
construction:
a) Purpose: Determine the primary purpose of the pond, such as irrigation, fish farming, or
domestic use.
b) Location: Choose a suitable location for the pond that is close to a water source and has
good drainage.
c) Size and shape: Decide on the size and shape of the pond based on its intended use and
the available space. Rectangular ponds are commonly used in Bangladesh.
d) Excavation: Excavate the pond area to the desired depth and shape. Use the excavated soil
to construct an embankment around the pond to prevent water seepage.
e) Lining: Line the pond with a layer of clay or bentonite to prevent water leakage.
f) Inlet and outlet: Provide an inlet for filling the pond with water and an outlet for draining
excess water.
g) Water supply: Ensure a reliable water supply for the pond, such as a nearby river or well.
h) Aeration: Consider installing aeration systems to promote oxygen exchange and prevent
algae growth.
i) Fish stocking: If using the pond for fish farming, stock the pond with appropriate fish
species and ensure proper feeding and maintenance.
j) Maintenance: Regularly maintain the pond by removing debris, controlling weeds and
algae growth, and monitoring water quality.
It is important to consult with local experts or authorities for specific regulations and guidelines
for pond construction in Bangladesh.
Renu Procedure:
A fish begins to spawn from the age of 3 years. Hormones are pushed every March for spawning.
Three ponds were injected one day per week before 21 days of injection. Fishing starts at 12 PM
for conditioning and dosing starts at 10 PM. Half the male dose is given to the female (half the cc
dose is given to the male if 1 cc is given to the female).

5. 4 | P a g e
➢ Spawning Age: The fish begins to spawn from the age of 3 years. This means that once
the fish reaches the age of 3, it becomes sexually mature and capable of reproducing.
➢ Hormone Injections: To induce spawning, hormones are administered to the fish.
According to information hormone injections occur every March.
➢ Injection Schedule: Three ponds are being injected, one day per week, before 21 days of
injection. This implies that the hormone injections are administered once a week for three
consecutive weeks, starting 21 days before the expected spawning period.
➢ Fishing Conditioning: Fishing starts at 12 PM for conditioning. This suggests that before
the hormone injections, the fish undergo a conditioning period that prepares them for
spawning. The purpose of this conditioning phase may vary depending on the specific fish
species and breeding program.
➢ Dosing Timing: The dosing process begins at 10 PM. This likely refers to the
administration of the hormones to the fish. The reason for conducting the dosing at this
particular time is not specified.
➢ Male and Female Doses: According to Mr. Parvej’s information, the male fish receive
half the dose and the female fish receive the full dose. Similarly, if 1 cc is given to the
female, the male receives half a cc. This dosage practice suggests a specific ratio or
proportionality between the male and female fish when it comes to hormone
administration.
➢ Dose Names: Mr. Parvej mentioned "Ovohom," "Ovopin," and "Yon" as the names of
the hormone doses.
Ovulation Timing:
Ovulation, the release of eggs from the female fish, typically occurs between three hours and
seven to eight hours after the hormone injection. This indicates the approximate timeframe within
which the fish's reproductive process is initiated after the administration of hormones.

Monosex Tilapia:
• Tilapia is a type of fish that is originally from the Philippines and Thailand. In Tilapia
breeding, the current generation is the 34th, and each generation is growing 20 to 25% larger
than the previous one. Hormonal treatment is a key aspect of tilapia breeding.
• The breeding process involves collecting eggs from the nests every week and hatching them
indoors using a special rotating system. The fish are given hormone treatments for seven days
indoors. There is also a separate treatment for mature fish. Showers are used to maintain
oxygen levels in the water.
• After the initial hormone treatment indoors, there is a 21-day "Asthma Hormone
Treatment," although it's unclear what this specifically means. The hormones used are
described as carbohydrate medicine, but we don't have details about their specific types or
composition.
• Changing the enclosure or net (called Hapa) every seven days is recommended to help the
fish grow better. The Tilapia are fed with hormones from the Argent Company, which cost
8,000 takas for 10 ml. The hormones are mixed with food, consisting of two mL of hormone
and ethanol. The fish are fed increasing amounts of this hormone mixture over four weeks: 50
grams in the first week, 75 grams in the second week, 100 grams in the third week, and 150
grams in the fourth week.

7. 6 | P a g e
• A single 10 ml dose of the hormone can be used for approximately 800,000 fish. Tilapia carry
eggs in their mouths, and there are three different types of egg quality. However, specific
details about these types are not provided. Tilapia are generally less prone to diseases
compared to other fish species. After hatching, there may be instances of rot in the larvae.
Timsen, given at a rate of one gram per 10 tons of water, is used to treat tail rot.

Overview:
The study tour to Zohurul Fish Farm was a testament to our university’s commitment to providing
us with holistic and practical education. It not only bridged the gap between theory and practice
but also instilled in us a passion for exploring innovative approaches and shaping the future of the
fishery industry through sustainable aqua-farm systems.

Conclusion:
The study tour of Zohurul Fish Farm made a connection between our academic knowledge and
the practical implementation of this knowledge. Though the study tour was short, it was a
significant knowledge-based tour. We have come in contact with fish processors in the real world,
which will make us more professional in this sector in the future.
