This presentation summarizes the internship of Noorlela Bt Md Yassin at the Borneo Marine Research Institute Fish Hatchery. The hatchery is divided into several areas for broodstock management, juvenile rearing, and culture of different species. It utilizes a recirculating aquaculture system and focuses on species like groupers and seabass. Routine activities include cleaning, feeding, and treatments. Artificial production involves selecting broodstock, hormone injections, stripping eggs and sperm, and fertilization. The internship provided hands-on experience in hatchery management and aquaculture.

- 41. Conclusion • Hands on experience in hatchery management in aquaculture industry – Managing fish culture – Handling fish – Learn about fish behaviour – Artificial production
Editor's Notes
- Assalamualaikum and good afternoon everyone my name is noorlela and I will proceed this presentation on..
- BMRI’s fish hatchery the ( ) and I will present further on one of the area that have been assigned to us which is the B area ( ) and I will end it with conclusion
- This the fish hatchery
- Located near the BMRI building in UMS
- Just a brief history. It is established in 2002 And designed by
- Generally what is fish hatchery? Place for artificial breeding, hatching and rearing through the early life of finfishes or shellfish for commercial purposes. BMRI’s Fish Hatchery: Foundation of aquaculture program It provide practical site for the aquaculture students where they can obtain the necessary skills in the aquaculture industry. It only focus on fin fishes.
- The students are able to see and experience all the management steps that are carried out in the hatchery including: 1. Broodstock management 2. Spawning- process of releasing the eggs or sperm Natural spawning- is when the fish releases the eggs or sperm on their own. Artificial spawning- Hormone injection and let them releases their eggs or sperm on their own. Fully artificial fertilization- Hormone injection and stripping eggs or sperm 3. Fertilization 4. Larval and juvenile rearing 5. Sales and distribution
- The fish hatchery is run by… (nama sensei) along with
- Moving on to the areas in fish hatchery
- The fish hatchery is divided into different areas, First is the…. A Area- Culture fresh water spp B Area- Culture Marine spp L Area- for egg, larval and juvenile developmental area F Area- culture fresh water spp
- A Area- Culture fresh water spp B Area- Culture Marine spp L Area- for egg, larval and juvenile developmental area F Area- culture fresh water spp

- A Area- Culture fresh water spp B Area- Culture Marine spp L Area- for egg, larval and juvenile developmental area The CD area which include….
- A Area- Culture fresh water spp B Area- Culture Marine spp L Area- for egg, larval and juvenile developmental area F Area- culture fresh water spp CD area consist of rotifer culture, F. water & aquaponic
- A Area- Culture fresh water spp B Area- Culture Marine spp L Area- for egg, larval and juvenile developmental area F Area- culture fresh water spp CD area consist of rotifer culture, F. water & aquaponic
- I will discuss further on what we have done in the B Area. And the rest of the areas will be discussed by my two other colleagues.
- For introduction B area: B Area is the place for broodstock management and juvenile rearing of marine fish species. It consist 6 tanks (they called it the “B Tank”) Each with 4 meter wide and 3 meter deep holding 150 tonnes capacity.
- It applied the Recirculation Aquaculture system which consist of culture tanks and filter tanks. The filter tanks have layers of coral rocks up to 1.5m depth
- What is Ras? Explain on how it works: It operates by filtering water from the culture tanks using the filter tank so it can be reused within the tank. And why are they using this, is because This system reduces the amount of water and space required. The water from the culture tank will be transferred to the filter tanks. Using the “airlift” mechanisms they insert aeration inlet (here) thus the air helps to push the water up to the filter tanks. Then the filtered water will transferred back to the culture tank using the same mechanisms.
- Using RAS the water may be treated by two processes First is mechanical filtration by the trash net where it collects solid wastes such as faecal matter, uneaten feeds, and etc Indicate presence of eggs
- Second, biological filtration by coral rocks which remove dissolved toxic wastes such as ammonia.
- The major species that they have in B Area
- the hatchery has successfully produced The first-in-the-world ‘TGGG hybrid’ The hybrids have not been released in the wild. They are suitable for commercial-scale production if effective controls are in place to prevent their release into the natural environment.
- These are the Few example of hybrid remaining in UMS H.
- We also doing routine work such as.
- Why? Control diet Prevent obese To reduce diseases (trash fish carrier) Trash fish (Ikan baja) Low value fish (dulu) Senang di dapati
- And their diet are consist of Refer again on the kintaro feed
- Maintenance work such as making fish cages and houses and also I helped in sewing new trash net.
- In addition to routine work occasionally we also involve in fish treatment
- Such as….. Each tanks, the fish are monitored. If the fish are badly infected with parasite It will show Some of the symptoms such as Skin lesion Stress (behavior & colour) they will undergo fresh water treatment, where we will put the fish in fresh water tanks for few minutes. Once exposed to fresh water the high possibility parasite detach themselves or die. Note on the fish (high priority)
- The fish might have some excess air in its body cavity. It needs to be remove as it might affect the fish’s swimming pattern So we remove it by puncturing the affected part using needle.
- For some of the critically ill fish. Who have lose their appetite to eat or to weak to eat themselves. We will apply enforce feeding where we blend the fish pallet together with cod liver oil. T hen we will use modified syringe and inject the food directly into the fish’s stomach. This is to ensure that the sick fish is still well nourished.
- We are also involve in the artificial production in fish hatchery Where the process starts with the Brood stock selection soft distended abdomen for both Reddish genital papillae for female pointed
- Once the brood stock is chosen they will under go hormone treatment via injection
- After hormone treatment the fish are monitored to see the maturation of the eggs or sperm. Once matured they will under go stripping process They will press the fish abdomen to release the eggs and sperm and collect it.
- Once collected we will fertilized them by mixing
- As conclusion, working in fish hatchery give us the hands … Despite the hard work and challenging working environment, it was an enjoyable and educational experience for us. I would like to say thank you to the hatchery family for your guidance and sharing your knowledge to us.
