• Brief history:
– Established in 2002
–Designed by Prof. Dr. Shigeharu Senoo
• What?
Place for artificial breeding, hatching and rearing through the early life of finfishes or shell fish for commercial purposes.
• BMRI’s Fish Hatchery:
Foundation of aquaculture program
• Hatchery Management steps:
– Broodstock management.
– Spawning
– Fertilization
– Larval and juvenile rearing
– Sales and distribution

Introduction• Broodstock management and juvenile rearing
of marine fish species.
• Consist of 6 tanks.
• Recirculating Aquaculture System (RAS).

• Water treatment by two processes:
– Biological filtration
• By coral rocks
Species
Epinephelus lanceolatus (Giant grouper)
Epinephelus fuscoguttatus (Tiger grouper)
Epinephelus coioides (Orange spotted grouper)
Lates calcarifer (Seabass)
Cheilinus Undulatus (Napoleon Wrasse)
Hybrid Species
• The first-in-the-world TGGG Hybrid
– cross between Tiger grouper (E. fuscoguttatus) and
Giant grouper (E. lanceolatus)
• Suitable for commercial-scale production
• Not been released in the wild.
• Effective controls must be done to prevent their
release into the natural environment.
Tiger grouper x Giant grouper (TGGG hybrid)
Orang spotted grouper x Giant grouper(OGGG hybrid)
Mouse grouper x Tiger grouper (MGTG hybrid)
Routine• Cleaning trash net.
Routine
• Feeding:
– 3 times a week
• Diet:
– Trash Fish
– Fish Pellet
– Squid
– UMS formulated feed (Kintaro)
Routine
• Maintenance
Treatments
• Parasite treatment:
• Fish are badly infected by parasite.
• They will under go fresh water treatment for few minutes.
• Buoyancy issue treatment:
• Fish found floating upside down on surface of water.
• Remove the excess air.
• Enforced feeding treatment:
• Fish are critically ill and lose their appetite to eat or to weak to eat themselves
• Use modified syringe and inject food directly into the fish’s stomach
Artificial production
• Broodstock Selection:
– Selection of male and female adult fish.
– Criteria that they looking for:
• Soft distended abdomen for both male and female
• Reddish genital papillae for female
• Pointy genital papillae for male
• Hormone treatment via injection:
– Injected to the female fish.
– HCG (human chorionic gonadotropin hormone)
– Injected to either Dorsal or pectoral fins
• Dose 500iU/Kg
– To enhance the egg maturation.
• Stripping process:
– Collection of egg and sperm (artificial spawning)
Egg collection Sperm collection
• Fertilization
– Mixing the collected eggs and sperms to allow fertilization.
– Once fertilized the eggs will be transferred to L area to monitor the development.
Conclusion
• Hands on experience in hatchery management in aquaculture industry
– Managing fish culture
– Handling fish
– Learn about fish behaviour
– Artificial production
