• 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).

• By Trash net

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
