The hatchery technique was devised by Dr. Frolan A. Aya, a scientist of the Southeast Asian Fisheries Development Center, and granted a patent by the Intellectual Property Office of the Philippines (IPOPHIL) last Oct. 17, 2019.

An award-winning technology for algae harvesting is now available in the Philippines, boosting efforts to reduce the cost of producing fish fry in hatcheries through the use of algal paste.

SEAFDEC/AQD co-organized an “On-site Training in Using Concentrated Microalgae in Larval Rearing of Sandfish Holothuria scabra” attended by 18 trainees from various hatcheries in Eastern Visayas.

Dr. Rolando Platon returns to SEAFDEC/AQD as the DKV Memorial Lecture speaker and shares his experience in tilapia hatchery operation

APEC 2015 goes to AQD's Tigbauan Main Station on 1 October 2015

The hatchery is capable of producing up to 40,000 crab instar 1 per run.

Although the technology applies to all the three species of mud crab (Scylla serrata, S. tranquebarica, and S. olivacea) available in the Philippines, S. serrata or the giant/king crab has been the focus of culture in the hatchery/nursery and grow-out pond due to its economic viability. Procedure: Obtain healthy adult crabs 500-700 g for S. serrata and 320-500 g for S. tranquebarica and S. olivacea with orange ovaries (‘aligi’) and complete legs as source of broodstock from ponds or traders. Put crabs in an empty basin and pour seawater over them slowly.  Transfer crabs to basin containing 150 ppm formalin for 30 minutes to disinfect. Transfer crabs in tanks provided with sand substrate. Feed crabs with mussel, fish and/or marine …

Technology Description Tilapia has been dubbed the “aquatic chicken” because it grows fast, breeds in captivity easily, and the technology for its propagation and culture requires little input. Hatcheries can readily supply the seedstock that the tilapia farming industry needs. Hatcheries are of three types: concrete tanks, which give the highest production; hapa netcages in lakes, the second highest; then ponds. Technology profile: (1) Get good breeders (50-250 g) from reputable hatcheries; or, raise them from the fry stage until they mature in 3 months. For the latter, breeding trials at SEAFDEC/AQD have shown that tilapia farmers can select healthy broodstocks from within the normal or average size range distribution; this means not selecting the largest fish. (2) For concrete …

Technology Description It might be expensive to integrate broodstock with hatchery; hence, hatchery operators may opt to buy milkfish eggs from broodstock operators like SEAFDEC/AQD. This distinction between egg suppliers and fry suppliers is what make Taiwan’s milkfish industry very successful because the risks are spread among sectors of the industry. Filipino entrepreneurs are enjoined to do the same. Eggs are hatched, raised, and then sold at day 21 or older. Natural food (Chlorella, Brachionus, Artemia) are fed to the larvae, enriching the rotifer and Artemia in particular with highly unsaturated fatty acids (HUFA) and Vitamin C. The SEAFDEC/AQD-formulated larval feed may be given in combination with natural food from day 3-5 until harvest. Water change, cleaning tanks, frequent monitoring …

Technology Description Brief description: Seabass can easily be spawned using a hormone and its larvae reared in the hatchery with 90% survival. The only potential problem for the hatchery operator is that seabass are protandrous hermaphrodites, that is, they first mature as males then become females on their sixth year or when they are over 3 kg in size. Should egg production decrease as a result of having more female broodstock, the operator must cull and acquire younger or male broodstock. Wild spawners may be used, or breeders raised in cages,tanks or ponds. Seabass are injected with LHRHa, and left to spawn for 2-3 consecutive days. The larvae that hatched from the eggs are fed mostly live food, Brachionus and …

Technology Description Brief description: Hatcheries are indispensable to grow-out operators especially when seedstock supply from the wild is not assured. For tiger shrimp, the technology can be relatively low-cost “backyard type” very popular among aquaculturists in the 1980s, or medium to large scale With fewer shrimp hatcheries continuing operations up to the present, the market potential is big. (Marketing is one of the problems of shrimp hatcheries. Since fewer ponds are stocked with shrimp due to disease threats/occurrence, demand for shrimp fry has also decreased). To put-up a hatchery, an entrepreneur needs to decide on target production. For every million of postlarvae (day 15-20), a total tank volume of 80-100 tons is required. This is based on these assumptions: (1) …

Technology description Although the technology applies to all three species of mud crab (Scylla serrata, S. tranquebarica, S. olivacea), S. serrata or giant/king crab has been the focus of culture due to its economic viability. Healthy mature crabs with complete limbs are chosen as breeders. The crabs are maintained in the tank until they spawn (release of eggs). After hatching of eggs, care is taken to raise the zoea to the megalopa stage in the hatchery. Feed used are Brachionus and Artemia. Water replacement may be from 30 to 80% every 5 days. Megalopae are then transferred to nursery tanks or net cages before they can be stocked in ponds or pens, and are fed mollusks or fish. Hatchery and …

Why MILKFISH? Hatchery technology for large-scale seed production is already established Easy to culture and can be grown in a wide range of environments Innovations in culture practices based on research data and farmer’s experiences have been adopted by industry practitioners An important food commodity in Southeast Asia How to culture MILKFISH? Broodstock management Milkfish takes about 3-5 years to attain sexual maturity and spawns under marine conditions. Milkfish can be grown to broodstock size (about 3-5 kg) in earthen ponds, in marine net cages, or in tanks For a start, about 100 juveniles can be stocked in a 1000 m2 pond, or 10 m diameter cage, or 200-ton tank. Growing juvenile milkfish to broodstock size for 3-4 years in brackishwater …

Why tilapia hatchery/culture? Tilapia, also known as “aquatic chicken,” grows fast and easily breeds in captivity Technology for its propagation and culture requires little input Hatcheries can readily supply the seedstock the industry needs Tilapia has become an effective biocontrol agent for luminous bacteria Generally occupies a smaller area than other culture species
