These simple, easy-to-follow manuals are intended as extension education materials that can be used by extension agents, aquaculturists, researchers, academicians and students, policy makers, farmers and other interested parties. Since its inception, AQD has published several extension manuals on production of various aquaculture commodities. As other technologies are verified for commercialization, more extension manuals are planned to be published in the near future.

    Soft-shell crab production using hatchery-reared mud crab 

    EJ Tobias-Quinitio, GXS Libunao, FD Parado-Estepa & AT Calpe - 2015 - Aquaculture Department, Southeast Asian Fisheries Development Center; Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD)
    Series: Aquaculture extension manual; No. 61
    "The production of soft-shell crabs is well established in other Asian countries but its sustainability is already being threatened due to the decreasing mud crab population in the wild where the seedstocks are sourced. In the Philippines, production of soft-shell crabs has only been practiced recently due to lack of seedstock and technology. Sourcing of crablets from the natural environment is not encouraged due to dwindling populations of all sizes of mud crabs. Instead, it is recommended that crablets for soft-shell crab production come from hatcheries. The project on soft-shell mud crab production at SEAFDEC/AQD started in 2012 and was later funded by the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the Department of Science and Technology. The project is adopting the individual crab culture sytem of Thailand and Myanmar in pilot-scale and uses hatchery-reared crablets grown to 60-100 g in earthen ponds and stocked in trays. The pilotscale soft-shell production set-up is showcased at the Dumangas Brackishwater Station of SEAFDEC/AQD using crab boxes available in the country. Various sectors are interested to learn how soft-shell crabs are produced. Hence, the previous manual on Soft-shell Mud Crab Farming by Emilia T. Quinitio and May Myat Noe Lwin published in 2009 was revised to include the recent refinements using hatchery-reared crabs and locally available materials. This manual includes sections on the biology of mud crab, how to set-up the facility, management of soft-shell crab production and the cost and return analysis. We hope that various sectors will benefit from this revised manual" -- Foreword

    Development and management of milkfish broodstock 

    OS Reyes, EGT de Jesus-Ayson, BE Eullaran, VL Corre Jr. & FG Ayson - 2015 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Series: Aquaculture extension manual; No. 62
    The manual provides developed and refined techniques for collection and transport of spawned eggs and larvae, as well as larval rearing. It also describes the necessary facilities for maintaining milkfish broodstock.

    Guidelines on transporting broodstock, performing biopsy to determine sex of spawners, collecting and cleaning eggs, packing and transporting eggs to hatchery, incubating and hatching eggs, and packing and transporting of larvae are also provided in the manual.

    The importance of nutritional quality of the diet in relation to the performance of the milkfish broodstock and quality of resulting eggs and larvae is also explained in the manual.

    Broodstock feeds are enriched with vitamin C, beta-carotene, and other nutrients for better reproductive performance of broodstock and better egg and larval quality. It also offers formula to initially estimate the number of spawned eggs and determine the hatching rate.

    The manual guides stakeholders and operators who are interested in setting up breeding facilities for milkfish.

    Grow-out culture of mangrove red snapper (Lutjanus argentimaculatus Forsskal, 1775) in ponds 

    EB Coniza, MR Catacutan & PA Caballero - 2012 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Series: Aquaculture extension manual no. 53
    The mangrove red snapper is among the high-value marine fishes with great potential for export. Snapper is important to coastal fishery and ideal for aquaculture particularly in Southeast Asia. Grow-out culture of snapper are described - pond culture and culture in cages inside the ponds. In the pond culture, the whole area can be maximized and the available natural food can be utilized by snapper. In rearing snapper in cages inside the pond, fish sampling and harvesting are easily done and also in preventing of disease infection and securing of fish stocks during flooding. In both culture methods a good site would have a mangrove buffer space about 20-100 m that lies between the ponds and the source of water like river or sea. Pond soil with a good water retention property is desirable for dike construction. Water supply should be adequate year-round, free from pollutants and run-off flooding. Pond supplies, labor and technology should be available on the selected site which is also accessible to markets with peaceful locale. The pond for growing snapper should be prepared well in order to promote good growth of fish, to minimize pollution, and prevents the proliferation of pathogens. Stocking of healthy and larger uniform size juveniles will mean higher survival, faster growth and shorter culture period. Proper handling of juveniles during harvest, size-grading, counting, packing, transport, acclimation and stocking should be observed and should be done during the cooler part of the day. Recommended juveniles for grow-out is about 20-100 g average body weight (ABW) and stocking densities of 5,000/ha in ponds, and at 5 pcs/m3 or 5,000 pcs/ha when stocked in cages inside the pond. During culture, good water quality is maintained and when necessary the cleaning of net cages, repair of dike leaks and seepages, and aeration are to be considered. Snapper dietary protein is about 48-50%. The following are the factors to consider in the feeding management of snapper: total stock (pcs), survival (%), ABW (g), feed rate (% biomass), feed type, feed size, feeding frequency and time. Economic analysis based on 0.422 ha pond shows that feeds accounted for 60-67% and juveniles contribute 23-25% of the variable cost. The feed conversion ratios, return on investments, payback period and discounted benefit-cost ratios are 2.5 and 2.6; 203 and 43%; 0.46 and 1.76 yr; 1.4 and 1.2 for culture of snapper in pond and culture in cages inside the pond, respectively, are likewise acceptable.

    Fingerling production of hatchery-reared milkfish (Chanos chanos) in earthen nursery ponds 

    EB Coniza, CL Marte, RM Coloso & FL Huervana - 2010 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Series: Aquaculture extension manual no. 45
    Fingerling production of milkfish in ponds maybe operated as a commercial enterprise or a component of milkfish farming that comprises nursery, transition and rearing or grow-out phases. The fishpond nursery is used to grow milkfish fry to fingerlings 1-3 g in weight or 1-2 inches in length. The nursery pond is the smallest of the major fishpond compartment ranging from 500 to 5,000 m2, and is about 10% of the total farming area. The pond is prepared with utmost care to eliminate predators and competitors. The area should have good topography, is free from flooding and should have soil with good water retention properties for good dike construction and efficient culture management. Water supply should be adequate year-round and free from pollutants. Good pond water quality is maintained and natural food should be adequate to enhance growth and survival. With high stocking densities, supplemental feed is also provided. The three types of nurseries are based on feed sources: lablab, plankton with supplemental feeding and direct feeding. Select hatchery-reared fry (21 day old) that swim actively in schools, are uniform in size, have robust body, and are resistant to handling and transport stress. The ideal fry stocking density is 5-40 pieces/m2. Survival ranging from 50-90% can be expected after 25-45 days of rearing. Harvest, packing, transport, acclimation and stocking of the fry or fingerlings are carefully done during the cooler part of the day. Economic indicators show that fingerlings production is a profitable business. The improvement of milkfish grow-out technology from extensive or traditional to modified-extensive, semi-intensive and intensive culture in ponds, pens or in sea cages has increased demand for good quality fingerlings. Mass production of hatchery-reared fingerlings in earthen nursery ponds during peak season of fry availability can help bridge the supply gap. A steady supply of fingerlings for a whole year s operation will further increase production and ensure a sustainable supply of affordable market-sized fish.
