Feed mill: Products and services
Get PDFThe SEAFDEC/AQD Feed Mill, previously known as Feed Production Laboratory, was established in 1991 as a service unit of the Feed Development Section (now Nutrition and Feed Development Section) funded by the Government of Japan. It produced feeds to serve the Department’s laboratory and pond research studies, maintenance and culture of experimental animals, verification studies in collaboration with fish farmers, and large-scale production of SEAFDEC/AQD-formulated feeds for mariculture.
In 2019, the facility received a US$60,000 upgrade, which increased its daily production capacity from 0.5 MT to 2.6 MT per day. It can yield about 300 kilograms of feeds per hour. It currently produces diets for abalone, grouper, mangrove crab, milkfish, pompano, sea bass, shrimp, siganid, and tilapia. The facility also accepts orders from private hatcheries that need maintenance feeds for marine fish breeders and larvae, which are not commercially available
Navigating risks and uncertainties: Risk perceptions and risk management strategies in the Philippine seaweed industry
No full textThe Philippine seaweed industry is affected by multiple but interrelated risks. Farmers mainly encountered environment-related risks (e.g. disease, pest infestations) which, if unmanaged, could result to production failure. Traders and processors considered volatility of seaweed supply and poor quality of raw materials as precursors of other risks such as increased competition among local traders and processing companies. Gender differences in awareness and knowledge of risks were more prominent among seaweed farmers but not among traders and processors as roles become more homogenous up the value chain. Poor governance resulted in the adoption of informal and market-driven strategies to prevent or minimise losses. However, this restricted farmers to participating in higher-income trading and processing activities and contributed to increased market inefficiency. The lack of government support has also curtailed the capacity of traders and processors to engage in product development and diversification. Gender and community experiences influence and shape people’s understanding of their situations and environment including their coping and adaptive strategies in sustaining livelihoods amidst recurring risk events. Embedding informal structures and the differential needs of the stakeholders in the national institutional framework is therefore essential for the promotion of resilient and sustainable seaweed industry.This study forms part of a larger study under the GlobalSeaweedSTAR – Safeguarding the future of seaweed aquaculture in developing countries programme which is being funded by the UK Research and Innovation – Global Challenges Research Fund, United Kingdom (Grant Ref: BB/P027806/1)
Promotion of resource enhancement of seahorse in an island community in Negros Occidental, Central Philippines
Get PDFTo promote the protection and sustainability of seahorses for their conservation, efforts have been done through stock enhancement by releasing captive-bred seahorses. However, preparatory activities are necessary for the development of long-term program on seahorse stock release and enhancement by conducting baseline stock assessment, developing the appropriate release and monitoring strategies, and encouraging the involvement of concerned communities in the management of the natural seahorse resources. The Aquaculture Department of the Southeast Asian Fisheries Development Center (SEAFDEC/AQD), with support from the Government of Japan Trust Fund (GOJTF), initiated seahorse resource enhancement efforts in a remote island community in Negros Occidental in central Philippines. Baseline assessment in 2012 to 2019 of the natural stock of seahorses showed an increasing number of stocks over the years. Results of the transport trials of juvenile seahorses (5-7 cm in stretched height (SH)) suggest an optimum stocking density of 3 ind/L for transport duration up to 12 hours. Appropriate protection of the natural habitat and with no gleaning of various intertidal species, the main source of income for the coastal community, suggests a possible sustainability of the wild seahorse stock. The community involvement may be promoted by active participation thru information, education and communication (IEC) and hands-on trainings during field sampling, seed production and nursery rearing of seahorses. Relevant information derived from the activities in the island community may serve as a model for the resource enhancement of seahorses in other potential sites in the Philippines and other countries in the region.The author would like to thank Mariano Jarina, Joebert Nunez, and Francisco Bascar for their support and assistance in Molocaboc Island; Ryan Q. Tigres for technical assistance; Drs. Nerissa D. Salayo, Jon P. Altamirano, Leobert D. de la Peña, Takuro Shibuno, and Koh-Ichiro Mori for their constructive suggestions and advice; and SEAFDEC/AQD and GOJTF5 for funding support under the study code 8300-T-RD-FS0215
Aquatic animal health in Myanmar
Get PDFIn 2010, several viruses infected Penaeus monodon in the ponds of Myanmar. This includes the White Spot Syndrome Virus (WSSV) which causes the White Spot Disease (WSD). In addition, Taura Syndrome Virus (TSV) and Infectious Hypodermal and Haematopoietic Virus (IHHNV) were detected in P. monodon samples from Ayeyarwaddy Region (western part of Myanmar). In 2014, the Yellowhead Virus (YHV) was also detected in shrimp samples for export. The occurrence of these shrimp diseases has resulted to a devastation of the shrimp industry in Myanmar. Because of this, most of the shrimp farmers have shifted to extensive or traditional shrimp farming. The Aquatic Animal Health and Disease Control Section (AAHDCS) of the Department of Fisheries (DoF) is responsible for formulating action plans to control and prevent aquatic animal diseases. Thus, in order to be updated with the latest techniques on disease detection and management of emerging diseases, the AAHDCS should improve the capacity of the departmental personnel, upgrade the laboratory equipment, and improve the facilities

The brief provides policy recommendations to support sustainable growth of the national industry and ensure its long-term resilience. The synthesis also highlights the role of seaweed aquaculture in the country as a potential nature-based solution within the ‘Blue’ or Sustainable Ocean Economy agenda.This Policy Brief was produced as part of the GlobalSeaweedSTAR Programme which was funded by the UK Research and Innovation – Global Challenges Research Fund (BB/P027806/1) (2017-2021)
Farm management and biosecurity measures of Eucheumatoids: Cultivars, pest and disease, risks and risk managements
No full textThis brochure was prepared and written after four years of research of the seaweed industry of the Philippines by the GlobalSeaweedSTAR Philippine Team in a layman’s language. This provides the different stakeholders of the seaweed industry to understand and implement the mechanics of seaweed farming from the bio-ecophysiology and aquaculture point of views, to social network analysis to include risks and risk management strategies. Further, this brochure recommends policy makers to adapt in the formulation of legislatures especially on biosecurity measures to prevent or reduce the incidence of disease outbreaks, minimize risks in the production, trading and marketing levels and ultimately formulate risk management strategies. Such policies to be formulated based from science will redound to a more robust, resilient, ecologically friendly and sustainable seaweed aquaculture industry of the Philippines.Englis
Flakes versus noodles as feed for the abalone Haliotis asinina, does form matter?
No full textThis paper reports the first use of thin flakes (310–315 μm thick) formulated diets as feed for the abalone Haliotis asinina. The study compared noodles and flakes prepared using refined and unrefined diets developed earlier for H. asinina (Bautista-Teruel et al., J. Shellfish Res., 35, 2016, 633). Four treatment diets in triplicates (refined flakes, MBTr-F; refined noodles, MBTr-N; unrefined flakes, MBTur-F; and unrefined noodles, MBTur-N) were used in a feeding experiment conducted in a tank facility. After three months, abalone fed MBTr-F had significantly higher mean shell length and body weight (35.92 ± 0.36 mm, 9.24 ± 0.29 g) compared with those fed MBTr-N (34.63 ± 0.37 mm, 8.22 ± 0.28 g) and MBTur-N (34.23 ± 0.36 mm, 7.66 ± 0.26 g), but did not significantly differ with those fed MBTur-F (35.40 ± 0.30 mm, 8.57 ± 0.24 g). Likewise, abalone fed MBTr-F had significantly higher mean growth rates (5.31 ± 0.08 mm, 2.59 ± 0.06 g/month), compared with those fed MBTr-N (4.90 ± 0.19 mm, 2.26 ± 0.12 g/month) and MBTur-N (4.71 ± 0.02 mm, 2.07 ± 0.06 g/month), but did not significantly differ with those fed MBTur-F (5.11 ± 0.06 mm, 2.37 ± 0.04 g/month). Survival (96.67–98.89%) and FCR (2.2–2.5) did not significantly differ among treatment diets. Between the flaked diets, MBTur-F is the cheaper option. However, the use of this unrefined diet resulted in distinct turquoise abalone shell colour, not observed in those fed MBTr-F.The authors greatly appreciate SEAFDEC Aquaculture Department for funding the study (Study Code: FS-02-M2020T); the Abalone Hatchery staff for providing the abalone juveniles used in the study; the Feed Mill Plant staff for producing the feeds to the desired formulation and forms; Mr. Silverio Tibudan for his assistance in the conduct of the experiment; Mr. Manny Librodo for his assistance in improving the resolution of the figures; and the anonymous journal reviewers for painstakingly reviewing the manuscript
Producing young, single and meaty oyster Crassostrea iredalei (Faustino, 1932) in grow‐out culture using pouches suspended from rafts
No full textGrowth and survival of the slipper oyster Crassostrea iredalei using traditional (tires and oyster shells) and new methods (pouches and trays) suspended from floating rafts were compared. After six months of grow-out culture, mean shell length (mm SL) and body weight (g BW) of oysters were significantly highest in those reared in pouches (89.32 ± 0.41 mm SL, 87.70 ± 0.70 g BW), followed by those in trays (83.16 ± 0.31 mm SL, 87.06 ± 0.72 g BW), then those harvested from oyster shells (76.42 ± 0.88 mm SL, 67.35 ± 1.03 g BW), and lastly from tires (72.30 ± 1.21 mm SL, 55.07 ± 1.49 g BW). Growth rates both for length and weight were almost comparable between oysters reared in pouches (6.05 ± 1.28 mm mo−1, 10.98 ± 2.05 g mo−1) and trays (5.01 ± 1.46 mm mo−1, 10.77 ± 2.58 g mo−1). Although 60.7% of the oysters harvested from pouches (n = 1071) were classified as large (85–100 mm SL) and jumbo (100–120 mm SL) and only 39.5% of those from trays (n = 1048), their meat yield did not significantly differ (pouches = 22.60 ± 0.86%; trays = 24.76 ± 0.93%). Survival in pouches (95.2 ± 0.77%) and trays (93.15 ± 2.10%) was almost parallel at harvest. Growing oysters using the new methods produced single, larger, meatier oysters of almost the same size at a shorter culture duration.The Project Team greatly appreciates the Philippine Council for Agriculture, Aquatic, and Natural Resources Research and Development of the Department of Science and Technology (DOST-PCAARRD: Project Code 6286-TRD- DOST- O4) for this three-year project collaboration; Dr. Mari-Ann M.

Touch-sensitive bristles on the carapace of the mud crab Scylla paramamosain may be receptors for courtship signals
No full textBristle patches on the carapace behind the eyes were found for the first time in both males and females of the four species of mud crab Scylla spp. Electrocardiography revealed that the bristle patches of Scylla paramamosain were sensitive to touch (with a glass capillary) but not to chemical stimulation (with sugarcane juice). To elucidate the function of these touch signals, the courtship behaviour of S. paramamosain was video-recorded in a broodstock tank. A male approached a female, extended a walking leg over her carapace, touched her bristle patches with a dactyl, mounted her, and probed the bristle patches further with the third maxillipeds. Touch stimulus may be a signal for courtship in Scylla and one of the chain stimuli for the completion of mating behaviour.This study was partially funded by Universiti Malaysia Sabah grant SDK0028-2018
