Conference paper
Antibiotic uptake of the giant freshwater prawn Macrobrachium rosebergii by the osmotic infiltration technique.
- In JL Maclean, LV Dizon & LV Hosillos (Eds.), The First Asian Fisheries Forum. Proceedings of the First Asian Fisheries Forum, 26-31 May 1986, Manila, Philippines, 1986 - Asian Fisheries SocietyErythromycin and oxytetracycline uptake by the giant freshwater prawn, Macrobrachium rosenbergii , was evaluated by the two-step osmotic infiltration technique. Test prawns were immersed in 7.5% NaCl conditioning (hyperosmotic) solution for 30 min. then transferred to a freshwater (hypo-osmotic) solution containing 10 mu g/ml of antibiotic. Antibiotic uptake was determined in test and control prawns at 5, 10, 20 and 40 min. Maximum concentration of erythromycin was observed in test prawns 10 min. after exposure, whereas the same concentration was not achieved in control prawns until 40 min. Oxytetracycline uptake was similar in treated and control prawns in that maximum tissue levels were observed after 40 min. in both cases. The uptake of erythromycin was significantly greater in prawns treated for 10 min. than in prawns treated for 5, 20 and 40 min. Osmotic infiltration did not significantly enhance oxytetracycline uptake at all time intervals tested. -

Philippine National Standard: Organic aquaculture
- 2016 - Bureau of Agriculture and Fisheries StandardsThe Philippine National Standard (PNS) for Organic Aquaculture (PNS/BAFS 112:2016) was originally prepared and adopted in 2012. Organic aquaculture encourages polyculture production system, promotes the use of indigenous/endemic species under the extensive and semi-intensive culture systems, reduces/minimizes inputs of artificial ingredients, prohibits the use of genetically modified organisms (GMOs), and considers ecological conditions necessary for sustainable aquaculture production. The PNS for Organic Aquaculture was revised by the Technical Working Group (TWG) organized by the Bureau of Agriculture and Fisheries Standards (BAFS) through a Department of Agriculture (DA) Special Order No.476, Series of 2015. The TWG is composed of members representing the Bureau of Fisheries and Aquatic Resources (BFAR), Organic Certification Center of the Philippines (OCCP), Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC-AQD), Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD) and Central Luzon State University (CLSU). This PNS was presented and reviewed during the consultative meetings with the concerned stakeholders in Region I (Pangasinan) and Region XI (Davao City). Comments gathered during the consultations were carefully evaluated by the TWG and included accordingly in the final version of this standard. Drawn from the general principles of the Philippine National Standard on Organic Agriculture, this PNS on Organic Aquaculture attempts to cover the aquaculture production and postharvest operations in order to ensure the integrity of organic products. The requirements for the inclusion of Substances and Criteria for the development of the list of substances shall follow the Philippine National Standards for Organic Aquaculture and the Guidelines for the Production, Processing, Labelling and Marketing of Organically Produced Foods (GL 32-1999). The revision of this PNS was undertaken in order to achieve equivalence with the existing international standards and its future amendment, and takes into consideration the new developments and inclusion of the identified potential species for organic aquaculture. Thus, this PNS identifies minimum requirements on documentation, conversion to organic aquaculture, parallel production, selection of site, interaction with surrounding ecosystem, organic fertilization, aquatic plants, aquatic animal sources/origin, breeding and hatchery management, aquatic animal nutrition and feeding, aquatic animal health and welfare, harvesting, post-harvest handling, transport and processing, storage, and social aspects. -

Stock enhancement activities in the Union of Myanmar
- In JH Primavera, ET Quinitio & MR Eguia (Eds.), Proceedings of the Regional Technical Consultation on Stock Enhancement for Threatened Species of International Concern, Iloilo City, Philippines, 13-15 July 2005, 2006 - Aquaculture Department, Southeast Asian Fisheries Development CenterPresented in the paper are the stock enhancement programs of the Union of Myanmar which is being implemented by the Department of Fisheries. The State’s vision is to assist the national economy by promoting livelihood programs for rural people through the development of the fisheries sector. To achieve such goal, one of the major activities is to undertake a stock enhancement program which has been implemented since 1983. The DOF subsidizes the annual seeding of freshwater fish and prawns into natural waters. Species used in seeding include common carp (Cyprinus carpio), tilapia (Oreochromis), rohu (Labeo rohita), catla (Catla catla), and featherbacks fish (Notopteridae), freshwater prawn Macrobrachium and tiger shrimp Penaeus monodon. Activities include annual stocking of seeds in the Ayeyarwaddy River and its tributaries, lakes, reservoirs, dams and other bodies of water.
