NADA Bureau of Fisheries and Aquatic Resources Chief, Fisheries Statistics Division Agricultural Survey [ag/oth] Fishpond was the only known type of aquafarm during the 50s and the 60s. Estimates were combined production from brackishwater and freshwater fishponds but mostly from the former. Data on area were taken from Fishpond Lease Agreement (FLA) issued by the BFAR for government-leased fishponds, while data on area for privately-owned fishponds were obtained from survey made some years ago. Annual production was estimated by multiplying the area of fishponds by the average productivity of fishponds by province. Estimates of the average productivity of fishponds per hectare per year by province were derived by the Fisheries Commission without the conduct of a survey. There was no available data on area for brackishwater and freshwater fishponds separately. To determine the average productivity of fishponds by province and to replace the unreliable factors used in the estimation, 200 sample operators were interviewed. In 1991, listing of all brackishwater fishpond operators was done nationwide under the Fishery Sector Program (FSP). Meanwhile, listing of all other types of aquafarms was accomplished in 1992. Semestral surveys of aquafarms in 56 provinces started in 1992. When the project ended in 1995, production indicators were taken from surveys of aquafarms from 14 to 27 major producing provinces. From early 2000 to present, aquaculture production growth was estimated based on quarterly surveys of top five (5) operators in top five (5) municipalities in a province for each type of aquafarm. Aquaculture production levels are benchmarked on data collected through the Aquaculture Production Survey (AqPS). Prior to this survey round, the last conduct of AqPS was the 4th quarter 2008 round. A slight modification in the sampling design was employed. For this survey round, sample aquafarms were selected only from the municipalities with at least 80% cumulative share to provincial area. This was done to simplify field operations and ensure that sample aquafarms from these municipalities were more or less productive. v1.0: edited at BAS Central Office, not anonymized Food (production, crisis) RATIONALE In carrying out its responsibility of generating statistics on volume and value of aquaculture production, the Fisheries Statistics Division (FSD) of the Bureau of Agricultural Statistics (BAS) conducts probability and non-probability surveys. The Quarterly Aquaculture Surveys (QAqS) is the non-probability survey conducted on a regular basis. The survey design involves computing for the average percent change from the same quarter last year reported by the sample respondents and then applying the same to the provincial level same quarter last year estimate in order to derive the estimate for the current quarter. The samples are taken from 5 X 5 sampling design, i.e., five (5) sample operators from top five (5) producing municipalities. On the other hand, Aquaculture Production Survey (AqPS) generates the production estimates based on one-stage stratified sampling design. Unfortunately, this probability survey is not financially sustainable on a quarterly basis. It should be noted that estimates from the probability survey are intended as baseline data for computing the percent changes derived from non-probability survey. Although quarterly estimates are subjected to a series of data review and analysis before final estimates are released, it is imperative to determine the levels of production estimates through a periodic probability survey. OBJECTIVES Primarily, the Aquaculture Production Survey (AqPS) aims to generate statistics on volume and value of aquaculture production by province. Specifically, it aims to gather information on: a. Volume and value of production by species cultured, by aquafarm type and by environment, b. area harvested; and c. management and culture system of the aquafarm. Philippines National The domain of the study is province. Aquafarm is the unit of analysis. All aquafarm types. Sample survey data [ssd] The survey form gathers information on the following: AQUAFARM INFORMATION: Aquafarm area, aquafarm type, environment, management system and culture system PRODUCTION INFORMATION: Species, quantity stocked, area harvested, production and price. Bureau of Agricultural Statistics The AqPS adopts one-stage stratified sampling design. By aquafarm type, all operators from municipalities with at least 80% cumulative share to total provincial aquafarm area are stratified into three (3) strata using area as the stratification variable. The boundary between strata is determined by the distribution of data. If the number of aquafarms in a stratum is less than or equal to fifteen (15), all aquafarms shall be taken as sample. Sample aquafarms shall be selected through systematic random sampling procedure. In 2009, AqPS was conducted in 40 provinces contributing to at least 90% of the total production of each aquafarm type. Face-to-face [f2f] There were two (2) AqPS survey forms that were used depending on the type of aquafarm. AqPS Form 1 - for all aquafarm type except Oyster, Mussel and Seaweed AqPS Form 2 - for Oyster, Mussel and Seaweed. The datasets for both forms were the same except for the following: In Block II, management system was not applicable for Form 2. There were different culture systems. In Block III, quantity stocked was not applicable for Form 2. Seaweed production information was by variety. The Contractual Data Collectors (CDCs) were hired to conduct the interview of the owner/operator and/or caretaker of the sample aquafarms using the survey forms. Prior to data collection the CDCs were trained and supervised by the Provincial Agricultural Statistics Officer (PASO). They were given assigned municipalities to cover. BAS field staff were assigned to supervise the CDCs. The Provincial Agricultural Statistics Officer (PASO) provides the over-all supervision of data collection. He trains data collectors, assigns area of coverage and schedules the data collection. To ensure the smooth implementation of data collection, the PASO conducts spot checking and back checking activities. The Regional Agricultural Statistics Officer (RASO) may also provide another level of supervision. And sometimes, Central Office personnel may be available to provide support and control of the said activities. Aquafarm weights were computed as the quotient of total number of aquafarms and number of sample aquafarms in the stratum. Initially, the survey returns are manually edited to ensure completeness and accuracy. During this stage, survey returns are checked for completeness from the list of samples. For each of the survey forms, entries should be complete and numeric entries are in proper unit of measurement and decimal places. After encoding, the entries are then again inspected and reviewed for completeness, accuracy and consistency with other items. Response rate is not available. Not available.

Refers to a system where stocking rate ranges from 3,000 pcs to 5,000 pcs/ha for milkfish. 1-15 pcs/sq.m. for shrimps. The cultured species depend completely on natural food propagated in the pond with or without fertilization and depends solely on tidal water exchange. 2. Semi-intensive. Refers to a system where stocking rate ranges from 16-25 pcs./sq.m. for shrimps and from 5,001 to 20,000 for milkfish and 40,000 to 80,000/ha for tilapia. This requires supplementary feeding of commercial pellets, trash fish, etc. aside from the natural food propagated in it. Water pumps are used aside from the tidal water and paddle wheels as aerators. 3. Intensive. Refers to a system where ponds are smaller about 1,000 to 5,000 sq m; stocking rate ranges from for 26-40 pcs/sq.m. shrimps from 20,001 to 50,000/ha for bangus. The high stocking could only be supported through major inputs such as formulated feeds mostly in pellet form. Water exchange is done through pumps and paddle wheels are also needed for aeration purposes.

Monoculture. Refers to the culture of single species in one compartment 2. Polyculture. Refers to the culture of two or more species in one compartment 3. Others. Refers to other culture systems not classified above. FOR OYSTER AND MUSSEL 1. Staking. A culture method where bamboo poles either whole or halved are driven into the bottom where the water is not less than 1 meter deep during the lowest tide. These are aligned and spaced at 1 to 2 feet. The bamboo poles act as collectors 2. Hanging. An off-bottom method of culture that is suitable in relatively deeper waters of at least 2.5 meters depth during the lowest tide. Empty oyster shells or coconut shells are used as collectors. The shells are hung to a meter of no. 10 galvanized iron wire having a space of about 4 inches by a loop on the wire 3. Spreading. This culture method makes use of stones, gravels, empty oyster shells, and other media as collectors. These are positioned in hard bottom areas where natural populations of oysters/mussels are known to occur 4. Others FOR SEAWEED 1. Bottom monoline. Monolines are constructed by the use of mangrove post or wooden stakes anchored/staked deep into the substrate at 10 meters apart and 32-cm. interval in rows. 2. Floating monoline. A method where a raft or longlines can be constructed in any way feasible as long as it will buoy up the line with plants, which are at least 30-cm. submerged in water. 3. Triangular. This method uses polyethylene rope #12 as cultivation line fixed five meters from the bottom through a wooden stake embedded firmly to the seabed. A rope of smaller size (#7) is used to construct a triangle 4. Others.
