The Fisheries Statistics Division of the Philippine Statistics Authority (PSA) maintained the quarterly data series since 2002. Prior to 2002, only annual municipal fisheries data were available by province by region and by species. These data were published in yearly publication of Fisheries Statistics of the Philippines. Data collection for fisheries was originally under the Bureau of Fisheries and Aquatic Resources (BFAR) until the creation of the BAS in 1987. Pilot survey of municipal fisheries was conducted in 1976. Sampling over space and time was done. Monthly survey was conducted in sample landing centers in selected days of the month in every coastal province in the Philippines. Statistical Researchers (SRs) were hired to observe actual unloading of fish in sample fish landing centers. Annual municipal fisheries data were available by region and by province. Catch by species, by fishing ground and by fishing gear were also generated from the survey. These data were published annually in Fisheries Statistics of the Philippines until 1987. When the mandate of collecting fisheries statistics was transferred from BFAR to BAS (now PSA), actual field data collection was temporarily suspended for administrative reasons. Alternative methods of estimation were used to produce fisheries statistics in the absence of surveys. Estimation of fish production was done at national level with some indicators coming from Operations Centers. Regional and provincial outputs were distributed with 1985 as the baseline data. Improvements of survey design were developed through the years, until the quarterly survey of landing centers was adopted in 2002. Due to budgetary constraints, this quarterly survey of traditional fish landing centers was deemed to be the most appropriate design to get the desired information on volume and value of fish production. Since then, the BAS started to generate fish production by quarter, by province and by region. Fishing boat Municipal fishing Municipal waters Value of fishery production Volume of fisheries production Landing Center Fishing Ground Economic/sectoral/fisheries Municipal fisheries is one of the three (3) sectors of fisheries, the others being Commercial fisheries and Aquaculture. Municipal fisheries cover fishing in marine and inland waters. The Quarterly Municipal Fisheries Survey (Traditional Landing Centers) is a survey on volume and price of fish unloaded at sample municipal fish landing centers by fishing boats with gross tonnage of three (3) tons and less. Data is collected through personal interview of at least five (5) key informants knowledgeable on the fishing activities at the sample fish landing center. Key informants may be a fisherman, fishing boat operator, fish trader, fish broker, or barangay officials. Monthly volume and price of fish unloaded at the landing centers are gathered on the last week of the last month of the reference quarter. Data on marine municipal fisheries are collected in fish landing centers where fishermen unload and trade their catch. There are two (2) types of municipal fish landing centers, namely: the traditional and those managed by Philippine Fish Development Authority (PFDA) and Local Government Units (LGUs). The two types of survey conducted in traditional municipal fish landing centers are the monthly or probability survey and the quarterly or non-probability survey. For monthly surveys, Statistical Researchers (SRs) are hired to do the actual interview of fishermen unloading at the sample fish landing centers. In the absence of adequate funds intended for the payment of wages for SRs, quarterly surveys are conducted by the regular staff in the Provincial Statistics Offices (PSOs). The general objective of the survey is to generate information on the quarterly volume and value of fish unloading by species at the provincial, regional and national levels. Philippines National Coverage Entreprises All traditional municipal fish landing centers Sample survey data [ssd] The scope of the Quarterly Municipal Fisheries Survey in traditional fish landing centers include: - Reference quarter for the current year - General Information (region and province) - Landing centre (complete name and stratum or classification of the sample fish landing center) - Complete name and type of key informant - Monthly volume of fish unloaded by species during the reference quarter - Monthly price per kilogram of species unloaded in the landing center during the reference quarter - Reasons for change in volume of unloading The list of all municipal fish landing centers in the country serves as the sampling frame for the Quarterly Municipal Fisheries Survey (QMFS) of traditional fish landing centers. Stratified sampling by province is employed with volume of unloading per day as stratification variable. The landing center serves as the primary sampling unit. The landing centers are grouped into the following strata: Stratum 1 - consists of the top producing fish landing centers Stratum 2 - consists of the major producing fish landing centers Stratum 3 - consists of all other landing centers Simple random sampling is used in drawing the sample landing centers from the stratum. Replacement of sample landing center is allowed for landing centers with unstable peace and order situation and for hard or difficult to reach areas. A total of 840 sample landing centers were covered nationwide. No deviation from the survey design. Face-to-face paper [f2f] A factor derived from the number of total fish landing centers over the sample fish landing centers by stratum is used to estimate the total volume of fish landed by municipal fishing boats in the province. This factor varies from one province to another. Manual editing of questionnaires at the provincial level is needed before the electronic data processing of survey data. Steps in data editing include the following: a) Completeness of data items in the questionnaires b) Correctness of unit of measurement used c) Coding and encoding d) Expansion factors used Before the results are summarized, another series of consistency and completeness check was made during electronic data processing. To facilitate data processing, summarization and generation of output tables for data review, a Fisheries Data Generation System in MS Excel format is prepared. For Municipal fisheries sub-sector, Municipal Data Generation (MunDatagen) system is used to generate provincial and regional municipal fisheries production and value estimates by species. Data collected in QMFS Form 1 are encoded in landing center worksheets of MunDatagen. These landing center worksheets serve as inputs to Provincial Data Generation Worksheet. The provincial worksheets are finally compiled and summarized at the regional worksheets. Response rate for quarterly municipal fisheries survey is 100%. Since quarterly survey of municipal fish catch was done through interviews of key informants, validation of responses is needed. Additional information was gathered from interviews of people from government and non-government agencies and offices and other stakeholders in fisheries. Use of auxiliary information was also one way of validating data generated by the survey. Examples of these were the programs for the improvement of catch of fishermen by the Bureau of Fisheries and Aquatic Resources, record of weather disturbances and provinces affected, existing fishery laws, report or study on status of fishing grounds, etc. Comparing current estimates with the time series data was also one way of appraising survey results.
