Series Information
The quarterly volume and value of commercial fisheries production by species by province are the data generated by the survey. The Fisheries Statistics Division of the Philippine Statistics Authority (PSA) maintained the quarterly data series since 2002. Prior to 2002, only annual commercial 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 commercial 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. Contractual Data Collectors (CDCs) were hired to observe actual unloadings of fish in sample fish landing centers. Annual commercial 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 Philipines 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 commerciall 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, and subsequently PSA, started to generate fish production by quarter, by province and by region.

Abstract
Commercial fisheries is one of the three (3) sectors of fisheries, the others being Municipal fisheries and Aquaculture. The Quarterly Commercial Fisheries Survey is a survey on volume and price of fish unloaded at sample commercial fish landing centers by fishing boats with gross tonnage of more than three (3) tons.
Data on commercial fisheries are collected in fish landing centers where fishermen unload and trade their catch. There are different types of fish landing centers, namely: the traditional, private landing centers and those managed by Philippine Fish Development Authority (PFDA) and Local Government Units (LGUs).
For the traditonal landing center, data are collected through personal interview of at least five (5) key informants knowledgeable on the fishing activites 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. Statistical Researchers (SRs) are hired to conduct the actual interview of fishermen unloading at the sample landing centers.
Admistrative data from LGUs, privately-managed, and PFDA landing centers are collected by regular staff or SRs during the reference quarter.
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.

Sampling
Sampling Procedure
The list of all commercial fish landing centers in the country serves as the sampling frame for the Quarterly Commercial Fisheries Survey (QCFS) of traditional fish landing centers. Stratified sampling by province was employed with volume of unloading per day as stratification variable. The landing center served as the primary sampling unit. The landing centers were 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 was used in drawing the sample landing centers from the stratum. Replacement of sample landing center was allowed for landing centers with unstable peace and order situation and for hard or difficult to reach areas. A total of 188 sample landing centers were covered distributed in 58 provinces.
All private, PFDA-managed fish ports and LGU-managed landing centers were completely covered (complete enumeration).

Response Rate
Response rate for quarterly commercial fisheries survey is 100%.
Weighting
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 commercial fishing boats in the province. This factor varies from one province to another.
