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 two (4) 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 LGU and 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 unloadings by species at the provincial, regional and national levels.

Sampling
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 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 188 sample landing centers were covered distributed in 58 provinces.
For the private, PFDA-managed fish ports and LGU-managed landing centers, all are completely covered (complete enumeration).

No deviation from the survey design.
Response rate for quarterly commercial fisheries survey is 100%.
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.

Face-to-face [f2f]
The Regional Director (RD) is responsible for the regional level monitoring and supervision of the survey operations of the Provincial Statistics Offices (PSOs).
The Provincial Statistical Officer (PSO) is the over-all supervisor in the province. As field supervisor, the PSO should ensure accuracy of data collection, completeness of the accomplished survey forms. As part of the PSO's tasks is the conduct of spot-checking and back-checking on the work of Statistical Researchers who act as data collectors for this activity.

QCFS Form 1 is a one-page questionnaire in the English language used in gathering information on the monthly volume and average price per kilogram by species of fish unloaded in traditional municipal fish landing centers during the reference quarter.
Name and classification of sample landing center are indicated in the questionnaire.Thirty-one major species are pre-listed with provisions for other species not mentioned in the list. These others or minor species are also included in data processing. However, only the 31 or major species are highlighted in all fisheries publications.
One questionnaire per respondent is used in the conduct of the interview. Name and type of key informant are also included in the questionnaire.
The same questionnaire is used every quarter. The same data structure is required in every quarter.
On the other hand, QCFS Form 2 is used in gathering administrative data on the monthly volume and average price per kilogram of fish unloaded from the PFDA, LGU and privately-managed Landing Centers during the reference quarter. It is also a one-paged questionnaire written in the English language. One form is intended for one landing center and covers one month information.

Data Processing
Manual editing of questionnaires at the provincial level is needed before the electronic data processing of survey returns.
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.

Data Appraisal
Since quarterly survey of commercial 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 auxilliary 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.
