Agricultural Survey [ag/oth]
QAqS is a quarterly survey that generates aquaculture production and area estimates. It has been regularly conducted since 2002.
The Quarterly Aquaculture Survey aims to generate accurate and timely information on quarterly production, area and price by aquafarm type and species at the provincial level. It asks for the actual level of production, area harvested and price for each species during the reference quarter of the current and previous year from the sample operators in the top producing municipalities. Fisheries outputs form part of the estimation for the performance of agriculture and eventually, of the National Accounts for the generation GVA, GNP and GDP.

Sampling
The Quarterly Aquaculture Survey is a non-probability survey. Selection of farms was done by aquafarm type in the province. By aquafarm type, top producing municipalities are those with cumulative share of at least 80% to total area based on Aquaculture Farms Inventory (AqFI).
For each municipality, eight sample aquafarms are selected, if the number of aquafarms in the municipality is more than 25. If the number of aquafarms is less than 25, five sample aquafarms are selected. A total of 6,662 sample aquafarms were covered nationwide.
Response rate is 73%. This accounted for farms in operation and those without harvest during the reference period.
QAqS is a non-probability survey. No weighing procedure is applied.
Survey instrument
There were five QAqS survey forms that were being used depending on the type of aquafarm:
- QAqS Form 1 - Fishpond
- QAqS Form 2 - Pen and Cage
- QAqS Form 3 - Oyster, Mussel and Seaweed
- QAqS Form 4 - Hatchery
- QAqS Form 5 - Other Freshwater Farms
The datasets were the same for all the forms except for the section on species cultured applicable to the type of an aquafarm.

The Provincial Statistics Officer (PSO) provides the overall 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 PSO conducts spot checking and back checking activities. The Statistical Operations and Coordination Division (SOCD) Chief may also provide another level of supervision. And sometimes, Central Office personnel may be available to provide support.
The regular staff of the PSA Provincial Statistics Office (PSO) or the Statistical Researchers hired conduct the interviews of the owner/operator and/or caretaker of the sample aquafarms using the survey forms. They also inquire from key informants about the production of most of the operators in the municipality and conditions affecting production. Key informants may be Municipal Agricultural Officer (MAO), barangay official, official/member of aquafarm operators' organization and other knowledgeable persons regarding aquafarm operation.
Data processing
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 again inspected and reviewed for completeness, accuracy and consistency with other items.
Data appraisal
