RATIONALE
The Quarterly Aquaculture Survey (QAqS) is a quarterly survey that generates aquaculture production and area estimates. 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.
OBJECTIVES
The Quarterly Aquaculture Surveys (QAqS) aims to generate accurate and timely information on quarterly production, area and price by aquafarm type and species at the provincial level.

Sampling
The Quarterly Aquaculture Survey (QAqS) is a non-probability survey. Sampling 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 (8) 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 (5) sample aquafarms are selected. A total of 6662 sample aquafarms were covered nationwide.

Response rate for quarterly aquaculture survey is 73%. This accounted for farms in operation and those without harvest during the reference period.
QAqS is a non-probability survey. As such, no weighing procedure is applied.

The Provincial Statistics Officer (PSO) 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 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 and control of the said activities.
There were five (5) QAqS survey forms that were being used depending on the type of aquafarm. The data sets were the same for all the forms except for the section on species cultured applicable to 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
All survey forms are provided as external resources

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 then again inspected and reviewed for completeness, accuracy and consistency with other items.
