Series Information
Early publications of fisheries statistics of the Philippines integrated estimates of inland fisheries in the total municipal fish production. This is because, according to the fisheries law, the municipal fisheries include the fisheries in inland waters, as well as, those fisheries in marine waters, as long as fishing is operated with a fishing boat of not more than three (3) tons gross or no boat.
Estimates of annual production for inland fishing were gathered through observations of the then Fisheries Regional Offices (FROs) of the Bureau of Fisheries and Aquatic Resources (BFAR). A survey form for gathering the annual production data of lakes, rivers, canals, swamps, reservoirs, etc. was distributed to all FROs. The survey form is to be completed once a year for each province by the field staff of the FROs, relying on observations made during field trips made for other purposes. No statistical survey was done for inland fisheries till 1998.
When the mandate of collecting fisheries data was transferred from BFAR to BAS in 1987, annual estimates of catch from inland fishing households were based on time-series data published by BFAR.
In1997, the listing of all households engaged in inland fishing was conducted for the first time by the Bureau of Agricultural Statistics (BAS). Quarterly survey of households was implemented in the following years using the sampling frame developed in 1997. Data on volume and value of catch from inland fisheries are generated from quarterly surveys of households engaged in inland fishing.
Time series data on quarterly volume and value of inland fisheries by province are maintained by the Fisheries Statistics Division (FSD) of the Bureau of Agricultural Statistics (BAS) since 1998.

Abstract
Inland municipal fisheries include the catching of fish, crustaceans, molluscs and all other aquatic animals and plants in inland waters like lakes, rivers, dams, marshes, swamps, irrigation canals, creeks, etc. using simple gears and fishing boats some of which are non-motorized with a capacity of three (3) gross tons or less, or fishing not requiring the use of fishing boats.
Data on monthly quantity and value of catch by species by households for the quarter are gathered during the survey. The survey is implemented by the staff of the Provincial Operations Centers (POCs) of the BAS.
Despite the meager contribution of inland fisheries to the total fisheries output, fisheries statistics would not be complete without the estimates from this sub-sector. The number of households dependent on catch from inland bodies of water could not be ignored. Fish catch of the households is usually intended for home consumption. Members of the household who are involved in inland fishing are either full-time or part-time fishermen.

Sampling
Sampling Procedure
The sampling frame for inland fisheries is the list of all households engaged in catching fish in rivers,lakes, swamps, creeks, irrigation canals, dams, reservoirs, etc. The listing of households was done in 1997.
Using the principles of simple random sampling, sample households are drawn from the list. Number of sample households varies by province. Provincial Operations Centers (POCs) are instructed to interview a minimum of ten (10) households every quarter. However, several provinces maintained more than 10 sample households to get a more accurate basis of estimation for quarterly volume and value of inland production. Sample households are the same throughout the year. However, POCs are given prerogative to replace sample households that stopped fishing activity.
For 2009, 1,300 households were sampled out of 83,447 total households listed nationwide..

Response Rate
Response rate for quarterly survey of inland fisheries is 100%.
Weighting
A factor derived from the number of total households over the sample households is used to estimate monthly production of inland fisheries in the province . This factor varies from one province to another.

Data Processing
Data Editing
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 questionnaire
b) Correctness of unit of measurement used
c) Coding and encoding
d) Expansion factor used
Before the results are summarized, another series of consistency and completeness check is made during electronic data processing.
The processing of the results of the Quarterly Inland Fisheries Survey is part of the Municipal Fisheries Data Generation (MunDatagen) System using an Excel-based processing system. Data gathered from sample households are encoded in the provincial QIFS worksheet. These provincial worksheets are then compiled and summarized in the regional worksheets using an Excel-based processing system.

Data Appraisal
Data Appraisal
The accomplished QIFS forms serve as inputs for internal checks of the survey data. Units of measurement used for volume and price are reviewed. Levels of estimates are compared with those of the same quarter last year. Change in production is assessed if it reflects the real inland fisheries situation in the province. Some parameters used in the validation of inland fisheries are the number of households, productivity of sources of catch, fingerlings dispersal program of the BFAR.
