Agricultural Survey [ag/oth]
This is the first conduct of the Survey on Costs and Returns in Seaweed Production.
Seaweed has become one of the most promising commodities in the country because of its wide industrial and commercial uses. It is a major contributor to foreign currency earnings. Seaweed culture requires more labor inputs, thus, it offers more employment opportunities than other fishery activities, especially, for those idle labor forces in the coastal areas.
Due to the large potentials of seaweed, it has become necessary to ascertain the profitability of venturing into the production of this commodity. Its large contribution to the overall fishery subsector has also made it one of the top priorities for development. The Costs and Returns Survey of Seaweed Production was conducted to generate the needed information for promoting the sustained expansion of the seaweed industry in the Philippines.
The main objective of this study was to generate production costs and returns structure of seaweeds. Specifically, it was conducted to determine production cost structures, indicators of profitability such as gross and net returns, returns above cash costs, net profit - cost ratio, etc., information on the use of materials and labor inputs; and other related socio-economic variables including information on new production technologies.
Sample survey data [ssd]

INPUT USAGE such as quantity and cost of seedlings used, labor utilization (in terms of mandays) by type of farming activity, labor cost, source of labor and food cost incurred.
OTHER PRODUCTION COSTS such as cash and non-cash payments for salaries of employees and caretakers, cooperative fees, rentals of machine and tools, fuel and oil, transport costs of inputs, license, interest payment on crop loans and other production costs.
PRODUCTION AND DISPOSITION such as volume of seaweed production and its disposition in terms of sold, harvesters' share, other laborers' share, for home consumption, given away, wastage and other purposes.
BUYER INFORMATION such as major buyer of produce and the percentage of produce sold to each buyer.
PROBLEMS ENCOUNTERED such as problems affecting production and marketing of seaweeds.
ACCESS TO CREDIT such as amount and source of loan and interest rate per annum.
OTHER INFORMATION such as membership in seaweed related associations and benefits derived, access to extension services, future plans of seaweed farmers and their recommendations to improve seaweed industry.

Sampling
Sampling Design, Sample Size and Sample Selection Procedure
A two-stage sampling design was employed with the barangay as the primary sampling unit and seaweed farm operator as the secondary sampling unit. The list of seaweed producing barangays which was generated through the Aquaculture Farms Inventory was used as the sampling frame. The sample barangays were drawn using simple random sampling from the list of barangays with at least 90 percent cumulative share of seaweed harvested area and with more than five seaweed operators. Ten (10) barangays were drawn from each province except for Maguindanao, which has less than ten seaweed producing barangays. In this case, all barangays were covered by the survey.
The number of sample seaweed operators was proportionately allocated to the number of operators in the sample barangay. In each sample barangay, sample seaweed farm operators were identified using snowball sampling approach. Names and addresses of seaweed operators living in the barangay were obtained from the barangay council or from seaweed farmers association. From this list, the enumerator selected a seaweed farm operator at random. A set of screening questions was asked from the operator to determine if he/she met the criteria set for the survey. Whether the operator was qualified or not, he/she would then be asked to recommend others who they thought could qualify as survey respondents. From these names, the enumerator again selected a seaweed farm operator as the second potential sample for the survey. The process continued until the required number of samples was attained.
The survey was able to enumerate the following sample seaweed farm operators by province and variety planted.

Survey instrument
The questionnaire was a structured questionnaire written in English. It was designed in tabular form and some in question type format.
The questionnaire consisted of 8 pages covering 13 blocks as follows:

B. SAMPLE IDENTIFICATION such as the name, age, sex, highest educational attainment, main occupation and seaweed farming experience of the sample farmer/operator and the name of the respondent.
C. FARM CHARACTERISTICS such as area of seaweed farm, variety planted, culture method, loaction of seaweed farm, month of planting and harvesting, number of croppings and harvests.
D. FARM INVESTMENTS such as inventory of farm investments used, year and cost of acquisition, repairs and improvement cost and estimated life and usage in the focus farm.
E. MATERIAL INPUTS AND SUPPLIES contain the quantity and cost of material inputs used.
F. LABOR INPUTS such as labor utilization (in terms of mandays) and labor cost by type of farming activity, by source of labor and by sex and food cost incurred.
G. OTHER PRODUCTION COSTS cover cash and non-cash payments for salaries of employees abd caretakers, cooperative fees, rentals of machine and tools, fuel and oil, transport costs of inputs, license, interest payment on crop loan and other production costs.
H. PRODUCTION AND DISPOSITION such as volume of seaweed production (fresh or dry) and its disposition in terms of sold, harvesters' share, caretakers' share, other laborers' share, for home consumption, given away, used for seedlings, wastage and other purposes.

The Provincial Agricultural Statistics Officers (PASOs) and Assistant Provincial Agricultural Statistics Officers (APASOs) acted as overall supervisors in the provinces. As an immediate supervisors, they should see to it that the survey operation ran smoothly and within the target schedule. They conducted spot checking and backchecking, review of completed and edited questionnaires before submitting to the Central Office. A report on field data collection was prepared and sent by the POC to the Central Office.
The Regional Agricultural Statistics Officers (RASOs) were responsible for the monitoring and supervision of the survey operations in all the provinces within the region. The Statistical Operations Coordination Division (SOCD) at the Central Office monitored and coordinated the field operations.
The questionnaire was pre-tested in Zambales from February 13-15, 2008. On the average, the interview session took 15-20 minutes. After the pre-test, the questionnaire and the manual of operation were reviewed and finalized. Prior to the field data collection, training was undertaken to ensure that the concepts and procedures were correctly understood. The trainers' training was attended by selected BAS Central Office (CO) staff who became trainors at the BAS- Provincial Operations Center (POC) participated by the RASO, PASO and field staff. The field training included the conduct of mock interview, dry-run exercises, discussion of problems and issues and editing procedures. The BAS CO Staff who served as the trainors supervised the initial data collection activity of the POC staff. Upon return to the BAS Central Office, the BAS CO trainors prepared and submitted travel reports containing the activities done in the field (province) as well as the issues/problems encountered and their recommendations.
The field data collection was undertaken by the POC staff through personal interview of the sample farmers who passed the requirements of the survey using the set of screening questions. The interview was conducted in the local dialect of the province. Before the data collection, courtesy call to the barangay officials was done to get permission for the conduct of the survey in the barangay and explain the purpose of such activity.
Problems and issues encountered during field data collection were relayed to the BAS CO Staff or management for their information and action. The POC also submitted to the Central Office a narrative report regarding the conduct of the survey.
Data processing
Manual editing was initially done at the Provincial Operations Center during and after data collection using the CRS editing guidelines prepared by the Central Office. The edited questionnaires were again checked at the Central Office. Coding and encoding were likewise done at the Central Office.
Refer to Technical Documents for the Editing Guidelines.
Data appraisal
Not applicable.
The quality of the survey results were reviewed in terms of reliability and acceptability. A comparison with other related reference materials on input usage, labor utilization, production cost and return structure of seaweed was done.
