Abstract
Bangladesh has a large number of inland water resources, such as, rivers,rivulets, estuaries, heels, canals, haors, baors, lakes, ditches and ponds. Amongstthese resources the ponds play a significant role in producing fish in the rural areas. Major portion (83%) of protein needs of the village people is met from the pond Fish and other inland water bodies .The pisciculture in loflcls is a part of an extensive agricultural and economic activities in Bangladesh. But the i nformati on about the number and area of ponds, their uses, type of operation and possession,quanti.tY and value of yearly catch of fish, fish damage, etc. are not avai abe for taking further inten s ive development programmes on fisheriesresources. An uptodate inventory of ponds and fishing resources available there is necessary for devei.opment of fishery resources to meet the deficiency of proteln in the country. It, is possible to substantially increase the fish product i on t.hrougli proper uti]. i,zation of ponds and other .inland water bodies. For forinulatori of plan in respect of digging new ponds.re-excavation and reclamation of the old ponds, provision of rural credit for pisciculture, reliable statistics on inland water bodies and their condition are needed. The survey under report was undertaken in 1989 covering 552 mauzas scattered over the country to generate more dependable and comprehensive statistics on pond resources and revised, the changing sii:.uation over the period of 1982 when the first pond survey was under t1cen.This report contents are divided 'nto two parts. Part 1 contains, besides introduction, three more chapters. Chapter two explains survey methodology and chapter three explains the terminologies used in the survey.Analytical findings have been discussed in the chapter four mainly on national tables.The national tables are, therefore, not included in Part-Il. Part II contains the regionaltables. Schedules canvassed for data collection have been appended.

Version number
The Bangladesh Bureau of Statistics (BBS) conducted a survey of ponds in 1982 to establish a comprehensive statistics on inland fisheries resources.To obtai n comparative data and fo.r studying the changes overtime it was felt necessary to conduct another survey of the same nature. So a survey work plan was incorporated in the Second Phase Agricultural Census Project (1985-90) and the survey cas, accordingly, carried out in 1989.The i tenis covered in the survey were the number and area of ponds, depth of ponds, sources of water supply, seasonal water availability, type of operators, type of possession, annual
fish-catch by important varieties, quantity, value, sales proceeds and. own fish consumption, yearly fish damage, expenditure on piscriculLure, operational process and methods of fish catch, etc.The resuls obtained from this survey have been disaggregated into twenty regions due to a smaller size of sample. It is expected ttlat tne estimaLeu resu] ts based on collected information will be a reference document to the researchers, policy makers and administrators until detailed statistics in the fi old are made available by the next survey with an expanded sample size.

Sampling
Deviations from the Sample Design
A stratified two-stage random sample design with mauza as primary sampling units (PSU) and non-derelict ponds in selected mauzas secondary sampling units (SSU) was adopted for the survey. All the rural areas of Bangladesh were divided into three strata on the basis of the observations of the previous surveys of ponds held in 1978-79 and 1982. The results of the surveys showed that the ponds situated in the northern part of the country had greater use and the ponds in the southern part of the oountry had greater density.The first stratum contained all, the 5 greater districts of the northern part of the country,namely,Dinajpur, Rangpur, Pajshahi, Pabna and. Bogra on consideration of greater use of ponds. The second stratum contained 10 greater districts of the middle part of the country, namely, Comi 1l.a, Syihet, Dhaka, Faridpur, Jamal'pur, Mymensingh, Kishoreganj, Tangail , Jessore and Kushti.a.The third stratum which had greater concentration of ponds, contained 5 greater districts of the southern part of the country,namely, Chi.ttagong, Noaichaii, flarisal, Patuakha,ii and Khulnia.A uniform sampling fraction for all strata was fol lowed.
Weighting
Average catch of fish per acre as observed from the data of the previous survey suggests that the selected ponds also need to be further classified according to size into three categories at least. Therefore, in the selected mauzas,the ponds were classified on the basis of physical area into three categories as
follows:
1. 0.01 - 0.10 acre.
2. 0.11 - 0.30 acre.
3. 0.31 and. above acres.
The sampling fraction for the second stage was kept uniform for all the three categories in order to have a simple self weighting estimate. In all 11161 ponds were selected for collection of detailed information.

Type of Research Instrument
Mauza was the first stage sampling unit in the strata and the non-derelict ponds from listed total. ponds of each selected mauza was the second stage sampling unit. The ponds which were derelict were excluded from selection, 50% of the listed non-derelict ponds of a mauza were selected according to the procedUre of simple random sampling for canvassing the questionnaire. If the number of nonderelict ponds in a mauza were ten or less than ten, all of them wefe selected for detailed study. In all 552 mauzas were selected as primary sampling units and 11,161 ponds were selected as secondary sampling units for collection of detailed information.

Data Processing
Cleaning Operations
In all 3,998 schedules were used for taking information of 11,161 ponds.The collected schedules were manually edited with the help of an edit specification by the Statistical. Investigators and Statistical Assistants under the super -vision of senior officers of the Agricultural Census Project. The manually edited schedules were sent to the Computer and Data Processing Win(CDP Wing) for insertion of data as the tables provided. Some of the tables were prepared following the table formats used in the survey of ponds 1982 with a view to comparing data over the period. The national & regional level data are presented in this report. Zila level data could not be presented because of a smaller sample size.

Conditions
The actual field enumeration commenced on the 24th June, 1989 and ended on the 30th June, 1989. The reference time, date or period for collection of data varied according to the items of information. For collection of information regarding condItion of ponds, ownership of ponds, type of operators, type of possessiori,pond size,depth etc.the reference date was the day of enumeration and for thes items of information, on expenditure on fish cultivation, total catch,quantity of fish loss, sale of fish etc. the reference period was one year preceeding the day of enumeration. This refers to the status of the pond with regard to its use for fishing. The water unit may be in use currently (code 1); or with a little repair and introduction of spawn or fry it may be possible to use the water unit (code 2); or the unit may be derelict (code 3); i.e. it may require extensive repairs such as re-excavation, repair of embankments, clearing of weeds, etc, before it could be considered ready for use.The overall impact of gradual change on condition of ponds over the period of 1982 to 1989 was noteworthy and significant; because the percentage of derelict pond was 18.36 in 1982 while it was 9.42 in 1989. This trend brings a good impact on pisciculture by taking the derelict ponds under use or culturable over
the period.
