2.1 Fisheries sub-sector in the economy of Bangladesh
People in Bangladesh depend mostly on fish as their principal and cheap source of animal protein. Fish is an important component of total human food consumption. Historically, thousands of rice varieties and hundreds of fish species contributed to the diet of the people in Bangladesh[7]. About 22% of daily dietary protein required should come from animal sources. Fish alone contributes about 74% of total animal protein.
Fisheries are an important sub-sector of agriculture and have been playing a significant role in nutrition, employment, foreign exchange earnings and food supply. Agriculture contributed 32.24% to the Gross Domestic Product (GDP), and the fishery sub-sector contributed 3.10% to GDP in 1995-96 (BBS, 1996, p.477). About 12.05% of the population depends directly, or indirectly, on fishing and ancillary occupations. The fishery sub-sector provides full-time employment to over 1.2 million people, which constitute about 3% of the active population (BBS, 1996). Another 11 million people indirectly earn their livelihood from activities related to fisheries (FFYP, 1998, p. 248).
2.2 Fisheries sub-sectors
The fisheries in Bangladesh fall broadly into four categories:
Bangladesh has a vast potential for expanding fisheries within her boundaries, as well as in her territorial and economic zones at sea. Inland capture fisheries consist of 4 047 316 ha of water area (rivers and estuaries 1 031 563 ha, beels 114 161 ha, Kaptai lake 68 800 ha and flood-lands 2 832 792 ha), and inland culture fisheries cover 290 374 ha of water area (ponds 146 890 ha[8], baors 5 488 ha and shrimp farms 137 996 ha). Total area of inland water is 4 337 690 ha. Total catch from capture fisheries accounts for 48.42% of the total, and culture fisheries contributed 30.14%, making production from inland fisheries 78.56% of the country's total production (marine fishes contributed 21.44%; DOF, 1995/96, Table 1). The country's total inland fish production is among the highest in the world, ranking third behind China and India (World Bank, 1983)[9]. Marine fish production is more capital-intensive than inland fish production.
2.3 Trends in fish production
By virtue of Bangladesh's geographical location close to the great Himalayas to the north and the Bay of Bengal in the south, the country has the unique advantage of possessing the world's largest river delta - the Ganges delta, which offers vast potential for various kinds of fisheries in its fresh-, brackish and marine waters. The country is endowed with vast water resources comprising innumerable rivers, tributaries, canals, lakes, oxbow lakes, land depressions and huge floodplains during the wet season (five to six months). Several large river systems, such as the Ganges, the Meghna, the Padma, the Jamuna and the Brahmaputra, flow from the Himalayas to the Bay of Bengal. The inland waters of Bangladesh are home to 260 indigenous and 11 exotic species of fish and 24 species of prawns. The marine waters of the Bay of Bengal team with about 475 finfish and 38 shrimp species (Rahman, 1995, p.2).
We estimated trends in fish production for both inland and marine waters sources for the last decade. Inland water sources comprise:
Marine capture is divided into industrial-scale fisheries and small-scale fisheries.
We estimated changes in total fish catches from 1986-87 to 1995-96 (last data available). Estimated growth trends are shown in Table 1. Over the last decade, overall yield from inland-water fish production has increased at a rate of 5.67% per annum, open-water fish production has increased by 4.68% per annum; catches from closed waters have risen by 8.53%, and production from fish ponds has grown by 8.18% per annum. All increases were statistically highly significant. Catches of marine fishes increased by 2.15% per annum, yet industrial catches from trawlers did not rise significantly, whereas catches from small-scale fisheries increased 2.21% per annum.

SOURCE: Fishery Statistical Yearbook of Bangladesh 1995-96, P. 43. Department of Fisheries, Govt. of Bangladesh (See Table 1.2, present text).The country's overall fish production has increased at a yearly rate of 4.88% over the last decade. Total fish production from inland waters rose 140% in 1995-96 above production levels in 1991-92 (Table 2). Inland open-water fishery has increased by 127%, and inland closed-water fishery has increased by 167% in 1995-96 over production levels in 1991-92. Among closed-water fisheries, production from ponds rose by 158% during the first part of the 1990s. During the same period, production from rivers and estuaries also increased by 133%. The increase is mostly attributed to improved fishing techniques, to the intense use of nets placed in currents and over-fishing commonly owned water bodies. In 1995-96, the share of production from inland waters to total production for the country was 78.56% (marine fisheries contributed 21.44%). Share of production from brackish water to total fish production amounted to 5.43%[10]. During 1992-93, ponds covered only 3.5% of total area of inland waters and contributed 26% to the total of inland fish-production. In 1995-96 the contribution of ponds to total inland fish production amounted to 31%. Total fish production for the country in 1996-97 was 13.70 lac tons (1.37 million t), of which 10.79 lac tons came from inland water bodies and 2.94 lac tons from marine fisheries (DOF, 1998).NOTES:

2.4 Ownership of ponds and size of ponds
Historically, almost every family owned at least one pond in the vicinity of the homestead. These ponds were dug to retain perennial waters for the family household for bathing, cleaning (utensils/clothes) and also, in some cases, to be used for drinking water. Today, few people use pond water for drinking water since the use of hand tube-wells is widely spread in rural areas. These ponds were family property and were shared by members of the household. Joint ownership of ponds was common. Only two decades ago, few fish were cultured in family ponds. During the monsoon season, regular floodwaters used to supply the ponds with fingerlings through narrow canals that were maintained for this purpose (in flood-free areas, ponds were refilled each year by rain waters). Thus, stocking of fish occurred naturally. This scenario has changed to a large extent, since 53% of ponds suitable for culture are now being utilized for fish-culture activities (stocking, artificial feeding and fertilizing are pursued to different degrees) in rural areas.

SOURCE: Fishery Statistical Yearbook of Bangladesh 1995-96, DOF, p.43Usually, richer families had larger ponds and more than one each for males and females in the houses. Of the 619 farm households sampled, 94% of small farm households (1 to 50 decimal of land) owned their ponds outright or shared ownership. Families owned 99% of the ponds on medium-sized farms (51-250 decimal land) and on large farms (more than 250 decimal of land). Average size of pond (water area) was 10, 16 and 26 decimal for small, medium and large farms respectively. Average pond-size (water area) for all farm households was 19 decimal.
Data on average size of pond and area under fish cultivation for the 116 farm households engaged to various degrees in fish culture are presented in Table 3.

SOURCE: Field Survey, 1999.These farmers pursued fish culture as an important source of income and produced fish for sale in the market. Average pond size was 71 (0.29 ha) decimal. All ponds were used for fish culture. Of total ponds (on average, we surveyed 36 in each village; for 68 000 villages, the total number of ponds was approximately 2 448 000), 53% of ponds were under fish cultivation. These cultivated ponds were usually big and covered larger water areas than derelict tanks and fallow suitable for cultivation. During 1998, the number of ponds increased by 5.02% (newly excavated ponds) in the surveyed villages. About 55% of ponds were more than 30 years old, 30% were built within the last 15-30 years, and the rest were less than 15 years old. Of all old ponds, 26 ponds were re-excavated over the last 10 years. We saw a surge in activities in fish-culture in village ponds as a means of increasing income through the sale of different kinds of fish. Eighty-five percent of farmers had up to 15 years of experience in managing fish culture in their villages. Farm households that were experienced in managing pond aquaculture for more than 16 years amounted to 15% (Sanjeeb, 1999). The figures show that pond aquaculture has spread widely since the mid-1980s. Income from fish, as a share of total family income, is shown in Table 4. Income from the sale of fish is higher for households of all farm-sizes than from any other source, including crop agriculture. Small- and medium-sized farms derived income mostly from selling fish. Households of all farm-sizes that were engaged in activities related to culturing fish, rented out part of land they owned to others for cultivation (i.e., as farmers, they have a share in the operations).

* Others include contractors in rural work-programmes.
Fish-farming households of all sizes leased out part of their cultivable croplands to others, probably in order to turn more of their attention to fish-culturing activities. However, few households were solely involved in aquaculture.[11]
Income from the sale of fish constituted a large share in total income for fish farmers. Fish sales contributed 42% to total family income, followed by income from marketed surplus of crops (20%, Table 4). Most income (57%) of medium-sized farms was derived from selling fish, amounting to 45% for small farms and 36% for large farms. Income of large farms from marketed surpluses of crops was 26%, 18% for medium-sized farms and 9% for small farms (large farms may have more marketable surpluses of crops). That is, of disposable income (cash income minus taxes and debts), income from fish represented a significant portion of fish-farming families' earnings, irrespective of the size of their farm. Farmers are starting to pay more attention to markets when managing their crop products and fish-cultural activities.
Families pursue activities in aquaculture as part of a multi-enterprise farming-system. However, today a new class of business entrepreneurs and retired public servants is also engaged in pond-aquaculture (excavating several new ponds) in the central region of Bangladesh, areas like Gazipur, Trishal, Bhaluka and in Savar, sometimes in conjunction with other businesses (e.g. raising poultry, dairy farming, etc.). Fishpond aquaculture is becoming more commercialized as agricultural development in the country progresses.
2.6 Prevalent production systems and management practices
Fish production depends on:
Production practices are affected by:
Fish farmers usually practise polyculture. Major species stocked are rohu, catla, mrigal, kalbaos, silver carp, grass carp, carpu, mirror carp, tilapia, nilotica, shorpunti, Thai sorpunti, African magur, etc. (scientific names are provided in Appendix 3).

SOURCE: MAEP Survey, 1994, p.51 (conducted by the author)Percentages of fish farmers culturing different species and information on per hectare production under M-AEP project area are provided in Table 5. Per hectare, average production was 1.56 t of fish. In the present study, yields per hectare for differently sized groups of farms are shown in Table 6. Medium-sized farm households had the highest yield of fish per hectare, which amounted to 2.13 t/ha. Large farms produced 2.10 t, small farms 1.73 t/ha; and average yield was 1.96 t/ha. Fish production has increased on all levels.NOTE: (MAEP - A Bangladesh/Danida joint project for promotion of aquacultural activities. The project covers greater Mymensingh District, Lakshmipur and Patuakhali. The project arranges training of farmers in fishpond culture and semi-intensive method. It also provides credit support through NGOs).

SOURCE: Field Survey, 1999Polyculture is widely practised on small-scale private fish farms. The cultivation of shrimps in brackish waters and large-scale industrial production in the private sector are practised as monoculture-operations (see a case study on large-scale industrial production of nilotica by a public limited company - Appendix 4). Other than household ponds, natural, closed-water fisheries include baors (ox-bow lakes - total area 5 488 ha) haors (depressions in floodplains) and beel (permanently filled depressions)[12]. There are publicly owned waters ('Jalmahal' in Bangla), which are regulated by the Land Revenue Administration of the Government. Land Administration's prime motivation in leasing out 'Jalmahals' is to maximize earnings through open bidding ('ijara') to interested parties, regardless of whether they are fishermen or fish farmers. These professional groups are politically and economically vulnerable and weak. The Department of Fisheries is officially responsible for overseeing biological aspects of the management of these 'Jalmahals'.
Cultured species, their stocking-rate per hectare and share of cost for each species' fingerlings are presented in Table 7. Stocking-rate per hectare seemed high due to the high numbers of fish fries included. Species preferred for cultivation in the villages surveyed were rohu, catla, mrigal, pangas, silver carp, mirror carp, shorpunti, grass carp, etc. Share of cost of pangas fingerlings was noticeably higher (29%) than for other species. Knowledge about managing fish ponds has certainly improved from earlier times. Costs incurred for fingerlings per hectare are shown in Table 8. Today, all fish farmers use chemical fertilizers and manures (cow-dung, compost), but they do not all follow standard recommended doses (inadequate doses are common) mainly because of ignorance and lack of information. The share of cost for fingerlings was the highest (35%) in total cost incurred per hectare, followed by the cost of feed (34.56%). Cost of labour (for draining ponds, cleaning, applying fertilizer, liming and applying medicine, etc.) constituted 13% of total operating cost. Total cost per hectare amounted to Tk 51 118 in current prices, and total sales revenue earned were Tk 91 177 yielding a net return of Tk 40 059 per hectare under low-intensity production practices.

SOURCE: Field Survey, 1999.Ponds only used for fish-culture were few (4%). Ninety-six percent of fish ponds were also widely used for bathing, washing dishes and clothes and for rearing ducks. Fish farmers and other water users, by and large, are not aware of health hazards when using pond waters where chemical fertilizers, manures and medicine had been applied.

Leasing ponds for fish culture (from co-owners or from others in the village) has emerged as a business venture in rural areas. 'Joint' ownership of a family pond used to create a problem as to who would be responsible for managing a jointly owned fishpond dedicated to aquaculture. Today, it is common practice that one or more family members, singly or jointly, lease a pond from co-owners for a period of 1-10 years (as was observed in the areas surveyed). They pay other members cash-rent in advance for culturing only fish. User-right of the pond remains as before. Some people may lease more than one pond at a time to culture fish. Types of management of fish ponds in the villages surveyed are presented in Table 9. Management under a single authority is preferred for both family-owned ponds and for leasing ponds.
