Abstract/ Executive Summary:

The effect of various factors on spawn and fingerlings production in government and private farms was measured in this study. Primary data were collected from 45 private and 11 government farms from 9 selected districts covering major fish seed producing areas of Bangladesh. Results from Cobb-Douglas production function analysis indicated that the included variables had some positive impacts on returns from spawn and fingerlings. No input was found to be over used and increasing returns to scale was observed. Tabular analysis indicated that higher amount of input use produced higher level of yield, gross return and net return. The government farms were under utilized. For increased supply of fish seeds in the country more amount of specified inputs (feed and fertilizer) should be used for producing spawn and fingerlings especially in government farms.

Keywords: Resource productivity, Economic performance, Fish seeds, Bangladesh

Location: Mymensingh, Gazipur, Jessore, Jhenaidah, Bogra and Camilla districts.

Start Date: 00-01-1997

End Date: 00-09-1997

Program Area: Socio-economic and Policy

Commodity: Aquatic animal

Objectives:

To analyze profitability as well as productivity of resources used in fish seed production under government and private management practices by types of farming.

Methodology:

Source of data: Primary data for this study was collected through personal interview of managers of FSMFs during January to September 1997 covering nine districts of the country. On the basis of easy accessibility and or high concentration of fish seed farms; Mymensingh, Gazipur, Jessore, Jhenaidah, Bogra and Camilla districts are selected in this study for both government and private FSMFs. However, Pabna, Natore and Joypurhat districts were selected only for government FSMFs. From these districts a total of 56 FSMFs were selected purposively of which 11 were government farms, 45 private farms. All the sample government farms were hatchery-cum-nursery. On the other hand, the sample private farms consisted of 21 hatchery-cum-nursery and 12 each from hatchery and nursery. Producing spawn in hatchery through induced breeding and rearing fingerlings in nursery ponds are two district stages of fish seed production. Therefore, inputs use and output gain in these two activities fare different. Costs and returns of producing fish seeds can be measured on per hectare and per Taka investment. However, costs and returns of FSMFs depend mainly on the utilization of available physical facilities. The farms which invest a huge amount for establishment of physical facilities, but can not utilize these rationally due to some social and technical problems, may not be profitable, specially in the case of hatchery. Therefore, measurement on per Taka investment was omitted in this study. Cost (depreciation) of farm structures/hatchery equipment, buildings and machinery (pump, tube wells) were not calculated. Because due to uncenainty, it is very difficult to estimate longevity of these items and there consecutive use in different years. Moreover, these items were jointly used for both spawn and fingerlings production and therefore costs for these items were not calculated. Only a particular type of costs like repair and maintenance were estimated. However, depreciation costs of minor equipment like hapa, dish plate for spawn production and dram and fishing net for fingerlings production were included in this study. Selection of model: The individual effect of inputs and factors used in fish seed production can be explained to certain degree with the help of production function analysis of various types. In this study, linear and Cobb-Douglas forms of production function were initially estimated to determine the effect of variable inputs. Finally Cobb-Douglas production function model was sorted out because of its better goodness of fit. For spawn and fingerlings production as well as for farms under government and private ownership separate equations were estimated. Input costs both for spawn and fingerlings production were considered as independent variables whereas the value of output (gross return) accrued from respective activities were considered as dependent variables. Multicolinearity was tested and necessarry independent variables were chosen finally to determine the factor contribution to spawn and fingerlings production. Eight inputs or independent variables were hypothesized to explain both spawn and fingerlings production in the study area.

Achievement/Findings:

The findings of the study indicate that there is a scope of increasing level of input use in both spawn and fingerlings production in government and private farms specially in government farms. The government fish seed farms were under utilized with lower level of input use and economic returns. Regardless the farm category the most effective inputs were observed to be feed and fertilizer. Hence fish seed production could be increased through intensification of all inputs used in the production process.
