Abstract/ Executive Summary:

Fisheries sector has high potential for the economic development of Bangladesh. Bangladesh earns a considerable amount of foreign currencies by exporting fish, shrimps and other fisheries products. This study addresses profitability of tilapia production using benefit cost ratio. The study also examines input demand and output supply of tilapia farming in Bangladesh by applying a profit function approach. Results revealed that benefit cost ratio is greater than 1, means that tilapia production is profitable in the study area. Tilapia farmers are also responsive to changes in market prices of inputs and outputs. Tilapia price is the most dominant determinant of output supply and input demand. A 1% increase in tilapia price will increase output supply by 3.836% and increase demand for lime, fingerlings, feed and labour by 0.941%, 0.987%, 0.523% and 1.00%, respectively. Problem facing index analysis shows major problems faced by the farmers were low market price of tilapia, high prices of fish feed with adulteration and inadequate supply of good quality fry.

Program Area: Socio-economic and Policy

Commodity: Tilapia

Objectives:

The study aims to: (i) assess financial profitability of producing tilapia and (ii) estimate input demand and output supply elasticity’s of tilapia production in the study area.

Methodology:

The study was primarily conducted in the Trishal upazila under Mymensingh district of north-central Bangladesh. Mymensingh is called the ‘Mecca’ of fresh water aquaculture in Bangladesh because of the ‘blue revolution’ (Ahmed 2009). In Mymensingh region many farmers have devoted to tilapia culture in their fish pond because of its high income gain with low cost of production (Toma et al., 2015). Geographically, Trishal has been identified as the most important and promising area for tilapia culture, because of the availability of hatchery-produced fry, favorable resources, and climatic conditions, such as the availability of pond, warm climate, fertile soil etc. Some of the farmers in this area also received training in tilapia farming with the help of Department of Fisheries (DOF). Tilapia cultivation is much easier because of its some unique characteristics like high resistance to low quality water and tolerance to different types of diseases. Moreover, many pangas farmers have recently switched to tilapia farming due to lower market prices of pangas and hence has resulted in a moderate increase in tilapia production over the last few years (Ahmed et al., 2011). Most of the farmers of Trishal cultivate tilapia fish as they can harvest it twice in a year and also the cultivation is easy. Three villages namely Dewanibari, Kazir Shimla and Kanhar under Bailar union of Trishal was selected purposively for the study. A total of 58 farmers were in which 25 farmers from Dewanibari, 19 from Kazir Shimla and 14 farmers from Kanhar village were selected randomly based on data availability. Survey method is followed to collect information from the Tilapia farmers. The survey was conducted during June 2018 through pre-designed interview schedules. The collected data were summarized and analyzed to fulfill the objectives set for the study. Both tabular and statistical techniques were used to achieve the major objectives of the study. We apply two main analytical tools to address these two objectives. (a) Cost-Benefit Analysis (CBA) to determine financial profitability of tilapia production at the farm level and (b) translog profit function to estimate input demand, output supply and fixed factor elasticities of tilapia production in the study area.

Achievement/Findings:

The principal aim of this study was to assess financial profitability of tilapia farming and responsiveness of the tilapia farmers to input and output price. Results revealed that tilapia farming is profitable (BCR = 1.71). The average yield of tilapia was 36128.33 kg/ha and the net return of TK 1403315 per ha. Farmers are responsive to changes in market prices of tilapia and inputs. The overall performance of translog profit model reveals that the key variables included in the model were individually or jointly responsible for variation in the profit of tilapia production. In this regression analysis four explanatory variables and four fixed factors were used and all of the input variables has positive impact on tilapia production. The main influencing factors were lime price, feed price, education, male working person in tilapia farming. The major problems faced by the farmers were low market price of tilapia, high prices of fish feed with adulteration and inadequate supply of good quality fry etc. It is noteworthy that adequate supply of quality fry on time was most important to the fish farmers for improving their livelihood. In addition, they gave priority to credit facilities, low-cost of quality feed, training, and marketing channel to improve their existing livelihood status.
