“…From Table 7 reveals that the benefit-cost ratio of fish farming for cash cost was 2.08 and benefit-cost ratio of fish farming for full cost was 1.86 (overall). These values are higher than the findings of Ferdoushi et al (2019) which were 1.34 for polyculture and 1.51 for tilapia monoculture. On the basis of the above discussion, it could be concluded that fish culture is profitable.…”

Shifting rice cultivation to aquaculture is a burning issue of agricultural land use policy in Bangladesh. The study was conducted to identify the reasons for change the paddy farming to fish culture and relative profitability of both enterprises randomly selected 50 sample farmers from Mymensingh district in Bangladesh. Primary data were collected through field survey. Mostly tabular analysis was done to achieve the objectives. To determine the net return of fish and rice production, profitability analysis was applied. The findings revealed that 70% of the respondents belonged to the age group of 30-64 years and average annual income and expenditure were Tk. 2333234 (US$ 24874.56) and Tk. 2025860 (US$ 21597.65), respectively. About 96 % of the respondents said that the profit motive was one of the main reasons to shift rice farming to aquaculture. Per hectare per/season gross margin and net return were Tk. 545994 (US$ 5820.83) and Tk. 487494 (US$ 5197.16), respectively for fish culture and Tk. 16404.00 (US$ 174.88) and Tk. 7064.00 (US$ 75.31), respectively, for rice cultivation. The BCR of fish culture and rice cultivation was 1.86 and 1.07, respectively (Full cost basis). Lower profit and scarcity of labour in harvesting period were the main problems faced by the rice farmers. Diseases and high feed cost were the main problems faced by the fish farmers. The fair price of paddy and the supply of paddy harvesting machineries need to be ensured by the government and other agencies to make profitable agribusiness by the rice farmers.

Aquaculture is moving on the way of intensification to fulfill the increasing demand of protein as capture fisheries are declining. The study was conducted to identify the socioeconomic characteristics, analyze the tilapia-carp polyculture system, profitability of tilapia-carp polyculture, and credit profile of the stratified randomly selected 50 sample farmers from Sherpur district in Bangladesh. Primary data were collected through field survey using an interview schedule. Some statistical measures like average percentage and ratios were calculated. The findings revealed that 36% of the respondents belonged to the age group of 25-29 years, 68% belong to medium family size (5 to 6 people), 44% respondents’ education level was higher secondary, 44% respondents’ primary occupation was fish farming and 46 % of were belonged to in annual income level of Tk. 150001-200000 ($1770 - $2360). Average fingerlings released in the tilapia-carp polyculture were 24240 per hectare per year. Most of the fingerlings collected from private hatcheries. The annual per hectare production of tilapia and carp were 8028 kg and 11085 kg., respectively. Per hectare per year gross cost, gross margin, gross return and net return were Tk. 1093008 ($12897), Tk. 759447 ($8961), Tk. 1735455 ($20477) and Tk. 642447 ($7580), respectively. The BCR of tilapia-carp polyculture for cash cost was 1.78 and full cost was 1.59. About 20% of the respondents took loan from different sources and they received 84.51% of their applied amount and 84.73 % of the loan money used in productive purposes. Mortality of fingerlings, the high price of the ingredient, low price of fish, high interest rate and non-availability of good quality fingerlings at proper time were identified to be the major problems in conducting pond fish production. Government and other agencies should come forward to provide subsidized feed, technical supports and credit facilities for the tilapia-carp fish farmers to make the enterprise effectively.

“…2 After the first month of growth, we also stocked the following Indian Major Carps: Rohu (Labeo rohita) and Mrigal (Cirrhinus Mrigala), weighing 125 g each, at a rate of 40 per pond, and Catla (Catla Catla), weighing 140 g each, at a rate of 20 per pond. The stocking ratio of Tilapia: Carp was thus 8:1, which represents a typical stocking strategy in the area (Ferdoushi et al, 2019;Heal et al, 2022).…”

On‐farm experimentation is an essential part of aquacultural product development, but experimental designs that are commonly used for intensive commercial aquaculture are usually not suitable for earthen pond aquaculture, particularly in smallholder contexts. Guidance for on‐farm testing of aeration technologies is similarly lacking. We therefore propose an experimental design (a cross‐over experiment) that has not previously been applied to aeration in pond aquaculture, and we demonstrate its use as part of the field testing of a novel solar aeration device in Bangladesh. The cross‐over experiment was less expensive than a large‐scale randomized control trial, and we show that relying on randomization alone would have produced inaccurate results for this experiment. We analysed dissolved oxygen and fish growth rates using regression techniques, including multi‐level regression and a generalized least‐squares model with a lag‐1 autocorrelation structure. We also describe the collaboration with a local farmer to build an experimental facility on his property, which was critical to the success of the experiment. The experiments showed that the device had a small impact on dissolved oxygen but was much less effective than commercially available products. On the other hand, the experimental design was effective and can be replicated to test other aeration technologies in on‐farm conditions.
