Figuring the costs of beginning a fish farm takes time to plan and research. On an average he earns Rs 1.75 lakh from it by incurring an annual expenditure of Rs 25,000 only. The time of water contact with the media in the filter along with the depth and volume of the filter should be carefully calculated before the setup is made. The enterprise should have a proper and adequate supply of water from resources like ground, wells or springs, etc. 2. to cover the impact of different technical and economic factors on farm profitability (fishprices, types of fish culture, fish feeding methods, length of production cycle…etc). AquaMaof Aquaculture Technologies has been chosen to provide its recirculating aquaculture system (RAS) technology to West Coast Salmon, an industrial Atlantic Salmon production facility in Reno, Nevada. It is assumed that 40 cubic meters of the tank can produce about 4,000 fish in six months. The first phase of the project will deliver a 12,600 tonne production capacity HOG (head on gutted) from the second half of 2024. The cost and profits may vary depending on the country of the farm and on the species being cultured. DHAKA OFFICE.

The RAS fish farming unit needs or consumes less water when compared to other techniques of fish farming. Profit is not observed during the initial years of investment, but slowly as the production improves profits start coming in. These filters need to be dissolved oxygen to help the nitrification process. 3.3 How the fish business will be started. Generally, cultured fish need feed that is 3-5% of their body weight. Potential fish farmers should always have a detailed idea of how much capital the fish farming venture will need. A simple biofilter consists of a wheel, barrel or box, filled with media that facilitates a large surface area for growing nitrifying bacteria. He plans collaborating his agriculture, horticulture and farming knowledge into a subject of help to all those who wish grow crops, venture into farming or gardening. Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. Although, almost all places of Bangladesh are suitable for fish farming. Each of the component and its functioning is described below. These choices will be affected by the amount of capital you have, and the size of your target market. The main idea of the biofilter is to colonize nitrifying bacteria such that the water flowing through the biofilter when gets in contact with the bacteria on the surface media for a certain period of time converts NH₃ (ammonia) to NO₂ (nitrite) and to NO₃ (nitrate). For example, southern part of the countries are suitable for saltwater fish farming and the middle or northern parts are famous for freshwater fish farming. He worked for a leading African catfish RAS hatchery in The Netherlands and a RAS catfish farm for nearly three years before entering the fish feed industry.

The advantage with these filters is that they do not need the addition of oxygen before or after the nitrification process because the filter itself supplies the required oxygen to support fish respiration. <> The recirculation rate increases the Biofiltration and helps in greater nitrification with reduced ammonia levels. RAS can be located near the Every time the water is exchanged is termed as recirculation and its rate is defined per unit time. Most commonly used submerged filter is the fluidized bed reactor (FBR), which consists of fine particles like sand dense plastic and glass beads in a container. The water from the municipal water supply unit can also be used but should be treated to remove the chlorine, fluorine and other chemical substances.
