Fish farming is basically the commercial raising of fish in tanks and ponds for food production. Commercial fish farming has established profitable commercial opportunities worldwide. It is well known that fish is an important source of food and protein, so the demand and price of fish and fish-related products have increased rapidly along with population growth.
Fish farming is a hot topic in some fields. Environmentalists often argue that fish farms are bad for the environment, while advocates point out that fish farms are an important source of high-quality protein. Whatever side of the debate you take, one of the great advantages of fish farming is that it's a great entrepreneurial opportunity.
1.Benefits Of Fish Farming
(1)Fish is Popular
By far, aquatic products are the most popular animal products in the market, accounting for more than 60 percent of meat products in the market.
(2)Fish is Source of Protein
Fish is one of the main sources of protein. It is a good source of low-fat protein, rich in omega-3 fatty acids and vitamins such as D and B2 (riboflavin). Fish is also rich in calcium and phosphorus, and is also an important source of minerals such as iron, zinc, iodine, magnesium and potassium.
(3)Fish Sells Quick
Fish sells faster than any other animal product on the market and is cheaper than meat, so fish is the first choice in terms of affordability.
(4)Fish Matures Quickly
Fish grows very quickly because the practice of fish farming makes it possible for farmers to increase the growth rate of fish with certain feeds, thus ensuring that you harvest and sell them in a short time.
(5)Fish Contains Omega-3
Fish is the biggest source of omega-3 fatty acids, which are great for the heart. Omega-3 helps keep our heart and brain very healthy. Since the body does not produce omega-3 fatty acids, food is the only source, and this is where fish live.
(6)Fish Farming is Profitable
Fish farming is very profitable. With proper planning and good management, profits can easily be made within six months.
(7)No Environmental Hazard
Fish farms do not cause any harm to the environment. Unlike poultry farming, you can set up fish farms anywhere, including residential areas. If you have specious compound, you can easily set up a small fish farm in your backyard without any supervision.
2.Disadvantages of Fish Farming
(1)Water Pollution and Infections
Farmed fish are usually treated with antibiotics, disinfectants and pesticides. These chemicals and fish waste may enter the surrounding fresh water and cause water pollution.
Moreover, crowding of fish in one area can lead to the death of some fish. Dead fish promote the growth of bacteria and other infections that can threaten entire fish populations in the water supply. In addition, the crowding of fish leads to frequent close contact, so the disease can spread easily among the fish.
(2)Expensive to Set Up
Initial installation costs in fish culture can be high due to the need to install fish, hatcheries, and provide processed fish feed pellets. In addition, the most expensive part of pond farming, as opposed to fish farming in large bodies of water, is digging, bringing water in and out of the ponds.
Farmed fish have a limited gene pool during reproduction. This increases the risk of genetic disease in fish offspring.
Hope this article can help you know more about fish farming, if you want to build your own fish feed plant, You can continue reading below:
Fish feed production line is one of complete animal feed processing line, which is newly developed to meet the demand of intensive production of animal fish feed pellets. And this machine can produce floating fish feed, sinking fish feed, pet feed, livestock feed, etc.
1.Fish feed making raw materials: Plant protein comes from corn, rice, wheat, soybean, peanut cake powder, etc; Animal protein is from fish meal, shrimp meal, crab meal, sleeve-fish meal and so on you can add other ingredient according to requirements and eating habits of animals.
2.Production capacity: 80kg to 20 ton per hour.
The processes of complete fish feed manufacturing plant mainly include material grinding, material mixing, pellets extruding, pellets drying, and pellets packing.
(1)Feed grinding - fish feed hammer mill crusher machine
The raw materials should be grinded to the required size by fish feed grinder. Crushing the material can improve the water stability and digestibility of feed pellet.
(2)Feed mixing - use fish feed mixer
Mixing the material thoroughly can ensure extruding efficiency and improve the feed quality. Horizontal ribbon feed mixer or double-shaft mixer or feed ribbon type mixer.double-shaft efficient mixer can be applied to mixing powdery, granular, flaky and blocky materials while feed ribbon type mixer is mostly used for mixing powdery materials.
(3)Fish food extruding- fish feed pellet mill machine
Dry type fish feed pellet making machine and wet type fish feed pelleting machine. The wet type extruder has the conditioner and need a steam boiler, while the dry type fish feed machine does not need. The former is suitable for large fish feed pellet plant, while the latter is better for small and medium feed pellet user or fish feed pellet production plant.
(4)Fish feed pellets drying- Pellet Extruding Drying Machine
Belt dryer. We provide multi-layer mesh belt feed pellet dryer for drying the pellet coming out of the fish feed making machine. The pellets are spread evenly on a wire mesh belt conveyor and conveyed within the dryer. Hot air passes through the pellets and brings away the moisture.
(5)Fish Feed Pellet Cooler For Fish Feed Production Line
Fish feed pellets cooling is reduce the temperature of food.
(6)Fish feed pellets packing - Fish Feed Packaging Machine -electronic packing machine
The fish feed pellets packing machine consists of automatic weighing machine, conveyor, bag sewing machine and automatic control box. It can weigh the pellets fast and precisely. Simple structure, reliable operation.
