Fish Farming In The United States

How to Begin, Breeds, a Business Plan, and a Beginner’s Guide to Fish Farming in the United States

Fish are generally raised for food in tanks and ponds as part of fish farming. Worldwide, industrial fish farming has already shown to be a successful industry. In Madison, Wisconsin, in 1887, the first fish hatchery was established in the United States; today there are thousands. Although some fish farms exist in the US that breed sport or ornamental fish, the majority are focused on food production.

Recirculation tanks, raceways, ponds, cages, or net pens can all be used to produce fish. The diversity of a prosperous fish farm is still based on consumer demand as well as the water’s quality, flow, oxygen content, and temperature. Natural fish output from the world’s lakes, rivers, and oceans won’t be enough to meet demand over the long term as the world’s population rises. Aquaculture is a crucial instrument for the effective and sustainable growth of seafood in order to meet global demand.Let’s look at additional details about fish farming in the USA down below.

Importance of fish farming in United State

According to the USDA, aquaculture is the raising of aquatic animals including fish, crustaceans, mollusks, etc. Fish, shellfish, and other aquatic items are sown, stored, and fed during the farming process in a controlled setting. Aquaculture seafood can be distinguished from wild seafood by its controlled environment. Fish farming is the practice of raising fish commercially for food production in ponds and tanks.

Commercial fish farming has already been touted as one of the most profitable enterprises in the world. Fish is a major food source, is in high demand, and with the increase in population, the prices of fish and fish-related products are increasing rapidly. Aquaculture represents a relatively small portion of agricultural production in the USA, but the industry is growing rapidly. Per capita, fish and fish product consumption in the United States has increased by more than 50% since 1970.

During the same period, global wild fish catches have not increased and, in some cases, decreased, while the cost per unit has increased. As demand for seafood increases in the United States and globally, aquaculture is becoming more critical. The USA is the world’s largest importer of fish and fisheries products and a significant player in global aquaculture, providing a variety of advanced technologies, feeds, equipment, and investment capital to other producers around the world.

While the amount of wild-caught seafood worldwide has remained the same year after year, the amount raised through aquaculture has increased dramatically. The USA imports about 70 to 85 percent of its seafood, and about 50 percent of that imported seafood is produced through aquaculture. As a result, some have hailed fish farming as a solution to the problem of overfishing.


However, these farms are far from benign and can cause serious damage to the ecosystem by introducing diseases, pollution, and invasive species. Damage from fish farms varies depending on the type of fish, how it is reared and fed, the size of the product, and where the farm is located. USDA provides leadership to ensure that a healthy fish farm sector can produce a safe and affordable supply of seafood products.

USDA scientists support and conduct research that develops new fish farm technologies that maintain a healthy ecosystem, assess aquatic animals’ health, and provides responsible water to consumers. In addition, raise awareness about the health and sustainability of agricultural products. Aquaculture research, education, and extension activities also create employment opportunities and train a skilled workforce in rural communities.

Accessible fish species in the USA

In the United States, there are five major fish species: catfish, trout, salmon, tilapia, hybrid striped bass, and two categories of non-food fish production: bait fish and decorative fish. So it stands to reason that access to geographical factors that assist production is necessary for a thriving aquaculture industry. It indicates that some regions of the US are more suited to aquaculture than others. For instance, the South outperforms the United States in production with yearly aquaculture sales of nearly $850 million.

It is due to the strong production of freshwater fish, especially catfish, in the waters of the Mississippi River and saltwater production in the Gulf of Mexico and the Atlantic Ocean. The West generates $ 475 million annually in aquaculture sales, mainly from Washington and California, which are major producers of shellfish but also strong freshwater and freshwater fish such as trout, tilapia, and salmon.

Catfish – The most popular species in the American fish farming industry. Usually, channel catfish have an effective rate of converting pellet feed into pounds of fish until they reach about 1 ½ pound. Catfish are a warm-water species that actively feed and thrive in warm temperatures and tolerate lower oxygen levels than many other species.

Tilapia – This non-native breed is another type of hot water. Production facilities are indoor, often greenhouse-type structures where fish often eat small particles of water that are involved in other aquaculture or hydroponic operations.


Trout – According to the Trout Farmers Association of the United States, 53 million pounds of trout, mostly rainbow trout, were raised in the United States in 2008, primarily for table fare. Trout farming requires a lot of care and high-quality, highly oxygenated cold water. Usually carried in outdoor raceways to transport water, the temperature should stay below 70 degrees.

Yellow perch – Although a small fish, yellow perch fillets are valuable. Farming this freshwater fish species in the United States has many advantages, such as feeding and training well to withstand crowds. However, the timing of effective changes and the contradictions that arise can complicate farming.

With any form, organisms are more concentrated, and thus a potential for things to go wrong. For example, it is concerned that salmon in the nets could endanger wild populations if they escape. However, fish farming in the United States certainly helps meet demand.

Pacific Cod – It is scientifically known as Gadus macrocephalus. It is a relatively large fish that grows up to three feet tall and can weigh up to 33 pounds when completed. The fish’s lower jaw has catfish-like whispers and three distinct dorsal fins. The Pacific Cod is found 3,000 feet around the Pacific Ocean and the Yellow Sea.

Fish is an essential food item in the United States, but the government regulates its fishing. Fishers have been allotted quotas using line fishing, pots, and trawls. But, then, there is not enough evidence to indicate the need to list fish as one of the most endangered species in the country.

Longnose Gar – Longnose Gar is an ancient freshwater fish found along the east coast of North and Central America. Archaeological evidence suggests that fish existed in Africa, Asia, Europe, and the Americas 100 million years ago. It is a freshwater fish; some 31 parts are found in salts per thousand. Fish live mostly in places with rock crops, plants, and nearby felled trees. They eat small fish, insects, and crustaceans.

Larger fish also prey on smaller fish, feeding primarily at night. The fish is 15 to 20 years old, with the oldest documentary ever being 39 years old. Unfortunately, their populations are declining due to overfishing, pollution, habitat loss, construction of dams and roads, and manipulation of water systems by human activities.

Sturgeon Chub – It is a small, slender fish with a long flat snout and grows up to three inches in length. The fish’s snout resembles the Atlantic sturgeon, hence the name sturgeon chub. Spawning occurs in June when the female lays her eggs on clean sand and sometimes on gravel. The main habitat of the fish is the fast-flowing rivers under the gravel.

Dusky pipefish – Dusky pipefish is a small fish about eight inches long. Dusky pipefish is a type of pipefish that extends from Bermuda in the western Atlantic Ocean, Chesapeake Bay (United States), the northern part of the Gulf of Mexico, the Bahama and Panama South to the Caribbean Sea.

Where does most fish come from in the United States? 

The United States mainly imports seafood from China, Thailand, Canada, Indonesia, Vietnam, and Ecuador. Top imports include freshwater fish, tuna, salmon, and groundfish.

Best fish farms in the United States 

There are over 1,800 fish farms in the United States, and most of them produce fish for consumption. The most popular fish raised in the United States is catfish, followed by trout, yellow perch, etc.

Ohio Freshwater Farms – Located in Ohio, it’s the largest indoor fish farm in the state. For any family, this is a great weekend break from city life.

Seattle Fish Company – The Washington-based company is known nationally for the fresh fish and seafood it produces. Some of the most popular items are salmon.

Icicle Sea Foods – With headquarters in Seattle, Icicle Sea Food is a major player in seafood processing and has vessel-based processing facilities in Alaska. In addition, icicle has several subsidiaries like Snopac Products, Smoki Foods, Icicle Seafoods, Kodiak Salmon Packers, etc.

Segrest Farms – Founded in 1961 in Florida, the farm is one of the largest ornamental fish producers in the United States. The manufacturer of its patented item GLOFISH, a tropical and freshwater fish variety, provide its products to public aquariums, pet stores for home users, and pisci culture research institutes.

Neighbourhood Fish Farms – Started in the 1970s, Neighborhood Fish Farms is one of Miami’s oldest marine and fish farms. The farm has been named one of the best for offering the best pocket-friendly prices with excellent fish quality.

Imperial Tropical – Established in Florida in 1970, Imperial Tropical has long been regarded as one of the best wholesalers in the nation. More than 100 pounds of premium tropical fish as well as farmed species grown in greenhouses are raised each year. The biggest agents and distributors in the US receive product deliveries from the farm.


Fish farming business plan in the USA

Choose the right place to farm fish

We need to consider some factors when choosing lands, such as soil quality, size, and water source. Choose a place that is big enough. Also, consider plans so that size does not limit you as you grow your fish farming business. Soil quality directly affects the quantity of fish you get. So, select a place with high soil quality. You must test the soil to ensure it is at least 20% higher and check the relative space level.

The area mustn’t be easily flooded, which will help prevent dirty water from entering the bond. There must be fewer rocks in the ground. The constant water flow is the most important factor in fish farming. For starting a fish farm in a city or town area, you must have access to municipal water sources. If you want to start in the village area, it is important to find a place near the river, lake or creek.

Learn the skills needed for fish farming

It is important to have some skills when starting a fish farming business. Some government fish farms run training programs. You can also participate in these programs to learn skills. It will teach you how to manage water quality, control disease, market, feed, and fish farming processes. There are some important things to starting a fish farming business. They are given below;

  • Make sure easy access to the pond for harvesting and feeding.
  • Check the water for starting to cultivate fish, both bacteriologically and chemically.
  • Understand the modern technical ways of risk assessment.
  • It is important to find suppliers for fish eggs and fish food.
  • Learn about the permissions and other legal requirements essential to starting a fish farming business in your area.

Procurement of equipment required for fish farming

Starting a fish farm is the same for small and large farmers. Below are some basic tools and equipment needed for a fish farming business.

  • Pumps
  • Fish Counter
  • Water Testing Equipment
  • Net / Sean Reels
  • Fish Tanks / Pond
  • Aeration Equipment
  • Fish Graders

Find the cost of starting fish farming

There are two major types of investment in this farming business: fixed capital costs and operating costs. Capital costs are land and building, pond construction, vehicles for transportation, several tanks, oxygen meters, etc. Operating costs are the purchase of eggs or fingers, labor, chemicals, medicines, taxes, insurance, fish feed, electricity, fuel, transportation, and other maintenance costs.

Before entering the business, carefully prepare a detailed calculation of the cost of your proposed fish farming plan. According to desired production and total land area, the calculation will change depending on the fish species you choose.

Feeding the fish

Fish species require good food to grow healthy. It means that buying supplements for fish will increase their productivity. Fish mostly eat algae, prepared fish food, or aquatic insects. You can buy pills made from soy, corn, vegetable products, and rice for feeding fish. Properly caring for and feeding your fish will make them gain weight faster and faster. You can increase the algae growth in the fish pond by just adding fertilizer.

They will grow faster, so they give additional food sources. It is best to feed fish species in the morning and the afternoon. Remember, you don’t leave unattended food in the fish pond for hours. It is because it can be toxic. When buying supplements, you insist on the species you breed because there are different supplements for different fish species.

Control diseases, parasites, and predators

Keep the fish pond clean to prevent the entry of parasites and diseases. You can get help from a professional on the right medicines that you can use to treat sick fish.

Fish harvesting

Harvesting is done by using a net or, in some cases harvesting all the fish to remove the entire water. You need to make sure that they are harvested properly and at the right time to provide quality fish to your customers.

Cage fish culture in the USA

Fish can be raised in four cultural systems: ponds, recirculating systems, raceways, or cages. A cage or net pen is a system that traps fish in a mesh enclosure. Cage and net-pen are different depending on their construction. A cage has a rigid frame (on each side), and a net pen is just around the top. Marine cages are called net pens, although they have completely rigid frames and vice versa.


Structural differences have little effect on production methods or the environmental impact of these systems. For example, cage culture uses existing aquatic resources (ponds, rivers, pathways, high seas, etc.) but captures fish in some net enclosure. The net retains the fish, making them easier to feed, observe and harvest. The mesh also allows water to flow freely between the fish and the surrounding water resources, thus maintaining good water quality.

Cage aquaculture involves raising fish in existing water resources, which allows the free flow of water. It is an aquaculture production system consisting of a floating frame, net materials, and a mooring system with a round or square floating net to catch large numbers of fish, and it can be installed in the pool, river, lake, or sea. Economically, cage culture is a low-impact farming practice with high profits and minimal carbon emissions.

Cultivating fish in existing aquifers removes one of the biggest barriers to fish farming on land – the need for a constant flow of clean, oxygenated water. Cage farms are designed to use natural streams, which provide the fish with oxygen and other suitable natural conditions while also removing waste.

A vast area of ​​brackish water available in the coastal states and underwater reservoirs can be better utilized by adopting cage culture. Because the investment is low and requires little or no land area, this farming method is ideal for small to medium-sized fishers as an alternative source of income.

Biofloc fish technology in the USA

Biofloc technology is an emerging, environmentally friendly, cost-effective way to grow sustainable fish. Previously, biofloc systems were used to treat wastewater and control fish production. It gained popularity and became the top choice for fish farmers quickly. Biofloc technology began to be used commercially on aquaculture farms in Central America.

The main highlight of biofloc fish farming is that it can reduce the overall cost involved in fish farming activities. Moreover, it is a sustainable process that does not harm the environment.

Frequently asked questions about fish farming in the USA (FAQ)

How does Biofloc technology work? 

In this technology, a biofloc collects microorganisms such as bacteria, algae, fungi, non-filaments, etc. The main function of microbes is to convert nitrogen-containing waste into the rest of the feed and the excretion of fish into a protein-rich diet. It works best in certain situations, including the air system, the external source of carbon, and sunlight. The nutritional value of fish food depends on the source of carbon, suspended solids, light intensity, salinity, bacteria, and other factors.

Which fish farm in the US is the biggest?

Martinsville is home to Blue Ridge Aquaculture (BRA), the world’s largest indoor fishery. BRA gathers more than 4 million pounds of protein in the form of tilapia annually in its 100,000 square foot facility on less than 2.5 acres.

How do I bring fish into the US?

The National Marine Fisheries Service (NMFS), the Fish and Wildlife Service (FWS), and the Food and Drug Administration (FDA) all oversee seafood imports into the United States.

Is American fish farming profitable?

Fish aquaculture is incredibly lucrative. The degree of profit is rarely larger than it is in other types of agriculture. A good retirement activity is fish farming. It takes a lot of physical effort and might be stressful to run a fish farm.
