Would you want to know if fish farms use antibiotics? Yes fish do use antibiotics
Several antibiotics, including oxytetracycline, amoxycillin, and sulphadiazine-trimethoprim, are commonly used in aquaculture to cure or prevent fish infections, based on my experience as a fish farmer.
Antibiotics can treat or prevent bacterial infections in fish farms, particularly in hatcheries. There are no reports from Ghana.
However, this has been shown to affect various bacteria, potentially harm receiving water bodies, and increase fish infections and antibiotic resistance in other regions.
This study aimed to evaluate specific fish farming techniques used by tilapia and catfish producers that could be linked to antibiotic resistance.
Method: In six zones of the Ministry of Fisheries, Ashanti Region of Ghana, 63 fish producers and nine fisheries officers were given validated questionnaires.
Outcomes/Discoveries: According to 73% of farmers, antibiotics are not used on their farms.
Two hatchery farmers use antibiotics (chloramphenicol or tetracycline) to feed fish, while three (4.8%) utilise tetracycline on fish farms.
Most respondents (93.6%) who utilise manure on fish farms do so primarily to fertilise fish ponds. They get their manure from commercial chicken farms.
As you continue to read, this study aims to evaluate the use of antibiotics in Bangladeshi inland and coastal fish farms and to pinpoint the contributing variables.

Now, let’s get started.
Are Farmed Fish Given Antibiotics
Because there are so many fish in aquaculture, bred fish are usually more likely to get sick or infected than wild fish. Antibiotics are often added to fish food to deal with this problem.
Fish farming is a relatively new way to farm, and each country has its own rules about how antibiotics can be used and how they should be monitored.
There are many kinds of antibiotics, but tetracycline is the one that people worldwide use the most.
This antibiotic is also often used to treat illnesses on the skin, in the digestive tract, in the lungs, in the urinary tract, in the vaginal area, and other places.
It also cures diseases like cholera, plague, malaria, and syphilis. It will no longer work if enough germs become resistant to this drug. The world will be a very different place.
Animals that are raised for food, on the other hand, are given a lot of different drugs, not just antibiotics. Some keep them healthy, eliminate pests, and help them grow better.
Drug use and drug residues in fish were the subject of a big study in Europe, the USA, Canada, and Japan. The survey found many violations.
What Antibiotics Are Used In Fish Farming
Fish farming is a relatively new way to farm, and each country has its own rules about how antibiotics can be used and how they should be monitored.
There are many kinds of antibiotics, but tetracycline is the one that people worldwide use the most.
Oxytetracycline was the most common antibiotic found in the samples. It is also the most common antibiotic used on farmed fish.
Even though the amounts of antibiotics in the fish samples were less than what the U.S. Food and Drug Administration allows, those amounts can still help bacteria become resistant to antibiotics.

Are Antibiotics Used On Farms
Antibiotics have been used widely in agriculture for many years, serving a variety of objectives and being utilized in people and companion animals.
Antibiotics are used in medicine and prophylaxis for humans, animals, and plants and stimulate animal development in food production.
However, the widespread and heavy use of antibiotics has led to the rise of bacterial infections that are highly resistant to drugs. The majority of antibiotics that are sold commercially cannot cure some of these infections.
A gene pool of antibiotic resistance has been established in the environment due to the widespread use of antibiotics in people, animals, and plants.
Resistance genes may be stored in pathogenic and non-pathogenic organisms that develop antibiotic resistance.
Antibiotic resistance genes and bacteria may be exposed to naive populations of animals, people, and microbes, potentially leading to transmitting such genes.
Studies have demonstrated that food, water, and direct human interaction may spread pathogenic microbes and potentially antibiotic-resistant genes from animals to people.
The primary method of giving antibiotics in salmon farming is through medicated meals, which causes antibiotics to leak into the environment.
What Are The Disadvantages Of Antibiotics On Fish Farms
It directly contributes to the growth of bacteria resistant to antibiotics, and transferable resistance genes can infect disease-causing bacteria, resulting in diseases resistant to antibiotics in fish and other aquatic animals and people.
In aquaculture, antibiotics are frequently used to prevent and manage illnesses. On the other hand, excessive or prolonged use of antibiotics leaves behind residues and gives rise to genes and bacteria that are resistant to the drugs (ARBs and ARGs).
Aquaculture ecosystems are familiar with antibiotics, ARBs, and ARGs. How they interact and their effects on biotic and abiotic media are still unclear.

Why Should Antibiotics Not Be Used In Farming
Prominent organization like the WHO and the European Medicines Agency assert that excessive antibiotic usage in agriculture raises the risk of antibiotic resistance in certain human illnesses.
For almost 60 years, antibiotics have been utilized to raise cattle. Antibiotics were first administered to animals in Europe to promote growth. In the EU, using antibiotics to promote growth was outlawed in 2006.
The World Organization for Animal Health states that while growth promotion is now prohibited in 108 countries globally, it is still permitted in at least 40.
Farming in the UK and Europe continues utilizing enormous amounts of antibiotics. Farmers may even use antibiotics that the World Health Organization has classified as “highest-priority critically important” for human use.
Furthermore, antibiotics are used to treat ill people in human medicine, but these valuable resources are frequently provided to groups of healthy animals in the farming industry. Group treatments account for 75% of farm antibiotic usage in the UK and 86% in Europe.
How Do You Control Bacterial Diseases With Antibiotics In Fish Farms
Since gram-negative bacteria account for most fish disease-causing microorganisms, erythromycin should only be administered when the sensitivity tests and culture results indicate its efficacy.
Furthermore, erythromycin works best when given by injection or feed; it is not a particularly effective bath therapy. The FDA has not authorized the use of erythromycin with fish for meals.
For the same reasons as previously, the penicillins—amoxicillin, ampicillin, and penicillin—work best against gram-positive bacteria like Streptococcus species.
As a result, these antibiotics are not a suitable first option for most bacterial infections in fish. The FDA has not approved the use of any penicillin in fish food.
On the other hand, fish bacterial infections are managed with antibiotics given in feed.
The most often used antibiotic has been chloramphenicol; new research has shown that while it has a broad spectrum of activity, it also has a number of unfavorable side effects.
For ten to fourteen days, 40–60 mg of chloramphenicol per kilogramme of live weight of the fish is given. Because of the aforementioned adverse effects, its use is currently decreasing.
Antibiotic sensitivity tests conducted on pathogenic bacteria should ideally be used to determine which antibiotic is appropriate for treating a certain condition.

Final Thought
Now that we have established that fish farms use antibiotics, Antibiotic resistance in fish farms in Ghana may be exacerbated by practices like using manure and the disposal of untreated waste, as most fish farmers surveyed stated.
Sulphonamides, however, are also effective in treating bacterial fish illnesses, particularly furunculosis in salmonids. They are added to the fish’s diet for eight days at 0.1–0.25 g per kilogramme of live weight.
