Based on drug class, the global market is segmented into pyrazinoisoquinolones, benzimidazoles, macrocyclic lactones, and other drug classes. The pyrazinoisoquinolones segment accounted for a majority share of 46.3% in 2025. Technological innovations in drug formulations and delivery is anticipated to fuel the segmental growth. The segment is expected to reach USD 195.5 million by 2035, growing at a CAGR of 5.1% during the forecast period.

  • Due to pyrazinoisoquinolones' (praziquantel is the most prominent one) effectiveness against trematodes and cestodes, they constitute the largest segment of the fish anthelmintic drugs market. These parasites infest the gills, intestines, and other body tissues of fish, causing serious health problems and significant losses for aquaculture producers.
  • The mechanism of action for pyrazinoisoquinolones is to disrupt the parasite's tegument, resulting in paralysis and eventual elimination from the host. The broad spectrum of activity against both freshwater and marine fish species makes these drugs especially suitable for high-value fish (e.g., salmon) and ornamental fish.
  • Additionally, fish aquaculture producers continue to use pyrazinoisoquinolones because they act very quickly, have limited side effects, and can be easily administered either by immersion or in medicated food.
  • Further, fish aquaculture producers are increasingly using these products to comply with existing international food safety regulations and meet the standards of export markets where fish must be parasite-free when exported.
  • The benzimidazoles segment was valued at USD 65.5 million in 2025. Benzimidazoles (albendazole and fenbendazole) are very important to the management of nematodes and flukes in aquaculture (particularly the treatment of nematodes) because they disrupt the formation of microtubules in the parasite, thus stopping its metabolism and reproductive cycle.
  • Furthermore, nematodes cause significant damage to fish by decreasing the amount of food consumed, growth rates, and feed efficiency, which can result in major economic loss for aquaculture facilities.
  • Moreover, benzimidazoles have many benefits, including their low cost, broad-spectrum activity ability to treat a large range of internal parasites, and efficiency; benzimidazoles can be administered by way of oral ingestion or immersion. Benzimidazoles are used in both the prevention and treatment of internal parasites to improve fish survival rates and productivity.

Based on target parasite, the global fish anthelmintics drugs market is segmented into nematodes, trematodes, mixed infections, and cestodes. The nematodes segment accounted for a leading share and was valued at USD 81.3 million in 2025.

  • Nematodes significantly affect a fish's productivity and health, as they cause a substantial loss in profit within a culture. They typically infect the intestines of fish, resulting in slower growth, converting less food into greater mass, and being more vulnerable to getting secondary infections.
  • When fish are raised within a concentrated environment or under high-density farming conditions, the risk of nematodes affecting fish is increased, and as such, effective measures to control outbreaks are needed in order to maximize both profitability and the welfare of the fish while maintaining low levels of environmental impact.
  • Additionally, the benzimidazole class of drugs, including albendazole and fenbendazole, has been widely used as anthelmintics in aquaculture to manage nematodes. These drugs work by interfering with the parasites' metabolic processes, ultimately resulting in their death.
  • The oral formulation of these drugs (medicated feed) works very well for treating nematodes, as it enables exact dosing and reduces stress for fish being treated. Newer formulations of the drug, such as pellet-type formulations with a coating, have improved the stability and effectiveness of benzimidazoles and other drugs for treating nematodes.
  • The trematodes segment held a revenue of USD 79.3 million in 2025. Flukes (trematodes) present a huge challenge to the aquaculture industry, especially where farming is done in high-density areas with warm water. The underbelly of these parasites has an effect by infecting the gills, skin, and internal organs of fish, which results in respiratory troubles, tissue damage, and increased risk for secondary infections.
  • Further, trematode infections lead to significant losses in aquaculture when not treated. Losses are attributed to increased mortality rates, reduction in growth performance, and decreased product quality. In order to control trematodes effectively, aquaculturists have begun using pyrazinoisoquinolones, specifically praziquantel, which is fast-acting and broad-spectrum. External fluke infestations are treated with immersion treatments, while internal infections are treated with oral formulations.
  • Furthermore, the mixed infection segment held a revenue of USD 61.5 million in 2025. The presence of mixed infection complicates treatment protocols because of the differences in the life cycles and drug sensitivity of the parasites and the length of time these parasites remain alive in the environment. Integrated chemical and biological therapies are rapidly becoming the most used methods by farms to control the potential for co-infection. The need for more than one treatment option increases the use of versatile anthelmintic products.
  • Moreover, the impact of multiple infections on growth rate, feed conversion efficiency, and quality of fillet samples is significantly greater than with a single species of infection. Farms experience greater economic losses due to the presence of mixed infections, thus prompting them to use an ongoing, preventative regimen of treatment with multi-class products that are effective against a range of parasite hosts.

Based on formulation, the global fish anthelmintics drugs market is segmented into oral, immersion, and injectable. The oral segment accounted for a majority share of 60.5% in 2025.

  • The oral formulations segment is an important part of the fish anthelmintics market because they are used to target worms that can live inside the fish body, specifically nematodes and cestodes. Oral formulations are delivered through medicated feed given to fish during the normal feeding process, which is advantageous for aquaculture organizations.
  • Oral formulations allow for accurate dosing over extended periods of time, making them useful both for preventing infection and treating chronic infections in fish.
  • In addition, the increased use of oral formulations has also increased as the specialists working in intensive aquaculture systems are adopting oral formulations due to the convenience and low cost associated with using this type of product to control parasites, which are a major threat to the productivity of aquaculture systems.
  • Further, advances in technology related to the formulation of feeds have allowed for the development of coated pellets and controlled-release formulations, which have improved the stability of actives and reduced the amount that leaches into the water environment during feeding, thereby improving the effectiveness of treatment and reducing the environmental impact of anthelmintic treatments.
  • Immersion treatment is a standard method of utilizing anthelmintic medication in fish farming that is utilized to treat external parasites (such as monogenean flukes) and the larval stages of internal worms. It involves dissolving the medication in water and placing the fish into this solution for a specified time, which ensures all fish in the population are treated uniformly.
  • Additionally, the immersion technique is very helpful in high-density fish farming systems, where parasites can quickly spread from one fish to another, so immediate treatment is critical to prevent outbreaks.
  • One of the main advantages of the immersion treatment method is the stress reduction for fish that would result from administering individual doses; therefore, it can be used readily in large-scale fish farms and hatcheries.
  • Furthermore, immersion treatment results in a rapid response capability in emergencies, thereby reducing the likelihood of high mortality rates and financial losses.
