Aquatic animals, from koi fish and turtles to sharks, require specialized veterinary care, including delicate surgical procedures. While surgery on land animals is well understood, the world of aquatic animal care is a field that continues to evolve, requiring precision, innovation, and specialized instruments. Just as in human and traditional veterinary medicine, surgical instruments play a crucial role in ensuring the success of these procedures.

In this blog, we will explore how tiny tools are used to perform surgeries on exotic fish and aquatic animals, examine the challenges faced in this unique field, and discuss advancements that are revolutionizing aquatic animal care.

The Special Challenges of Aquatic Animal Care

Aquatic animals, unlike land animals, have special challenges associated with surgery. Physiology, anatomy, and the fact that they require an aquatic environment create a challenge that requires specialized equipment and skills. Among the main challenges are:

1. Breathing and Water Dependency: Aquatic life relies on water to breathe and eat. Maintaining their viability in surgery may involve new techniques like artificial gill ventilation or continuous water perfusion of the gills.
2. Fine Tissues and Scales: Thin, translucent scales or skin are typical of most fish and reptiles. Suturing and cutting need ultra-fine instruments to avoid trauma.
3. Anesthesia Considerations: Fish and turtles are anesthetized with water-soluble anesthetics like MS-222 (tricaine methanesulfonate), which need to be dosed carefully and watched.
4. Operating in a Wet Environment: It is difficult to keep surgical areas dry. Some procedures demand creative solutions, like working in a partially drained tank or using waterproof barriers to define the surgical area.
5. Size Range: From a small goldfish to a behemoth shark, aquatic surgeries have a diverse range of sizes and hence a variety of surgical instruments.

Essential Surgery Tools for Procedures on Aquatic Animals

A range of high-precision instruments is used by veterinarians and aquatic experts in performing surgeries on exotic fish, turtles, and sharks. Among the most regularly used instruments are:

1. Microinstruments to Use for Surgeries on Fish

For little fish such as koi fish, betta fish, and goldfish, precision is crucial. Microtools used in ophthalmic and neurosurgery procedures are mostly used in adapting aquatic surgeries. These are:

• Microscissors: Employed in dissection of delicate tissues and suturing.
• Fine Trocars and cannulas: Utilized in draining cysts or clearing obstructions in small fish.
• Microsurgical Forceps: Best for holding small structures with minimal trauma.

2. Turtles’ Bone and Soft Tissue Instruments

Turtles, with their hard shells and distinctive physiology, need special instruments to fix shells, close wounds, and perform internal surgery. Standard equipment is:

• Bone Saws and Rongeurs: To saw through the shell where required, particularly in cases of trauma.
• Suture Kits and Staplers: Utilized to close wounds on soft tissues and to hold shell fractures in place.
• Retractors and hemostats: Help maintain the operating field clear and help to control bleeding.

3. Large-Scale Instruments for Shark and Large Aquatic Animal Care

Sharks and other large ocean animals, such as stingrays, require heavy-duty surgical instruments that can withstand their strength and size. Some of the most frequently used instruments are:

• Heavy-Duty Surgical Scissors: For incising thick cartilage and skin.
• Liposuction cannulas: Sometimes used to drain cysts or remove excess tissue.
• Giant Hemostats and Clamps: Needed to stop bleeding during extensive surgeries.

Common Surgical Operations in Exotic Fish and Aquatic Animals

As much as surgical operations on aquatic animals are not as common as those on land mammals, there are times they are needed for the correction of injuries, infection, or congenital defects. Some of the most common among them are:

1. Koi Fish Tumor Removal

Koi fish, which live for decades, sometimes develop tumors that must be surgically removed. The surgeons use microsurgical instruments to carefully remove the tumor, doing as little damage as possible to the delicate tissues of the fish. These procedures are often performed under sedation, when the fish are placed in a wet operating bed.

2. Shell Repair in Turtles

Turtles frequently develop shell fractures due to car accidents, predation, or improper handling. The fractures are stabilized and the shell cleaned meticulously with the application of bone plates, wires, or medical-grade epoxy. In other cases, external fixation devices are used, which require precise placement with orthopedic instruments.

3. Cyst and Abscess Drainage in Sharks

Sharks occasionally develop cysts or abscesses, and these can be drained through trocars or liposuction cannulas. Since sharks need to keep moving in order to breathe, surgeries are often performed in shallow water tanks with circulating systems so that the animal has adequate oxygenation.

4. Eye Surgery in Aquarium Fish

Exotic aquarium fish such as betta and angelfish sometimes have eye infections or trauma that require microsurgery. In some cases, traumatized eyes are completely removed with micro scalpels and fine forceps.

Advancements in Aquatic Animal Medicine

As veterinary medicine continues to evolve, there are new techniques and technology that are raising the rate of surgery success for aquatic animals. Some of the most significant advancements include:

1. 3D-Printed Turtle Prosthetics

3D printing is applied in the manufacture of tailored shell prosthetics for injured turtles. The prosthetics give the animals mobility and protection, as well as greatly improving survival rates.

2. Laser Surgery for Sensitive Procedures

Laser technology provides bloodless cuts with minimal bleeding, ideal for delicate operations like tumor excision from fish. It also saves recovery time and minimizes the risks of infection.

3. Modern Anesthesia and Monitoring Systems

Very advanced water-based anesthetic systems provide better control of the level of sedation, lowering stress and making surgery successful. Very advanced monitoring systems also monitor heart rate and oxygen saturation levels during surgery.

4. Endoscopic and Laparoscopic Surgery

Minimally invasive technology like laparoscopy and endoscopy is being developed in aquatic animals to diagnose and treat disease with little trauma.

5. Regenerative Medicine and Stem Cell Therapy

Regenerative medicine is an emerging and new branch of aquatic veterinary medicine. Stem cell therapy is being explored by researchers to induce tissue repair in damaged fish and turtles.

Conclusion: The Future of Exotic Fish and Aquatic Animal Care

Greater understanding in the realm of aquatic animal medicine enables more effective provision of proper surgical care. Advances in surgical procedures, anesthesia, and treatment methods continually advance the limits of what is possible, enabling more veterinarians to save more animals and enhance the overall quality of life for exotic fish, turtles, and sharks.

For businesses that specialize in the production of surgical instruments, there is an increasing potential to create precision instruments specifically for aquatic animal care. Whether creating ultra-fine microscissors for fish surgery or rugged bone saws for turtle shell repair, innovation in instrument design will be a major factor in the future of this specialized industry.

Through ongoing development of surgical procedures and our knowledge of aquatic animal physiology, veterinarians are able to provide improved treatment alternatives, allowing these incredible animals to receive the treatment they require to survive.
