1. Fish may suffer from injuries due to accidental collisions, and overstocking in the pond leads to high density, making them more susceptible to brucellosis. Affected fish show gray-white, soft cotton-like growths on their bodies that are visible to the naked eye. The fish become weak, swim abnormally, lose appetite, and eventually die. Prevention methods include: 1) treating the pond with a mixture of 0.04% salt and 0.04% sodium bicarbonate; 2) applying 4% iodine solution directly to injured areas of broodstock; 3) soaking fish eggs in 4% formalin for 2–3 minutes.
2. River crabs are prone to water mold disease, often caused by poor water quality, low water exchange, or physical damage from predators or mechanical injury. The main symptom is the presence of gray, cotton-like fungal hyphae on the crab's body. To prevent this, drain the pond to a depth of 30 cm, replace with fresh water, and apply 20 kg of calcined lime per 667 square meters. Additionally, treat the water with 0.0005‰ "strong chlorine" or 0.02‰ of a suitable antifungal agent.
3. Shrimp are commonly affected by fungal infections, especially juvenile shrimp. Infected shrimp develop white, opaque spots at the base of the tail and appendages, which spread rapidly and lead to mass mortality. To control the infection, soak shrimp daily in a 0.02% formalin solution for 30 minutes.
4. Mites can infest the skin, limbs, and neck of turtles. In severe cases, they cover the entire body, causing serious harm to young turtles and even leading to death. Affected turtles may become restless, refuse to eat, and gradually weaken. To prevent mite infestation, treat the water with 0.002‰ to 0.003‰ methylene blue every two days, repeating the treatment twice.
5. Overstocking and inadequate feeding in the astragalus (a type of fish) can lead to injuries from biting or rubbing, creating wounds that are then infected by mold. To prevent this, dip sick fish in a 2% saltwater bath. Additionally, feed them 500–800 units of crude chrysanthemum bait daily at a concentration of 3%, continuing for 3–4 days if necessary.
6. Accidental handling or bites from other fish can cause injuries to the leather beard fish, leading to mold infections. To prevent this, treat the water with 0.001‰ "strong chlorine." Alternatively, dip infected fish in a 2%–4% saltwater solution for 10–15 minutes.
By implementing these preventive measures, aquaculture farmers can significantly reduce the risk of disease outbreaks, ensuring healthier aquatic life and better yields. Regular monitoring of water quality, proper stocking densities, and timely treatment of injuries are key to maintaining a thriving and disease-free environment for all aquatic species.
IV Infusion:
Intravenous simply means "within vein" (or "inside the vein"). Therapies administered intravenously are often included in the designation of specialty drugs. Intravenous infusions are commonly referred to as drips because many systems of administration employ a drip chamber, which prevents air from entering the blood stream (air embolism), and allows an estimation of flow rate.
Intravenous therapy may be used to correct electrolyte imbalances, to deliver medications, for blood transfusion or as fluid replacement to correct, for example, dehydration. Intravenous therapy can also be used for chemotherapy.
Compared with other routes of administration, the intravenous route is the fastest way to deliver fluids and medications throughout the body. The bioavailability of the medication is 100% in IV therapy.
Intravenous infusions are fluid solutions administered through a vein. There are numerous different types of solutions available, but they can be broken down into simple categories depending on the function they serve. Some replace lost fluids, and others provide nutrients, replace lost blood, and deliver medications.
One of the most common uses for intravenous infusions is to replenish fluids lost through dehydration. These infusions often contain normal saline solution, a combination of sterile water and sodium chloride. This solution is known as an isotonic crystalloid, or a solution that contains the same amount of electrolytes as plasma in the body. It is used in cases of moderate to severe dehydration, such as that caused by vomiting or diarrhea, when replacing the fluids quickly is vital.
When a patient`s gastrointestinal tract is compromised and nutrients cannot be absorbed - or eating can worsen the condition - intravenous infusions called total parenteral nutrition may be given. These solutions contain a mix of sterile water, electrolytes, sugar, proteins, fats, and other nutrients, depending on the needs of the patient. Diseases and disorders that commonly require total parenteral nutrition include late stages of Crohn`s disease, obstructive bowel disorder, and ulcerative colitis.
Intravenous infusions are also used to deliver medication directly to the blood stream. Certain medications, such as intravenous immunoglobulin, a type of antibody, can only be given through the vein. Other medications, such as certain narcotic pain relievers, are given intravenously because the method allows them to they work faster than when taken orally. Chemotherapy for treatment of cancer is also typically given intravenously.
When performed by a medical professional, intravenous infusions are typically safe. The most common reaction is mild pain and redness at the site of the injection, although different medications may cause different side effects. Any time the skin is punctured, there is a risk of infection. Having a medical professional, typically a nurse, monitor the intravenous infusion and change the injection site when irritation is evident can help prevent complications.
