Why Can Alliin/Allicin Repel Parasites?
Alliin/allicin can effectively repel parasites in fish, primarily due to its potent natural bioactive properties. It contains powerful sulfur-containing compounds that significantly disrupt and damage the nervous systems and metabolic enzymes of parasites (such as certain protozoa and helminths), thereby paralyzing or even killing them. Furthermore, the distinctive pungent odor...
Should the Water Pump, Air Pump, and UV Sterilizer Be Turned Off During Medication?
For safety and efficacy, the water pump and air pump should remain ON, while the UV sterilizer must be turned OFF. Keep Water & Air Pumps Running: Oxygen Supply: Continuous aeration is crucial as most medications increase the fish's metabolic stress and oxygen demand. Turning off pumps risks hypoxia. Even...
Should Feeding Be Stopped During Medication?
Yes, it is generally recommended to stop feeding during most medicinal treatments. Professional and effective medications are often irritating and can induce stress in koi. It is advisable to withhold food one day before administering the medication. Feeding should be suspended throughout the treatment period, and normal feeding can resume...
Under What Circumstances Should the Standard Dosage Be Adjusted?
The standard dosage should be appropriately increased when the water temperature is below 15°C, as most medications become significantly less effective below 13°C. Conversely, when medicating Tosai(yearling koi), the standard dosage should be appropriately reduced due to their lower tolerance. Naturally, the dosage may also need to be increased if...
Is It Necessary to Conduct Continuous Parasite and Bacteria Treatment for Koi Transferred from Earthen Ponds?
Yes, koi transferred from earthen ponds typically carry the parasites and bacteria present in their original environment. After being moved to a recirculating tank or pond, it is essential to conduct at least two rounds of strict parasite and bacteria treatment before they can be introduced to other fish in...
Should Koi Be Frequently Caught for Examination?
The process of being caught and netted causes significant stress for koi, triggering a stress response that can severely impact their growth and even lead to illness. Therefore, it is crucial to minimize such handling unless absolutely necessary. The key is to develop the ability to diagnose common issues without...
Can Salt Be Used Long-Term in Koi Keeping?
No, it is not advisable to maintain koi in salted water continuously. Prolonged exposure to salt can disrupt the fish's natural osmoregulatory functions, impair the luster and thickness of the Hi(red pigmentation), and may even lead to fading of the red patterns. When using salt for treatment—especially at higher concentrations—the...
Why Maintaining a 0.3% Salinity Can Mitigate Nitrite Poisoning?
Maintaining a 0.3% salinity primarily alleviates nitrite poisoning by utilizing chloride ions (Cl⁻) from salt to "block absorption channels" on fish gills, preventing toxin invasion. Nitrite (NO₂⁻) enters the bloodstream through gill cell membranes, binding to hemoglobin and reducing its oxygen-carrying capacity, which can suffocate koi. By adding sufficient salt,...
Why Must Nitrite Testing Be Conducted in the Absence of Light?
Nitrite testing requires strict protection from light, primarily for the following scientific reasons: Reagent Photosensitivity Key components in the test reagents (e.g., diazotization reagents such as N-(1-naphthyl) ethylenediamine) are photolabile. Exposure to light, especially ultraviolet (UV) rays, can cause photodecomposition, breaking down the chromogenic molecules and severely reducing color development...
Common Dosages of Salt in Koi Care and Treatment
The use of salt (typically non-iodized coarse salt or aquaculture-grade salt) is a fundamental and important supportive measure in koi conditioning and treatment. It primarily works by regulating osmotic pressure to reduce the fish's physiological burden, inhibit certain pathogens, and promote mucus secretion. Here are the three common concentration levels...
Is it necessary to disinfect and sterilize the pond for koi carp in spring and autumn?
Yes, it is highly advisable to carry out appropriate preventive disinfection of the pond during spring and autumn. These two seasons are critical periods when imbalances among water temperature, fish immunity, and pathogen activity are most likely to occur: Risks in Early Spring: Water temperatures begin to rise but fluctuate...
Possible Causes of Body Curvature in Koi Carp
Body curvature (also known as spinal deformity) in koi can result from various factors, with differing chances of recovery depending on the severity and underlying cause. Common reasons generally fall into the following three categories: 1. Environmental Factors & Physical Trauma If there is an electrical leakage in the pond,...
