Liyang City in Jiangsu Province has seen significant improvements in its aquaculture industry, particularly in high-yield fish ponds. The key to maintaining excellent water quality lies in ensuring sufficient dissolved oxygen levels and effective feeding and management practices. One of the most critical measures is the regular use of fresh irrigation water, complemented by the strategic use of aerators.
The irrigation method is carefully adjusted according to seasonal changes in temperature and pressure. From mid-May, pond water depth is maintained at 1–1.2 meters. During June and July, the depth is increased to around 2 meters, with water temperatures ranging between 15–20°C. At this stage, fresh water is introduced every 5 days. When the temperature rises to 20–25°C, irrigation occurs twice a week for 3–5 hours. When the temperature reaches 25–30°C, fresh water is added once every 2 days for 4–6 hours. This approach keeps the pond water clean, clear, and highly transparent, promoting strong photosynthesis and maintaining optimal dissolved oxygen levels above 5 mg/L for extended periods. The pH level is consistently kept between 6.5 and 7.0, creating an ideal environment for all types of fish to grow, thrive, and remain healthy.
This system also helps prevent the presence of harmful pests such as small melon worms and Chinese sturgeon, which can negatively impact fish health. By maintaining a balanced aquatic ecosystem, fish are more resistant to diseases, especially those caused by parasites like gill lice. This reduces the need for chemical treatments, improves growth rates, enhances fish size, and ensures that the final products meet high-quality standards for culture-free aquatic goods.
Aerators are used only when the water becomes too thin or when there is a lack of oxygen. When activated, they significantly improve oxygen levels and maintain a stable pH range, providing the best possible living conditions for the fish. They also enhance feed utilization, allowing fish to digest and absorb nutrients more efficiently after feeding.
In commercial ponds of 15–20 mu, two additional aerators and one 8-inch water pump are typically installed. When oxygen levels drop, these systems work together to ensure adequate oxygenation, preventing fish from suffocating. This not only protects the fish but also avoids economic losses due to oxygen deficiency. Overall, this integrated approach of water management and aeration leads to healthier fish, higher yields, and better-quality aquaculture products.
Antimalarial & Antiparasitic
Antimalarial:
Antimalarial
medications, also known as antimalarials, are designed to prevent or cure
malaria. Such drugs may be used for some or all of the following:
Treatment of
malaria in individuals with suspected or confirmed infection
Prevention of
infection in individuals visiting a malaria-endemic region who have no immunity
(Malaria prophylaxis)
Routine
intermittent treatment of certain groups in endemic regions (Intermittent
preventive therapy)
Some antimalarial
agents, particularly chloroquine and hydroxychloroquine, are also used in the
treatment of rheumatoid arthritis and lupus-associated arthritis.
Current practice
in treating cases of malaria is based on the concept of combination therapy,
since this offers several advantages, including reduced risk of treatment
failure, reduced risk of developing resistance, enhanced convenience, and
reduced side-effects. Prompt parasitological confirmation by microscopy, or
alternatively by rapid diagnostic tests, is recommended in all patients
suspected of malaria before treatment is started. Treatment solely on the basis
of clinical suspicion should only be considered when a parasitological
diagnosis is not accessible.
Antiparasitic:
Antiparasitics are
a class of medications which are indicated for the treatment of parasitic
diseases, such as those caused by helminths,amoeba, ectoparasites, parasitic
fungi, and protozoa, among others. Antiparasitics target the parasitic agents
of the infections by destroying them or inhibiting their growth;[4] they are
usually effective against a limited number of parasites within a particular
class. Antiparasitics are one of the antimicrobial drugs which include
antibiotics that target bacteria, and antifungals that target fungi. They may
be administered orally, intravenously or topically.
Broad-spectrum
antiparasitics, analogous to broad-spectrum antibiotics for bacteria, are
antiparasitic drugs with efficacy in treating a wide range of parasitic infections
caused by parasites from different classes.
