Tilapia Lake Virus (TiLV)

  Tilapia Lake Virus (TiLV) is a serious threat to the global tilapia aquaculture industry. Here's some additional information about TiLV: - Symptoms and Signs Tilapia fish infected with TiLV can exhibit symptoms such as exophthalmos and corneal opacity, pale gills, skin lesions especially around the mouth and fins, abnormal behavior such as erratic swimming, lethargy, or disorientation, loss of appetite, abdominal swelling due to fluid accumulation, pale liver tissue, and tissue inflammation. - Transmission and Risk Factors TiLV can be transmitted through direct contact between fish, contaminated water, and global trade of tilapia fry. Risk factors include environmental changes that can weaken the fish's immune system, such as changes in water temperature, high fish density, poor water quality, and stress on the fish. - Prevention and Treatment There is currently no effective treatment for TiLV. However, some prevention strategies can be implemented, such as applying strict ...

Global Aquaculture

 Aquaculture plays a crucial role in global food security by providing an efficient and sustainable source of protein. With the world's population projected to reach 9.7 billion by 2050, the demand for sustainable food sources is increasing. Aquaculture has developed rapidly as an alternative to meet the world's protein needs, with more than 50% of global fish consumption now coming from aquaculture. Aquaculture offers several benefits, including high-quality protein sources rich in omega-3 fatty acids, vitamins, and minerals. Additionally, aquaculture has higher production efficiency compared to land-based livestock farming, as some fish species have low feed conversion ratios, reducing the need for resources. Aquaculture can also reduce environmental impacts compared to wild-caught fisheries, which are at risk of overexploitation and degradation of marine ecosystems. The diversification of food sources provided by aquaculture is not limited to fish, but also includes other pr...

Aquaculture in the World

 Aquaculture has experienced significant growth globally over the past few decades, with production values consistently increasing. This sector has become a major contributor to global food production, particularly in meeting the protein needs of the population. Global trends indicate that the freshwater sector dominates global aquaculture production, accounting for 52.25% of total production in 2015. This suggests that freshwater aquaculture has great potential in meeting global food needs. The freshwater sector includes the cultivation of freshwater fish such as catfish, carp, and tilapia. In terms of major producing countries, China dominates the global market with a total production value of USD 183,281 million, accounting for approximately 58.6% of global production. China has an advantage in aquaculture technology and adequate infrastructure to support this industry. India ranks second with a production value of USD 17,232 million, focusing on the freshwater sector. Vietnam r...

Tilapia Aquaculture

 Raising tilapia fish at home offers various significant benefits, both economically and environmentally, as well as for health. Here is a more detailed explanation of these benefits: Raising tilapia fish can be a promising source of additional income. By selling the fish, individuals can improve their family's economic welfare and that of the surrounding community. This not only impacts income increase but also opens up new business opportunities in the fisheries industry. In addition to being a source of income, tilapia fish is also a healthy food source rich in protein and nutrients. The high protein content, omega-3, vitamin D, and other minerals in tilapia fish make it a good choice for improving nutritional intake in the community. Regular consumption of tilapia fish can help maintain body health and improve quality of life. Raising tilapia fish at home can also be a fun and engaging hobby. This activity not only provides an opportunity to care for and maintain fish but also ...

Managing diseases in Nile tilapia

 Managing diseases in Nile tilapia requires a comprehensive and integrated approach to ensure the success of tilapia farming. Here are some strategies that can be implemented to manage diseases in Nile tilapia: Prevention is a proactive step that is highly effective in managing diseases in Nile tilapia. Maintaining optimal water quality can reduce the risk of disease in Nile tilapia. This can be achieved through regular monitoring of water parameters, including pH, temperature, and ammonia concentration. Additionally, reducing stress on fish by providing a comfortable environment and reducing stocking density can also increase the fish's resistance to disease. The use of balanced and nutritious feed also plays an important role in enhancing the immune system of Nile tilapia. Accurate diagnosis is crucial in the management of diseases in Nile tilapia. Visual examination of clinical symptoms, such as changes in behavior, skin color changes, or lesions on the fish's body, can prov...

Diseases Affecting Nile Tilapia

 Nile tilapia is one of the most widely cultivated freshwater fish species. However, like other fish, Nile tilapia is also susceptible to various diseases that can cause significant economic losses. Diseases Affecting Nile Tilapia Bacterial Diseases - Aeromonas hydrophila: causes skin lesions, swelling, and mortality. This bacterium can infect Nile tilapia at various life stages. - Pseudomonas fluorescens: causes skin and gill lesions. Infection can lead to stress and increased mortality risk. - Edwardsiella tarda: causes skin and internal organ lesions. This bacterium can cause mass mortality in Nile tilapia if not promptly treated. Parasitic Diseases - Ichthyophthirius multifiliis (Ich): causes white spots on the skin and gills. This parasite can lead to stress and increased mortality risk. - Trichodina sp.: causes fish to rub against the pond surface. This parasite can damage the skin and gills. - Dactylogyrus sp.: causes gill damage. This parasite can lead to stress and increas...

BIOFLOC

Biofloc fish farming is a method of fish cultivation that uses biofloc technology to increase productivity and resource efficiency. Here are some benefits of biofloc fish farming for food security: - Increased Productivity: Biofloc can increase fish productivity by more than 3 times compared to conventional methods. With higher stocking density, biofloc can produce more fish in a shorter time. - Land Use Efficiency: Biofloc can be done in smaller ponds and does not require large land areas, making it suitable for areas with limited land. - Efficient Water Use: Biofloc can reduce water usage because the system can process organic waste into natural feed for fish. - Improved Water Quality: Biofloc can improve water quality by balancing carbon and nitrogen, and reducing fish feed costs. - Environmentally Friendly: Biofloc is an environmentally friendly technology because it can reduce waste and process it into natural feed for fish. An example of successful biofloc fish farming can be see...
