Good, thanks for the information

Excellent, thanks

Agree with “By increasing fish farms, the amount of nutrients discharged to natural sources will increase, which has a negative effect on the environmental balance”.

How different organic acids affect gut micro flora of the poultry?

Aquaculture has several environmental concerns that impact ecosystems and communities. Some of the key issues include:
– *Water Pollution*: Aquaculture can lead to water pollution through nutrient overload, excess feed, and waste accumulation, causing eutrophication, algal blooms, and oxygen depletion.
– *Habitat Destruction*: Aquaculture farms often require large areas of land and water, leading to habitat destruction, loss of biodiversity, and increased coastal vulnerability. Mangrove forests and wetlands are particularly vulnerable ecosystems.
– *Disease and Parasite Spread*: Intensive aquaculture practices can facilitate the spread of diseases and parasites among farmed and wild fish populations, posing risks to ecosystem health.
– *Genetic Disruption*: Escaped farmed fish can interbreed with wild populations, altering genetic makeup and potentially weakening wild fish populations.
– *Chemical Use and Antibiotic Resistance*: Aquaculture often involves the use of antibiotics and other chemicals, contributing to antibiotic resistance, pollution, and harm to non-target species.
– *Greenhouse Gas Emissions*: Aquaculture contributes to greenhouse gas emissions through energy consumption, feed production, and waste management.
– *Resource Overuse*: Aquaculture relies heavily on wild-caught fish for feed, contributing to overfishing and pressure on marine ecosystems.
– *Water Usage and Waste Management*: Aquaculture requires significant water resources, and poor waste management can lead to water pollution and waste accumulation.
To mitigate these concerns, sustainable aquaculture practices focus on:
– *Recirculating Aquaculture Systems (RAS)*: Closed-loop systems that minimize water usage and prevent pollution.
– *Integrated Multi-Trophic Aquaculture (IMTA)*: Combining species like fish, shellfish, and seaweed to mimic natural ecosystems and reduce waste.
– *Best Management Practices (BMPs)*: Implementing BMPs, such as optimizing feed management and biosecurity measures, to reduce environmental impact.
– *Sustainable Feed Sources*: Exploring alternative feed sources, like plant-based proteins and algae-based alternatives, to reduce reliance on wild-caught fish.
– *Regulatory Frameworks*: Strengthening regulations and monitoring systems to ensure aquaculture operations prioritize environmental sustainability.Aquaculture has several environmental concerns that impact ecosystems and communities. Some of the key issues include:

Acidification of soils :If a farm is land based and has to be abandoned for any reason this can leave the soils eroded and too salty to be used for other forms of farming in the future.
pollution of drinking water : Inland aquaculture has been linked to the pollution of water bodies used for human drinking water. One such study estimated that one farm producing 3 tonnes of freshwater fish would generate the equivalent waste of 240 people.
introduction of invasive species :There have been a total of 25 million reported fish escapes worldwide, usually as a result of damaged netting, which occurs in severe storms or hurricanes.

Escaped fish have the potential to affect wild fish populations by outcompeting them for food and other resources. This not only directly affects wild fish populations but also forces local fisherman in the area affected to fish in other areas which might already be overexploited.
Aquaculture can have some positive impacts for the environment, especially when carried out in a sustainable and well-regulated fashion.
Reduces pressure on wildlife : Overfishing is a big environmental problem, driven by a growing global desire for fish. According to the Food and Agriculture Organization (FAO) over 70% of the worlds wild fish species are either fully exploited or depleted. This disrupts ecosystems, taking away predators or prey species from the oceans.
Other problems from industrial scale sea fishing include:
- bycatch where large nets are cast catching unwanted species which are simply discarded;
- injuring and deaths of wildlife caught in discarded fishing nets and lines (sometimes known as ghost fishing);
- trawling of nets along the sea bed causing damage and stirring up sediments.

There is no single “expected shrinkage percentage” for corn stored under these conditions because the total loss is dynamic and depends on multiple factors. The high temperatures (35–49°C) and high humidity (60–70%) are not safe storage conditions for corn and will lead to rapid deterioration and quality loss, making any calculation of a stable shrinkage percentage impossible. The overall loss will be a combination of moisture shrink and significant dry matter loss from mold and respiration

myth:
white eggs are less beneficial than the brown eggs.
-
excellent effort to highlight the significance of egg. Egg is the good and cheaper source of protein, vitamins, minerals etc.
