Hello Everyone, I hope you are in good health.
Can anyone please tell me how we can access our attended courses which we attend virtually through our USSEC portal?? I have not find any option of courses which I attend previous ones. I need to re attend them for missing information. Regards.

You should be present feed during low temperature hours 🌡️such as early day and night .save water requirements all time avoid feed at higher temperature hours

Feeding is important. Please how we can manage feeding in the Summer during hot weather. Bird feed intake is very less due to hot weather?

thank you for sharing.

Catfish are generally freshwater fish and are not well-suited for saltwater environments. While some species of catfish can tolerate slightly brackish water (a mixture of fresh and saltwater), most catfish cannot survive in a saltwater habitation.
Catfish have some physical limitations that make it difficult for them to thrive in saltwater, which are:
1. Osmoregulation: Catfish are not able to regulate their body’s salt and water balance in saltwater, which can lead to dehydration and other physiological problems.
2. Gills: Catfish have gills that are designed for extracting oxygen from freshwater, not saltwater. Saltwater can cause their gills to become irritated and functioning poorly.
3. Scales: Catfish have scales that are not designed to withstand the corrosive effects of saltwater, which can lead to damage and infection.
Although, there are a few species of catfish that can survive in saltwater for short periods or in areas where the water is brackish (partly salty). For example:
– The Hardhead Catfish (Ariopsis felis) is a species of catfish that can tolerate some amount of saltwater and is often found in brackish waters.
– The Gaff-topsail Catfish (Bagre marinus) is another species that can survive in saltwater.
It’s important to note that even if a catfish can tolerate or survive in saltwater, it may not thrive or grow well in such environments.

@Aquaculture Fresh water catfish catfish are strictly freshwater fish and cannot contain high salinity level in sea and oceans as exposure to saltwater can lead to osmoregulatory stress, resulting in health problems and potentially death.
While most catfish are restricted to freshwater, some euryhaline species can survive and thrive in brackish and saltwater environments.
