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.

No ,they can’t

@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.

No they can’t, because of the high salinity but they can survive in brackish water

[Felicitas Obisie]

No they can’t

Freshwater shrimps of the genus Neocaridina which are kept in captivity (aquarium) have “dirty” gills (visible through the transparent carapace). The “parasite” was not motile. Mortality was recorded. Is it a parasite, bacterial infection or what is it?Freshwater shrimps of the genus Neocaridina which are kept in captivity (aquarium) have “dirty” gills (visible through the transparent carapace).

There are commercial Calcium/phosphorus supplements you can give in water for 3days.

Light stimulation begins at week 20 of age…. whereas double yolks in laying hen are a function of genetics or breed specific and the use of feed additives ( Egg booster).

Hi everyone,

What are your experience insights about using Rye in poultry feed and as sell rumination?

Thanks!
