Water quality with ph meters and catfish farming.

Nothing stresses the fish quicker than poor quality water. The maintenance of water quality is critical to the success of your fish farm. 

.

.

Water quality management is the Key to success of everything, we do in fish farming. 

.

.

Fish will lose their appetite in poor quality water and usually show signs of stress as the conditions deteriorate. 

.

.

The situation under investigation could be an early warning sign of an impending critical water quality problem. PH and levels may be low or high, thus depriving the fish of a key ingredient for fast growth and Development.

💥Water that has a pH that is too low or too high can be harmful to fish and other aquatic life. .

.

.

💥At low pH, toxic metals such as aluminum can enter the water in greater concentrations, some nitrogen-bearing chemicals become more toxic, and the metabolic processes of fish can become less efficient. .

.

.

💥Water with pH below 5 can inhibit reproduction or lead to death, and young fish and other aquatic organisms are especially susceptible. Water with a pH below 6.0 can inhibit growth.

💥At high pH values (such as >9), most ammonium ions are convert

Importance of Water Quality in Aquaculture

Fish perform all their bodily functions in water. Because fish are totally dependent upon water to breathe, feed and grow, excrete wastes, maintain a salt balance, and reproduce, understanding the physical and chemical qualities of water is critical to successful aquaculture. To a great extent water determines the success or failure of an aquaculture operation.

Very high (greater than 7.5) or very low (less than 6.5) pH values are unsuitable for most aquatic organisms. Young fish and immature stages of aquatic insects are extremely sensitive to pH levels below 5 and may die at these low pH values.

High pH levels (9-14) can harm fish by denaturing cellular membranes. Changes in pH can also affect aquatic life indirectly by altering other aspects of water chemistry. Low pH levels accelerate the release of metals from rocks or sediments in the stream. These metals can affect a fish's metabolism and the fish's ability to take water in.

High pH Levels Effect

At high pH (>9) most ammonium in water is converted to toxic ammonia (NH3) which can kill fish. Moreover, cyanobacterial toxins can also significantly influence fish populations.

NOTE: One critical parameter is pH: Not only for the health of the fish, but for the bacteria have that cleaned up the water as well as nitrifiers that remove excess nutrients.

pH is important in aquaculture as a measure of the acidity of the water or soil. Fish cannot survive in waters below pH 6.5 and above pH 7.5 for long periods. The optimum pH for fish is between 6.5 and 7.5. Fish will grow poorly and reproduction will be affected at consistently higher or lower pH levels

TDS= Total Dissolved Solids;

The ability of water to dissolve, combine with, or suspend other elements and compounds can be helpful as a supply of necessary nutrients. Water can also be a source of trouble for the fish farmerd because it can contain chemicals that are irritants or toxic to fishes. Aside from overall stress, water quality is the most common cause of fish diseases. 

A constant level of minerals in the water is necessary for aquatic life. Changes in the amounts of dissolved solids can be harmful because the density of total dissolved solids determines the flow of water in and out of an organism’s cells. Concentrations that are too high or too low may limit the growth and may lead to the death of many fish.

A level of 400ppm or less is recommended for most freshwater fish although many softwater fish demand a significantly lower level. 

Total Dissolved Solids are also important for proper osmotic regulation, which is the relationship of water versus dissolved solids in the cells and the external environment.

The greater the amount of solids in the water versus the solids in the tissue of the fish will result in a fluid loss via the gills. 

 EC = means electrical conductivity. This is a measure for measuring the sodium concentration of a solution.

Electrical conductivity in a substance occurs when it contains sodium. For example, when you add nutrients (consisting of sodium) to water during the production of a fertiliser tank, a certain amount of electrical conductivity is created in the water.

The more sodium you add, the higher the EC will be. The EC also increases at a higher temperature.

With the help of an EC-meter you can measure this. When you treat with salt bath you could use EC to measure the necessary amount of salt to apply so u wont injure your fish.

You can use it to tell if ur water is rich enough for fish, planktons and other prokaryotes, etc to trive.

Since total dissolved solids content of a softened water is the same as that of the untreated raw water, a supply with a lower dissolved solids content must be gained in some other way. Blending of softened water with reverse osmosis or distilled water may produce the conditions conducive to aquatic breeding. 

It is critical to regulate the alkalinity & buffering capacity (pH) of the water as well

Salinity
Salinity is the dissolved salt content of water and is often ex-pressed as the parts of salt by weight per thousand parts of water by weight (ppt).

Channel catfish can breed and reproduce over a wide range of salinities.

Eggs can hatch and fry will de-
velop in waters with salinities up to at least 8 parts per thousand, but the optimum salinity for channel catfish hatchery supplies appears to be between 0.5 and 3 ppt
(500 to 3,000 ppm).


TDS to beneficial Hardness testing.

Hardness refers to the amounts of calcium and magnesium in the water and is expressed as ppm of equivalent CaCO3.

Adequate concentrations of environmental calcium are required for “hardening” of eggs and for normal bone and
tissue development of fry.

Symptoms of environmental calcium deficiency include swelling and poor Hatchability of eggs and slow development, lack of vigor, poor stress resistance, and low survival
of sac fry.

A minimum of 5 ppm calcium

hardness is required for adequate egg hatchiability and for development and vigor of sac fry. Higher calcium concentrations are desirable because calcium also protects fry from ammonia and metal Toxicosis.

All things considered, hatch-
Every water supplies should contain at least 20 ppm calcium hardness.
Calcium levels can be increased by adding a solution of calcium chloride to the water supply.

The calcium solution can be added by chemical metering pumps or by using an inexpensive
