What is Hypophysation technique?
Hypophysation is a method used in the breeding of fishes. The technique of hypophysation employs the injection of the pituitary gland extract that induces breeding in fish. The technique also includes the induction of various gonadotrophin hormones in the body needed for breeding purposes.
How do I increase fish in my pond?
Manuring: After 15 days of liming, manuring or fertilization is done in order to facilitate the growth of fish food organisms. Manure can be of organic or chemical nature. The application rate of raw cow dung for stocking pond is 2-3 tonnes/ha. The application rate of poultry manure is 5000 kg/ha.
How do you control water turbidity in a shrimp pond?
Gypsum. Gypsum must be applied in large amounts to remove turbidity. The usual treatment rate is 100-150 mg/L, but tests may be made in jars to ascertain the lowest effective treatment rate. In a 1-ha, 1-m-deep pond, 100 mg/L would require a dose of 1,000 kg/ha.
How do I add oxygen to my pond?
A very simple way to add oxygen to the pond is to add an air pump. Sitting at the side of the pond, it will pump air through a small hose to an air stone and bubbles will enter the water. When the bubbles break the water’s surface oxygen will then be added.
What is exotic carps?
Exotic carps are those species that are non-indigenous having their origin in another country and has been introduced into the Indian waters. They generally have established culture technologies and the economics of production and marketability.
What is Ovatide?
Ovatide, an injectable inducing hormone consisting of GnRH analogue in combination with dopamine antagonist, is also efficient in induced spawning (Gupta et al 2002 and Sahoo et al 2004). The aim of the present study was to test the effectiveness of different doses of Ovatide in induced spawning of Clarias batrachus.
Which pair of fishes is exotic?
Some of the exotic fishes found in India are 1. Carassius carassius 2. Ctenopharyngodon idella 3. Cyprinus carpio 4.
Which one is an exotic fish?
Invasive and Exotic Fish
| Subject Name | Scientific Name | Order |
|---|---|---|
| walking catfish | Clarias batrachus | Siluriformes |
| yellowbelly cichlid | Cichlasoma salvini | Perciformes |
| Asian snakeheads | Channa spp. | Perciformes |
| bighead carp | Hypophthalmichthys nobilis | Cypriniformes |
How do you use Ovatide?
Hold the fish firmly and inject the calculated amount of Ovatide solution intramuscularly in the region of caudal peduncle above the lateral line using a 2 ml hypodermic syringe having 0.1 ml graduations fitted with a No. 22 needle.
What is the main composition of Ovaprim?
DESCRIPTION: Ovaprim® is a liquid peptide preparation that contains an analog of salmon gonadotropin releasing hormone (sGnRHa) and a brain neurotransmitter (dopamine) inhibitor. The sGnRHa in Ovaprim® elicits the release of stored gonadotropins from the pituitary.
Which is the modern drug used in fish breeding?
Ovatide is an indigenous, cost-effective and new hormonal formulation for induced breeding of fishes. It is also effective in breeding major carps.
What is the best fertilizer for fish ponds?
Generally phosphorus is the limiting primary nutrient most often missing in natural water supplies for good growth of planktonic algae. Therefore, phosphate fertilizers are usually the most effective inorganic fertilizers for fish ponds in most regions of the world.
What chemicals are used in fish farming?
Chemicals used in aquaculture included sodium chloride, formalin, potassium permanganate, copper compounds, malachite green and methylene blue (Li et al., 1996).
Which is the modern drug used in fish breeding Ovaprim?
The sGnRHa in Ovaprim® elicits the release of stored gonadotropins from the pituitary. The dopamine inhibitor (Domperidone) serves to remove other inhibition of GnRH release. Release of stored pituitary gonadotropins may aid spawning by stimulating ovulation and spermiation in sexually mature fish.
When is a scale used to weigh an object submerged in water?
When a scale is used to weigh an object submerged in water the scale will read the apparent weight. When performing ( ). . For an object to be in static equilibrium, all of the forces on it must be balanced so that there is no .
What happens when acid is added to water?
In the beginning, the acid added will be neutralized by compounds in the water, such as bicarbonates. As more acid is added, the bicarbonates get “used up”, as it is also being neutralized by the acid. Eventually all the acid-neutralizing compounds are used up.
What makes a water molecule a cohesive molecule?
Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.
How does an injection system raise the pH of water?
Injection systems are a point-of-entry system. A corrosion-resistant chemical feed pump injects soda ash or sodium hydroxide solution into the water to raise the pH. The solution should be fed directly into the well to protect the well casing and pump from corrosion.
When a scale is used to weigh an object submerged in water the scale will read the apparent weight. When performing ( ). . For an object to be in static equilibrium, all of the forces on it must be balanced so that there is no .
What happens to body weight when submerged in water?
A given of low tissue will take up relative to the same mass of high density tissue. Taking up the volume means more water is when the body is submerged so the will be larger compared to the than it would be for a more dense body. In turn, that means that apparent weight is smaller relative to actual weight for bodies of higher density.
Why does water make up 60 percent of your body weight?
The Mayo Clinic states, “Water is your body’s principal chemical component, making up, on average, 60 percent of your body weight. Every system in your body depends on water. For example, water flushes toxins out of vital organs, carries nutrients to your cells and provides a moist environment for ear, nose and throat tissues.
Which is the best definition of water purification?
Water purification, process by which undesired chemical compounds, organic and inorganic materials, and biological contaminants are removed from water. Water purification provides clean drinking water and supplies treated water for domestic, industrial, medical, and pharmacological uses.
