Several methods exist for the breeding or propagation of cultivated fish. Choosing among them depends on the reproduction biology of the species, on local environmental conditions and on the facilities available. These methods may be grouped into three categories: natural propagation; semi-natural propagation; artificial propagation. 2 artificial propagation. After providing an identification key to P. djambal, practical aspects related to fish transportation, broodstock management, induced spawning, artificial fertilization, egg incubation, larval rearing and fish health management are developed in this manual
. Progeny from the Snake River Sockeye Salmon captive broodstock were reintroduced into Redfish were a product of an artificial propagation strategy (eyed egg box, presmolt, or smolt) as determined by using mark, scale, and trap information (brood year 2004 and 2005) and genetic assignments (brood years. Since the 1990s, artificial propagation and breeding technique of marine fish in China have developed by way of increasing species and fry numbers, with special stress laid on valuable species. Large quantities of artificial fry can meet the needs of both marine cage culture and pond culture for most species. Experimental results obtained by scientists have been put into use in actual.
Steps in artificial propagation 1. capture of wild brood fish from spawning grounds, 2. selection of breeders from wild stock for natural spawning or for hormone treatment, 3. rearing of brood fishes, 6. 4 Artificial Propagation through Hypophysation The hypophysation technique which uses the pituitary gland (the hypophysis) to induce spawning in fish can be carried out at any time of the year and under any environmental conditions. The technique ensures fish seed availability at all times of the year 3. Grafting. We will now describe all these methods, one by one. Let us start with the cuttings method for the artificial propagation of plants. 1. Cuttings : A small part of a plant which is removed by making a cut with a sharp knife is called a 'cutting'. A cutting may be a piece of stem, root or even a leaf als on artificial propagation, including hor- mone-induced spawning of captive brood- stock, culture of larvae through metamorpho- sis, and growout of juveniles in a recirculat- ing culture system, are described.

Consequently, a fish farmer skilled in the artificial propagation of common carp will have no problem in adopting this technology to the propagation of other valuable carps of the region such as other Cyprinids (Horváth et al., 2015, Targońska et al., 2010, Targońska et al., 2011, Targońska et al., 2012, etc.). Reproductive biology. Catfishes are the group of fish species belonging to the family claridae inhibiting marine, estuaries and freshwater habitats. The most common method of administering the hormone solution, is by intra-muscular injection into the dorsal muscles. Artificial propagation of catfish video. Posted by Luth Japhet at 1:06 PM
Abstract. Induced spawning of the African catfish (Clarias gariepinus) was successfully carried out using natural hormone (homoplastic hormone-pituitary extract from Clarias gariepinus).The study which was carried out at Bahir Dar Fisheries and Other Aquatic Life Research Centre lasted 78 days (June to October) fish propagation, fish cultivation, fish conservation. 3 major phases of fish culture. fish propagation. it is the natural or artificial method of promoting reproduction and survival of fish. natural method. man does not interfere in the reproduction cycle the organism. artificial method Artificial vegetative propagation is the deliberate production of new plants from parts of old plants by humans. This can be done by following three methods: 1. Cutting 2. Layering 3. Grafting. Cutting The part of the plant which is removed by cutting it from the parent plant is called a 'cutting' Besides natural methods of vegetative propagation, artificial modes of propagation are also being used. Farmers, gardeners and horticulturists have adopted several such methods like grafting, layering, cutting and tissue culture for propagating plants in gardens and nurseries. 1

The process of growing many plants from one plant by man-made methods is called artificial propagation of plants. The types f three artificial methods of propagation is: Layering: In this method, the young branch is bent and pressed into moist soil Grafting is an artificial method of asexual reproduction used to produce plants combining favorable stem characteristics with favorable root characteristics. The stem of the plant to be grafted is known as the scion, and the root is called the stock. Grafting has long been used to produce novel varieties of roses, citrus species, and other plants According to an example, artificial ovulation and spawning of freshwater eels may be induced to promote artificial ovulation without employing intraperitoneal injection, by feeding a.. Methods of artificial vegetative propagation - Cutting (by stem cutting) - definition. The common method of artificial vegetative propagation are cutting, grafting, budding and layering. Cutting. Cutting is removing a portion of the stem and fixing it in the soil to allow the growth of roots and buds growing into shoots

Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem. This can occur through fragmentation and regeneration of specific vegetative parts of plants. Artificial method of vegetative propagation: Artificial method of vegetative propagation is carried out by humans in the fields and laboratories Artificial Method of Vegetative Propagation . In addition to the natural methods of vegetative propagation as described above, several artificial methods of vegetative propagation are practised. Following are the important artificial methods of vegetative propagation. Cuttings . The portion of any plant organ such as stem, root or leaf, used.
The invention relates to the technical field of culture of special species, and discloses a method for raising and propagation of teleogryllus emmas. The teleogryllus emmas are raised by adjusting conditions of temperature and photoperiod, and the method comprises the following steps: (1) under the condition that the temperature is 25-30 DEG C, raising an imago in a first raising box; (2. Examples are: Tip Layering. Simple Layering. Compound Layering. Division. A method where the plant is broken down into two or more parts, with the roots and the crown is kept intact. Budding or Grafting. Another common method of propagation where a plant bud is grafted onto the stem of a rootstock plant Fish Commission were twofold. The Commission had been established by Congress in 1871 to make scientific investigations of marine life and to study and gather statistics about the methods of the fishery industry. Now the Fish Culturists Association proposed to expand those objectives by adding artificial propagation to the Commis-sion's work
The invention relates to an artificial propagation method of yellow catfish fry, which is characterized in that: sexually mature yellow catfish over three years are chosen as the parent fishes the female and male ratio is 3:1 a plurality of barrels are arranged in a spawning pond as fish nests parent fish density in the spawning pond is 1 to 2 groups/m2 each group of parent fishes uses a. This discovery was made by a Russian fish culturist in 1856 and is very important to the artificial propagation of fish as it enables the crossing of different species. The eggs when first spent in the water have the shape of a slightly pressed in rubber ball, and as soon as they come in contact with liquid, they expand and suck it in through a. This method allows propagation of rare, endangered species that may be difficult to grow under natural conditions, are economically important, or are in demand as disease-free plants. To start plant tissue culture, a part of the plant such as a stem, leaf, embryo, anther, or seed can be used which was quite successful. In 1857 Dr. Garlick published a treatise on the artificial propagation of fish, which first appeared in a series of numbers of the . Ohio. Farmer, and was afterward gathered into a volume. To these gentlemen should be ascribed the merit of inaugurating interest in fish culture in this country

In most cases, the fish culturist adopts that technology which he finds easiest to apply and which provides successful results. However, the degree of success may not be the same with different methods. The details of various activities involved in artificial propagation are given in the succeeding s. propagation, artificial propagation through hypophysation. Process of artificial propagation through hypophysation techniques includes the use pituitary gland to induce spawning in fish; this can be carried out at any time of the year and under any environmental conditions
Gardeners and farmers use artificial methods of vegetative propagation to increase the Stock of a plant. The following two are the most common methods of artificial vegetative propagation.1 Artificial Aquarium Propagation. Aquarium plants can also be propagated artificially by means of cuttings, and by dividing rhizomes and rootstocks. Cuttings All plants with a central stem supporting a number of leaves can be propagated by cuttings. Most stem plants sold either as bunches or potted up are simply top cuttings from established plants This simple and cost effective method of propagation could be used to produce individuals throughout the year. This shows the potential use of this method to fulfill the high demand of sea anemone in sea water aquarium trade or to restock depleted coral habitats, thus supporting biodiversity conservation in coral reef areas Artificial Propagation of Plants is a method in which new plants are grown by placing them in a suitable environment. It consists of three methods i.e. cuttings, layering and grafting Artificial Neural Network architecture used in this study for freshness classification and fish variety identification of the images . Back propagation algorithm will be used for training the ANN to achieve the desired output. The trained output will then be generated into C codes by MATLAB Coder implemented for android use.

Based on the temperature drift characteristic of fiber optic gyroscope (FOG), a novel modeling and compensation method which integrated the artificial fish swarm algorithm (AFSA) and back-propagation (BP) neural network is proposed to improve the output accuracy of FOG and the precision of inertial navigation system. In this paper, AFSA is used to optimize the weights and threshold of BP. METHODS OF ARTIFICIAL VEGETATIVE PROPAGATION: The artificial method of vegetative propagation includes cuttings, layering, grafting and micropropagation. Cuttings: Stem cuttings are generally used to obtain new plants. At times, roots are not easily produced in the cuttings and hence, they are treated with growth hormones (IAA, IBA, NAA). Plants like sugarcane, Bougainvillea, rose, china rose. Artificial reproduction is the creation of new life by other than the natural means available to an organism.Examples include artificial insemination, in vitro fertilization, cloning and embryonic splitting, or cleavage.. Cutting plants' stems and placing them in compost is also a form of artificial reproduction.. References. www.cmf.org; See also. Male Pregnanc Artificial Method. Shad eggs differ essentially from trout eggs and require wholly different manipulation. They are much smaller and lighter. If a trout or salmon egg is dropped into water it sinks at once to the bottom, but a shad egg will almost float, and has but little more specific gravity that the water itself. Shad eggs are less than half the size of trout eggs and require as their best.

Cuttings, A small part of a plant which is removed by making a cut with a sharp knife is called a 'cutting'. A cutting may be a piece of stem, root or even a leaf. While making a cut, care should be taken to see that there are some buds on it
Asexual Propagation. Asexual propagation of plants can also be called 'vegetative propagation' because it involves the use of vegetative parts of plants like leaves, stems, roots, or modified organs. It's the best method to use to clone your plants, which means to produce plants identical to their parents . This process creates a new plant which is called a clone because it is genetically. This method of artificial vegetative propagation is widely used in plant like Litchi citrus pomegranate and guava. Natural methods of vegetative propagation Among seed plants vegetative propagation by natural method is very common vegetative organ such as root stems and leaves bears adventitious bud and bring about the formation of new plant
Advantages of vegetative propagation-1) It is easier, quicker, and less expensive method of propagation. 2) Characters of the parent plant are preserved. A superior variety can be produced by vegetative means. 3) It is the only method of reproduction in plants which do not reproduce viable seeds such as seedless grapes, rose, banana e.t.c . The stem of the plant to be grafted is known as the scion, and the root is called the stock Methods of Vegetative Reproduction: (i) Natural methods and (ii) Artificial methods. 1. Natural Methods: In such methods of vegetative propagation, a portion of the plant gets detached from the mother plant and develops into a new independent plant under suitable environmental conditions.

There is a number of methods of the artificial propagation of plants that are used in the agriculture (for raising crops), and the horticulture (the cultivation of the vegetables, the fruits, and the flowers), The three common methods for the artificial vegetative propagation of plants are cuttings, grafting, and the tissue culture The method is employed for obtaining pathogen free clones (e.g. Potato, Strawberry, Carnation, Garlic) or multiply those plants which show slow vegetative propagation, e.g. Orchids, Pineapple. The apical meristem with one or two young leaves is cut from the shoot tip and culture medium which helps in the development of roots Artificial neural network is determined by 3 aspects: the network architecture, method for determining the connection weights, and the activation function. Some research has been tested with back-propagation methods, such as fingerprint recognition, face recognition, et cetera. (Nugroho, 2011) 2.3. ANN back-propagation architectur Aquaculture means the propagation, culture and maintenance of fish for the purpose of selling such fish or a product derived from such fish in the regular course of business, or the culture of fish pursuant to a class 1 or class 2 license, but not including the scientific or educational propagation, culture and maintenance of fish, or the sale.
Answer: Explain artificial methods of vegetative propagation in plants. Cutting - In this, a portion of a plant is cut and planted in the soil, usually a stem or a leaf. Grafting - In this, the cutting from some other plant is added to the plant stem embedded in the soil. Layering - In this, the stem of the plant is bent to the. Intensive polyculture and monoculture of fish is very expensive and risky. In this system the probability of diseases is most. This farming system get obstructed due to lack of better facilitated artificial farm. It is not possible to make the fish big sized in this system. Intensive polyculture and monoculture needs highly experienced employee Apart from the above mentioned natural methods of vegetative reproduction, a number of methods are used in agriculture and horticulture to propagate plants from their parts. Such methods are said to be artificial propagation. Some of the artificial propagation methods have been used by man for a long time and are called conventional methods . The overall impact of hatchery fish can be divided into three broad categories. First, over-harvest of wild stocks in mixed stock fisheries can have a profound impact on survival of wild stocks. When abundant hatchery stocks are tar geted for high harvest, less abundant wil
Controlled propagation--Among animals, it includes natural or artificial matings, fertilization of sex cells, transfer of embryos, development of offspring, and grow-out of individuals of a species when the species is intentionally confined or the mating is directly intended by human intervention These commenters argued that artificial propagation and hatchery-origin fish are more appropriately considered in the context of taking into account those efforts, if any, being made by any State or foreign nation, or any political subdivision of a State or foreign nation, to protect such species, whether by predator control, protection of. This study will evaluate and review several different methods of coral reef restoration including asexual propagation and sexual propagation both with in situ and ex situ nurseries, as well as physical restoration and artificial reefs. It will also look at a range of existing organisations in South-East Asia carrying out coral reef restoration Artificial vegetative propagation in plants. Vegetative propagation is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structure from the stem, root or leaf. Few important methods of artificial vegetative propagation in plants are as follows
PLANT PROPAGATION. Propagation is the process of creating new plants. If you have ever planted a seed or stuck a stem in water until it forms roots that you stuck it in a pot or planted it in the garden, you have experienced propagation. Some plants are easier than others to propagate and different methods work better with different plants Abstract Wild-caught mutton snapper Lutjanus analis, a high-value marine food fish species, matured in flow-through seawater (36 g/L) tanks after 3 yr in captivity. On 31 May 1995, a female with a mean oocyte diameter of 382 μm was injected wit Plant propagation using artificial or synthetic seeds devel oped from somatic and not zygotic embryos opens up new vistas in agriculture. Artificial seeds make a promising technique for propagation of transgenic plants, non-seed producing plants, polyploids with elite traits and plant lines with problems in seed propagation. Being clonal in.
Methods include mid-water coral nurseries or mineral accretion devices such as Biorock ™ technology. Mid-water nurseries are used as a staging area for rehabilitation of damaged or propagated corals before they are placed back out onto artificial or natural substrates Artificial Propagation . Section 3(3) of the ESA lists artificial propagation as a method that may be used for the conservation of listed species. Hatcheries have been used in recovery efforts of other listed fish species (Rinne et al. 1986). The draft bull trout recovery plan (USFWS 2002) recognized tha technology method of propagation could be used to produce individuals throughout the year and the anemones could then be used to supply the aquarium trade or restock depleted habitats, thus supporting biodiversity conservation in coral reef areas.
