She is the Head of the Genetics Laborator Key words: Breeding, Clarias gariepinus, Larvae, growth performance Introduction Now a day's African catfish Clarias gariepinus is an important species in an aquaculture practicesamong Sudanese farmers. The preferably may refer to several advantage such as a wide feeding range, fast growth
breeding of Clarias gariepinus under varying brood stock ratios. Six gravid females weighing 1.00 kg each and 6 reproductively matured males weighing 1.00 kg were used for the three induced breeding trials in ratios of 2:1, 1:2 and 2:3, female/male respectively. Females were injected at a dosage of 0.50 ml ovaprim/kg body weight and 0.25 ml/kg bod Fish breeding in India is no longer a complicated technique. Several hormones are being used for induced breeding of fish on commercial scale using Chinese type hatchery mostly at the private sector. A new spawning agent, Ovopel was evaluated for spawning of Indian carps in Assam, India. The study conducted by Das (2004

The artificial reproduction of the African catfish, as for all fin-fishes, is a chain of activities which is more or less similar to that of natural reproduction. It starts with the selection of broodstock from nature or from the broodstock ponds after which they are transferred to the holding tank in the hatchery You will learn the basic psychology of catfish fries incubation, breeding and management of your own catfish hatchery operation leading to the production of hundreds of thousands of catfish fingerlings and juveniles in 4 to 9 weeks period after hatching
A study was conducted to observe the breeding and larval rearing of Asian Catfish, Clarias batrachus. fed with live and/or artificial feed for 21 days in an indoor hatchery. The brooders of . C. batrachus (Av. wt of female 160 ± 10.5 g; Av. wt of male 120 ± 6.75 g) were procured from outside ponds and stocked in a pond near the experiment sit age. Catfish have an elaborate breeding behavior and the male usually incubates the eggs. The period of incuba-tion (hatching time) of catfish eggs depends on water temperature. Eggs hatch in four to ten days at temperatures between 21 and 27°C (70-81°F); at optimum spawning and incubation temperatures (25°-27°C), embryos hatch in 4 to. The whole process of catfish breeding starts with identification of sexes and age of broodstock to be used. The average age for any breeding stock should be between 2-3 years to get healthy and good performing fingerlings. The male and female of the African catfish are similar in build yet different. The male has a distinct sexual papilla.

Some breeders, in order to gain profit faster and rush the process, usually hatch their fishes with fishes that are not mature enough, or sell the catfish juveniles with poor conditions. This can result in weak catfish and they will not thrive. For any successful catfish breeding and genetic improvement programme, there is the need for: Identification of the parent stock (i.e. external features of Heterobranchus and Clarias species); Sexing to identify male and female broodstock; Differentiation of hybrids from the putative parent stock. Heterobranchus and Clarias speices Catfish farming is an important agricultural industry in the United States, with more than 60,000 acres of water devoted to catfish pro duction. These catfish are being grown under several production systems and with various degrees of management. Successful catfish farming generally requires constructing facilities; controlling wate

With respect to African catfish (Clarias gariepinus Burchell 1822), the spe-cies of a well-grounded position in European fish culture (Huisman and Richter, 1987; Kuczyński et al., 1999), such experiments were carried out by numerous authors (among others by Eding et al. Moreover, genetics research and development of selective breeding programs for C. macrocephalus could provide the necessary means to improve growth rate and disease resistance of domesticated stocks, thus reviving farmers interests in producing C. macrocephalus—the species still preferred by consumers—instead of producing hybrid catfish According to the processors, the catfish industry would receive the most benefit from additional research in the following areas: (l) Improvement of the management and efficiency of catfish producers; (2) processing technology-- better skinning and dressing equipment; and (3) catfish breeding and genetics pennsylvania channel catfish spawning box standard drawing plan view pfbc 10/22/99 mbs 09 section view profile view materials and notes materials: rough cut hemlock lumber 1 x 9 x 8' - 2.5 pieces concrete patio block 16 x 16 x 2 - 2 pieces common nails (10d) -32 nails or 1/8 lbs 9 6 11 9 13 32 1

Fish Hatchery Management Dr. Abdel Rahman El Gamal ww.fishconsult.org. October, 201 African catfish is a carnivorous fish that displays cannibalistic behavior from the moment the African catfish have absorbed the yolk sac and start eating.

Catfish have been known to coexist with tilapia, koi, and crappie. Breeding It is ideal to have fine gravel at the bottom of your fish tank to achieve murky water if you plan to breed catfish. Some spots for hiding will also help as catfish like to hide when breeding Fish breeding includes commercially cultivating fish in ponds. In recent years, farmed fish for subsistence food has become common as more individuals strive to provide their families with safe supplies of farmed fish.

The walking catfish mate seasonally in the summer during the months between June and August. Heavy rains have a signaling effect on the catfish and are usually a prerequisite for mating. However, it has been found that the walking catfish, unlike other members of the Clariidae family have the ability to breed in stagnant water
Catfish farmers should use farmed females to farmed male broodstock of Clarias gariepinus for induced breeding to attain an effective and efficient fry production of catfish. This will ensure high seed production of C. gariepinus.

Effect of starvation on the characteristics of 24-h rhythm in surfacing activity of an Indian freshwater catfish, Clarias batrachus catfish spawn 2,000 to 3,000 eggs per pound of body weight; smaller females, about 4,000 eggs per pound of body weight (Figure 2). Place spawning containers in 2-3 feet of water, 1-10 yards apart, when the water is about 75°F. The containers can be wooden boxes, ammo cans, drums, etc. They must be large enough to accommodate the breeding pair The Breeding Stage Before you venture into catfish farming, you need to get a hold of the fingerlings and know the price. They can be obtained mainly through hormonal induction or artificial production, but if you prefer producing your own fertilized eggs, you may have to make use of the homoplastic gland suspension A fish hatchery is a place for artificial breeding, egg hatching, and rearing across the early life stages of aquatic animals (e.g. finfish and crustaceans). The output of a hatchery is normally fry, fingerlings or juveniles (with the respective name depending on the life stage/age of the fish). These young small fish are then transferred to an. Overview of the Common Suckermouth Catfish. While there are more than 150 species of armored catfish, one of the most prevalent in the aquarium trade is the original or Common Pleco (Hypostomus plecostomus). But unlike smaller species, such as the Bristlenose or Clown, Common Plecos often don't work out in community aquariums
A single female channel catfish can spawn 2,000 to 50,000 young. Each pond supports a limited number of catfish per acre, so channel catfish commonly becomes overpopulated without bass.

Female catfish ready to spawn or to produce offspring when it build its nest of debris or roots of aquatic plants like water hyacinths, kangkong, or filamentous algae. It spawns in shallow water, 30 cm to 60 cm deep. Male and female catfish starts courting by chasing each other, darting sideways, pressing their abdominal regions together Catfish Farming in Nigeria: Feasibility Study. The feasibility study included in this guide is for a farm capacity of 10,000 fingerlings and for a farm that is just starting. The Capital covers from pond construction (which is the common concrete type), fish feeding, production, to marketing. The farm has 10 ponds to contain 1,000 fingerlings.
