Nadrmvs components are classified pt charoen pokphand in terms of salmon, rainbow trout Byshtrgvnh

Farmed fish are generally divided into two groups: warm water fish and cold water will be released as part of the first group. Lymph trout Lav. Though the climate is more temperate zones, however, nearly every one of the provinces of or more area for cold water fish breeding there.
The best temperature for trout growth of around 17 C, but if the temperature is constant throughout the year, producing reproductive elements, pt charoen pokphand and thus are not subject to reproduction in fish. Some aqueducts and fountains of water, may be such a property, the trout waters are suitable for fish propagation, but it must be done in waters with temperatures eight to 10 degrees centigrade.
Caspian salmon trout is actually a great character just because it is said to salmon, trout, farmed fish usually like dieing after spawning. These fish are totally edible part of the fish Lzyztryn Most of the prices are high, which is important for farmed trout.
They are constructed to foster specific workshops Although it can be relatively cool waters of the stream, fountains, aqueducts, and is limited to producing developed for family use. At present, pt charoen pokphand the annual production rate of 10,000 tonnes of the fish is undoubtedly still in the future will increase.
Breeding or fish culture in artificial multi-millennial history but salmon farming is a relatively new activity. The beginning of the last century Bmnzvrtamyn fish and increase fish stocks in the water for fishing were raised artificially, there are theories that suggest that fish reared at the first West Indian American began transferring eggs from rivers to farms . Leading Danish fish were rainbow trout for human nutrition, the industry is already pervasive in most developed countries is cold. Reared Atlantic salmon in Scotland and Norway and more recently in Chile and Tasmania has been rapid progress, salmon native to the Pacific West Coast and Canada, in addition to training in those areas as well as in countries such as New Zealand develops.
Nadrmvs components are classified pt charoen pokphand in terms of salmon, rainbow trout Byshtrgvnh of farmed salmon or Salmvnydh is the first species of family farming in the provinces of Mazandaran and va-is important.
Salmon eggs are very sensitive to temperature and hitting. With elastic and Asprmatvyyd hole is called the micropyle in the eggs into it. Taking eggs from the female and male fish's sperm called Tkhmgyry so, it will feed the fish first and then anesthetized by anesthetic ms222 Tkhmgyry take action. The eggs and sperm together and slowly poured to alter fertilization occurs within 30 to 120 minutes.
The male fish for 4 to 5 fish material is used, depending on the location and temperature of the spawning changes Kndbdyn That is what the water temperature is lower during spawning pt charoen pokphand backward falls and vice versa in both the quality of eggs decreases. This time can be Tkhmgyry selective use of artificial or pre-cast pituitary injection. Factors such as rapid Alrshdbvdn, color, maturity Dyrs to prevent seed quality and resistance to diseases that are involved in the selection of broodstock. Temperature, sex, nutrition, light Zadmahyan involved in the investigation, in addition to these shortening pt charoen pokphand days, Hzvrjns Mkhalfv pt charoen pokphand flow of water in the fish may help premature, mature female fish can be identified by their protruding abdomen.
Vent Mtvm and red fish for signs of readiness are stripped, Nrrsydh fish hook is also lower jaw. Males and females in two years in the second and third years to reach sexual maturity. pt charoen pokphand Trout eggs in the abdomen with Bsyarhsas does not have the ability to tolerate violence and therefore the classification of varieties and Tkhmgyry each no more than 2 to 3 fish harvested by hand tour of the fish because it Prkrd the reproductive system of damage to the breaking Tkhmhav.
The age and size of fish eggs feed depends on the selection of those fish that produce eggs camels should be selected. 1553 eggs per month, on average, two years and three years, 2210 to produce eggs that weigh approximately 30 per 305 pcs. Agrqbl of maturity of the fish eggs Tkhmgyry not acting strongly reduced fertilization rate and the number of time division and proliferation of smooth overripe eggs are not to be clear that the relationship sanies secreted from the ovary Matte The eggs are called bat.
The method is done to fertilize dry dry due to the possibility of increasing the micropyle opening Stunt Tkhmgyry a few fish in a bowl is a better. Gyrdk h Tkhmgyry operations are carried out in different ways just mentioned are:
Finally, after removing dead eggs, healthy eggs to become larvae into special baskets or incubators are transferring. Long and 50 cm in width baskets usual standard 25/36 cm, 15 cm, hollow tube that is placed in a small frame and can be hung inside the channel.
Depending on how well incubated eggs, three types of water and contact with the drip tray and box shape are divided. Slide the tray incubators and placed vertically on the eggs to become larvae are kept absorbing the yolk sac. Check-in type
