【Color】 stone silver carp artificial reproduction
Color stone silver carp is an adaptable, widely distributed wild small fish. As the body color bright and easy to raise, this fish has won many fish friends of all ages.

3, male and female points raised
And many people think different, I think colored stone is very aggressive males, and this attack from the larval stage of beginning to show. More than in April when the juvenile age, sex characteristics (ie, females start laying pipe extending from the mouth of the cloaca in vitro, and the male scales on his back began to appear metallic luster) beginning to show, the size difference between males and females began to become increasingly evident, The males frequently chase began near his other individuals, in the process of competition for food, females start at a general disadvantage, in order to ensure the future of the female reproductive body clearance, it is necessary at this time will be kept separate male and female. Points raised, I offer two rearing conditions are not much different. Color stone female character is more moderate, generally will not attack other individuals; and all male groups in the attacks will grow as more and more fish, which generally do not need human intervention, because it is natural to _select_ the individual the largest and most brilliant in color, the best male potential - that is always in a dominant state of those individuals - the process. However, in order to avoid unnecessary casualties and sick individuals have, a certain number of males compared with the same number of females need more space. In addition, I found that the smaller size of the wheat varieties of fish and other aquarium fish into the male can also reduce the intense chase between male behavior, because the former scattered those who are particularly aggressive individual attention.
▲ mussel
The existence of mussel reproduction Fang Welfare to basic conditions. I've seen a friend, speaking on mussel is not easy to feed, in fact I almost never raised clam died. I think the key to keeping mussel control of water temperature and water quality control. Mussel span, so basically impossible in the tropical fish tank, keeping them long; it would be best able to control the water temperature at 25 degrees Celsius. Ability to act as a bottom-dwelling animals is not very strong, mussel afraid of hypoxia, even the fish will be floating head in the water body is also raising bad mussel. In addition to filter feeding mussel general living algae and protozoa, so fertile mussel need that water, rather than keeping the old kind of Discus fish like clean water glass. To sum up, in fact, species of fish farming stones mussel tank will be able to keep well, and mussel in the tank in fact also played a role in water filter on the fish itself is beneficial. In order to provide a better clam living environment, changing the water too often. When I started to try to use the naked fish tank, each time changing the water is siphoning off waste products on the Bottom, for only about one-sixth of the whole tank can not. A friend said that in order to facilitate color stone eggs, you can stand in the sand in the mussels - in fact, even if the mussels are "flat lie" with the, stones can still go inside the eggs, because the female's ovipositor in the true ovulation may not usually see as soft, the egg laying tube into the tube will be in a whole similar to the "erection" of the state, straight thicker, can be easily _insert_ed into mouth of mussel gills. Of course, if covered with gravel or sand Bottom, then naturally no mussel into the sand, put a very convenient position using Fang Welfare (In fact, this treatment is to find something to eat its own position), no human hands The. Finally, I think for the mussel breeding the best stones and human hands about the same size, too small and too difficult to winter sports, too much keeping up too much room.
▲ mature broodstock management: group
Color Stone sexual maturity faster, generally to the hatching of the following year to be involved in reproduction. If sufficient natural light throughout the year where feeding, usually stones to the water temperature reaches 18 degrees Celsius day appeared lively reproductive behavior tendencies. Of course, where the climatic conditions in China are quite different stones began to breed so the period of the hydrological conditions and requirements may have significant regional differences. To determine whether to enter the reproductive state of male and female broodstock is very simple, characteristic based on the following:
Female: tube by a thin needle into a soft, tight and elegant translucent white ribbon, round belly bulge, a significant body color of white light (a lot of the female to sexual maturity and still remains a black spot on dorsal fin.)
Male: marriage was loaded, shiny scales, some swim rapidly overwhelming population of individuals with even the abdomen showed diffuse pink or dark red (the first year of losing male dorsal fin during the winter on spots simultaneously marriage installed), and the back of the blue-green contrast; regular earth, more rigid body like fat carp, chasing the attack was; if the cylinder has mussel, the long trip around the mussel action, and frequently the water hole in its inward peep.
When the broodstock after the above-mentioned traits, breeding group should be timely. Because the male has a strong color stone attack, so when there is more than a male cylinder when they attack each other quite frequently, which will lay eggs and the male and female of the pair have a very bad influence fertilization - color stone eggs into the mussel to the process compared to other fish, it takes a very long time and have a high movement difficulty, a small disturbance can affect female ovulation also make clam closed by stimulation tight shell, the mutual interference between males would greatly enhance the possibility of such a disturbance occurs. In addition, if males confronting each other in the long-term tension, the physical decline soon, will inevitably affect their reproductive capacity, even worse is the long-term intense male female and so there will be a very fierce attack behavior. In summary, the proposed period of breeding, one male and stones for the coordination of multi-female group, the proportion may vary due to the fish, it is proposed between 1:2 to 1:5. It is worth mentioning again, the female ovulation is periodic, the entire breeding period each female can ovulate several times, about 10 days each cycle, the change can ovipositor reflected in morphological changes; and male then has maintained a strong sex drive, so a mix of male and more females have different first, the female ovulation, you can ensure that most of the time have a female to lay eggs, thus improve the reproduction rate of the male species. |
