Different back archesBody fat: developed head must match the stout body, otherwise the terms. Systemic vision onHeart location should be in fish central location of wrinkles. His spine can be divided into straight back, half-camponotus tonkinus and three. Camponotus straight back or whatever,Back and smooth, with no necessary nilin, lift and residual fins, nail. Mouth wide eyes wide, commonly known as "big" brain mechanisms. As the head of leave enoughGrowth space.
Egg kind of meatballs developed head of walks freely: tiger-head goldfish swim attitude should be explicit and lively freely, excessive channeling hop and too slow and undesirable. Tail handle stout, tail finThe four yeping exhibition, fin-soft and flexible. Still, the fish, not be biased towards the side of the forward planting head of individuals should beIs eliminated.
The most popular red top tiger-headColorful: flake, rich in reflective smooth and polished, natural color distribution, not cluttered. Five flower varieties, blue bottom RedThe head, five color combination is. Blocks of thick, the edges of optimization. Red top, jade top, red head of variety, color distributionOut of bounds, without noise. According to the breeders of many years of experience, discolored, late of the individual colors more sustainable.
Wang Word before and after the discoloration tiger-head, from an ugly duckling variable at the procedure
Wang Word tiger-head discolored longer, to second age to complete
Wang Word tiger-head of rejuvenation of: Wang Word tiger-head is one of Beijing's traditional goldfish varieties, because this growth cycle length, to the second instarAbove its characteristics is as other varieties of Goldfish head tiger-head of development and discolored. In the Decade, big fishField to keep, only a small number of breeding hand closed. Several generations of kin breeding results, although get purification, commoditiesZoogeography is maintained. But inbred offspring, manifested by the vitality of the recession, the decline in yield and quality, regress. ABody prematurely appear bags back bow collapse of adverse consequences. Make them lose their ornamental value.
Soochow University aquaculture graduate Wei bin have on different groups of tiger-head genetic diversity for comparative research, applicationMorphological and molecular genetics and Immunology on tiger-head goldfish three geographical groups are compared between the germplasm conservation and breeding geneticsWork has provided some guidance. He with the help of microsatellite DNA Molecular markers, and other molecular genetics methods on its group to study genetic relationship, Hangzhou, Suzhou, Nantong, and tiger population genetic background a difference, it is recommended that you divide Suzhou tiger-head goldfish and Nantong groups crossing, with a view to get a high genetic diversity, strong hybrid art.
Apply the same theory, find other line (or similar) from source hybrid is Wang Word tiger-head of deteriorationOne way. Wuxi goldfish masters Mr Hui Kei source teacher suggested: to the rejuvenation of Beijing character tiger-head, you can use the Beijing producing characterTiger-head and Tianjin or Suzhou, tiger-head goldfish hybrid, with their descendants and the return of the King's words Tiger, combined with individual choice and progenyGrowth situation, you can also make hybrid or back again, so that after three to four generations of breeding, to achieve the objective of rejuvenation. Although this needTo a process, but have a credible experience in guiding and scientific research, are worth a try.
