In this study, we report the complete mitochondrial DNA (mtDNA) sequences of the allotetraploid and triploid crucian carp and compare the complete mtDNA sequences between the triploid crucian carp and its female parent Japanese crucian carp and between the triploid crucian carp and its male parent allotetraploid. Our results indicate that the complete mtDNA nucleotide identity (98%) between the...

The aim of this study was to investigate the genetic mechanism of the transparent trait in transparent crucian carp. We observed body color development in transparent crucian carp larvae and analyzed heredity of color in hybrids produced with red crucian carp, ornamental carp, and red purse carp. The results showed that the body color of the newly hatched larvae matured into the adult pattern a...

Silver crucian carp (Carassius auratus gibelio) is a unique triploid bisexual species that can reproduce by gynogenesis. As all other gynogenetic animals, it keeps its chromosome integrity by inhibiting the ®rst meiosis division (no extrusion of the ®rst pole body). To understand the molecular events governing this reproduction mode, suppression subtractive hybridization was used to identify th...

The aim of this study was to determine the selectivity of monofilament gillnets with different mesh size for silver crucian carp in Eğirdir Lake. In this study, it was investigated that the selectivity of monofilament gillnets with nominal mesh size (stretched) with 32, 40, 50, 60, 70, 80, 90 mm and trammel nets with 100, 110, 120, 130, 140, 150 mm for catching of silver crucian carp. Fieldwork...

Fishes show a remarkable diversity of shapes which have been associated with their swimming abilities and anti-predator adaptations. The crucian carp (Carassius carassius) provides an extreme example of phenotypic plasticity in body shape which makes it a unique model organism for evaluating the relationship between body form and function in fishes. In crucian carp, a deep body is induced by th...

The crucian carp (Carassius carassius L.) exhibits the unique ability among vertebrates to maintain cardiac performance at normoxic levels during prolonged anoxia exposure. This thesis investigates the hypothesis that this phenomenon is possible because the heart likely never experiences an extracellular pH below 7.4 due to the fish’s exclusive trait of converting lactate and H ions to ethanol....

In many species of aquaculture importance, all-female and sterile populations possess superior productivity due to faster growth and a relatively homogenous size of individuals. However, the production of all-female and sterile fish in a large scale for aquaculture is a challenge in practice, because treatments necessary for gynogenesis induction usually cause massive embryonic and larval morta...

The silver crucian carp (Carassius auratus gibelio), a gynogenetic teleost, is a promising model for the study of evolutionary genetics in vertebrates. We identified ten gynogenetic clones (FZ-I~FZ-X) from triploid silver crucian carp, collected from Fangzheng County in Heilongjiang Province, China, using microsatellite markers. The genetic diversity of these gynogenetic clones was analyzed usi...
