To describe the occurrence of various spinal deformations in a captive-bred wild line of Poecilia wingei (P. wingei).
Fish belonging to a wild line of P. wingei caught from Laguna de Los Patos, Venezuela, were bred in an aquarium home-breeding system during a period of three years (2006-2009). The spinal curvature was observed to study spinal deformities in P. wingei.
Out of a total of 600 fish, 22 showed different types of deformities (scoliosis, lordosis, kyphosis), with a higher incidence in females. Growth, swimming and breeding of deformed fish were generally normal.
Possible causes for spinal curvature in fish are discussed on the basis of the current literature. While it is not possible to determine the exact cause(s) of spinal deformities observed in the present study, traumatic injuries, nutritional imbalances, genetic defects or a combination of these factors can be supposed to be involved in the pathogenesis of such lesions.
描述人工养殖的野生翼斑花鳉(Poecilia wingei,简称P. wingei)品系中各种脊柱畸形的发生情况。
从委内瑞拉洛斯帕托斯湖捕获的野生翼斑花鳉品系的鱼,在水族箱家庭繁殖系统中饲养了三年(2006 - 2009年)。观察脊柱弯曲情况以研究翼斑花鳉的脊柱畸形。
在总共600条鱼中,22条出现了不同类型的畸形(脊柱侧凸、脊柱前凸、脊柱后凸),雌性的发生率更高。畸形鱼的生长、游泳和繁殖通常正常。
根据当前文献讨论了鱼类脊柱弯曲的可能原因。虽然无法确定本研究中观察到的脊柱畸形的确切原因,但可以推测创伤性损伤、营养失衡、遗传缺陷或这些因素的组合参与了此类病变的发病机制。
