Analysis on Impact of Morphological Characters on Weight of the Naked Carp (Gymnocypris przewalskii) in Qinghai Lake
摘要
Abstract
The morphological characters are the foundation in the selective breeding of the naked carp (Gymnocypris przewalskii), one of the endangered species in China, in Qinghai Lake. The relationship between morphological traits and weight is primarily required. Therefore, a total amount of 200 2-year-old individuals were sampled for measuring nine metric traits, including total length,body length, head height, interorbital distance, body breadth, tail length, preanal distance and anal fin base length. The relationship between morphological characters and body weight was quantified through statistic methods, and the result indicated that all the morphometric traits were significantly correlated with body weight. According to multiple regression analysis, the body weight was significant influenced by body length, body height and anal fin base length (P<0.05). Path analysis indicated that body weight was intensively affected by body length, prior tohead height and anal fin base length.关键词
