野生和养殖硬骨鱼的骨骼、鳍和鳞片都有形态畸形的记录。在自然条件下，野生畸形鱼的患病率通常很低。然而，在水产养殖中，由于亲鱼的遗传问题，关于最佳环境饲养条件的知识空白，（包括营养）和由于没有捕食和其他自然选择压力而人为提高的存活率（Tave，Bartels & Smitherman 1983; Koumoundouros，Divanach & Mouri 2001; Sfakianakis et al. 2003; Koumoundouros 2008;维滕& Huysseune 2009; Georgakopoulou et al. 2010; Tong et al. 2012）。在野生鱼和养殖鱼中观察到的一种特殊类型的骨骼畸形是鞍背综合征（SBS），其特征是背鳍的一个或多个硬刺的畸形或缺失，伴随着支撑背鳍的形状、数量和位置的异常（Tave等人，1983; Koumoundouros等人，2001）。SBS可影响一系列硬骨鱼类（Tave et al. 1983; Browder et al. 1993; Setiadi et al. 2006; Koumoundouros 2008; Al-Mamry et al. 2010），但鲷科成员似乎特别易感
Morphological deformities of the skeleton, fins and scales have been recorded from both wild and cultured teleosts. Under natural conditions, the prevalence of deformed fish in the wild is usually very low. However, in aquaculture, the prevalence of deformities can be elevated due to genetic issues with broodstock, gaps in knowledge regarding optimal environmental rearing conditions (including nutrition) and artificially elevated survival rates due to the absence of predation and other natural selective pressures on deformed larval or juvenile fish (Tave, Bartels & Smitherman 1983; Koumoundouros, Divanach & Kentouri 2001; Sfakianakis et al. 2003; Koumoundouros 2008; Witten & Huysseune 2009; Georgakopoulou et al. 2010; Tong et al. 2012). One particular type of skeletal deformity that has been observed in both wild and cultured fish is saddleback syndrome (SBS), which is characterized by deformity or loss of one or more of the hard spines of the dorsal fin, accompanied by abnormality of the shape, number and position of the supporting pterygiophores (Tave et al. 1983; Koumoundouros et al. 2001). SBS can affect a range of teleosts (Tave et al. 1983; Browder et al. 1993; Setiadi et al. 2006; Koumoundouros 2008; Al-Mamry et al. 2010), although members of the family Sparidae appear to be particularly susceptible
