“…There are reports demonstrate that temperature, salinity, pH and oxygen may cause developmental anomalies (Westernhagen, 1988;Gercken et al, 2006;Arbuatti et al, 2011). However, we did not observe significantly different or anomalous conditions of environmental variables at critical stations (St-9, 10 and 13).…”

“…their bodies (Arbuatti et al, 2011). Twining usually occurs due to the presence of two developmental centers arisen from one germ ring, which is known as polyembryony and has been classified according to conjoining body parts and developmental level (Laale, 1984).…”

“…The presence of a stressor during development may be related to the increasing rate of embryonic malformation regardless of the malformation type (Westernhagen, 1988). Numerous studies have shown temperature and salinity out of the species specific optimal range (Westernhagen, 1988), thermal shocks (Owusu-Frimpong and Hargreaves, 2000), hypoxic conditions (Gercken et al, 2006), extreme pH (Arbuatti et al, 2011), chemical compounds such as triphenyltin (Zhang et al, 2008), heavy metals (Jezierska et al, 2009) and aromatic, chlorinated and petroleum hydrocarbons (Westernhagen, 1988) may cause polyembriyony in fish eggs.…”

Conjoined twinning is a rarely existed gross malformation in natural conditions. The term refers to the two individuals united at any part of their bodies. The extraordinary incidences of conjoined twinning cases may reflect important problems on the marine environment. Therefore, the purposes of this study were to report the incidences of Trachurus mediterraneus conjoined twins in Bandırma Bay, Southern Marmara Sea and to discuss the possible causes of them to derive new research questions. Four polyembryonic individuals were collected from three stations of Bandırma Bay Ichthyoplankton Survey in June 2012. The anomalous individuals were observed at the stations, St-9, 10 and 13 (Critical Stations). St-9 was at about 20m depth contour between Karşıyaka town and Dalyan village in western coasts of bay. St-10 and 13 was off Yenice village at about 10 and 30m depth contours respectively in the eastern coasts of the bay. The surface temperature, salinity, dissolved oxygen and pH of critical stations were seemed to be normal. Therefore the pollution was considered as the most possible reason of these incidences.

There is growing use of hybrid catfish (Ictalurus punctatus ♀ X Ictalurus furcatus ♂) in commercial aquaculture to utilize hybrid vigour to improve production A conjoined twin specimen found during the course of production studies by the United States Department of Agriculture Catfish Genetic Research Unit (USDA-CGRU) was submitted to the Aquatic Research and Diagnostic Laboratory (ARDL). After preliminary inspection, it was transported to Mississippi State University, College of Veterinary Medicine for further evaluation. The specimen was examined using both computed radiography and computed tomography antemortem. Following humane euthanasia, the specimen was examined both grossly and histologically. Tissues from both fish were also submitted for genetic analysis to determine whether twins were derived from the same egg. This report records the presentation and examination of a pair of conjoined hybrid catfish (I. punctatus X Ictalurus furcatus).
