The Environment Agency studied the spined loach in five catchments in England and confirmed for the first time that UK spined loach is the species Cobitis taenia. All the specimens examined in this report had a diploid chromosome number 2n=48 and other cytological features typical of Cobitis taenia. Other morphologically similar species and hybrids commonly encountered in central and middle Europe appeared to be absent from British populations.
