Title: Morphology of underyearling fishes in the zone affected by warm waters discharged from the Konakovo Power Station into Ivan'kovskoye reservoir

Abstract

An examination was made of the meristic and morphological characters of underyearlings of the main commercial species, namely roach (Rutilus rutilus), bream (Abramis brama), perch (Perca fluviatilis) and pike (Esox lucius) from the zone affected by waters discharged from Konakovo power station into Ivan'kovskoye reservoir. These characters were compared with the morphological characteristics of underyearlings from a control bay. The results showed that there were no significant differences between the meristic characters of the species studied. This is connected with the earlier spawning time of the fish, as a result of which embryogeny and development of the young occurred at temperatures similar to those in the control and around the optimum for each species. The morphological characters of roach and bream underyearlings from the warm water zone and the control area did differ. There wre differences in the size of the paired and unpaired fins and in the ventroanal distance. In addition, greatest and least body depth were increased in roach underyearlings of the warm water zone, while the depth of the head at the occiput, the length of the caudal peduncle and the base length of the anal fin were increased in the bream. There were no significant differencesmore » in perch and pike underyearlings. (FMM)« less
