Changes in length-weight relationship and condition factor of Talang queenfish (Scomberoides commersonnianus) in the north-west Persian Gulf
Abstract Scomberoides commersonnianus is one of the commercially important fishes of the family Carangidae. In this study, 563 specimens (292 males, 247 females, and 24 sexually unknown ones) were collected from the north-west of the Persian Gulf. Length-weight relationships and condition factors were determined for each sex in four length classes within different seasons. In general, the growt...
متن کاملChanges in length-weight relationship and condition factor of Talang queenfish (Scomberoides commersonnianus) in the north-west Persian Gulf
The present study, which was conducted on Scomberoides commersonnianus as one of the commercially important fishes of Carangidae, seeks to investigate changes of length-weight relationships in different sexes, seasons and length classes and to calculate condition factor of Talang queenfish. In this study, 563 specimens (292 males, 247 females, and 24 of unknown sex) were collected from the nort...
متن کاملLength weight relationship, condition factor and length at first maturity of Indian halibut Psettodes erumei in the Persian Gulf
Length weight relationship, condition factor and length at first maturity of Indian halibut Psettodes erumei were investigated in the Persian Gulf by monthly sampling of 30 fish from March to February 2012. Mean value of total length and weight were 38.68 ± 9.39 cm and 986.92 ± 756.79 gr, respectively. Maximum and minimum values of total length were in August (44.43 ± 6.37 cm) and March (23.27 ...
متن کاملLength-weight and length-length relationships, Relative condition factor and Fulton?s condition factor of Five Cyprinid species in Anzali wetland, southwest of the Caspian Sea
This study was conducted to determine length-weight and length-length relationships, relative condition factor (Krel) and Fulton?s condition factor (K) for five species including Scardinius erythrophtalmus, Carassius auratus gibelio, Cyprinus carpio, Tinca tinca and Hemiculter leucisculus belonging to Cyprinidae family. Fish sampling was carried out by gill net and fyke net in the western regio...
متن کاملSwimming kinematics of juvenile kawakawa tuna (Euthynnus affinis) and chub mackerel (Scomber japonicus).
The swimming kinematics of two active pelagic fishes from the family Scombridae were compared to test the hypothesis that the kawakawa tuna (Euthynnus affinis) uses the thunniform mode of locomotion, in which the body is held more rigid and undergoes less lateral movement in comparison with the chub mackerel (Scomber japonicus), which uses the carangiform swimming mode. This study, the first qu...
