Pelvic
fin rays developed at 5.91 +- 0.34 mm (18 DPH, Fig.
Frequency distribution means and Kruskal-Wallis test results comparing latitudinal strata along southern and southeastern Brazil for the number gill rakers, second dorsal
fin rays and pectoral
fin rays of the whitemouth croaker Micropogonias furnieri.
Precision and relative accuracy of striped bass age estimates from otoliths, scales, and anal
fin rays and spines.
7L comes from the middle part of the anal fin where there are the longest
fin rays. Its medial longitudinal ridge is rather narrow with a broadening in the middle.
And although no femur bone was found, pelvic fin material, including long
fin rays, indicated the hind fin was at least as long and as complex as its forefin.
Principal component and/or discriminant functions revealed that meristic characters were highly correlated with pectoral
fin ray count, number of lateral line scales, as well as number of anal
fin rays.
The goal of this study was to evaluate the use of scales, pectoral
fin rays, and dorsal fin spines to estimate the age the largemouth bass.
Various structures have been used in osseochronometry of fishes, including scales, otoliths,
fin rays and spines, and opercular bones.
Many structures have been used to estimate the age of fishes, including scales, otoliths, vertebrae,
fin rays and spines, opercular bones, cleithra, urohyal bone, and hyomandibular bone.
The individual
fin rays are composed of longitudinally aligned segmented bones whose shape resembles that of a bamboo tree.
3M-P) from between the bases of the 2nd dorsal and anal
fin rays (the 1st dorsal fin was not studied) cover the ovoidal distal radials (Hilton et al.
clara specimens, nine meristic characters were recorded following methods of Williams (1975), including numbers of dorsal fin spines, dorsal
fin rays, anal
fin rays, left pectoral
fin rays, lateral line scales, scales above lateral line, scales below lateral line, transverse scale rows and preoperculomandibular canal pores.
The zebrafish caudal fin is composed of numerous
fin rays. The growth of the fin is controlled by the growth of independent
fin rays.
