Growth Modeling of the Giant Electric Ray <i>Narcine entemedor</i> in the Southern Gulf of California: Analyzing the Uncertainty of Three Data Sets
The age and growth rate of the giant electric ray, <i>Narcine entemedor</i>, was estimated using growth bands deposited in the vertebral centra of 245 specimens. Differences in size and age distribution were found between the sexes, a pattern that suggests the annual deposition of band p...

| description | The age and growth rate of the giant electric ray, <i>Narcine entemedor</i>, was estimated using growth bands deposited in the vertebral centra of 245 specimens. Differences in size and age distribution were found between the sexes, a pattern that suggests the annual deposition of band pairs, possibly occurring in April. Multimodel inference and back-calculation were performed to three age data sets of females considering their reproductive cycle and time of capture, among which the von Bertalanffy growth function was found to be the most appropriate (<i>L</i><sub>∞</sub> = 81.87 cm TL, <i>k</i> = 0.17 year<sup>−1</sup>). Our research supports the idea that age can be determined via biological features such as birth date and growth band periodicity. We concluded that <i>N. entemedor</i> is of a moderate body size, moderate longevity and is a fast-growing elasmobranch species. |
