Age, growth and length at first maturity of Otolithes ruber in the Northwestern part of the Persian Gulf, based on age estimation using otolith
Estimates of age, growth parameters, length-weight relationship and length and age at first maturity of the otolithes ruber are required for fishery management. We used counting annuli on the section of sagittal otoliths to age O.ruber from the Northwest Persian Gulf in south of Iran. Estimated ages ranged from 0 to 6 years, and maximum frequency of fishes was observed in age-group 1. The val...

متن کاملA Numerical Method for Estimating the Variance of Age at Maximum Growth Rate in Growth Models.
Studies on maturation and body composition mention age at peak height velocity (PHV) as an important measure that could predict adulthood outcome. The age at PHV is often derived from growth models such as the triple logistic fitted to the stature (height) data. Theoretically, for a well behaved growth function, age at PHV could be obtained by setting the second derivative of the growth functio...
متن کاملGenetic effects of spermatogonial irradiation on growth and age at sexual maturity in rats.
INTEREST in the genetic effects of irradiation on quantitative characters usually takes the form of two questions. Does irradiation effect a genetic change in the mean of quantitative characters such as human intelligence? Does irradiation induce genetic variance in quantitative characters that could be utilized by the plant or animal breeder for genetic improvement? Experimental data relevant ...
متن کاملGrowth and age at maturity of North American tortoises in relation to regional climates
GERMANO, D.J. 1994. Growth and age at maturity of North American tortoises in relation to regional climates. Can. J. Zool. 72: 918-931. North American tortoises (Gopherus spp.) are long-lived species that occur in a variety of habitats. I described growth of tortoises using Richards' growth model based on measures of scute annuli. Gopherus flavomarginatus is the largest species and grows the fa...
