We propose a method for fitting growth curves to multiple recapture data of lobsters when the age at first capture is unknown. The von Bertalanffy growth curve is used to model the growth. To account for individual variability, the unknown age in logarithmic scale of a lobster at first capture, the individual asymptotic size, and the individual growth coefficient of its carapace length are modeled as random effects with a trivariate normal distribution. Unlike previously suggested models, the… Expand
Research on Lobster Age-Size Relationships: Developing Regionally Specified Growth Models from Meta-analysis of Existing Data
The stepwise growth model for the American lobster, Homarus americanus, presented here offers a novel approach to age estimation and its variability by integrating two growth analysis methods traditionally used independently, and is used to confirm age estimates in the latter. Expand
Estimation of growth parameters from multiple-recapture data.
This article develops a method for analysis of growth data with multiple recaptures when the initial ages for all individuals are unknown, which treats all the lengths including the length at first capture as correlated repeated measures for each individual. Expand

H hierarchical models in which growth curves vary as individual-specific stochastic processes are described, and it is shown how these models can be fit using capture-recapture data for animals of unknown age along with data for Animal of known age, and combined in a Bayesian analysis. Expand
Modeling individual specific fish length from capture-recapture data using the von Bertalanffy growth curve.
It is found that untestable hierarchical assumptions placed on the nuisance parameters in each model can influence the resulting inference about parameters of interest and researchers should carefully consider these assumptions when modeling growth from tag-recapture data. Expand
Use of Bayesian hierarchical models to estimate northern abalone, Haliotis kamtschatkana, growth parameters from tag-recapture data
Bayesian hierarchical models were developed to estimate the growth parameters of northern abalone, Haliotis kamtschatkana, using tag-recapture data with a mixture of single and multiple recaptures, and fit the data well based on the Bayesian p-values. Expand
A diffusion process to model generalized von Bertalanffy growth patterns: fitting to real data.
A stochastic model related to the generalized von Bertalanffy growth curve is proposed that allows to investigate the time evolution of growth variables associated both with individual behaviors and mean population behavior and an application to real data of mean weight of swordfish is presented.

Reconciling larval and adult sampling methods to model growth across life-stages
This work model the growth of the endangered Reticulated Flatwoods Salamander, Ambystoma bishopi, in a Bayesian framework, that accounts for unknown ages, individual heterogeneity, and reconciles dip-net and drift fence sampling designs and finds evidence for marked variability in growth rate, the timing and age at metamorphosis, and maximum size, within populations.

Various drivers in determination of the growth pattern of crustaceans were evaluated, including life history strategy and environmental stress, including environmental factors into the development of growth models and the recent progress in age-determination were highlighted. Expand


Application of Nonlinear Models with Random Coefficients to Growth Data
SUMMARY The application of nonlinear random coefficient models to the analysis of growth curve data is described. The approach is further developed for the estimation of mean growth curves and theirExpand
Estimation of von Bertalanffy growth curve parameters from recapture data
A simple method of constructing estimating functions for parameters in the von Bertalanffy growth model E[y(t)] = L[1 - exp(-Kt)] is presented for tag-recapture data when the age of the animal isExpand
An Analysis of Two Methods of Fitting the von Bertalanffy Curve to Capture-Recapture Data
Neither method is trustworthy and a new method is required, under reasonably realistic assumptions on the growth of an animal, in the case of constant recapture intervals. Expand
The use of generalized linear modelling to determine inter-annual and inter-area variation of growth rates: the Cape rock lobster as example
The analysis reveals that the recent decline in growth rates of the Cape rock lobster is actually more dramatic, relative to historic growth, than suggested in previous more limited analyses. Expand
