Comparison of Electronic Length Frequency Analysis (ELEFAN) for Estimation of Growth Parameters for Lollyfish, Holothuria (Holothuria) atra and Sand Sea Cucumber, Holothuria (Thymiosycia) arenicola (Holothuroidea: Echinodermata) in the North Arabian Sea, Pakistan

Marine Science and Technology Bulletin, 2020
To estimate the growth parameters, the non-seasonal von Bertalanffy and Hoenig seasonal von Bertalanffy models were fitted to the length frequency data of Holothuria atra and H. arenicola obtained from coastal areas of Karachi in the northern Arabian Sea,

A note on the von Bertalanffy growth function concerning the allocation of surplus energy to reproduction [PDF]

, 2012
We propose an extended form of the von Bertalanffy growth function (VBGF), where the allocation of surplus energy to reproduction is considered. Any function can be used in our model to describe the ratio of energy allocation for reproduction to that ...

Metabolic rate and growth in the temperate bivalve Mercenaria mercenaria at a biogeographic limit, from the English Channel

, 2010
Metabolism and growth rate of the hard clam, Mercenaria mercenaria, were investigated in a population invasive to Southampton Water, southern England. An individual metabolic model expressed as a function of soft tissue dry mass was fitted to data of 18 ...

Using Periodic Matrix Models to Simulate the Effectiveness of Alternative Reintroduction Strategies for Lizards on a Seasonal Tropical Island

Animal Conservation, EarlyView.
Guam's lizard fauna has been devastated by the invasive brown treesnake, but recent advances in brown treesnake control have opened the possibility of reintroducing native lizards. We simulated different strategies for reintroducing lizards to Guam, comparing the timing and age‐structure of releases.

Validation of age determination methods and growth studies of the sand sole Pegusa lascaris (Soleidae) from the eastern-central Atlantic

Ciencias Marinas, 2011
The age and growth of the sand sole Pegusa lascaris from the Canarian Archipelago were studied from 2107 fish collected between January 2005 and December 2007.

Growth and Variation in Fallow Deer (Dama dama L.) From Two Contrasting Habitats in Southern Britain

Acta Zoologica, EarlyView.
ABSTRACT We have compiled a unique data set on the age, sex, body weight and dimensions of over 500 European fallow deer from two contrasting areas of habitat in southern England: a high‐density managed parkland population and a lower‐density feral woodland one.

Von Bertalanffy's dynamics under a polynomial correction: Allee effect and big bang bifurcation

, 2016
In this work we consider new one-dimensional populational discrete dynamical systems in which the growth of the population is described by a family of von Bertalanffy's functions, as a dynamical approach to von Bertalanffy's growth equation.

Age and growth of swordfish (Xiphias gladius) caught by the Hawaii-based pelagic longline fishery [PDF]

, 2007
We verified the age and growth of swordfish (Xiphias gla-dius) by comparing ages determined from annuli in fin ray sections with daily growth increments in otoliths.
