1. West et al . (2001) describe a general model of ontogenetic growth in which growth represents the surplus of energy acquisition over maintenance energy requirement, which themselves are allometric (power) functions of body mass with exponents 3 / 4 and 1, respectively. Furthermore, the intercept of the maintenance requirement decreases with the – 1 / 4 power of adult mass. 2. These relations...

conclusions the high prevalence of vwd among our patients was the same as other previous reports, suggesting low awareness about this disease and under diagnosis of mild cases. results mean age of our patients was 32.5 ± 10.6 years. the level of von willebrand factor in 22.5% and von willebrand activity in 19.6% of patients was abnormal. the prevalence of vwd among patients with menorrhagia was...

Examining temporal changes in the growth and generation time of fish species can be valuable for understanding population responses to different management measures environmental conditions. Atlantic herring (Clupea harengus) is an ecologically commercially important pelagic forage that occupies southern Gulf St. Lawrence. Here, we developed von Bertalanffy curves estimated yearly values NAFO D...

Determining both the age structure and growth pattern allows to establish causal factors, environmental and/or genetic, that eventually may be responsible for observed of divergence. We examined variation in across populations two toad species, Pelobates cultripes Epidalea calamita exhibit a geographic body size southern Spain. For differed mean but did not correlate with populations. Although ...

Bu çalışmada, Eğirdir Gölü’nün endemik balık türlerinden Ot Sazanı (Pseudophoxinus egridiri)’nin büyüme özellikleri incelenmiştir. Örnekleme çalışmaları, gölde belirlenen 5 istasyonda Haziran 2010 – Mayıs 2011 tarihleri arasında aylık olarak yürütülmüştür. çalışmaları sonucunda toplam 544 birey elde edilmiştir. Örneklemelerden edilen bireylerin total boyları 2,1 cm ile 10,0 cm, ağırlıkları 0,11...

To describe the growth pattern of bonnethead shark (Sphyrna tiburo) in Gulf Mexico, a von Bertalanffy (VB) model has been automatically fit, which indicated single−phase continuous without oscillations, though this would generate biases if hypothesis is not confirmed. The objective research was to S. tiburo under multimodel approach based on information theory and contrasting models (VB, Gomper...

in this study, population dynamics of venerid bivalve paphia cor was investigated for a one-year period (2008-2009) in bushehr shoreline areas (50˚ 40´ e- 29˚ 14´n) to estimate the stock abundance, growth parameters and natural mortality. sampling was carried out bi-monthly by transects at random direction and zigzag pattern with duplicated quadrate (0.25 m2). the length frequency was used to e...

This study was conducted to compare some nonlinear functions to describe the broiler growth curve of the Cobb500 strain. A flock of fifty one-day-old chicks were randomly selected from a henhouse of 2500 chicks. Our goal was to establish a growth curve using weighting data using mathematical solutions of time-dependent differential functions. In total, six equations were subjected to a statisti...

In this study, the growth and age characteristics of Okamejei kenojei in West Sea South Korea were examined, specimens collected by bottom trawls from January to December 2019. The relationship between disc width (L) body weight (W) was W = 6.1 × 10−3 L3.40. Age determined measuring annuli on vertebral centrum surface, which forms around June every year. spawning period extrapolated monthly cha...
