the aim of this study was to provide necessary information on the age, growth and sex ratio of one of commercially important cyprinid species, alburnus chalcoides in the southern caspian sea (north iran) from 2010 through 2011. 53 specimens of both sexes (males and females) were collected monthly. the samples were transported tothe laboratory for further biological measurements and otolith extr...

Fifteen Hereford and 47 crossbred heifers were allotted by breed and body weight to be artificially inseminated to one of two Angus sires selected for progeny birth weights (L = low; H = high). Forty-two of the heifers were randomly assigned to be slaughtered at 200, 215, 230, 245 or 260 d of gestation for measurement of fetal and placental characteristics. Twenty heifers were allowed to go to ...

In this paper age determination and morphological characteristics of blacktip catfish, Plicofollis dussumieri, from Oman Sea were evaluated. A total of 132 fish specimens were collected from fishing trawlers or landings from March 2011 to July 2012, with minimum and maximum of 245 mm, 195 g and 767 mm, 5801 g, respectively. Maximum life span was 12 years for the length range of 245 – 767 mm FL,...

Ages of yellowfin grouper (n = 306) from the southeastern United States coast from 1979-2014 were determined using sectioned sagittal otoliths. Opaque zones were annular, forming January-June (peaking in February-March). Yellowfin grouper ranged in age from 3 to 31 years; the largest fish measured 1,000 mm fork length (FL). Body size relationships for yellowfin grouper were: W = 1.22 × 10(-5) F...

one of the major goals of antenatal care is estimation of gestational age.the most widely used parameters for evaluation of fetal growth are biparietal diameter (BPD),femoral length (FL) and adbominal circumference (AC).to determine the value of prenatal ultrasonographic scapula measurements for fetal growth and gesattional age a prospective ultrasonographic cross-sectional study was conducted ...

The length–weight relationship, length–length relationship and the condition factor values of Tench, Tinca tinca (L., 1758) inhabiting Sıddıklı Dam was described in this study. A total 102 specimens captured between September 2015 August 2016 were used to conduct For each individual, length (TL), fork (FL) standard (SL) as well body weight measured. Sex composition determined 49.02 % female, 43...

Above, w ∈ Rd is a vector of real-valued weights, which we call a weight vector, and θ ∈ R is a threshold value. The weight vector (assuming it is non-zero) is perpendicular to a hyperplane of dimension that passes through the point wθ/‖w‖2; this hyperplane separates the points x ∈ Rd that are classified as +1 from those that are classified as −1 by fw,θ. Homogeneous half-space functions are ha...
