Present study describes the length-weight (LWR) and length-length (LLR) relationships of a freshwater catfish Eutropiichthyes vacha Hamilton from Indus River, Sindh, Pakistan. A total of 281 specimen of E. vacha were collected from fisherman?s catch from February 2005 to January 2006, are used for this study. The parameters a and b of the length-weight relationship were calculated as W= aLb are...

the black-striped pipefish, syngnathus abaster, is a species of the syngnathidae family. this study provides data on the morphometric, meristic and genetic structuring of the caspian sea pipefish, syngnathus abaster. eight morphometric characteristics based on total length and five morphometric characteristics based on standard length were analyzed. a total of 50 specimens were collected in bra...

Intra Uterine Growth Retardation (IUGR) refers to insufficient fetal growth diagnosed either by two direct intrauterine growth assessment (ultra-sonography) or when the fetus or newborn length (height) is less than two standard deviations (or third percentile) below the mean for gestational age (NIKLASSON et. al. 1991; DE ZEGLER 1997). When the fetus or newborn body size (wight or length) is in...

OBJECTIVE Grammatical development is shown to be delayed in CI children. However, the literature has focussed mainly on one aspect of grammatical development, either morphology or syntax, and on standard tests instead of spontaneous speech. The aim of the present study was to compare grammatical development in the spontaneous speech of Dutch-speaking children with cochlear implants and normally...

the present research aimed to study the growth and reproductive parameters of common kilka clupeonella caspia in southern caspian sea in 2010. after measuring the length and weight of 3774 samples, they were dissected, sex determined and female gonads were weighed. sexual maturity classification was carried out based on six stages. age was determined using sagitta otoliths. length-weight relati...

A simple method to determine the focal length of a lens using the Talbot image is presented. This method uses only one grating, requiring neither Moiré fringe analysis nor the angle between the gratings. The original Fourier transform was used to access the spectrum beyond the limitation set of the usual fast Fourier transform to determine the (de)magnification accurately enough to be used for ...

this study evaluates changes in species composition, catch, and cpue of three species of kilkas in the caspian sea from 1961 to 2009. the effects of fluctuations in sea level rise and fall on the catch of kilka as well as the impacts of a recent invasion by mnemiopsis leidyi (ctenophora) were assessed in terms of species composition and cpue of kilkas in the iranian coastal region of the caspia...

The main target species of Japanese purse seine operating in the tropical waters of the western Pacific Ocean is skipjack tuna (Katsuwonus pelamis) and yellowfin tuna (Thunnus albacares), which account for nearly 98 % of their total catch in weight and the remaining is bigeye tuna (Thunnus obesus) according to the catch based on logbook data. The recent study of the vertical distribution of the...
