The vertebral column of the Florida manatee presents an unusual suite of morphological traits. Key among these are a small precaudal count, elongate thoracic vertebrae, extremely short neural spines, lack of a sacral series, high lumbar variability, and the presence of six instead of seven cervical vertebrae. This study documents vertebral morphology, size, and lumbar variation in 71 skeletons ...

in this study 485 specimen of garra rufa (heckel, 1843) from 29 populations from six river systems and basins including tigris, karkheh, karun, persis (helleh and mond), hormuz and maharlu were collected by a 5mm mesh sized seine net, anesthetized in 1% clove oil solution, fixed in 10% formalin and transferred to the laboratory for further investigations. some 28 morphometric, 25 morphometric p...

Apart from the well-demarcated genera Auchenoglanis and Parauchenoglanis, Auchenoglanidinae, one of the two sub-families of the African catfish family Claroteidae, suffers from poor resolution at the generic level. For the remaining genera, Notoglanidium, Liauchenoglanis, Platyglanis and Anaspidoglanis, generic discriminations are rudimentary. In addition, several included species are poorly de...

studies on the biometric parameters of a species to have an important role in its population or stock management and conservation. present study investigated the morphometric, meristic, length-weight relation (lwrs), length-length relation (llrs) and growth status (k and kn) of the redline torpedo barb, p. denisonii collected during august 2012 to july 2013 from river valapattanam, kerala. the ...

The study investigated morphometric and meristic measurements, length-weight relationship (LWR) relative condition factor (Kn) of the Sphyraena obtusata from south-eastern Arabian Sea August 2019 to March 2020. Three hundred fifty two specimens having a length weight range 16.5 – 30.1 cm 29.54 155.20 g, respectively were analyzed for morphological measurements (13 11 meristic), LWR factor. maxi...

Information on the biometric characteristics, egg morphology, and habitat of O. javanicus are very important for its use as model fish in laboratory, ornamental fish, environmental bioindicators. Therefore, research is needed to analyze character, ricefish brackish water pond Banten Bay. This was conducted non-eperimentally by observing characters examine meristic, morphometric, sex dimorphism ...

Background: An understanding of the stock structure commercially exploited species is important for effective fisheries management. The white sardine Escualosa thoracata (Valenciennes, 1847) forms a significant fishery along with both costs India. decline in resource landings during last decade whole range its distribution necessitated recent deliberations to recognize likely existence stocks. ...
