In order  to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in Isfahan. The experiment was conducted as split plots in a randomized complete blocks design with three replications in Isfahan (51° 48' E, 32° 40' N).Main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class A and cultiv...

The length–weight relationships (LWR) of the common seadragon Phyllopteryx taeniolatus (Lacepède, 1804) and leafy Phycodurus eques (Günther, 1865), Syngnathidae, are presented in this paper, based on specimens raised Birch Aquarium at Scripps, La Jolla, California. Furthermore, we used length known age 40 15 seadragons to estimate parameter von Bertalanffy growth function (VBGF) for these speci...

The striped piggy, Pomadasys stridens (Forsskål, 1775), is a recent invasive fish species in the eastern Mediterranean. Although its population dynamics was investigated detail natural distribution area, western Indian Ocean, an important data gap still exists This study carried out to determine growth, mortality, and length–weight length–length relations of piggy right after establishment area...

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...

Abstract Length-weight relationships (LWR) were determined for Brotula barbata , Dentex angolensis macrophthalmus Neomerinthe folgori and Scorpaena stephanica using individual fish records collected between July 2002 January 2003, during a pilot project of experimental fishing over the shelf off Guinea Bissau. Fishes caught by commercial vessels bottom longline, measured defrost total length (t...

The basis used for expression of carbon dioxide exchange rate (CER) of single leaves may alter the relative ranking of genotypes being selected for a breeding program. Therefore, field and growth chamber experiments were conducted on 16 genotypes of tall fescue (Festuca arundinacea Schreb.) to determine the relative merit of expressing CER data on a leaf area or leaf weight basis. Genotypes wer...

Platoon based traffic flow models form the underlying theoretical framework in traffic simulation tools. They are essentially important in facilitating efficient performance calculation and evaluation in urban traffic networks. For this purpose, a new platoon-based macroscopic model called the LWR-IM has been developed in [1]. Preliminary analytical validation conducted previously has proven th...

The present study presents biological aspects of golden grey mullet, Liza aurata (risso, 1810) from Bardawil lagoon, Egypt. A total 1329 specimen's individuals were collected different landing sites Lagoon in the period May 2017 to February 2018. Length-weight relationship, condition factor, age composition, and fish growth studied. length weight ranged 12.2 33.6 (cm) 13.8 340 (g) respectively....
