a 15-landmark morphometric truss network system was used to investigate the hypothesis of population fragmentation of shad fish alosa braschnicowi borodin, 1904 along the southern caspian sea. a total of 181 a. braschnicowi specimens were caught from six localities, respectively from the west to the east including; astara, rezvanshahr, anzali, tonekabon, sari and miankale. principal component a...

Chlorella kessleri, Fructosebisphosphatase, Superose-FPLC, DEAE-Chromatography, Enzyme Oligomerization In crude extracts of Chlorella kessleri two forms of fructosebisphosphatase can be separated by ion exchange chromatography or by acid precipitation. FBPase I is eluted from DEAE cel­ lulose at 200 m M KC1 and precipitated at pH 4.5, FBPase II is correspondingly eluted at 310 m M KC1 and solub...

Allis shad Alosa alosa hatches and develops in freshwater before migrating to the sea during its first months of life. Some field research works dedicated diet species put forward that young stages allis feed mainly on zooplankton, being opportunistic euryphagous; their would diversify through ontogeny relation growth. However, these assumptions have never been confronted availability prey, exa...

In June and July 2000, Otsego Lake was stocked with 80,000 Oneida Lake strain pond fingerling walleye (Stizostidion vitreum) averaging 48mm in total length (TL) (range= 32-56mm) with the primary goal ofre-establishing walleye to the lake. The yearly stocking ofthis number of walleye will continue to at least 2003. It is expected that walleye will forage primarily upon alewives (Alosa pseudohare...
