the effects of weight and length of barbus grypus broodstock on fingerlings reproductive characteristics and growth were investigated. we chose three female treatments  including weight and length groups (1) 2212.5±479g,  62.68±6.7cm, (2) 4518±780g,  79.12±4.36cm  and (3) 7712.5±1171g, 92.62±3.13cm. the same male broodstock were used for all the treatments with the weight and length size of 140...

Changes of fat distribution were followed up in Czech and Slovak children from 1.5 to 15 years of age, using centrality indices, which relate the values of skinfolds on the trunk to the skinfolds on the extremities, head and neck. Up to 5 years of age, subcutaneous fat was deposited relatively more on the extremities, head and neck than on the trunk, which was expressed by lower values of the c...

This study compares urban landscapes in the Portland and Los Angeles metropolitan areas at the neighborhood level by operationalizing six smart growth indices and mapping their spatial distribution patterns and time trends. Analysis results show that the two metropolitan areas have both strengths and weaknesses in different aspects of smart growth. Most neighborhoods in both regions do not exce...

Research on regulatory mechanisms in biological populations often focuses on environmental covariates. An integrated approach that combines environmental indices with organismal-level information can provide additional insight on regulatory mechanisms. Survival of spring/summer Snake River Chinook salmon (Oncorhynchus tshawytscha) is consistently low whereas some adjacent populations with simil...

BACKGROUND: The immunostimulating effect of Aloe vera in mammals has been documented, but few works were done on effect of A. vera on fish health and immune responses. OBJECTIVES: In this study the effect of oral administration of A. vera on growth indices, hematological parameters and immune responses of rainbow trout were investigated. METHODS: One thousand five hundred rainbow trout fingerli...
