Serum complement is valuable tool in determining the health status of fish. This study was conducted to examine in vitro activity of serum complement as an indicator of innate immunity in four sturgeon species, Acipenser stellatus, A. baeri, A. nudiventris and Huso huso (Chondrostei: Acipenseridae). The Effects of different temperatures, concentrations and volumes of serum on alternative comple...

  Glyphosate, N–(phosphonomethyl) glycine, has been widely used to control agricultural weeds in the north of Iran. However, it is also supposed to have adverse effects on natural sturgeon population. The present study was undertaken to evaluate the acute toxicity of glyphosate to three different sturgeon species (Huso huso, Acipenser stellatus, and A. persicus) under laboratory conditions. Fis...

Sphaerobolus stellatus Tode is a fascinating gasteroid fungus that distinguished from other fungi by the diminutive morphology of starry basidiome when mature and its peculiar strategy spore’s dispersion. This taxon ejects gleba for considerable distance as if it was cannon, therefore popularly known artillery fungus. Although species cosmopolitan, records are seldom in regions such South Ameri...

Acipenser stellatus (stellate sturgeon) represents a sturgeon species of great importance for the scientific community and fishermen that has been intensively captured for decades. Besides of overfishing and poaching, their reproduction sites have been destroyed and their natural habitats were affected by pollution. In consequence, wild populations of stellate sturgeon have decreased dramatical...

this study was investigated the effects of dietary estradiol-17? (e2) on growth, body composition and blood indices in acipenser stellatus. fish (40.9 ? 1.1 g average initial weight; n = 60 per group) were fed with three different diets containing 0 (control), 25 and 50 mg kg-1 dietary estradiol contents to apparent satiation for seven months. the results suggested that growth rate were decreas...

The effects of dietary phospholipids (PL) on the performance juvenile stellate sturgeon (Acipenser stellatus) was evaluated in terms growth and feed efficiency parameters, muscle liver fatty acid profiles, activity digestive antioxidative stress enzymes, expression lipoprotein lipase (lpl) insulin-like factor (igf1). For this purpose, seven isoproteic (44% crude protein) isolipidic (17% fat) di...

Starry flounder (Platichthys stellatus) is an important sport and food fish found around the margins of the North Pacific. Aquaculture production of this species in Korea has increased because of its commercial value. Microsatellite DNA markers are a useful DNA-based tool for monitoring the genetic variation of starry flounder populations. In this study, 12 polymorphic microsatellite DNA marker...

Pitaya (Hylocereus undatus) is a non-climacteric fruit that reaches its best eating quality when harvested ripe, decreasing thereafter during storage (CHIEN et al., 2007). As a new crop, there have been limited studies focused on extending the postharvest quality of pitaya fruit. The main postharvest problems of pitaya fruit are mechanical injury, chilling injury, decay, and water loss (NERD et...
