the black-striped pipefish, syngnathus abaster, is a species of the syngnathidae family. this study provides data on the morphometric, meristic and genetic structuring of the caspian sea pipefish, syngnathus abaster. eight morphometric characteristics based on total length and five morphometric characteristics based on standard length were analyzed. a total of 50 specimens were collected in bra...

This study was conducted to evaluate the effects of herbal extracts on quality striped catfish (Pangasianodon hypophthalmus) fillets throughout storage period. Quality changes during ice were studied after dip treatments in aqueous solutions ethanolic extract Phyllanthus amarus (0.02% and 0.04%, w/v) or Euphorbia hirta (0.06% 0.02%, w/v). The control (dipped tap water) treated fish samples anal...

The fatty acid composition of farmed Tra catfish (Pangasius hypophthalmus) was determined and compared to farmed Atlantic salmon (Salmo solar) and to wild-caught Asian seabass (Lates calcarifer). Saturated fatty acids (SFA) were most abundant in catfish (42.6%) while salmon (37.2%) and seabass (39.0%) were rich in polyunsaturated fatty acids (PUFA). Tra catfish contains Docosahexaenoic acid (DH...

Six different composite packaging materials were tested with the trades’ practice of polythene bags in storing smoked catfish for a period of six months. The thickness of the packaging materials ranges from 0.23 to 046 mm with water and oil absorption rates of the packaging materials varies from 0.23 to 10.00 and 0.28 to 10.857 glcm2/mm respectively. The impact resistance weight also varies fro...

White-throated sparrows (Zonotrichia albicollis) exhibit a genetic polymorphism that affects plumage and behavior in both sexes. White-striped morphs are more territorially aggressive, whereas tan-striped morphs provision nestlings at a higher rate. We investigated testosterone physiology in this species in an effort to understand hormonal mechanisms for the observed differences in aggression a...

The double-crested cormorant, Phalacrocorax auritus, is considered the primary depredating bird species on commercially produced channel catfish, Ictalurus punctatus, in the southeastern USA. We simulated different levels of cormorant predation on losses at harvest and economic effects on channel catfish production in a multiple-batch cropping system. We observed significant (P< 0.05) declines ...

—Blue catfish Ictalurus furcatus are a big river species, native to major rivers of the Mississippi River basin and Gulf Coast streams of the central and southern United States, south into Mexico, northern Guatemala, and Belize. Blue catfish are native in 20 states and have been introduced into nine others, mostly along the Gulf, Atlantic, and Pacific slopes. Blue catfish are largest of the ict...

UNLABELLED Since 2009, catfish farming in the southeastern United States has been severely impacted by a highly virulent and clonal population of Aeromonas hydrophila causing motile Aeromonas septicemia (MAS) in catfish. The possible origin of this newly emerged highly virulent A. hydrophila strain is unknown. In this study, we show using whole-genome sequencing and comparative genomics that A....

Dieldrin accumulation and elimination in muscle tissue of channel catfish (Ictalurus punctatus) from water and food was determined in the laboratory. Twenty-eight-day exposure of fish 150-225 mm and 350-400 mm long to 75 parts per trillion (ng/liter) dieldrin resulted in the larger catfish consistently accumulating more dieldrin than the smaller fish. After 28 days of elimination, dieldrin leve...
