PCR analysis generated on the genetic data showed that the geographic hairtail (Trichiurus lepturus) population from Korea in the Yellow Sea was more or less separated from geographic hairtail population from China in the South Sea. The average bandsharing value (mean±SD) within hairtail population from Korea showed 0.859±0.031, whereas 0.752±0.039 within population from China. Also, bandsharin...

Knowledge of length-weight relationships for commercially exploited fish is an important tool for assessing and managing of fish stocks. However, analyses of length-weight relationship fisheries data typically do not consider the inherent differences in length-weight relationships for fish caught from different habitats, seasons, or years, and this can affect the utility of these data for devel...

This study investigated the response of the ichthyoplankton community to environmental changes in the Yangtze Estuary using canonical correspondence analysis. Ichthyoplankton community and environmental data were recorded during the autumns of 1998, 2000, 2002, 2003, 2004, 2007 and 2009. Among the ichthyoplankton, the dominant larval and juvenile families were the Engraulidae, Gobiidae and Sala...

Sequences of the complete mitochondrial cytochrome oxidase subunit I gene were used to identify Trichiurus species and examine their population genetic structure demographic history along coast China. Three found. japonicus lives in colder waters continental shelves China Seas, while nanhaiensis warmer slopes South Sea, brevis shallow Sea. The migrations these mainly associated with feeding spa...

A study was carried out to determine the prevalence of parasitic infections among the nomadic Fulanis of south-eastern Nigeria between September 2003-March 2004. Urine, stool and blood specimens were collected from each of 231 subjects. Of these, 98 (42.4%) were infected with one or more of 14 parasitic species, of which Plasmodium malariae had the highest prevalence (15.3%). Others included 6 ...

This study attempts to look into the energetic status of demersal fish species with their maturity stages and evaluate their energetic condition. Demersal fish species from wild were captured, total length and weight of each fish were measured and gonads were observed, weighted and collected with fish flesh. Gonadosomatic index, water content of gonad and flesh and gonadal and somatic caloric v...

the lernaeopodidae is a cosmopolitan family of copepods parasitic on both elasmobranchs and teleosts in marine and freshwater habitats. trichiurus lepturus l. is a commercially valuable bentho-pelagic fish inhabiting continental shelves and slopes worldwide. in the present study 74 specimens of t. lepturus were caught in the persian gulf, 12 of which were infected with female brachiella trichiu...
