BACKGROUND The channel catfish (Ictalurus punctatus), a species native to North America, is one of the most important commercial freshwater fish in the world, especially in the United States' aquaculture industry. Since its introduction into China in 1984, both cultivation area and yield of this species have been dramatically increased such that China is(More)
Macropodus opercularis is a popular ornamental fish and has been widely transported around the world. In this study, the complete mitochondrial genome of M. opercularis was reported. The circular genome is 16,496 bp in length and consists of 13 protein-coding genes, 22 tRNA genes, two ribosomal RNA genes, and one control region. The overall nucleotide(More)
It has been proved by experiments that the metal magnetic memory (MMM) NDT method can effectively detect the stress concentration of ferromagnetic metal parts. But it is still hard to evaluate the stress concentration quantitatively because of the confusion in the mechanism of MMM method. In this paper experiments are designed and carried out to investigate(More)
The complete mitochondrial genome of Neosalanx tangkahkeiis was determined to be 16,550 bp in length with (A+T) content of 49.7%, and it consists of 13 protein-coding genes, 22 tRNAs, 2 ribosomal RNAs, and a control region. The gene composition and the structural arrangement of the N. tangkahkeiis complete mtDNA were identical to most of other vertebrates.(More)
Genetic diversity and population structure of yellow catfish Pelteobagrus fulvidraco were examined by using mitochondrial DNA control region sequences in 143 specimens sampled from five lakes in the middle and lower reaches of the Yangtze River, China; 151 polymorphic sites defined 72 distinct haplotypes. Haplotype diversity indices (0.903-0.953) and(More)
Perccottus glenii is a species of freshwater sleeper native to the Russian Far East, north-eastern China, and the northern part of the Korean Penninsula with introduced populations in other regions of Eurasia. In this study, a new complete mitochondrial genome of Perccottus glenii was reported. The circular genome is 16,510 bp in length and consists of 13(More)
Passive integrated transponder (PIT) tags can be used to overcome environmental variations caused by individual fish tanks during family selection of the channel catfish (Ictalurus punctatus), which thus permits growth comparisons among different families under identical environmental conditions. Power analysis was used to analyse variations in various(More)
The F1 hybrids of female channel catfish × male blue catfish contain many desirable traits for commercial production. But hybrid catfish cannot always be easily distinguished from channel catfish. It is also difficult to identify fingerlings and fillets of blue catfish, channel catfish and F1 hybrids. The present research showed that a trinucleotide(More)
Analyzing the practice in the university ecological development of landscape, it is the fact that universities have entered the period of ecological transition of landscape. According to the example in the University of Santa Cruz, the article has showed the character in the ecological practice of university landscape and raised the involving strategy of(More)
