Evaluation of organ distribution of microcystins in the freshwater phytoplanktivorous fish <Emphasis Type="Italic">Hypophthalmichthys molitrix</Emphasis>

To evaluate the public health risk of exposure to microcystins in fish food in China, the distribution pattem of microcystin-LR and microcystin-RR in various organs （liver, intestine, kidney, muscle and lipid） of the dominant freshwater phytoplanktivorous fish Hypophthalmichthys molitrix in Hangzhou, China＇s Tiesha River was investigated with the method of HPLC-ESI-MS analysis. The distribution of microcystins was different in the fish organs and the major total microcystins （microcystin-LR and microcystin-RR） were present in the intestines （6.49 μg/g fresh weight）, followed by the livers （4.52 μg/g fresh weight） and the muscles （2.86 μg/g fresh weight）. Microcystins were detected in kidneys （1.35 μg/g fresh weight）, but not detected in lipid. The results suggested that the mean daily intake from fish was 0.03 μg/kg body weight which was very close to the recommended WHO tolerable daily intake （TDI） level of 0.04μg/kg body weight per day, and local people were wamed they may have health risk if they consumed fish from the river.     

Influence of fasting on muscle composition and antioxidant defenses of market-size Sparus macrocephalus

The study was conducted to investigate fasting effects on flesh composition and antioxidant defenses of market-size Sparus macrocephalus. Two hundred fish （main initial weight 580 g） were divided into two groups （control and fasted） and reared in 6 cages. After two weeks of adaptation, group I fasted for 28 d; group II was fed normally as a control. In 3, 7, 14, 21 and 28 d, 6 fish per group were sampled for proximate flesh composition, liver antioxidant enzyme activities and malondialdehyde flesh content analyses. In fasted fish, the reduction of lipid content in muscle occurred after day 3, and, compared to controls, the content of protein decreased from day 14, the activities of liver antioxidative enzymes superoxide dismutase （SOD） and glutathione peroxidase （GPX） increased from day 3, and flesh malondialdehyde levels increased from day 21. Flesh fat reduction shows that fasting may be used as a technique to reduce flesh lipid content in Sparus macrocephalus. However, considering flesh protein loss and the subsequent oxidative stress, the fasting technique should be used with precautions.

Dam Fish There was a boy standing on a corner selling fish.He was saying,"Dam fish for sale,dam fish for sale." A preacher (说教者) walked up and asked why he was calling them dam fish.The kid said," I caught them at the dam (水闸),so they're dam fish." The preacher bought some,took them home and asked his wife to cook the dam fish.His wife looked at him in bewilderment (迷惑) and said,"Preachers arent't supposed (不应该) to talk like that." The preacher explained why they were dam fish,and she agreed to cook them.

On the Causes of Sun Quan＇s Later Action in Proclaiming Emperor than Cao Pi and Liu Bei
FU Kai-jing （School of Politics and Laws Science, Guangxi Teachers Education University, Nanning 530001, China） Abstract： There are five reasons for the fact that Sun Quan proclaimed himself emperor later than Cao Pi and Liu Bei. The direct cause is his fear of Liu Bei＇s revenge after attacking and occupying Jingzhou city; the strategic cause is that Sun Quan had a difficulty against two kingdoms, Wei and Shu, at the same time; the third cause lies in his lack of ability to gain victory over the world; the fourth cause lies in his ideal to occupy the area south of Yangtze River; the fifth cause lies in his character of moderation and endurance. danger did Sun Quan declared to be an emperor. Sun Quan owned political skills lacked the ambition to unifying the whole country Key words： Sun Quan ; proclaiming oneself emperor; Cao Pi ; Liu Bei Only after realizing there was no to handle bilateral ralations but

Effects of α-tocopheryl acetate supplementation in preslaughter diet on antioxidant enzyme activities and fillet quality of commercial-size Sparus macrocephalus

This study examined the effects of dietary α-tocopheryl acetate supplementation on antioxidant enzyme activities and fillet quality in commercial-size Sparus macrocephalus. Three hundred fish [main initial weight （350±12） g] were divided into three groups （E250, E500 and El000） and reared in 9 cages. The fish were fed for 8 weeks with three diets containing different levels of dietary α-tocopheryl acetate （289, 553, 1069 mg/kg）. Over the experimental period, fish were fed to satiation and reached a final mean weight of （465±28） g without significant body weight difference and proximate composition difference. Fillet α-tocopherol was significantly （P〈0.05） different between groups, reaching levels of 14.2, 22.1, 30.9 pg/mg fillet for groups E250, E500 and El000, respectively. Total serum superoxide dismutase （SOD） activity increased significantly （P〈0.05） in fish fed the diets high in α-tocopheryl acetate, but serum glutathione peroxidase （GPX） activity was unaffected. In storage on ice, fillets of fish fed the diets high in α-tocopheryl acetate exhibited significantly lower （P〈0.05） levels of oxidation. These results suggested that increased dietary α-tocopheryl acetate could increase its flesh deposition, increase the activity of SOD and prevent lipid peroxidation ofSparus macrocephalus fillets in retail storage on ice.

The Mississippi is one of the longest rivers in the world. It was called “The Father of Waters”by the American natives. Drinking water was got from the Mississippi by people in towns and cities. Water for industrial use was got from it by facto-ries. But today “The Father of Waters”is in trouble. A lot of large factories were built along the river. Millions of tons of in-dustrial water was poured into the river. Its water for drinking was no longer able to be used. Birds and fish wer…

Efficient gene editing in a medaka (Oryzias latipes) cell line and embryos by SpCas9/tRNA-gRNA

Generation of mutants with clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9)is commonly carried out in fish species by co-injecting a mixture of Cas9 messenger RNA(mRNA)or protein and transcribed guide RNA(gRNA).However,the appropriate expression system to produce functional gRNAs in fish embryos and cells is rarely present.In this study,we employed a poly-transfer RNA(tRNA)-gRNA(PTG)system driven by cytomegalovirus(CMV)promoter to target the medaka(Oryzias latipes)endogenous gene tyrosinase(tyr)or paired box 6.1(pax6.1)and illustrated its function in a medaka cell line and embryos.The PTG system was combined with the CRISPR/Cas9 system under high levels of promoter to successfully induce gene editing in medaka.This is a valuable step forward in potential application of the CRISPR/Cas9 system in medaka and other teleosts.
