By the end of 1995 china had set up 175 zoological gardens and zoological exhibition sites in public parks , 227 artificial breeding centers for wild animals , more than 60 large botanical gardens and 255 wild plant gene and cell banks to ensure the continuation of rare and endangered species of plants and animals , including the giant panda , chinese alligator , chinese sturgeon , white - flag dolphin , manchurian tiger , crested ibis , cathay silver fir , dovetree , cycas revoluta and camellia chrysantha tuyama 到1995年底,中國共建動物園和公園動物展區175個、各種野生動物繁殖中心(場) 227個,建立大型植物園60多個、野生植物引種保存基地255個,使大熊貓、揚子鱷、中華鱘、白暨豚、東北虎、朱? 、銀杉、珙桐、蘇鐵、金花茶等珍稀瀕危動植物得到保護。

It is effective in controlling different phytophagous pests of field crop , ornamentals , vegetables , fruits and in controlling fire ants . to assess the potential impact of avermectins on the environment , the bioaccumulation potential of avermectin b1a , its major component , in sturgeon ( a . schrenckif ) was examined 本文對阿維菌素( avermectin , avm )環境毒理的一部分內容進行試驗研究,主體試驗部分為研究進入到淡水中的阿維菌素在鱘魚體內的生物富集和生物消除規律。

Compounds with bcf values < 100 are considered to be of little environmental concern and not expected to bioconcentrate into tissues . in this in vivo test , the low uptake of avermectin b1a and its low persistence in sturgeon muscle demonstrate that it will neither bioaccumulate in individual organisms nor biomagnify in the food chain 在試驗中,鱘魚對水中的avmb _ ( 1a )攝取率較低, avmb _ ( 1a )在鱘魚體內消除迅速,以及avmb _ ( 1a )較低的bcf值,表明不易在水生生物食物鏈中被生物濃縮,不易在水生生物體內富集,對環境和人類的健康影響較小。

Finger 4 : in the rearing pool at the yangtze river fisheries research institute of the chinese academy of fishery sciences , the fries of wild chinese sturgeon mother : the fries , which are successful artificially incubated , are eating breakfast with tasty relish - - aquatic earthworm , which look like red filament 圖四:長江水產研究所的幼鱘飼養池里,野生中華鱘媽媽的孩子們:一尾尾人工孵化成功的小中華鱘們正津津有味地吃著早餐:紅紅的如同細線的水蚯蚓。

A rapid uptake of avermectin b1a was observed and steady - state levels were reached within 14 to 18 days . depuration of avermectin bia residues in muscle of sturgeon was relatively rapid with more than 50 % clearance occurring after about 4 - 6 days in control water Avmb _ ( 1a )在鱘魚體內的殘留消除比較迅速,大約經過4 - 6天的消除期,體內殘留量大約消除50 ;經過14 - 18天的消除期,體內殘留量消除超過95 。

The method for determining avermectin ( avm ) in muscle of sturgeon ( a . schrenckif ) by high performance liquid chromatography with fluorescence detector was established . the homogenized muscle sample was extracted by acetonitrile , following centrifugation at 3000 g for 15 min 采用乙腈作為肌肉中蛋白沉淀劑和阿維菌素的提取劑,經堿性氧化鋁spe柱純化,蒸干和衍生化,用高效液相色譜( hplc )檢測。

The kremlin leader , who is due to step down at the end of his second term next march , looked every bit the seasoned campaigner when he lifted the sturgeon at a fish farm in southern russia and gave the creature a peck on the head 即將于明年三月在第二屆任期結束后卸任的克林姆林宮領袖當在俄國南部的一家漁場捧起一條鱘魚并在魚額頭上吻了一下的時候全然看上去是象是一位有經驗的競選者。

Moscow ( reuters ) - russian police battling fish smugglers have deployed a cat to sniff out contraband , including caspian sea sturgeon , the fish that produce russia ' s world - famous caviar 莫斯科(路透社)目前,正與魚走私者進行斗爭的俄羅斯警方配備了一只貓,來嗅出違禁品,其中包括里海鱘魚,這種魚可用來制造馳名世界的俄羅斯魚子醬。

According to the biological characteristic , especially the reproductive habit , the present resources and economical value , measurements of protection and development of the sturgeon fishery were put forward 根據黑龍江鱘科魚類資源現狀、群體結構變動情況及其生物學特點,闡明了保護和發展黑龍江鱘科魚類的必要性并提出了建議。

The postpartum chinese sturgeon mother can be keep alive above the situation breaking an abdomen fetching an ovum but being certain to die after laying , which has already been an extraordinary progress at present 在其它大型鱘魚類目前還處于破腹取卵而產后必死無疑的狀況下,中華鱘產后親魚可以保活已經是了不起的進步。

Sturgeon , or call stone old ghost , head cuirass is hexagonal , chela is sufficient powerful , sufficient edge back an abdomen provides bristle , congeneric kind more , or viridescence color , or he gong is lubricious 鱘,或稱石老鬼,頭胸甲為六角形,螯足強大,足背腹沿具剛毛,同屬種較多,或青綠色,或赫紅色。

Stocks of the caspian ' s beluga sturgeon have dropped by about 90 percent over the past two decades due to destruction of spawning sites , pollution and the end of soviet - era fishing regulation 由于產卵地被破壞、環境污染和前蘇聯時期捕撈規定的取消,在過去的20年中,里海鱘魚的數量比原先減少了90 % 。

Catching flower crab and sturgeon basically rely on dragnet exercise and gill net exercise , and cockboat door is multi - purpose and latter , in cloth net sea , crab touchs be pestered to manacle 捕撈花蟹和鱘主要靠拖網作業和刺網作業,而小艇戶多用后者,布網海中,蟹觸之被糾纏束縛。

Russia temporarily stopped exporting black caviar and halted commercial fishing of sturgeon in the caspian sea recently in an effort to save the fish from extinction 為了保護鱘魚使之免于滅絕,俄羅斯最近暫時停止了黑魚子醬的出口,并停止在里海的商業性捕魚行動。

Population of the chinese sturgeon migrates to yangtze river every year has decreased from about 2176 individuals shortly after ge zhou damming to 1000 or so at present 每年洄游至長江的中華鱘產卵群體數量,已從葛洲壩截流初期的約2176尾下降到目前的1000尾左右。

The fish farm is part of efforts to regenerate the caspian ' s endangered sturgeons , prized for their tiny black eggs used to make caviar 這座漁場是為了讓里海的瀕臨滅絕的鱘魚重新復興所做出努力工作的一部分。鱘魚因為其用于做魚子醬的極小黑色魚卵而珍貴。

Overfishing threatens the sturgeon population , to the point that environmentalists advocate banning sturgeon fishing completely until the population recovers 因為過度的捕撈鱘魚威脅到這種魚類的數量,所以環保工作者們提倡禁止捕撈鱘魚直到鱘魚數量回升。
