This study was conducted to evaluate the influence of dietary lysophospholipids combined with 1%dietary fish oil reduction on the growth performance and hepatic lipid metabolism of largemouth bass(Micropterus salmoides).Five isonitrogenous feeds were prepared with lysophospholipids at 0%(fish oil group,FO),0.05%(L-0.05),0.1%(L-0.1),0.15%(L-0.15)and 0.2%(L-0.2),*** dietary lipid was 11%in the FO diet and 10%in the other *** bass were fed for 68 d(initial body weight=6.04±0.01 g)with 4 replicates per group and 30 fish per *** results showed that the fish fed diet containing 0.1%lysophospholipids had higher digestive enzyme activity and obtained better growth performance compared to the fish fed FO diet(Plucolipid metabolizing enzymes in L-0.15 group were significantly increased compared to those in FO group(P<0.05).Reducing 1%fish oil along with 0.1%lysophospholipids added to the feed could improve the digestion and absorption of nutrients,enhance the activity of liver glycolipid metabolizing enzymes,and thus effectively promote the growth of largemouth bass.

A giant fault-controlled oilfield has been found in the ultra-deep(greater than 6000 m) Ordovician carbonate strata in the northern Tarim Basin. It is of great significance for hydrocarbon accumulation study and oil exploitation to determine the key oil accumulation periods. Based on detailed petrographic analysis, fluid inclusion association(FIA) in calcite samples filling in fractures from 12 wells were analyzed, and key accumulation periods of the strike-slip fault-controlled oilfield was studied by combining oil generation periods of the source rocks, formation periods of the fault and traps, and the fluid inclusion data.(1) There are multiple types of FIA, among them, two types of oil inclusions, the type with yellow fluorescence from the depression area and the type with yellow-green fluorescence from the uplift area with different maturities indicate two oil charging stages.(2) The homogenization temperature of the brine inclusions in FIA is mostly affected by temperature rises, and the minimum temperature of brine inclusions symbiotic with oil inclusions is closer to the reservoir temperature during its forming period.(3) FIA with yellow fluorescence all have homogenization temperatures below 50 ℃, while the FIA with yellow-green fluorescence have homogenization temperatures of 70–90 ℃ tested, suggesting two oil accumulation stages in Middle-Late Caledonian and Late Hercynian.(4) The Middle-Late Ordovician is the key formation period of the strike-slip fault, fracture-cave reservoir and trap there.(5) The oil generation peak of the main source rock of the Lower Cambrian is in the Late Ordovician, and the oil accumulation stage is mainly the Late Ordovician in the depression area, but is mainly the Early Permian in the uplift area. The key oil accumulation period of the strike-slip fault-controlled reservoirs is the Late Caledonian, the depression area has preserved the primary oil reservoirs formed in the Caledonian, while the uplift area has secondary oil r

本试验旨在研究饲料不同糖源对大口黑鲈(Micropterus salmoides)生长性能、糖脂代谢和抗氧化能力的影响。试验以红鱼粉、鸡肉粉和酪蛋白为主要蛋白质源,大豆油和鱼油为主要脂肪源,分别以葡萄糖(Glu组)、蔗糖(Suc组)、糊精(Dex组)、玉米淀粉(CS组)、豌豆淀粉(PS组)和木薯淀粉(TS组)为糖源,配制6种等氮等脂的试验饲料。选择健康、规格均匀的大口黑鲈鱼苗540尾[初始体重(5.01±0.04)g],随机分为6组,分别饲喂对应的6种饲粮,每组3个重复,每个重复30尾鱼。试验期56 d。结果表明:1)Suc组和PS组的增重率和特定生长率显著高于Glu组、CS组和TS组(Plu组、Suc组和Dex组(Plu组、Suc组和Dex组的摄食率显著高于CS组、PS组和TS组(Plu组血清甘油三酯含量显著低于Suc组(Plu组血清葡萄糖含量显著高于Suc组和PS组(Plu组和CS组血清胰岛素含量显著高于其他组(Plu组和PS组(Plu组、PS组和TS组肌糖原含量显著高于Suc组、Dex组和CS组(Plu组、Suc组和TS组(Plu组和CS组(Plu组、Suc组、Dex组和TS组(Plu组和Suc组(Plu组、Suc组和Dex组(Plu组和Suc组(Plu组、Suc组、Dex组和CS组(Plu组肝脏胰岛素受体底物(IRS)mRNA相对表达量显著低于其他组(Plu组、Suc组、Dex组和CS组(P<0.05)。综上所述,大口黑鲈摄食蔗糖可达到与摄食豌豆淀粉相当的生长性能,但饲料利用效率和抗氧化能力较低;与玉米淀粉和木薯淀粉相比,摄食豌豆淀粉更有利于大口黑鲈的生长、饲料效率、抗氧化能力和对糖的利用。

塔里木盆地顺托果勒低隆起顺北4号走滑断裂带是该地区重点勘探目标,中奥陶统碳酸盐岩是主要的含油气层系。断裂活动及伴随断裂活动的断裂流体活动控制了研究区内储层的分布,因此,研究断裂流体的活动特征对勘探工作至关重要。针对研究区顺北4号断裂带内中奥陶统碳酸盐岩裂缝中的方解石进行了岩石学、原位锶同位素、原位稀土元素和U-Pb测年研究。方解石的锶同位素比值为0.708498~0.709177,方解石稀土元素表现出明显的Ce负异常、Eu正异常和高Y/Ho比值。方解石U-Pb测年获得的年龄分别为(433±17)Ma和(449±15)Ma。方解石的原位锶同位素和稀土元素特征说明流体充分继承了碳酸盐岩围岩的特征且经历了高温;U-Pb年龄则说明顺北4号断裂带方解石记录的更可能是与阿尔金造山带挤压造山相关的加里东中期Ⅲ幕运动的断裂流体活动。
