鱼卵

The result suggests PACAP/GHRH has an important role in embryos and larvae, especially in neurula appearance stage.

结果表明，自卵受精后，均有GHRH／PACAP的表达，且在神经胚期表达量增高（约5倍）；提示PACAP在斜带石斑鱼胚胎和仔鱼发育过程中具有重要作用，尤其是神经出现阶段。

"Birds, fish , and amphibians are ""oviparous""."

鸟类、鱼和栖类是"卵生"的动物。

In fact, all things are also following this principle. The bird is oviparous, the mammal is viviparous, the creatures on land breathe with lung and most fishes breathe with gill.

万物就是这样，乌鹊是卵生，哺乳动物是胎生，陆地上的生物用肺呼吸，而大部份的鱼则用鳃呼吸的。

The bird is oviparous, the mammal is viviparous, the creatures on land breathe with lung and most fishes breathe with gill.

万物就是这样，乌鹊是卵生，哺乳动物是胎生，陆地上的生物用肺呼吸，而大部份的鱼则用鳃呼吸。

Serpents in general are oviparous; the adder, an exceptional case, is viviparous: for not all viviparous animals are hair-coated, and some fishes also are viviparous.

大蛇类通常是卵生的；蝰蛇是一个例外，是胎生的：因为并不是所有胎生动物都是有体毛的，一些鱼也是胎生的。

Growth rate increased with higher summer temperatures in sole and to a lesser degree in plaice.

较高的夏季温度，卵鳎的生长速率也会增加，但是鲽鱼的生长程度较低。

Autumn length showed an increasing trend in sole but not in plaice.

卵鳎长度秋季有增加的趋势，鲽鱼没有。

The effects of salinity on the buoyancy hatching and abnormal rate of fertilized eggs of ovate pompano at 10 different salinities ranging from 5.0 to 50.0 were studied. Moreover, the survivorship as well as survival activity index of larvae of T.ovatus at 8 different salinities ranging from 10.0 to 45.0 were also observed.

观察比较了10种不同盐度（5.0~50.0）条件下卵形鲳鲹受精卵的沉浮性、孵化率和畸形率，以及8种不同盐度（10.0~45.0）下仔鱼存活情况及不投饵存活系数（survival activity index，SAI）。

They spawn once every 5 to 7 years and yield about 25% of their body weight in roe.

淡水湖鲟鱼每5到7年产一次卵，产卵量可达其体重的25%。

Test According to marine experts, rhino feetis a non-polluting shallow water, where the shallow tidal flats have a tremendous wealth of fish, shrimp, crabs and shellfish, algae and other micro-organisms, which reared duck grazing provides a natural high-quality food,sea duck is the duck reared with grazing produced, eggs rich in calcium, iodine, zinc, selenium, iron, magnesium, potassium and other trace elements and vitamins needed for a variety of human , amino acids and rich in lecithin, is an ideal food.

据海洋专家检测鉴定，犀牛脚三娘湾是一片无污染的浅海，那里的浅海滩涂上有着极为丰富的鱼、虾、蟹及贝类、藻类等微生物，这为放牧饲养的蛋鸭提供了天然优质的食料，三娘湾海鸭蛋就是这一带放牧饲养的蛋鸭所产，蛋中富含钙、碘、锌、硒、铁、镁、钾等多种微量元素和多种人体所需的维生素、氨基酸及丰富的卵磷脂，是理想的绿色食品。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
