Chapter 1857 Golden Koi

At first, they felt that there was no vegetation on both sides of this big river, but after they walked more than a hundred meters, they began to find some vegetation.

‘Dad, you see that there is already vegetation here, which means that there must be the eighth amethyst gemstone we are looking for. Feifei looked at Zhao Zhongyao happily and said.

After hearing Feifei's words, Zhao Zhongyao also said, 'Of course, as long as there is life, there will be the amethyst gemstone we are looking for. '

Tiantian also seemed very happy at this time. After all, they all knew now that as long as they could see signs of life, it meant that there would definitely be the amethyst gem they were looking for in this place.

After all, in the solar system, apart from life on Earth, there is no life on other planets. If it is alive, it must be the result of the magic power produced by the amethyst gemstone here.

'Dad, let's move forward quickly! Maybe we'll see an amethyst gem anytime soon. ’ Said the same every day.

'Okay, let's move on! After Zhao Zhongyao finished speaking, he took his son and daughter and continued to walk forward.

But after they walked a certain distance, Feifei suddenly pointed into the water and said, 'Dad, look quickly, there are many big fish in the water. '

After hearing Feifei's words, Zhao Zhongyao and Tiantian also looked into the river together. They were both very surprised when they saw it.

Because at this time, they all saw some very large golden fish swimming around in the water.

These fish are all one or two meters long, so they are really big fish.

‘Dad, what kind of fish is this, how can it be golden. ’ Feifei looked at these big fish in the water in puzzlement and asked.

'yes! What kind of fish are these fish and how can they be golden. ’ Tiantian also looked at the fish in the water with a puzzled expression.

After hearing what his son and daughter said, Zhao Zhongyao stared at the water for a while, and then said with a smile, "These fish should be giant golden carp. We are very lucky to be able to see these huge carp . '

'Dad, what do you mean by that, can these golden carp bring us good luck! ’ After hearing what Dad said, Feifei couldn’t understand it.

'It should be like this! Zhao Zhongyao said again.

‘Dad, do you know something about the golden carp? Tell us about it. Said looking at Zhao Zhongyao every day.

'Okay, let me tell you about the golden carp! Zhao Zhongyao said so.

In fact, the fish we see now is the golden koi. The whole body of this carp is only monochromatic golden yellow, the scales are arranged neatly, and the whole body emits a golden-like crystal light. When the water temperature is higher in summer, the color of the gold will change to a dark golden yellow.

The carp whose whole body is golden and monochromatic is called golden koi, which requires a strong luster on the head. In addition, the tips of the scales are all shiny, which is called "covered scales" and has the same "outline" shape as light yellow. Representatives of this kind of koi are gold, white gold, gray gold and so on.

Like goldfish, golden carps do not have strict requirements on water temperature and water quality, and the turbidity range of living water is 2-30 degrees Celsius. Although it has strong adaptability to the environment, it has the weakness of being unable to resist sudden changes in water temperature.

Such as long-term artificial breeding, the water turbidity rises and falls by 2-3 degrees Celsius and can be tolerated. When the temperature drops or rises more than 2-3 degrees Celsius, the fish is prone to disease. When the temperature rises to 7-8 degrees Celsius, the fish crawls on the bottom of the water. If there is no food or food, if the temperature mutation is too large, it will even die immediately.

The most suitable water turbidity for life is 20-25 degrees Celsius. In water of this temperature, koi swim actively, have a strong appetite, have a strong physique and bright colors. It is more ideal to control the water temperature that is most suitable for the growth of koi, so that the fish can have a comfortable environment and grow rapidly.

Golden carps rely on their gills to absorb oxygen dissolved in water, and send oxygen to the fish body to combine with the absorbed food nutrients to generate energy to maintain life. Therefore, whether there is sufficient oxygen in the water is the key to raising fish well. The amount of oxygen required for a kilogram of body weight per hour is 35 mg/L when the water temperature is 5-6 degrees Celsius, which proves that the higher the water temperature, the greater the oxygen consumption.

Zhao Zhongyao told the two children about this golden koi. After the two children heard it, they knew something about this kind of carp.

'Dad, so the water temperature here is relatively high. ’ Said Feifei.

'yes! The water temperature here should be relatively high, otherwise, it would not be suitable for this kind of golden carp to survive. Zhao Zhongyao said so.

‘Dad, I don’t know where the amethyst gem we are looking for is. It's impossible for these golden carp to help us find the amethyst gem! ’ said Tian Tian.

After hearing what Tiantian said, Zhao Zhongyao smiled and said, Haha, it’s hard to say, maybe we can know where the amethyst gem is through these golden carp. '

'Dad, is this really the case! Then how can we know where the amethyst gemstone is. ’ Feifei asked again.

'Let's just watch where these golden carps swim! If we follow them, we should almost be able to find the eighth amethyst gem. Zhao Zhongyao said so.

'Okay, then let's follow these golden carps and move on! ’ Feifei said again.

After speaking, they followed the carp and continued to move forward.

These golden carps seemed to be leading the way for Zhao Zhongyao and the others, so they swam in the water unhurriedly.

Zhao Zhongyao, Feifei and Tiantian have been walking forward with this group of big fish

with. They soon reached a place with dense vegetation.

After arriving at this place, the river in front suddenly became very wide, as if flowing into a huge lake.

'Dad, look, there is a huge lake ahead. ’ Feifei looked at the wide river ahead and said.

'That's right, this river seems to have poured into this huge lake. Zhao Zhongyao said the same.

It was here that these golden carps came to the junction between the river and the lake.

After arriving at this place, Zhao Zhongyao was surprised to see that at the junction between the river and the lake, there was a long and narrow boulder that separated the river from the lake. At this point the waters of the river converged and formed a pool.

In the middle of this boulder, there is a gap like a gate. All the river water pours into the lake from this gap.

If these big fish want to enter the lake, they have to swim into the lake from the gap in the middle of the boulder.
