Chapter 1678: Golden Koi

The first thousand eight hundred and fifty-seven chapters golden koi
At first, they felt that there was no vegetation on both sides of this big river, but after they walked more than 100 meters, they began to find some vegetation.
‘Dad, you see there is already vegetation here, which means that there must be the eighth amethyst gem 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 is the amethyst gem we are looking for. ’
Tiantian also seemed very happy at this time. After all, they all know now that as long as they can see the signs of life, it means that this place will definitely have the amethyst gem they are looking for.
After all, in the solar system, there is no life on other planets except for life on the earth. If there is life, it must be the result of the magical power produced by the amethyst gem here.
‘Dad, let’s move forward quickly! Maybe we can see amethyst gems soon. ’Said the same every day.
‘Okay, let’s move forward quickly! After Zhao Zhongyao finished speaking, he took his son and daughter to continue walking forward.
But they walked some distance again, and Feifei suddenly pointed to the water and said, ‘Dad, look at it, there are a lot of big fish in the water. ’
After hearing Feifei's words, Zhao Zhongyao and Tian Tian looked into the river water together. When they saw it, they were both very surprised.
Because at this time, they all saw some very big golden fish swimming around in the water.
These fish are one or two meters long, they are really big fish.
‘Dad, what kind of fish is this, how can it be golden. Feifei looked at the big fishes in the water incomprehensibly and asked.
'Yes! What kind of fish are these fish and how can they be golden? Every day, he 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 carps. We are lucky to be able to see these giant carps. . ’
‘Dad, what do you mean by this, can these golden carps make us lucky! Feifei didn't understand what his father said.
‘It should be like this almost! Zhao Zhongyao said again.
‘Dad, do you know something about golden carp, you might as well tell us about it. "Looking at Zhao Zhongyao every day, he said.
‘Okay, let me talk about the golden carp! Said Zhao Zhongyao.
In fact, the fish we see now is the golden koi. The whole body of this carp is only single-color golden, the scales are arranged neatly, and the whole body emits a brilliant crystal light like gold. When the water temperature is high in summer, the color of gold will turn into dark golden yellow.
The carp whose whole body is golden monochromatic is called golden koi, which requires strong gloss on the head, and the apex of the scales is shiny, which is called "covered scales" and has a "gangme" shape like light yellow. The representatives of this kind of koi are gold, white gold, gray gold and so on.
Like goldfish, golden carp does not have strict requirements on water temperature and water quality. The water turbidity range of life is 2-30 degrees Celsius. Although it has strong adaptability to the environment, it has the weakness of not being able to resist sudden changes in water temperature.
Such as long-term artificial rearing, the water turbidity rises and falls at 2-3 degrees Celsius and it can be tolerated. When the temperature drops or rises by more than 2-3 degrees Celsius, the fish are prone to get sick. When the temperature rises and falls to 7-8 degrees Celsius, the fish crawls under the water. If you don’t eat, if the temperature changes to a moderately large amplitude, you will even die immediately.
The most suitable water for life is 20-25 degrees Celsius. In the water of this temperature, the koi swims actively, the appetite is strong, the physique is strong, and the colors are bright. 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 quickly.
Golden carp lives in water by relying on its gills to absorb oxygen dissolved in the water, and send oxygen to the fish body to combine with the absorbed food nutrients to produce energy to maintain life. Therefore, whether there is sufficient oxygen in the water is the key to good fish. The amount of oxygen required per kilogram of body weight per hour is 35 milligrams liters at a water temperature of 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 listened, they knew something about this carp.
‘Dad, that said, the water temperature here is higher. Said Feifei.
'Yes! The water temperature here should be relatively high, otherwise, it would not be suitable for this golden carp to survive. Said Zhao Zhongyao.
‘Dad, the amethyst gem we are looking for doesn’t know where it is. It is impossible for these golden carps to help us find amethyst gems! ’Said this every day.
After hearing what Tiantian said, Zhao Zhongyao smiled and said, ‘haha, it’s hard to say, maybe we can know where the amethyst gems are through these golden carps. ’
‘Dad, is that really the case! Then how can we know where the amethyst gem is? Feifei asked again.
‘Let’s watch where these golden carps swim! We follow them and we should be able to find the eighth amethyst gem. Said Zhao Zhongyao.
‘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 Zhao Zhongyao and the others, and they just swam in the water unhurriedly.
Zhao Zhongyao and Feifei have been following this group of big fishes every day. They soon reached a 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 in front of you. Feifei looked at the wide river in front and said.
‘Yes, this river seems to have poured into this huge lake. Zhao Zhongyao said so too.
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 and the lake. The river water gathers together in this place, forming a puddle.
In the middle of this huge rock, there is a gap like a gate. All the river water is injected into the lake from this gap.
If these big fish want to enter the lake water, they have to swim into the lake from the gap in the middle of the boulder.
