Lu Huaping explained to the caretaker of the communication room, and then took a few people to his dormitory.

In the end, it is a graduate dormitory, compared to Xu Yi's dormitory, this room is really not big, but after all, it is only a room for two people, so the relative single area is much larger than Xu Yi's.

The girl's room is very tidy, but the other bed is empty, and no one lives in it at all, but I don't know if Lu Huaping has not arranged a roommate or her roommate does not live in the dormitory at all.

Although undergraduates can get married now, there are not many people who actually get married during school, but at the graduate level, there are quite a lot of marriages, especially medical schools.

After all, normally speaking, there are five years of undergraduate in medical schools, and only four years in other schools, and graduation is one year later than other schools, most people graduate at the age of 23, and when they graduate from medical schools, they have to be 24 years old.

If you really wait until you graduate in three years, you have to be twenty-seven years old, which is already the age of Bensan, and it is not too much to even take the exam for three years or two years.

This man is fine, but this woman's statement of thirty tofu scum is really reassuring, not to mention that pregnancy and childbirth before the age of twenty-eight is the best time period, so if both men and women are graduate students, many of them basically rent a house off campus after getting a certificate, and even take a year or two off school to go home to give birth to a child.

Although there are no furnishings in the room, there are fourteen or fifteen fish tanks on the side of the floor.

Xu Yi took a look, there are only two kinds of fish in this fish tank, most of the fish tanks have a kind of red fish more than two inches long, and some of them are some small yellow fish more than an inch long with black striped spots, thinking that this is Yan Peimin's so-called zebrafish.

All the fish tanks are plugged in with aerators, gurgling and bubbling, which also makes the room full of a faint smell of water vapor, which can only be said to be fortunate to be this season, if it is winter, I am afraid that the room will be too humid.

Sure enough, he watched Yan Peimin walk to the fish tanks with small yellow fish placed against the wall, squatted down, squinted his eyes and carefully inspected the fish tank with only two fish in it.

A few people were curious, and followed Yan Peimin to squat on the ground and watch him busy there. At this time, Xu Yi saw clearly that the pebbles under the fish tank were covered with a layer of pale yellow fish eggs that were slightly larger than the tip of a needle.

"This is the zebrafish eggs, why are they so small?" The number of eggs in the tank is not very large, about sixty or seventy.

"yes, hehe, small enough. This zebrafish can lay hundreds of eggs at a time if it is kept for a few more months, but this first spawn can lay so many eggs. ”

Hu Yifei watched Yan Peimin take a small net and fish the two fish in the fish tank to the next fish tank, and asked, "Fourth, what are you doing with the big fish?"

"Look at the fish's belly is deflated, obviously the ovulation is over, this has to be fished out quickly. ”

"Can't you do it if you don't fish?"

Yan Peimin smiled, pointed to one of the two fish that he had just fished out and said: "This fish is the same as goldfish, they all like to eat fish eggs, if this big fish wants to be put inside, the eggs should be eaten, and if you put it inside, if you are frightened by moving this big fish, there is a good chance that most of the fish eggs will be wasted." ”

Then, Yan Peimin stretched out the net bag into a fish tank next to him, fished out all the six small fish in it, held the net bag, turned his head and asked Lu Huaping: "Senior Sister Lu, do you have a garbage bag here, give me one." ”

"Yes" said Lu Huaping, found a garbage bag and handed it to Yan Peimin.

"Fourth, wait, what are you doing here?" Xu Yi asked in surprise as Yan Peimin held the fish he fished out and was about to dump it into the garbage bag.

"These are the third generation of fish, I'm just afraid of what happens, so I brought a few pairs back, and now the fifth generation of fish eggs are available, this can naturally be eliminated, and then raising it is also a waste of space. Wait for a few days, the fourth generation of those fish tanks will also have to eliminate most of them, leaving a few pairs just in case, this is fished out, just pour out the water, and save having to bring a tank of water back. Yan Peimin explained.

"Don't throw it away, it's cruel. This little fish is very beautiful, put it in the fish tank for me to take home and play with when I go back at night. When Xu Yi heard him say this, he couldn't help but have a thought in his heart.

"Why are you raising this thing, this fish has a short lifespan, and it will hang up after two or three years, you don't feel distressed, and besides, this thing is a genetically modified skin cancer model, in order to keep the traits all are inbred and married, as the number of generations increases, the resistance will be lower and lower, and the breeding conditions will be higher and higher, and it is not easy to feed at all." If you like this thing, go to the market and buy it, those fish are specially cultivated ornamental varieties are beautiful, and the price is not expensive, and it is better to feed than this. ”

"Hehe, no matter how cheap it is, doesn't it cost money, I'll take it first, and then don't people say that it's difficult to raise fish, if I can feed your genetically modified goods, I can still raise the fish on the market." Besides, this thing itself is genetically modified, and I don't feel distressed if I really raise it to death. I'm raising it here, in case you can't raise it here, I also have an emergency there. ”

Yan Peimin thought about it, and directly poured the fish back into the fish tank. "That's right, I'll put it back in the fish tank first, and then you bring it back with the fish tank at night, you can use this fish tank, this is all a breeding base, and I have enough for these few." ”

Xu Yi smiled bitterly, "This is not good. ”

"It's okay, the pharmaceutical factory is rich, and I don't care about these broken fish tanks at all, it is said that Hu Peel has done a few projects in their pharmaceutical factory, and they have taken more than millions, and they have taken this money, and the work is all done by our senior brothers and sisters, what is it for me to take a few broken fish tanks." Seriously, when the raising is finished, it is enough for me to carry one back for him, and I may even take a plastic bag for him to fill the fish over, this thing is dead, it is too tiring to carry it back and forth, it is better to throw it directly into the garbage heap to save effort. ”

"Yes, Xiao Xu doesn't have to be polite, this thing is not ready to be asked, this thing is just a few glass plates glued together, if you want to run for this again, hundreds of miles down, this is not enough for oil money." Lu Huaping also said with a smile.

Yan Peimin carefully removed the aerators and heating rods of several fish tanks, put them all into a big box next to him, handed them to Liu Liping, and pointed to a few fish tanks. "Let's take these six fish tanks in two trips, and this one has fish eggs, I'll move them next time." ”

After that, the three of them made two trips and brought back several fish tanks.

After returning to the dormitory, Yan Peimin put the aerator and heating rod in the house, and squatted there and smirked.

This can save a lot of trouble, if you calculate it, you will be able to make a difference at the beginning of August, and you can still take Liu Liping out for a leisurely ride.

"Fourth, what do you eat with this thing?" Xu Yi asked.

"Just get some small fish feed, and give you a few packs, anyway, I have a lot of them here - it's all at public expense, and you don't need to use it in vain." Go back and put it in a dry place, just feed a little a day, this thing is not much to eat. With that, Yan Peimin took a few small packets of fish feed and threw them to Xu Yi.

Xu Yi took the fish feed and put it next to him, and secretly wrote down all these points.

"But remember to be like me, spread a layer of pebbles or nylon nets under the fish tank, and the big fish will quickly fish out after laying the eggs, otherwise the eggs will be eaten by the big fish." ”

"How can this thing tell the difference between male and female?"

"Like this kind of fish has a slender body, large fins, yellowish body color, brownish yellow anal fins, and significant stripes are male fish, this kind of body is relatively wide, the body color is lighter, blue, and the anal fin is pale yellow is the female, especially this kind of fish roe can be seen at a glance, this belly is so big, you will not be mistaken. Yan Peimin pointed to the small fish in the fish tank and explained to Xu Yi.

"If you can really feed it, don't worry too much if you see a small fish born, with chronic ulcers or nodules on your body, this is skin cancer, if you don't die and raise the disease yourself, the fish will not live long if it is sick." With the increase of the number of generations, the incidence of this small fish will gradually increase, and theoretically if it reaches the sixth generation or more, at least the incidence of this fish can reach about 7%. As for fish diseases, you can just check it on the Internet. ”

"What is that thing for?"

"Hu Pap skin to test new drugs for others, to use this kind of fish, but in the future to expand the breeding, relying on my raising is not enough, a batch of real yàn has to be dozens or hundreds, a project to do, I don't know how many fish to use, this cost is much lower than mice, and the genes of this thing and some genes of people are more similar, so many pharmaceutical companies have switched to this, do not use mice. ”

"Then you're the fifth generation?" Xu Yi asked, pointing to the fish eggs.

"Yes, I just don't know what the hatching rate is, the hatching rate of this inbred line is not high, this is the most worrying thing, I can have a sixty or seventy percent I will burn high incense. ”

"Are you in time?"

"In time, this fish will be sexually mature in three months, and if it spawns in August, it will be the sixth generation, and I can also make errands, I hope this bastard won't make trouble for me again, I still have to take good classes in the first two years." Yan Peimin said hatefully, this resentment is really not light.

"These two big-bellied ones have fish roe, if you are willing to raise so much, just wait for them to really spawn, make a small fish tank alone, and then get a male to go in, wait for the spawning, fish out the big fish, and the water temperature is controlled at about 25 to 30 degrees, so that they can hatch in two or three days. ”

Xu Yi grabbed a bag of feed and asked, "What do you feed the little fish, do you also feed this feed?"
