Chapter 95

the next day.

Chen Mo looked at the bank balance and transferred another 5 yuan to Cheng Tang.

The day before yesterday, the balance of the bank account was less than 20, and with the WeChat wallet, 20 was transferred to Cheng Tang.

Yesterday's water spinach sold for 18.31 yuan.

Now, the bank balance is 13.69 yuan, and the WeChat wallet still has 1.3 yuan.

On the other side of the farm, there are 31 greenhouses of water spinach.You can also earn 10,000+.

The drainage channel of the fish pond will not start until the next year, and then harvesting a crop of water spinach should be enough.

After breakfast, Chen Mo looked at the white striped fish eggs in the fish tank. The water temperature was 23 degrees, and the fish eggs were already visible with black dots, probably the eyes of the fish.It's so small that you have to look closely to see it.

It is estimated that it can hatch tomorrow.

Chen Mo mixed some high-protein eel feed to supplement Bai Tiao's nutrition, and then fed it with stream grouper.The creek grouper has not laid eggs yet, and I don’t know if they can lay eggs on their own.

After feeding the fish, Chen Mo drove to Yuxi Town, filled the tank with dozens of liters of diesel oil, and came to the feed store.

"Buying feed?" Lin Sheng was in the store and asked when he saw Chen Mo coming in.

Chen Mo said 'hmm': "Take two bags of feed for the brook grouper."

"Which one do you want?"

"Which one is better?"

Lin Sheng introduced two kinds to Chen Mo, one is yeast high-protein feed, 400 yuan per bag, 1 kg.

There is also fermented corn gluten meal, 260 yuan per bag, 1 kilograms.

"The brook grouper uses carp feed?" Chen Mo asked.

Lin Sheng said 'hmm': "My third brother raises creek groupers and uses 260 yuan of feed."

"Where's the eel feed?" Chen Mo asked.

"Eel feed is mainly used to feed fry. Eel feed is expensive. If eel feed is used all the time, the brook grouper raised will be so expensive."

The eel feed I bought before cost 20 kilograms and cost more than 400 yuan.

Chen Mo smiled and nodded, taking two bags worth 260 yuan, one bag worth 400 yuan, and another bag of eel feed.

On the way back, Master Su called: "I arrived at your house, but I didn't see you."

"I'm outside, I'll be right back." Chen Mo said.

Master Su brought a measuring tape, and Chen Mo measured the total length of the ditch with him, and then calculated the area of ​​the wall to be built...

One morning, Master Su calculated the price. The quotation for the entire drainage channel was 33 yuan, all-inclusive.The pipes of the fish pond (drainage outlet, overflow outlet, drainage gate), the drainage channel with 18 bricks on both sides, and the bottom of the drainage channel are hardened.If the drainage channel needs to be installed with a trench cover, add another 2.5.

Polymer trench covers are sold on JD.com and Taobao, costing tens of dollars each.Buying in bulk can be even cheaper.

In other words, the total price is 35.5 yuan.

"Which materials need to be purchased in advance?" Chen Mo asked.

"Trench covers. The quantity required here is relatively large, so you have to place an order in advance. There are polymer covers and steel trench covers, and the prices are about the same." Master Su thought for a while and said: "Reinforced trench covers should be A better deal.”

"Then use a reinforced trench cover." Chen Mo said.

"This also needs to be booked in advance."

Chen Mo and Master Su went to the aluminum alloy door and window shop in the town and customized the cover.

Without a cover, the ditches are inconvenient in the fish pond area.Just a cover, without spending too much money.

After selecting the specifications of the cover plate, the total cost of the project has been determined, which is 36 yuan, all inclusive.

After returning, he signed a contract with Master Su and paid him 13 first.The money was used as a deposit for the purchase of items, and after the year the fire bricks, sandstone and cement were delivered, he would be paid another 15.The rest of the money will be paid in one lump sum upon completion.

After a few days of busy work, all the drains in the fish pond were dug.

Then nothing will happen.

All the white striped fish in the fish box and tank have hatched, and there are many small fish flowers inside, a little bit big, and their bodies are still transparent.

Chen Mo picked out the big white stripes in the fish box and fish tank, threw a catty and scraped the fish tank with a knife.

River grouper, the water temperature is 25 degrees Celsius, the female fish has a bulging belly, but it just doesn't lay eggs.Two more died this morning, with fish eggs in their bellies.Chen Mo dissected the brook grouper, took out the fish roe from its belly, then found a fully developed male fish, pushed the sides of the fish, squeezed out the milk, stirred the roe in the milk, and stood still for a while. Put them into a 100-mesh nylon cage.

"Has the grouper spawned?" Lin Feng sent a message.

Chen Mo called Lin Feng and said, "I also said to call you."

"The grouper hasn't spawned yet?"

"No. Two of them died this morning, and the belly of the fish was full of eggs." Chen Mo said, "I took the eggs out of the belly of the fish and artificially inseminated them."

"Breeding brook groupers in a box is difficult to spawn naturally. I have bred brook groupers in fish ponds before, and there are fish eggs, but they just don't spawn. In the end, they were injected with oxytocin, and a large number of broodstock died... ..." Lin Feng said: "Push out the fish eggs manually. In fact, the best way is to directly kill the fish to get the eggs..."

"I'm a bit reluctant to kill fish to get eggs."

Lin Feng smiled: "Then push. It's just that the number of fish eggs taken out is less. Do you want to help?"

"Are you free?"

"available."

"That's fine."

Chen Mo went to get a soup bowl, washed it, and tried squeezing it himself.

For one fish, more than [-] fish eggs are squeezed out.

The two fish that died in the morning were even smaller in size, each weighing 90 grams, and there were about 100 fish eggs.There are too few eggs.

There is another one weighing 136 grams, with more than 300 fish eggs produced.

And Chen Mo found a set of data on the Internet, saying that 140 grams of brook grouper can spawn three to four thousand eggs at a time.

Chen Mo squeezed in several fish in succession. The smallest ones weighed more than 80 grams, and the largest ones should have weighed 150 grams.There are still very few fish eggs squeezed out.

I don’t know if his technique was wrong, but Chen Mo squeezed in a few fish, but there were very few fish eggs, only forty or so at most.

While sitting and smoking a cigarette, Lin Feng drove over in his car.

Chen Mo got up and handed Lin Feng a cigarette: "I squeezed some just now, one fish, only squeezed out dozens of fish eggs."

"Artificially induced labor will lay less eggs. Naturally reproduced ones will lay more eggs." Lin Feng lit a cigarette and said: "The fish like the creek grouper are very strange, and artificial breeding is very difficult. There are bionic ponds over there. Reproduce naturally.”

"How many seedlings can you breed in a year?"

"Not many. I was bored during the epidemic years, so I started trying to breed brook groupers... In the most year, 1 to [-] were bred. Unlucky, there were more than [-]."

"How many creek groupers do you have there?"

"There should be [-] to [-] fish. There is a big pond under the flowing pool, more than an acre, and brook grouper and peach blossom fish are raised in it."

"Is the market for brook grouper big?"

"It mainly depends on the price. The wholesale price of about 2 taels of creek grouper here is 70 yuan, and the supply exceeds demand. The retail price is 110 yuan per catty, and occasionally I can sell some." Lin Feng said: "The creek grouper, The bigger it is, the more expensive it is. For people weighing more than half a catty, a fish costs hundreds or even thousands of yuan." Large creek groupers are mainly bought and kept in aquariums.However, large creek groupers are mainly used as broodstock...

"2 taels, how long will it take?"

"One and a half to two years."

Stream grouper, about one or two a year.Stream grouper also depends on genetics. The same species is raised in a pond, and some of them can grow to 2 taels a year, or even more than 2 taels.But there are very few brook groupers like this...

90.00% of the river groupers are found, which is about one or two a year.

Of course, there are many factors that affect the growth of brook grouper, such as environment, climate, feed and so on.These are just the data obtained by Lin Xinhai. He uses medium-to-high carp protein feed for brook grouper, which is the kind that costs more than 5000 yuan per ton.
