Chapter 200 Fishing
Li Chengxin looked at the place the student was pointing at. There was a group of small fish a little deeper in the puddle.

The small fish is slender and long, the back is blue-gray, and there seem to be long and thin black stripes on the side. The fins and the base of the tail of the small fish are red, which looks very beautiful.It is May, and the stream gushing from the mountains is only ten degrees, very cool.

"It's yarrow, a small fish of the Cyprinidae family. If it's grilled and eaten, its meat is soft. Fish of the Cyprinidae family are more voracious, and it's not difficult to catch. You can use some aquatic worms as bait." Li Chengxin dutifully Introduced.

【Zicheng is really knowledgeable! 】

[Xin Wa'er graduated from Ocean University, and I recognize marine fish, but I know so much about freshwater fish and plants. 】

[I don’t know why, but listening to Zicheng’s introduction, I started to drool...]

"In addition, now is the favorite spawning period of yarrow fish. Once they find clean rocks, they will gather to lay eggs."

As he said that, Li Chengxin picked up a few white stones from the dry place on the bank, and carefully put them into the puddle, where the crocodile swims.

"Wow! I really swam here!"

Amid the students' soft voices of surprise, a small group of yarrow fish branched out and swam toward the white stone that Li Chengxin had put in. Several fish gathered together and clung to the white stone before their eyes.

The belly of a fish keeps turning. Everyone knows that the fish is laying eggs, and there are several male fish gathered nearby. If we continue to describe what they are doing, this chapter will be blocked.

A student found a white stone in the shallows. He picked it up and was about to put the stone into slightly deeper water like Li Chengxin did, but found some light yellow things on the white stone.

When I picked it up, I saw a small pile of round eggs sticking to it.

Li Chengxin took a look and confirmed, "These are the eggs of the yarrow."

The student was stunned: "Wow! It turns out that this is how the fish eggs are attached to the stone!"

Li Chengxin nodded: "These eggs will hatch in about two weeks, but since the water where Yaluo fish spawns is not deep, most of the eggs will be eaten by natural enemies such as birds."

The student nodded knowingly, and carefully put the white stone with fish eggs into the deeper water: "This is a very precious little life. This kind of experience is definitely something that cannot be learned in class."

Another student who was looking for bait couldn't laugh or cry: "We are protecting fish eggs and fishing for food at the same time. It's really contradictory."

Where to find aquatic bugs, all the students present are students of Ocean University, of course they know that the most convenient way is to turn over rocks.

The student who had suggested fishing rolled up his sleeves and turned over a big rock beside the puddle.

"Sure enough, there are a lot of little bugs. No wonder these little fishes gather here."

As soon as the stone was turned over, there were small creatures struggling to get into the small crevices under the big stone, and some swimming with the water. Naturally, a few of them stuck to the stone and were turned out.

【insect!I can not make it……】

[My Lan Lan hasn't touched any bugs this year! 】

[What kind of worms are on the rocks, and the worms in the water also look so scary? 】

The student took the stone to let Li Chengxin identify it.

Li Chengxin naturally has no problem: "This is Bian Yu."

"Bat?" The student who was still folding bracken was taken aback, "There are also aquatic bats here?"

Hearing this illogical question, everyone couldn't help laughing.

Li Chengxin continued: "The flat mayfly is a family of mayflies. The main feature is that all parts of the body are flat. The adult mayfly's wings cannot be folded. It is an ancient and special body structure. It is the most primitive winged insect. .”

When it comes to mayflies, the most famous feature is their "live and die".In fact, this statement is not entirely true.

Mayflies go through four stages in their life: egg, nymph, sub-adult and adult.After mating, mayflies lay their eggs in water, which hatch into nymphs after a period of time.The nymph stage of mayflies is longer, up to several months or more than a year, and can be dormant for up to 4 years, which is the current flat mayfly state.The larvae live underwater all year round, mainly in freshwater lakes or streams, and their food is mainly water grasses, algae and larvae.So, in a way, mayflies are also beneficial insects.

In the nymph stage, mayflies have to undergo more than 20 molts before they grow into sub-adults. After coming out of the water, the sub-adults stay on plants or stones near the water, and after about 24 hours, they molt and finally become adults. .

The lifespan of mayfly adults is very short, ranging from a few hours to as many as 1 to 2 days, and a few can exceed 10 days.Once the mayfly becomes an adult, its mouthparts will degenerate and lose the function of eating.Therefore, the mayfly in the adult stage will be in a state of neither eating nor drinking, and can only rely on the energy accumulated in the body to maintain life. Therefore, the survival time of the mayfly becomes short.

Back to fishing.

"Used as fishing bait, flat flies are an irresistible delicacy for freshwater fish in streams."

This student who loves fishing skillfully grabbed a flat fly, grabbed its tail, and inserted a simple fishing hook between the thorax and abdomen of the flat fly.

Throw the fishing hook into the deep water area of ​​the puddle. In theory, there should be many fish hiding in the deep water area, where they can avoid predators such as birds. The fish will be less vigilant and more likely to bite the hook.

"Huh?" Just after throwing the bait into the water, the student's hand sank, and he lifted the fishing rod again, and there was a small fish flicking its tail on it, "Hey, I haven't prepared myself yet, why did I take the bait?" gone?"

Li Chengxin took the small fish that was carried in mid-air: "This is a juvenile crocodile. Hey, it didn't come up by biting the hook, it means that the hook just caught its gills."

Probably because few people usually come here to fish, other students who went fishing on the other side soon also had harvests, and the bait made of flat flies was also very popular.

For a while, everyone lifted their poles, and almost all the adult fish caught were yalo fish, and the first juvenile fish that was "hooked" was instantly compared.

The internal organs of the yarrow are easily perishable, so the fish must be cut open immediately after being caught.

The third uncle picked up the sickle and cut open the belly of the yarrow fish, quite like killing a chicken with a sledgehammer.Li Chengxin took over the cut open fish and took out the internal organs and gills.

After the repaired fish is cleaned, thin bamboo branches are passed through the gills and out of the mouth to form a string.The bamboo leaves at the end of the bamboo branches prevent the fish from falling. A string of blue-grey and reddish yalo fish looks very beautiful against the background of the bamboo leaves, attracting a few female students who ran away because of catching mayflies and killing fish. Come over and take pictures.

"Wow! This picture has only been seen in comics!"

"It's the first time I know that fish can be so artistically skewered!"
