The most important thing for a trawler is quantity. The bigger the ship and the heavier the tonnage it carries, the more quantity is important.
Deep-sea fishing can target different fish species, but to target a specific fish, you need to understand the ecological habits and activity patterns of the fish species, and choose different fishing nets according to the different fish species and fishing environment.
Trawling is suitable for searching for fish over a large area and generally does not target specific fish. Even if you know that there are many fish of a certain type in this water area, you can stay in this water area for a longer time, but most fishermen will catch fish whenever they can.
Ever since Yu Shengnan realized the limitations of the trawler, he no longer deliberately catches a certain type of fish. To be precise, his perception is still too limited, which limits the performance of the fishing boat, and he has no choice.
"How is it? Are you okay last night?" The next morning, Yu Shengnan got up, washed up, and then went to the deck to check with Zhao Lei.
"It wasn't a lot, but we caught three tunas, yellowfin tuna. The big one weighed about 130 or 140 kilograms, and the smallest one weighed about 50 or 60 kilograms. They're all stored in a separate cold storage."
"Guo Zhuang will prepare the smaller one for everyone to try. It's almost time for our shift change, right? Have a good rest after your shift change."
We also pulled two nets last night, and one of them caught over six tons. Unfortunately, more than half of it was thrown back into the sea, and it was all some miscellaneous fish and marine debris.
It would be fine if the marine debris can be degraded by seawater. However, if it is white garbage that cannot be decomposed naturally by the ocean, then it can only be collected, put on a boat, and brought back to land.
Everyone had a great breakfast. The boss was really generous with the tuna. Although this tuna was a little smaller, only 60 kilograms, it would cost more than 10,000 yuan even at 180 yuan per kilogram. The boss was generous, the crew ate well, and they also looked forward to future welfare benefits.
Yu Shengnan went to the cockpit and took over the driving of the boat, asked Jiao Kegui to eat, and then went back to rest.
However, Yu Shengnan did not let him rest in the captain's bed room. As a doctor, he was more or less a little bit of a germaphobe. Of course, it would be acceptable if a beautiful woman slept in his bed, but he could not accept a rude man.
About eight tons of goods were loaded yesterday during the day and at night. The fish hold of "Chusheng" can hold more than 200 tons. It will take twenty-five or twenty-six days, plus the time for round trip, it will take a month.
Even so, we haven't run too far. If we go further, it will take longer. Of course, there are advantages. The supplies on the ship are enough for a month, but if we stay at sea for too long, we may have to find a suitable supply point for replenishment.
Driving a boat is a very hectic job. The sea ahead is endless and you rarely see a boat at all, but you have to keep an eye on the equipment to prevent any accidents ahead.
Yu Shengnan was looking ahead boredly when suddenly a black dot appeared in front of her, then gradually grew larger, and then dispersed into several black dots. This was not just a black dot, it was clearly a large flock of seabirds.
Fishermen who often go out to sea know that where a large number of seabirds gather, there are usually schools of fish.
Although Yu Shengnan was an unqualified fisherman, she knew this common sense and drove the boat straight over.
As we got closer, we could clearly see the seabirds. Most of them belonged to a single species, ranging in length from 70 to 140 centimeters. They had a hooked bill at the tip, tubular nostrils, long wings, and short tails and legs located at the back of their bodies. The first three toes were fully webbed. Their bills were long and strong, covered in numerous horny plates, with the tip of the upper bill curved downward. Their noses were tubular, and their necks were short. With a wingspan of 3 to 4 meters, they were truly large seabirds. Yu Shengnan recognized this species: the albatross, a common seabird.
Yu Shengnan also saw what was happening underwater: countless sardines clustered tightly together, extending backward in a large spiral.
It is obvious that this is a school of sardines, a school of fish that both makes people happy and annoyed. The happy thing is that sardine schools are generally large schools of fish, and the annoyed thing is that sardines are really cheap.
But no matter how cheap it is, it is still suitable. Even if the whole ship is full of sardines, 200 tons is a big deal. Even if one pound of sardines costs one yuan, Yu Shengnan will make hundreds of thousands of yuan on this trip. This is the remainder after deducting all expenses. What's more, the wholesale price of sardines on land is three or four yuan per pound, which is a big profit for sure.
Looking at the seabirds flying in front, Yu Shengnan drove the boat across and without waiting for any time, she immediately collected the net.
"Get ready to collect the nets, everyone hurry up, and those who are resting should get up to help. We have encountered a school of fish, so be ready to pull in more nets," Yu Shengnan shouted directly to Zhao Lei through the walkie-talkie, asking Zhao Lei to call for help.
Another benefit of a fishing boat encountering a school of fish is that it reduces the crew's workload of sorting, because the large school of fish is concentrated in a single species. When the net bag is opened, it is full of sardines. They can be directly loaded into baskets and moved to the cold storage.
The net simply burst. The net was quite large, so it took a lot longer to haul it in. But Yu Shengnan didn't give them a chance to rest. She unzipped the net and dumped the fish onto the deck. She told them to lower the net again, but he had already started the boat and rushed over while the birds were still visible.
Even though he kept driving the boat after the school of fish, the "Chusheng" only pulled four nets before stopping. Now it had been 10 hours since the fish were discovered, and everyone on the boat had not eaten, but had been working non-stop.
What was satisfying was the harvest. The net was full of sardines. The trawl net equipped with the Chusheng could theoretically hold 15 tons, but usually 10 tons would be full.
Yu Shengnan took into consideration the size of her boat at the time. The fish were interspersed diagonally. The largest net held more than eight tons, and the smallest was more than six tons. The key point was that it was all sardines, with almost no miscellaneous fish.
Today was like several days' work, bringing in thirty tons of fish. We've already recovered all our costs, and every fish we catch is a profit.
"We'll have plenty of sardines for dinner, and then we'll take a collective rest after dinner," Yu Shengnan ordered the crew.
Although the order was given, Yu Shengnan could not rest. The "Chu Sheng" had already chased the school of sardines to the high seas. Although it was no longer chasing the school of fish, it still had to continue operating.
The reason why they gave up the school of sardines was mainly because Yu Shengnan saw a shark.
A large number of sardines gathered and migrated, and sharks, dolphins and whales would not miss this delicious meal. There might even be many large fish following them underwater, but Yu Shengnan did not take the risk. Although he might pull up a few big ones, the damage to the fishing net would be even greater, so he gave up.
