It depends on where you bought it. Except for the place called Tou, you can buy a very small fishing boat (below 10W) certificate for 40,000 yuan! Small fishing boats can basically earn about 20,000 yuan a year. Excluding the cost (oil and coolies), they can earn about 1000 yuan, and the annual oil replenishment can be about 7,000 yuan. Jellyfish's annual income is the biggest income, but there must be a house by the sea to process. Jellyfish make money by luck! Small fishing boats can only fish near the shore, and can't go farther like big fishing boats. Usually they can only catch small crabs according to the season. The income is not big, mainly jellyfish. The state has strict management and unified fishing for jellyfish every year, so it is necessary to have some relevant experience in watching the tide under the net, otherwise it will be over if you miss the tide! My family has two fishing boats. Every year, they just go to the dock and do nothing. Usually, if they spend enough money, they won't play with crabs. Fortunately, fishing boats are replenished with oil every year, about 10 watt, 7,000-8,000 yuan, and 220 horsepower is130,000 a year, hehe! Much better than working at sea! Oil-replenishing fishing boats refer to licensed fishing boats. If there is no certificate, there will be no oil supplement, and some fees will be paid every year. For example, a fishing boat with 220 horsepower has to pay more than 20,000 yuan a year to get fuel supplement. Don't do this industry without sea work experience. The experience of going to sea ranks first, and it is very hard to be a fisherman. Dress like a beggar every day. Although the fishing boat equipment is very advanced now, there are radars, fish detectors and GPS, which means that only large fishing boats can be equipped. Small fishing boats still rely on compasses, and some don't even have compasses because of their experience! In addition to the cost of buying a fishing boat, there are other costs, such as fishing nets, what kind of fishing nets are used to catch anything, not fishing nets, but everything, such as crab cages for catching crabs, trawls for catching shrimps, and houses by the sea. Usually, coolies should be hired, on board 1-2, and also on land when processing jellyfish, otherwise jellyfish will turn into water in a few minutes, the ratio of salt to alum for processing jellyfish and so on. Ha ha! In short, nothing is easy to do!
