How to catch tuna.
Tuna is a large fish that has a high economic value. Due to the fast swimming speed of tuna, it is not easy for divers to successfully catch them. Here are some things divers need to look out for when catching tuna.
First of all, divers need to have professional skills and experience in catching tuna. They need to be familiar with the habits and behaviour of tuna, as well as dive techniques and catching techniques. At the same time, divers also need to have good physical fitness and endurance, as catching tuna requires long underwater tracking and diving.
Secondly, divers need to choose the right fishing gear when catching tuna. Generally, divers will use tools such as net bags, harpoons, fishing rods, etc., to catch tuna. These tools need to be selected and adjusted for the characteristics of the tuna, such as the mesh size of the net bag, the length of the harpoon, and the bait of the rod.
Thirdly, divers need to be safe when catching tuna. Due to the fast swimming speed of tuna, divers need to be vigilant at all times to avoid being bumped or bitten by tuna. At the same time, divers also need to pay attention to underwater visibility and current conditions to avoid accidents during the capture.
Finally, the tuna caught needs to be handled and transported properly. Generally, tuna is placed in ice water to cool down quickly before being packed and transported. During this process, divers need to take care to maintain the quality and freshness of the tuna and avoid losses during handling and transportation.
In conclusion, divers need to have professional skills and experience when catching tuna, choose the right fishing gear, pay attention to safety and handle transportation. These precautions are taken to ensure the quality and freshness of the tuna caught, as well as to ensure the safety of divers.
