Wenzhi Lin, the former assistant researcher of China White Dolphin Reserve, mainly engaged in the research of marine mammal genealogy geography, population genetics and population ecology, and cetacean conservation biology. He arrived in Shenzhen at 4 am on July 2, and immediately went out to sea to observe Brucella whales.
"According to the observation on the morning of July 2, compared with the previous pictures, there is only one Brucella whale in this sea area, which is very active and has a strong willingness to prey. At present, it is healthy and there is little risk of grounding, so there is no need to take emergency measures to guide it to leave. This is a rare inshore activity of Brucella, and the scientific research opportunity is rare. Adsorption identification tools can be used to record the behavior and activity trajectory of Brucella. " He said that according to the information currently available, large cargo ships start and sail slowly and will not pose a threat to life.
But in recent days, many people go out to watch whales, and the speed of boats will interfere with and threaten the activities of whales. It is necessary to manage the gathering of tourists to watch whales on weekends.
Living habits of brucellosis whales
Brucella whales don't fit into large groups. Brucella whales in the North Pacific usually move alone or in groups of 2-3, and 12 is the largest group. Their tidal discharge is about 3~4m high. Usually after 4-5 breaths, do a long dive.
Sometimes you exhale underwater and then come out. At this time, there is almost no tidal foam. It is rare to see them lift their tail leaves before diving. The usual swimming speed is about 2~7km/h, and it can reach 20~25km/h when it is fast, and it can dive to a depth of 300m·m m. Brucella whales are often seen jumping into the water.
