乐生活Let me make a summary.
1. On March 12, 2019, microblogger A released a 7-second video, as shown in Figure 1. Subsequently, I commented on the microblog forwarded by blogger H in screenshots, and there were subsequent related replies, as shown in Figure 2.
2. On April 22, 2019, blogger A released another 37-second video, as shown in Figure 3. I commented on the microblog forwarded by blogger H in a screenshot on April 23, as shown in Figure 4.
3. I found a report published in "National Geographic" on April 27, 2018, as shown in Figure 5. The title is "Shocking Video Shows Impacts of Controversial Fishing Method" (Conservation groups have released footage of sharks, dolphins, and other animals accepting idental caught in California’s driftnet fishery.). The opening section has a longer video, which contains the above 7-second video and 37-second video. Video. The report mentions that the protection group that released the video said that the video was shot from December 2016 to December 2017. The longer video was quoted from Instagram’s blogger "paulnicklen" and clicked to show that the relevant blog posts were published on April 12, 2018, as shown in Figure 6.
4. Based on the relevant reports and blogs mentioned in Point 3, I personally believe that it is basically possible to determine that the relevant video content reflects California/Oregon Drift Gillnet Fishery in the United States. An introduction to the fishery can be found on the NOAA FISHERIES website in the United States, as shown in Figure 7. In the Fishery Description column, Target species are Swordfish and common thresher shark; Other commercially landed species are Mako shark, opah, and tunas (albacore, bluefin, yellowfin); and Bycatch and Incidental takes. Yes, the target species of the fishery are swordfish and longtail shark, and other economic species include mackerel shark, spotted moonfish and tuna (albacore, bluefin and yellowfin tuna). They also hunt blue sharks and tippers, and accidentally catch whales, finfoot and turtles. Figure 8 (from NOAA FISHERIES) shows the "Large Mesh Drift Gillnet" in the diagram.
5. California’s Senate Bill No. 1017 bill for this fishery is another matter, as shown in Figure 9.
6. Then we can take a look at the related microblogs and comments of bloggers A and H. Otherwise, "shocked, American fishermen actually killed long-tailed sharks and cut shark fins alive!" Or "American swordfish trade is not clean in any case!" Well, no business, no killing…
