Human bycatch (or human by-catch) is a term for people who are unintentionally caught on film, in photos, or acoustically recorded on equipment used to monitor wildlife or habitats for the purpose of conservation, or environmental law enforcement.
To minimize accidental capture of marine animals, National Oceanic and Atmospheric Administration (NOAA) fisheries developed and tested bycatch reduction devices (BRDs). ). These devices are openings in shrimp trawl nets that allow finfish or other unwanted aquatic animals to escape, while the target species, shrimp, is directed towards the tail bag or cod end of th
Cetacean bycatch (or cetacean by-catch) is the accidental capture of non-target cetaceans such as dolphins, porpoises, and whales by commercial fisheries. [1] Bycatch can be caused by entanglement in fishing nets and lines, or direct capture by hooks or in trawl nets. Cetacean bycatch is increasing in intensity and frequency. [2]
Animals which lack that Ampullae of Lorenzini organ do not display aversive behavior in close proximity to the magnetic field, making this technology selective. When a shark swims through the Earth's magnetic field, electromagnetic induction – a phenomenon which generates voltage in an electrical conductor moving through a magnetic field ...
Some fisheries retain bycatch, rather than throwing the fish back into the ocean. Sometimes bycatch is sorted and sold as food, [34] especially in Asia, Africa and Latin America, where cost of labour is cheaper. Bycatch can also be sold in frozen bags as "assorted seafood" or "seafood medley" at cheaper prices.
Tracking devices can locate items using Bluetooth technology. This technology sends an encrypted, anonymized SOS-like signal between mobile devices nearby to help pinpoint the location of whatever ...
A "SMART" drum line is based on the traditional drum line design, but it includes technology that can alert rangers to the capture of marine life, who can then attend the device if sea conditions permit. In Reunion, fishermen usually attend the drum lines within 90 minutes of an alert and 90 per cent of animals caught on the hooks survive. [53]
Technology can enhance memory if it is used consistently with principles that help us remember. Thoughtfully taking pictures or videos at opportune moments can orient us to what is interesting and ...
