In particular, sea turtles can be caught when bottom trawling is used by the commercial shrimp fishing industry. In order to catch shrimp, a fine meshed trawl net is needed. This results in large amounts of other marine organisms being also caught as bycatch. When a turtle gets caught or entangled in a trawl net, it becomes trapped and is ...
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
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.
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]
Acoustic harassment and acoustic deterrents are technologies used to keep animals [1] and in some cases humans away from an area. Applications of the technology are used to keep marine mammals away from aquaculture facilities and to keep birds away from certain areas (for instance in the vicinity of airports and blueberry fields).
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 ...
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 ...
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.
