Application of new technologies has
allowed governments to collect more data on fish stocks, better monitor, enforce and evaluate the environmental impacts of fisheries activities and improve the effectiveness of policies to sustainably manage fisheries
. To this end, there are many recent technological developments.
What are some technologies used in the fishing industry?
Key innovations in fisheries include the development of
hooks and boats, multifilament nets, echolocation and the diesel engine
, to name a few.
What is advanced fishing technology?
Advanced fish-finding tools such as
GPS satellite navigation and acoustic cameras
facilitate a steady improvement in fishing vessels’ capacity to catch fish, which the researchers refer to as “technological creep.”
How do destructive fishing practices affect the coral reef?
Unsustainable Fishing
55% of the world’s coral reefs are affected by overfishing.
When fish populations decline, particularly those that feed on algae, algae can grow unchecked, eventually smothering corals
.
What is aquaculture and why is it important?
Aquaculture is
breeding, raising, and harvesting fish, shellfish, and aquatic plants
. Basically, it’s farming in water. U.S. aquaculture is an environmentally responsible source of food and commercial products, helps to create healthier habitats, and is used to rebuild stocks of threatened or endangered species.
How can technology be used to reduce overfishing?
LED lights attached to fishing nets can attract the right catch and guide non-targeted species to safety
. This saves fishermen time and helps to avoid what’s known as bycatch – other fish or marine life that inadvertently gets caught in nets, including turtles, dolphins and juvenile fish.
Are tools technology?
In 1937, the American sociologist Read Bain wrote that “
technology includes all tools, machines, utensils, weapons, instruments, housing, clothing, communicating and transporting devices and the skills by which we produce and use them
.” Bain’s definition remains common among scholars today, especially social scientists …
What are the problems faced by fishing industry?
- Overfishing. This term refers to the practice of catching fish faster than they are able to reproduce. …
- Bycatch. …
- Damage to the ocean floor. …
- Managing Fishing. …
- Illegal Fishing.
What is the name of modern hatchery technology mostly used in fish culture?
Artificial fertilisation
facilitates selective breeding programs which aim to improve production characteristics such as growth rate, disease resistance, survival, colour, increased fecundity and/or lower age of maturation.
Are advanced technologies beneficial to capture fisheries?
Technical advances have generally led to more efficient and economical fishing operations
, reduction of the physical labour required per unit of output and improved access to resources.
Can fishing be automated?
Automatic control systems can control quality of fish and fish products
. Automated systems receive, freeze, sort, cut, wash, salt, dry, smoke, press, cool, package and store fish and fish products. Modern technological tools are equipped with automatic control systems.
How does commercial fishing affect marine life?
DEGRADED ECOSYSTEMS
When too many fish are taken out of the ocean
it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals
.
How is fishing a threat to coral reefs?
Blast fishing (i.e., using explosives to kill fish) can cause physical damage to corals as well
. Coral harvesting for the aquarium trade, jewelry, and curios can lead to over-harvesting of specific species, destruction of reef habitat, and reduced biodiversity.
What are the 3 main threats to the Great Barrier reef?
- Coral Bleaching. The Reef has suffered three mass coral bleaching events in just five years due to heat stress caused by climate change.
- Water quality. …
- Crown of Thorns Starfish. …
- Coastal development.
What are the different fishery tools and equipment needed in fish farming?
- 1 Fingerling seine. …
- 2 Fingerling suspension net. …
- 3 Gillnet seine. …
- 4 Screens on water control structures. …
- 5 Harvesting bagnet on gates. …
- 6 Cast net.
What is the difference between fish farming and aquaculture?
Distinction between fishing and aquaculture
Fishing is the harvesting of already existing populations of fish and other aquatic animals.
(Seaweed harvesting is a separate activity.) Aquaculture is the purposeful cultivation and subsequent harvesting of both freshwater and marine aquatic plants and animals.
What means aquaponics?
Aquaponics is
a cooperation between plants and fish
and the term originates from the two words aquaculture (the growing of fish in a closed environment) and hydroponics (the growing of plants usually in a soil-less environment). Aquaponic systems come in various sizes from small indoor units to large commercial units.
How do we monitor overfishing?
High technology applied to fishing techniques
Electronic monitoring (EM) entails onboard video cameras, GPS (location tagging), and sensors to automatically track catches 24/7 on fishing vessels
. It replaces a single observer noting in writing what species are caught and when.
How can fishing be done sustainably?
- Practice Carbon-conscious Fishing.
- Use Lead-free Tackle.
- Practice Catch and Release, Unless you Hook an Invasive Species.
- Pack Out Everything You Pack In.
- When You Keep Your Catch, Use Every Part of It.
How can fishing be done in a more sustainable way?
For commercial fishers,
rod-and reel-fishing
is a more sustainable alternative to long lining. Another way to prevent overfishing and bycatch is to simply abstain from eating fish and other seafood.
What is Tech used for?
Technology has evolved and shaped our workplaces in many ways, through the adoption of tools like the
internet and email for communications, word processing, spreadsheets and presentations for office productivity, electronic databases for record keeping, and robots and artificial intelligence for automation
.
What are technological devices?
Technological device means any computer, cellular phone, smartphone, digital camera, video camera, audio recording device, or other electronic device that can be used for creating, storing, or transmitting information in the form of electronic data.
What are the types of technology?
While a single piece of technology often overlaps into different areas, there are generally six different categories of technology:
communication, electrical, energy, manufacturing, medical and transportation
.
