2 ty
pes of fishing techniques
- Non-destructive
- Destructive
Almost all non-destructive techniques could fall into destructive category, especially when they are not carried in a proper manner
3 types of non destructive fishing techniques
1.Recreational Fishing
2.Subsistence Fishing
3.Commercial Fishing
Recreational Fishing (non destructive)
- Hook & Line
- Coastal, deep sea, pond, “fishing shop”
- For leisure, family and friends week ends and holiday activity
- Annual competition e.g ‘Pertandingan Memancing Joran’, Bill Fishing Festival
Subsistence Fishing (non destructive)
how, where, for what, example
- Hook and line, cast net, gill net, manual harvesting of shellfish & seaweed-hand gathering/collection
- River, river mouth / estuary, coastal area
- Small scale: for domestic consumption or small side income or both
example: Seaweed = hand gathering / collection
Commercial Fishing (non destructive)
for what, provides what to who? how (what conditions)
- The activity of catching fish + other seafood from wild sources for commercial profit
- Fishing far into the ocean under adverse conditions
- It provides a large quantity of food to many countries around the world
Large scale commercial fishing = industrial fishing
Large scale commercial fishing = industrial fishing meaning
harvest…
Harvest a wide variety of animals especially large and important fisheries worldwide for various species of fish e.g. sardines, anchovy, tuna, crabs, lobster, cod, flounder, herrings, etc.
6 methods used are very efficient:
- Large nets
- trawl
- seine nets
- dredges
- gill nets
- traps
Factory ships are
a large ocean-going vessel with extensive fish processing facilities for processing and freezing fish caught ….
Destructive fishing techniques meaning
Practices that result in irreversible damage to aquatic habitats and ecosystems
- Indiscriminately kill large numbers of fish and other marine organisms in the vicinity
- Damage or destroy the environment
3 examples of destructive fishing techniques
- dynamite or blast fishing
- bottom trawling
- cyanide fishing
Dynamite/ blast fishing meaning
using an explosive device that kills many fishes and other creatures under the sea
Bottom trawling meaning
involves dragging a large net along the ocean floor to catch fish and other marine species living near the seabed
Cyanide fishing meaning
- Potassium cyanide is squirted directly at target fish species (e.g. grouper, Napoleon wrasse, etc.)
- paralyzing them and enabling them to be collected alive
- The cyanide then gets in to currents, it will travel along a reef wall, killing coral and wreaking havoc on marine life
Destructive fishing is common practice especially in poor and developing countries. Is it true? Why?
yes.
- Weak Regulation and Enforcement: Some developing countries lack robust fisheries management regulations and enforcement, leading to overexploitation, illegal fishing, and unchecked use of destructive techniques.
- Limited Education and Awareness: In certain areas, communities may lack awareness of the long-term impact of destructive fishing. Limited education and awareness programs contribute to the persistence of harmful techniques.
- Poverty-Driven Practices: Poverty and food insecurity in communities can prioritize short-term gains over long-term sustainability, prompting engagement in destructive fishing practices that jeopardize fisheries and ecosystems.
