Destructive fishing Flashcards
destruction via pollution
environmental degradation
chemical dumping
chemical dumping and plastics have a drastic effect on marine life and ecosystems
destructive fishing methods
Destructive fishing includes practices that leave marine populations irreversibly damaged and can destroy entire habitats for fish and other organisms.
Destructive fishing includes overfishing, bottom trawling, blast fishing and cyanide fishing.
overfishing
the practice of fishing at a rate that is unsustainable, leading to the depletion of fish populations.
causes of overfishing
- the open access to the ocean and the absence of regulations and monitoring of the water
- slack management
- current rules and regulations are not strict and do not mark a limit on intake
solutions of overfishing
- It should be mandatory to report intake and there must be a maximum limit that is determined by biologists
- stronger monitoring of the ocean
effects of overfishing
Overfishing causes a cascade of effects in marine communities that can destroy habitats and result in the loss of biodiversity both in terms of overall abundance and species richness.
Not only does overfishing destroy marine ecosystems, but it also impacts food security for people by threatening the long-term food supply.
Impacting the livelihoods of coastal and island communities -> economic losses, increased poverty
blast fishing
It involves using explosions to stun or kill large schools of fish for easy collection.
effects of blast fishing
- The explosions often destroy underlying ecosystems from the strength of the blast
- one of the biggest threats to coral reef ecosystems
bottom trawling
Bottom trawling is a method that uses a large net that scrapes against the ocean floor to collect large groups of fish
effects of bottom trawling
The problem with bottom trawling is that it is unselective in the fish it catches and severely damages marine ecosystems.
Many creatures end up mistakenly caught and thrown overboard dead or dying
