Context:

  • Kerala will impose a 52-Day trawling ban from June 9, 2021.

About:

  • Ban on trawling operations during the monsoon is a measure to conserve marine fish resources.
  • Monsoon is the spawning (release or deposit eggs) season of many fish species.
  • However, ban is opposed by several fisherman groups as it makes an impact on their income level.
  • Trawling is one of the most common methods of fishing.
  • Trawl nets are designed to be towed by a boat through the water column (midwater trawl) or along the sea floor (bottom trawl).
  • Bottom trawls (also known as demersal trawl) are used to catch fish and prawns that live on or near the sea floor.

Issues:

  • Environmental: Bottom trawls might result in removal or damage of sedentary living organisms (including seaweed and corals).
  • Strained- relations: Bottom trawling by India fisherman in Palk strait has been a major issue with Sri Lanka, which has banned it back in 2017.

Other measures taken to wean away fishermen from deep-sea trawling

  • Schemes promoting seaweed farming and sea-cage farming.
  • Subsidy for conversion of trawler into resource specific deep-sea vessel.
